5 Good Reasons Why Hybrid is the Logical Choice in Futureproofing Commercial HVAC Building Design

Sunday 22nd of October 2023
Choosing revolutionary R32 Hybrid when designing HVAC systems for commercial buildings, can ensure energy savings, reduce the volume and the use of ozone-depleting refrigerants, offer better user control as well as peak loading reduction.

1. Focus On Energy Savings

R32 Hybrid systems are renowned for their exceptional energy-saving capabilities, making them a smart choice for modern buildings. One of the key advantages lies in their heat recovery functionality, which surpasses traditional chillers. These systems efficiently recover both heat and cooling energy from various zones within a building, ensuring no wastage.

Unlike conventional chillers, where the heat is typically rejected into the atmosphere, R32 Hybrid systems harness this valuable resource, further enhancing their energy efficiency and sustainability. This innovative approach not only reduces energy wastage but also contributes to a more environmentally responsible HVAC solution.

R32 Hybrid systems typically boast higher Seasonal Energy Efficiency Ratios (SEER) and Coefficient of Performance (COP) when compared to conventional chillers with electrical reheats on VAV solutions.

This translates to significant reductions in energy consumption and operating costs, leading to a more sustainable and environmentally friendly building operation.

2. Reduced Refrigerant Volume

Calculating the reduced refrigerant volume between the R32 Hybrid and the existing chiller can be a complex undertaking due to the different technology types involved. However, it’s valuable to consider the R32 Hybrid as a “Deconstructed Chiller” that harnesses the advantages of VRF (Variable Refrigerant Flow) technology.

The key differentiator lies in the refrigerant itself. R32 refrigerant, utilised in Hybrid systems, boasts a significantly lower Global Warming Potential (GWP) compared to R410A, often used in traditional VRF systems. In fact, R32’s GWP is approximately 66% less than that of R410A.

This substantial reduction in GWP showcases the environmental benefits of the R32 Hybrid when compared to traditional VRF systems. While the technology types may vary, the R32 Hybrid stands as an environmentally responsible choice, aligning with global efforts to reduce greenhouse gas emissions and mitigate climate change.

Regulated Phase Down of CO2 Emissions

GWP is a measure of the warming potential as compared to CO2 which has a unitary GWP of 1. R32 refrigerant is zero ozone depleting and has a GWP 66% less than R410A.

For example, R410A will hold 2,088 times more heat when released in the upper atmosphere than the equivalent amount of CO2 would.

R32 refrigerant is being adopted by Mitsubishi Electric as an important step in the process towards the ultimate goal of a zero ODP, zero GWP, efficient, safe and non-toxic refrigerant.

3. Reduction of Ozone Depleting Potential Refrigerants (R32)

R32 Hybrid systems represent a significant leap forward in environmentally responsible HVAC solutions. These systems leverage R32 refrigerant, which has a remarkably lower GWP and zero ozone depletion potential compared to R22. This transition aligns seamlessly with global efforts to mitigate climate change and ozone layer depletion, notably supported by the Kigali Amendment to the Montreal Protocol.

New Zealand, as a signatory to the Kigali Amendment, actively participates in these global initiatives. By adopting R32 Hybrid systems, which offer reduced refrigerant volume and a more sustainable approach to HVAC, we not only ensure efficient heating and cooling but also contribute to a cleaner and greener future, in line with international commitments.

4. Better User Control/User Interface

R32 Hybrid systems offer a distinct advantage in terms of user control and user interface, greatly enhancing human comfort and convenience in the HVAC industry. One key highlight is their integrated control system that seamlessly connects all system components. This eliminates the need for expensive third-party controllers, a common requirement in chiller systems where different components, such as compressors, condensers, evaporators, valves, and all the third-party sensors, often necessitate separate controllers.

With R32 Hybrid systems, users benefit from simplified and streamlined control, which not only enhances user experience but also reduces complexity and costs. This integrated approach ensures that the system operates harmoniously, without the added challenge of managing multiple controllers for various components.

In essence, R32 Hybrid systems empower users with better control and user-friendly interfaces by seamlessly integrating control across critical components, sparing them the expense and complexity associated with separate controllers found in traditional chiller systems. This not only improves the efficiency of the HVAC system but also elevates the overall comfort and satisfaction of building occupants.

5. Peak Loading Reduction

Peak loading reduction plays a crucial role when comparing traditional chillers for cooling and electric reheats for heating against the R32 Hybrid with heat recovery capabilities.

In this scenario, opting for electric heaters for heating purposes proves to be a more expensive approach when contrasted with the heat recovery mechanism inherent in R32 Hybrid systems.

The R32 Hybrid excels in efficiently recovering heat from different zones within a building, making the most of the energy already expended for cooling. This heat recovery process not only reduces energy wastage but also translates into significant cost savings.

Importantly, the R32 Hybrid is capable of extremely high performance at low turn-down capacity, making it a more effective solution for times when not all the load is required, providing greater flexibility in building usage.

It's Time to Change our Refrigerant Choices

Friday 29th of September 2023
Selecting refrigerant driven HVAC plants based simply on capital cost is easy, but short-sighted. Have you ever considered the potential service delivery risks, or the financial and environmental repercussions of these decisions on the future? It’s time to move away from our reliance on the “safe” relatively benign HFC refrigerants we have all become used to.

The Refrigerant Landscape in Summary:

  • HFC phasedown by over 80% by 2037
  • ETS government tax to increase in the future
  • Lower GWP refrigerants are more flammable
  • Refrigerant standards require expensive safety systems, that require ongoing maintenance

Industry Impact of International HFC Phasedown is Significant

The Kigali amendment to the Montreal Protocol is driving the phase-down of HFC gases, which contribute to global warming. New Zealand must reduce HFC gas usage by over 80% by 2037.

Refrigerant Import Rate vs. Consumption Rate

The rate of refrigerant usage is projected to exceed the allowable import amount for servicing by 2026. Switching to lower Global Warming Potential (GWP) refrigerants pushes this crisis date out further.

The Emissions Trading Scheme (ETS)

To effect change, the Emissions Trading Scheme (ETS) imposes a government tax on refrigerants based on their GWP. ETS levies are based on NZ carbon unit cost. Higher GWP refrigerants incur greater ETS levies, with levy rates projected to increase significantly in the future.

Data released in 2021 by the Climate Change Commission indicates that the carbon unit price will need to be over $NZ138 per tonne by 2030 and $NZ250 per tonne by 2050.*

*Source: Bluenotes, "What’s driving the carbon price in New Zealand?".

ETS Cost Impact on Refrigerants

  • Current ETS cost for an 11kg jug of R410A is around $1,560, resulting in a sell price of approximately $2,700 per jug.
  • Industry projections suggest that by 2025, R410A ETS costs could increase to $170/kg, leading to a sell price of around $5,500 + GST per jug.
  • By 2030, if the ETS cost continues to rise at the same rate, it could reach $300/kg for R410A, resulting in a sell price exceeding $12,000 + GST per jug (if you can still get it).

Think about refrigerant costs to charge a VRV / VRF system which would commonly have ~30-40kg of R410A in it. If this system needed to be recharged in 5 years due to a refrigerant leak, the gas could cost upwards of $20,000. In 10 years this could be up to $50,000.

Common HVAC Refrigerants

Lower GWP Refrigerants are More Flammable

Proposed bans on higher GWP refrigerants in specific market categories will lead to the adoption of lower GWP but more flammable/toxic alternatives – posing challenges related to safety and risk mitigation.

Refrigerant Safety Requirements Standard

The NZS 5149 and NZS 60335 standards restrict the use of refrigerants to minimise dangers to occupants, property, and the environment. Directors and business operators can be held liable for breaches under the Health and Safety at Work Act 2015.

Expensive safety systems, including alarms, ventilation systems, shut-off valves, and pressure relief valves, are required by NZS 5149 / NZS 60335. These need ongoing maintenance throughout the life of a building.

This leads to higher operational expenditure for maintenance on large charge direct systems such as VRV.

Future Safety Regulation Challenges

Safety regulations for refrigerant products in overseas countries are becoming stricter, and New Zealand is likely to adopt these standards in the future, necessitating compliance with the latest safety directives.

The industry needs to anticipate future changes by developing products, infrastructure, and safety legislation. Training courses, installer registration, and qualification registers will be necessary.

Hydronic solutions such as Mitsubishi Electric R32 Hybrid or chillers running low GWP refrigerants are seen as a viable path forward in the industry to mitigate these challenges.

Embracing the Future: The Journey to Decarbonising Water Heating in New Zealand

Wednesday 20th of September 2023
As New Zealand sets its sights on a greener, more sustainable future, the quest to transition away from environmentally damaging fossil fuels presents a unique challenge. Among the conundrums faced, a significant one revolves around the need to revolutionise the way we heat water. With the country embarking on a phasedown of gas usage and ambitious plans to reduce reliance on fossil fuels over the next 15 years, the spotlight now turns to finding an eco-friendly, future-proof alternative to gas water heating in homes.

Enter the Almighty Heat Pump

Just as heat pumps have experienced exponential growth since the 2000s, we now witness the emergence of Hot Water Heat Pumps poised to follow in their footsteps. The potential is vast, given that approximately 340,000 homes1 in New Zealand currently use gas to heat their water, emitting over 200,000 tonnes of CO2 per year2. Additionally, there are around 1 million direct electric cylinders1 utilised for water heating, contributing a staggering 400,000 tonnes of CO2 annually3.

The government recognises the significant impact of hot water production on residential energy consumption and carbon emissions. With plans to reduce NZ's carbon emissions by 2050, there is a lot of work to do to reach net-zero.

2Based on E3 Policy Framework and emissions factor of 0.194 kg CO2-e/kWh from “Measuring Emissions” from Ministry for the Environment – Year 2023.
3Based on E3 Policy Framework and emissions factor of 0.120 kg CO2-e/kWh from “Measuring Emissions” from Ministry for the Environment – Year 2023.

Moving to Hot Water Heat Pumps Makes Sense

To address this critical issue head-on with both new builds and replacing existing systems, means choosing eco-conscious solutions like the Ecodan QUHZ CO2 Hot Water Heat Pump - a hot water heat pump that utilises more environmentally-friendly CO2 refrigerant. The impact would be nothing short of revolutionary, reducing carbon emissions by an astounding 74%**. Considering that water heating accounts for approximately 30%**** of a household's total operational carbon footprint, this step alone takes us closer to solving New Zealand’s environmental challenges.

It is worth noting that New Zealand's commitment to renewable energy sources is at an all-time high, with a current share of 90% from renewables†. The nation strives to increase this share to an impressive 95% by 2050, an endeavour that will ensure that electricity use, even with the transition to heat pumps, will leave a minimal carbon footprint compared to gas.

The Future Refrigerant Landscape Paving the Way for CO2 Hot Water Heat Pumps

As a result of the move to net-zero carbon emissions, phasedown of high GWP refrigerants is inevitable. The industry has already seen the move from R22 to R410A to R32 and with A3 refrigerants being the next step, change seems to be an unavoidable part of the heat pump industry. However there is a tangible and future proof solution available right now, CO2 (OR R744) with a GWP of just 1, meets all current and future regulations to phase down refrigerant. Being a natural gas, R744 is something we are all use to, it is what we breathe out into the atmosphere and it's what feeds plants to grow and now CO2 can be used as a naturally occurring, non-flammable and stable refrigerant fluid solution for hot water heat pumps.

Continuously Clean Air All Year-Round

Wednesday 27th of July 2022
We are all aware that regularly cleaning indoor surfaces is an important part of keeping a healthy indoor environment, but what about cleaning the air we breathe?

It's easy to think of pollution as a problem that just exists outdoors, yet it's the same air containing traces of dust, pollen and other microscopic particles that finds its way inside our homes, offices and enclosed spaces.

To add to this, dust, pet dander, chemicals, airborne illness and allergens are common contaminants already found indoors. In fact, indoor air can be up to five times as polluted as outdoor air! Indoor air quality is an increasing concern, especially in the spaces we share with others, so finding ways to circulate and purify the air we breathe is more important than ever.

Introducing the Mitsubishi Electric ElitePure Air Purifier – Cleans Air with a Push of a Button

The ElitePure Air Purifier features a compact and portable design with high performance 4-Step Air Filtration System to intuitively remove smells, dust, allergens, and other common pollutants.

Next Generation 4-Step Filtration

The ElitePure maintains healthy air circulation indoors by pulling dirty air in and passing the air through a high performance Filtration System, in 4 steps.

These filters trap pollutants such as dust, pollen and bacteria and supply clean air back into the room. This provides the ultimate peace of mind and ensures a healthier and cleaner living environment.

Quick and Powerful Air Renewal

One of the main parameters used to establish the effectiveness of an air purifier is the CADR or Clean Air Delivery Rate. The bigger the CADR number the quicker the air purifier is able to clean the air in a room.

The Importance of Good Home Ventilation

Monday 25th of July 2022
Creating a healthy living environment is important when renovating or building a new home – so, in addition to efficient heating and cooling, this should include the optimum amount of fresh air. Regional Sales Manager, Evan Rayner explains.

Current building regulations now demand homes to be built more airtight as they are subjected to higher insulation standards, but this often means a lack of natural ventilation and can lead to a build-up of moisture-laden stale air within the home.

The option of leaving doors or windows open to allow more fresh air to enter is often not the solution from an outdoor noise, weather or security perspective and can make heating the home less energy efficient.

Why it Pays to Ventilate

I've noticed a big shift in perceptions in recent years, ventilation is no longer just a nice to have. It's becoming an essential part of a modern build, not just in terms of meeting codes.

Mould and dampness can compromise both building materials as well as furnishings inside the home, especially in window sills, curtains and carpets. A quality balanced pressure ventilation system such as Mitsubishi Electric's Lossnay Range, is a small price to pay to protect a homeowner's overall investment in the years to come. It actually doesn't cost a lot to buy or to even run a ventilation system and I know from experience with our Mitsubishi Electric Lossnay Systems they will likely last you over 20 years.

I've been to a house that was only two years old with mould and mildew issues. It was so bad that you could see the lines of timber joins on the wall, through the wallboard. It was obvious the occupants weren't opening their windows to let enough fresh air in – what a waste of brand new furnishings and materials for what would have likely been less than 1% cost of the overall build to have a ventilation system.

After installing a Mitsubishi Electric Lossnay Fresh Air Heat Recovery Ventilation System into the property, those lines were gone within the week and a month later the owners described it as living in a completely different house.

Mitsubishi Electric: Ventilation Solutions to Suit Most New Zealand Homes

Mitsubishi Electric offers a full Lossnay Fresh Air Heat Recovery Ventilation range from in-ceiling whole home heat recovery solutions like the LGH or Vertical range, to ducted and wall mounted single room VL100 models.

Lossnay can even be integrated with a Mitsubishi Electric Ducted Heat Pump System for increased energy savings – recovering the energy from stale air to pre-heat or pre-cool incoming fresh air, reducing the amount of additional heating or cooling required. A combined ducted system can be a cost-effective option for homeowners.

But not every home needs a large ducted unit and sometimes the roof space doesn't allow for one. This is where our range of single room models are a hit as they allow Lossnay Ventilation to be installed in apartments, studios and spaces with limited roof space.

Lossnay Single Room is available as either a Ducted Unit or as a Wall Mounted model. Our Lossnay range means we can find a solution to suit most New Zealand homes.

Ventilation is an Investment in your Health and Home

We all know cooking, washing and condensation can make a home damp, but the biggest contributor is your breath and there is no avoiding that!

Mitsubishi Electric's Lossnay Fresh Air Heat Recovery Ventilation range is not only a small price to pay to protect end user's investment, it's vital for the health of the home and the wellbeing of the occupants. Click here to learn more about the range.

There are two styles available – the Jet Towel Slim and Jet Towel Smart. And with a range of colour options available, it means that there is a stylish solution to fit any commercial bathrooms aesthetic.

Say Goodbye to the Costly Mess of Paper Towels

The cost of constantly replacing paper towels each day can be staggering. Because Jet Towels only use electricity to operate, they can eliminate the cost of paper towel maintenance and instead utilise high-speed air to quickly and effectively dry hands.

As a result, they are the more environmentally friendly, cost-effective and hygienic solution for commercial bathroom spaces across schools, universities, office spaces, hotels, shopping centres and other public facilities across New Zealand.

In addition, switching to a Jet Towel not only keeps commercial bathrooms cleaner but also sends a positive message to users about a facility’s attitude towards the environment.

LGH-RVS Lossnay Sensible Heat Recovery Ventilation Range

Monday 18th of July 2022
The new LGH-RVS Sensible Lossnay range from Mitsubishi Electric features a non-permeable Lossnay core, allowing you to bring fresh filtered air in and draw stale air out from high moisture areas, with the added benefit of sensible heat recovery to maximise efficiencies.

The Ultimate Heat Recovery Ventilation System

The LGH-RVS Lossnay range is perfect for higher humidity environments such as bathrooms, kitchens and laundries as well as commercial applications such as gyms, healthcare centres, schools and offices. Boasting a range of enhanced features including an integrated bypass damper for free cooling, optional CO2 sensor control and easy control interlock with Mr Slim and City Multi systems – it’s the ultimate heat recovery ventilation system for all areas.

Easy Installation

Being lightweight is one of the most important factors for installation. The light chassis of the LGH-RVS Series can provide a huge advantage in terms of cost and safety of installation.

Easy Drain Piping

The unit features one drain pipe terminal for both supply air (SA) and exhaust air (EA). A condensate trap is not required as the LGH-RVS unit features an internal backflow prevention device and an inclined drain pan, which not only helps with installation, but also reduces the risk of mould and odour.

Flexible condensate pipework and a 360° swivel drain pipe connection means installation can be incorporated into building designs with the ability to avoid obstructions and be set out of the way against walls.

Low Noise Operation and Energy Efficiency

Starting from a super quiet 18dB(A)*, the LGH-RVS Series operates with incredibly low noise thanks to a specialised sirocco fan produced by Mitsubishi Electric. This unique fan balances airflow and static pressure to minimise noise levels. The series also incorporates a high-efficiency motor to reduce power consumption.

Optional Parts for Enhanced Operation

How to Minimise Indoor Sound Levels with the Vertical Lossnay

Thursday 14th of July 2022
The Vertical Lossnay Fresh Air Heat Recovery Ventilation System is the ideal solution to protect homeowners from future consent conditions around indoor noise management.

VL100 Unit in Laundry

Councils around New Zealand are starting to introduce consent conditions around the management of indoor noise levels in habitable spaces. With housing density increasing, opening windows to naturally ventilate a home is often not possible or leads to sound levels that exceed requirements outlined in district plans and consent processes. To protect a homeowner from these and other future compliance changes, they should consider installing a Mitsubishi Electric low-noise Vertical Lossnay Fresh Air Heat Recovery System.

Urban Density is on the Rise in NZ

Consents for townhouses, flats, and units are growing at over eight times the rate of standalone dwellings (46.6% versus 5.7% for the year ended April 2022)*1. These new figures are indicative of the changing residential landscape across New Zealand towards more higher density living.

New Zealanders can also expect to see more medium density homes being built across more of our major cities thanks to the government’s new Medium Density Residential Standards. The standards, which come into full effect from August 2022, will enable people to build up to three units and three storeys on most sites in Auckland, Hamilton, Tauranga, Wellington, and Christchurch without the need for resource consent.

Aparments

Homeowners are Insulating from Noise in Mixed-Use Environments

Medium density housing developments are increasingly being built in mixed-use environments that contain both residential and commercial premises (such as office, retail or hospitality) or close to major community infrastructure (such as airports or ports). So what does this mean for homeowners and occupants residing in these areas?

Issues can arise when occupants become affected by the noise from existing activities already occurring in the area – this is referred to as reverse sensitivity. To address the effects of reverse sensitivity, it is more practical for the homeowner to insulate the home from noise, than it is for existing commercial businesses to comply with acceptable residential noise levels.

Specific Precautions for Indoor Noise Limits Introduced

Section 16 of the Resource Management Act 1991 places a general duty of care on all occupiers to adopt the Best Practicable Option (BPO) to ensure noise emitted from any site does not exceed a reasonable level. Furthermore, many district plans now require specific precautions to be taken by the noise receiver to avoid adverse noise effects.

The Hamilton City Council for example, have set noise limits for the construction of new buildings in noise-sensitive areas such as the Central City Zone and subdivisions within the stipulated contour line from the Waikato Expressway. These limits ensure the building containing the noise sensitive activity is designed and constructed to meet an indoor design sound level of 35dB LAeq(24hr) in bedrooms and 40dB LAeq(24hr) in all other habitable rooms.*2

Why Does Ventilation Need to be Considered?

The G4 Clause of the New Zealand Building Code requires habitable spaces in a home to be provided with adequate ventilation consistent with their maximum occupancy and intended use.

Occupants of medium density homes, particularly in mixed-use environments are often unable to naturally ventilate their home due to noise and security issues that arise from opening windows.

Offices with business people walking outside

While acoustically insulated windows can help reduce noise, it is not enough to stop indoor sound targets being exceeded in rooms with open windows. This is where a mechanical ventilation system should be installed that complies with the requirements of the G4 Clause.

Vertical Lossnay Fresh Air Heat Recovery Ventilation – an Ideal Low-Noise Solution

The Mitsubishi Electric Vertical Lossnay Range is designed specifically for the New Zealand housing market and makes energy efficient, super-quiet ventilation accessible to even more homes such as townhouses and apartments.

From an ultra quiet 15dB*3, the Vertical Lossnay can operate well within indoor noise limits that are starting to be introduced in district plans and consents (such as the Hamilton City Council example). By installing the low-noise Vertical Lossnay system a homeowner can have greater protection against future compliance challenges.

Furthermore, because of the slimline, vertical upright design, the Lossnay Ventilation System is not limited to an in-roof installation. Apartments and townhouses often have limited roof space, but with the Vertical Lossnay’s small upright footprint it can be placed in the garage or a cupboard in the kitchen. Now whole home ventilation can be installed and integrated in the overall building design without limitations.

e-Series Modular Chillers – The Efficient Process Heating and Cooling Solution for Food and Beverage Industries

Wednesday 23rd of March 2022
When storing, fermenting and processing food and beverages, temperature control is often the key to ensuring overall product quality. While chiller systems have been used for decades for process heating and cooling, there is an increasing pressure on energy efficiency and running costs - those in the horticulture, viticulture and food manufacturing industries now need a low-carbon and cost effective option to meet the demands of today.

The e-Series Modular Chiller Range from Mitsubishi Electric is a modern update on a traditional chiller system, offering advanced temperature control, unparalleled efficiencies and a wide operating temperature range, all in a flexible modular format that is ideal for New Zealand Food and Beverage businesses such as wineries, breweries, orchards, dairy factories and other commercial stores.

Disrupting the Status Quo of Chiller Hire

Often directed by season, produce growers and wineries will hire their large capacity chillers in peak production months to avoid the cost of maintenance, running energy costs when requiring low loads in off-peak months and reduce the space needed for a permanent plant room to house the chiller.

However, with the energy efficient and flexible Mitsubishi Electric e-Series Modular Chiller Range, it can now be cost effective and convenient to own rather than hire to meet processing needs.

Featuring a Modular Format to Support Growth

Instead of a large, single chiller, up to six smaller modules can be connected together to provide the same level of output. This modular format and compact design reduces plant space requirements as well as simplifying logistics and installation.

Model kW output per module Maximum kW output with 6 connected modules
P900 90kW 540kW
M1500 150kW 900kW
M1800 180kW 1,080kW

Furthermore, the modular nature of the chillers means that owners can upscale as their operation grows over time without having to invest in a large capacity unit up front to compensate for potential expansion.

Optional Built-in Header Piping Reduces Space Requirements and Offers Easier Installation

Header pipes, which are required to connect units together, can be built into the unit. This feature reduces the space requirements needed for a chiller plant. Multiple units are easily connectable by the internal headers, eliminating the need to procure water pipes for connecting the units and reducing installation work.

Easy Maintenance without Delaying Production

When installed using the inbuilt headers, individual modules can be isolated from the water circuit thanks to the inbuilt isolation valves. This allows for maintenance to be carried out while the other modules remain in operation.

This is crucial in peak seasons when a stop to controlled cooling can result in loss of produce and revenue. During vintage season when wineries have to harvest thousands of tonnes of produce in a short timeframe, if the picked grapes warm up too much they'll start to ferment early, which ruins the flavour and quality of the wine.

Wide Operating Temperature Range

Chillers are relied upon in food and beverage industries to keep a constant temperature, especially in factory environments that can cause hot indoor temperatures.

It is imperative that dairy milk is cooled and remained constantly chilled to a level where bacteria cannot grow – in fact the New Zealand Government requires raw milk supply to be kept at or below 6°C* prior to manufacturing. This allows dairy products to be transported, stored, and manufactured without spoiling and ensuring product is safe for later consumption. Breweries also rely on particular temperatures for fermentation; yeast must not get too hot (over 40°C) or it will die and taint the flavour of the beer.

The Inverter controlled fan and compressor of the e-Series Chiller enables precise control of outlet water temperatures, resulting in stable operation. M1500 and M1800 models deliver chilled water as low as 4°C, while with Glycol the P900 delivers chilled water down to -10°C without freezing. Both models have options to deliver heated water up to 55°C.

* Ministry of Primary Industries, 'Animal Products Notice: Raw Milk Products Specifications' 10 September 2020. https://www.mpi.govt.nz/dmsdocument/1005-Animal-Products-Notice-Raw-Milk-Products-Specifications

The P900 e-Series Model Provides Sub-Zero Cooling

The P900 supports a wider outlet water temperature setting down to -10°C without freezing through the use of Glycol. This means in a winery application, an e-Series P900 Chiller can chill wines to sub-zero temperatures without freezing the insides of the winemaking vessel.

Energy Efficient Performance with Advanced Controls

Typical chiller control systems allow units to run at a maximum capacity while other units are in standby during part load. The Mitsubishi Electric e-Series Chiller Range is designed to optimise chiller compressor frequency based on the number of connected units, maintaining the highest part load efficiency possible.

When the Overall System Load is 50%

Typical Chiller Control

e-Series Modular Chiller Range with Optimum Frequency Control

With up to six units operating in one bank, this function improves system efficiency when operating at low to medium loads. Furthermore the run time of each unit is equalised by the control system, this prevents uneven wear on the units and extends the lifespan class= of the system.

The Versatile e-Series Modular Chiller Range

Why is CO2 Refrigerant the Future of Hot Water?

Monday 13th of December 2021
The F-gas Regulation aims to reduce F-gas emissions by two thirds of 2010 levels by 2030, by improving the leak-tightness of equipment, promoting the use of more environmentally friendly alternatives to F-gases and capping sales of HFCs on the EU market through an HFC phase-down. HFC target limits are already in place in Europe which has a dramatic effect on global manufacturers and the phase out of R410A has already started. HFC EU limits for single split air conditioning (<3kg of F-gases) is GWP = 750 by the year 2025.

*Based on the Kigali Amendment to the Montreal Protocol ratified in October 2019. Ministry for the Environment. 2017. 7. Wellington: Ministry for the Environment.

The R410A Phasedown

As a result of this phasedown, we are seeing refrigerants with lower GWP (in particular R32) in many air conditioners and hot water heat pumps. It won’t stop there, that’s just the interim refrigerant before moving to natural gases, including some controversial flammable gases such as Propane.

We do have an option that is here already, CO2 refrigerant. It is a natural gas. It is what we breathe out into the atmosphere and it's what feeds plants to grow. CO2 can also be used as a naturally occurring, non-flammable and stable refrigerant fluid solution for hot water heat pumps.

It is non-toxic (at reasonable concentrations) and with a Global Warming Potential (GWP) of 1, it is also the base refrigerant that all other refrigerants GWP numbers are based on and will future-proof the way homes and businesses heat water.

Mitsubishi Electric CO2 Hot Water Heat Pumps are Leading the Way

It's a progressive move for most manufacturers to change refrigerant to a lower GWP - Mitsubishi Electric has already begun to take the lead with hot water heat pumps utilising CO2 refrigerant.

Ecodan QUHZ Hot Water Heat Pump for Domestic Potable Hot Water and Space Heating

The QUHZ Ecodan is an advanced hot water heat pump that can provide both domestic hot water as well as supply hydronic space heating through radiators or underfloor heating.

Utilising CO2 as a natural refrigerant, it is the number one environmental choice for domestic hot water heating and an alternative to gas and direct electric systems.

The Ecodan QUHZ Hot Water Heat Pump is revolutionising central heating and domestic hot water technology in New Zealand.

Ideal for New Build Townhouses due to Low Noise Operation

With space often being a premium on new build development sites, Ecodan QUHZ will operate discreetly where dwellings are in close proximity to each other. The QUHZ Outdoor unit provides very quiet operation as low as 43dBA (SPL).*2

Specific outdoor unit design features enable quiet operation to be maintained in all modes of operation and all ambient conditions as well as allows improved flexibility for the installation locations. The Ecodan QUHZ will help residential areas that are particularly sensitive to outdoor noise to benefit from renewable heating technology.

A Smart Move for Developers

Not only is the outdoor unit quiet, the compact indoor cylinder provides the equivalent of 250L of hot water using plate heat exchanger technology drawing heat from the 200L thermal store. Separated from the stored water, instant production of hot water means there is no risk of legionella while achieving up to 70°C domestic hot water.

In addition, the QUHZ can heat the whole home easily with temperatures up to 60°C for radiators or underfloor heating. With combined domestic hot water, the QUHZ is the low carbon footprint option for new homes. By future proofing and adding value to the property, it is the number one choice for developers, architects and builders alike.

QUHZ Key Features

  • Rated domestic hot water mode capacity 5kW*1
  • High efficiency domestic hot water production COP=3.7*1
  • Class leading low noise operation at 43dBA outdoor unit *2
  • Energy monitoring as standard
  • No stored water draw, no risk of legionella
  • Pre-plumbed and wired for faster installation
  • No refrigerant pipework into the house, water connections only

QAHV is the Commercial Solution for Generating High Temperature, High Volume Hot Water

There’s usually an argument to say that heat pumps can’t produce the higher temperatures that gas boilers can achieve, but with CO2 refrigerant, temperatures up to 90°C can be produced in ambient outdoor temperatures as low as -25°C.

The high discharge temperature from compressing the CO2 gas means we can now achieve high temperatures and achieve high efficiency because the CO2 refrigeration cycle works best with a large temperature difference. For sanitary hot water production this technology is the way forward, to be able to reach high temperatures for wash downs, leisure facilities, potable hot water and for the industry to seriously meet carbon reduction targets. QAHV is certainly the solution.

QAHV Key Features

  • Rated Heating Capacity of 40kW
  • High efficiency (Achieved COP 3.88*3 )
  • Supplies high temperature hot water of up to 90°C
  • Operable even at low out door temperature of -25°C
  • Utilises natural CO2 refrigerant which has zero Ozone Depletion Potential (ODP) and has a Global Warming Potential (GWP) of 1
  • Uses a unique twisted and spiral gas cooler to enhance energy efficiency
  • Compact dimensions, minimising plant space
  • 16 units can be grouped together to form a bank of 640kW rated heating capacity

The Shift to CO2 is Happening Now

We will see more CO2 hot water heating products in the future and these products will no doubt become the norm for generating potable hot water and efficiently heating our homes.

6 Key Ventilation Tips for Homeowners to Consider

Monday 13th of December 2021
Creating a healthy environment is important when renovating or building a new home. Your customers will value your advice and expertise in all aspects of ventilation. Make this your competitive advantage and share the following 6 tips with them, to ensure they invest in the best ventilation solution for their health and home.

1. Talk to a ventilation expert early in a new build planning process

It can be easy for homeowners to jump straight into the design aspect of planning, however this can often be the first mistake made. Too often people consider ventilation once their build is in progress or even complete and find their plans make installation difficult, more costly and often result in a make do application that isn't what they were initially after.

By bringing in a ventilation expert in the early planning stages you can save future headaches. Always ensure a ventilation system is integrated into plans to maximise efficiencies. Ducted air conditioning with combined Lossnay Ventilation is a perfect example of something that is best to bring in an expert early in the process for. Installation, ducting and wiring is far easier to manage before the ceiling is put in place, allows flexibility with outlet placement and Lossnay's heat recovery will add further efficiency to the air conditioner when in operation.

2. Make use of what is free with heat recovery technology

Ventilating our indoor spaces is more important than ever, but they should also be as energy efficient as possible.

Mitsubishi Electric's unique heat recovery technology recovers up to 85% of the heat energy from the outgoing stale air which is then used to pre-warm (or pre-cool) incoming fresh air. Why not take that warm air from the sunniest side of the house to pre-warm the outdoor air being filtered in? Or use the air you have already paid for to heat.

Heat recovery means any heating or cooling appliance does not have to work as hard to reach the desired room temperature – providing savings on energy bills.

3. Place ventilation ducts and grilles to maximise efficiency

Placement of ducts and grilles are almost as important as the system behind it.

Often ventilation systems are not working as efficiently as possible because they are drawing air from the coldest parts of the home and not taking advantage of those areas which are naturally warmer. It goes back to heat recovery, the best thing you can do is make use of that free energy.

4. Not all air is created equal. Fresh outdoor air rather than air from the roof-space is key to ensuring indoor air quality

To achieve compliance with the Ventilation Standard NZS4303:1990 of the New Zealand Building Code, a building's ventilation system is required to draw fresh air from the outside in order to achieve acceptable indoor air quality.

Not all air is created equal. The absence of significant air movement common in attics means the air is likely to be stale. In addition, build-up of dust, dirt and other contaminants such as mould, insect and rodent droppings makes this air much harder to filter before it is distributed through your home - it's not what you want to be breathing in.

All products in our Lossnay Ventilation Range draw fresh air from outside and filter this to maximise air quality. While systems that draw from the roof are less common since the standard was introduced, these systems can still be found in the market to target those wanting a retrofit solution for an older home.

5. Meet the requirements of the home, not just the Building Code

The New Zealand Building Code often asks for the bare minimum and by using this as a benchmark, the actual ventilation requirements of the property might not be met. Our code in New Zealand asks for 0.35 air changes per hour, however if you are really wanting to maximise your homes air quality this should be higher. When designing a Lossnay system, authorised Mitsubishi Electric installers refer to the higher UK standard of 0.43-0.5 air changes per hour.

Capabilities like this are important as they can easily be overlooked by price, but a low performing system can result in unmet expectations and ultimately a wasted investment.

6. Complement your system with a separate exhaust fan for wet areas such as bathrooms and laundries

While many systems including Lossnay can draw from moisture laden air, to get the most energy efficiency out of your heat recovery system, homeowners should install a separate Mitsubishi Electric Ducted Exhaust Ventilation Fan in wet areas such as bathrooms. While a bathroom can be warm during showers, when not in use they are often the coldest rooms in the home - so why combine that cold air to the air you are hoping to recover heat from and reduce the overall temperature you can recover? Exhaust fans do an excellent job at removing steam and moisture quickly and are turned off when not needed, saving energy use.

­­­Black Diamond Technologies Limited – Celebrating 40 Years in New Zealand

Tuesday 7th of December 2021
On the 9th of November 2021, Black Diamond Technologies Limited (formally known as MELCO) reached an important milestone – 40 years of providing New Zealanders with the leading edge technologies of Mitsubishi Electric products into New Zealand homes and businesses.

To celebrate, we share our story from the beginning and our thoughts on how we will continue to shape the industry over the next 40 years and beyond.

In the Beginning

Right from the beginning Mitsubishi Electric manufactured world leading products founded on two key principles: quality and technological innovation. Video Recorders, Colour TVs and Audio Systems were examples of categories where Mitsubishi Electric led the way. Yet in the early 80's those products were not represented in New Zealand, in fact the brand was unknown here.

Ron Woodrow Company Founder

The foresight that led to the introduction of Mitsubishi Electric products in New Zealand by MELCO / BDT came from its founder Ron Woodrow.

Ron began his career at EMI in Wellington. With a keen interest in consumer electronics his attention was drawn to how video recorder technologies were advancing, particularly by Japanese manufacturers. The potential he could see convinced him to take a bold step. Leaving the security of EMI in 1981, Ron along with Pat Feehan set up a new venture called MELTRON to import Mitsubishi Electric products.

Starting off with video recorders, the product range quickly grew to include TVs, Microwaves and computer products.

Impressed with the success, after 1 year Mitsubishi Electric Japan became a 51% partner in the venture and MELTRON was renamed MELCO (Mitsubishi Electric Company). The business grew quickly, with its head office in Wellington; branches were also opened in Christchurch and Auckland.

In 1992, with the departure of Pat Feehan, the then Divisional Manager Ken Lilley purchased these shares and became Director.

Key Defining Mitsubishi Electric Products

The Black Diamond Video Recorder

From the first ever Mitsubishi Electric video recorder that was brought into the country in 1981, the HS-330 Model (pictured below), the brand grew from strength to strength.

In 1988, a new range was launched that featured a distinctive black slimline design and was packed with a host of advanced features. No other video recorder had more up-to-date features for the price. This range became known as the Black Diamond Series and was so popular, that from 1988 to 1998 it was New Zealand's best-selling video recorder brand. The advertising created around the Black Diamond name proved so powerful that it became a sub-brand in its own right, and was even used by other Mitsubishi Electric distributors internationally.

Diva Large Screen Television

1984 saw the introduction of Mitsubishi Electric Televisions. Just like video recorders, it did not take long for New Zealanders to aspire to also have a Mitsubishi Electric TV take pride of place in their lounge. As a result, from 1993 to 1996, the large screen feature packed Diva Collection became New Zealand's best-selling TV range.

The Cube Microwave

Another key defining Mitsubishi Electric product was the Cube Microwave. Introduced in 1985, its unique shape was a real conversation starter and became so popular; kitchens in the day had cabinetry purpose built to fit “the Cube”. As a true mark of Mitsubishi Electric quality, we still receive calls from customers with working Cube Microwaves that require rehoming, 36 years on!

Our Advertising – the “Don't you wish?” Campaign

From a marketing perspective, the philosophy has always been to be the aspirational brand and to have Mitsubishi Electric product seen as the number one choice in every category it contested.

This has involved creating messages that position Mitsubishi Electric products as stylish, advanced and very user friendly. For many years the memorable tag line for virtually all our products was “Don't you wish you had a Mitsubishi?”

The Only Constant is Change

In a business as dynamic as consumer electronics, change is inevitable. Organisations must develop resilience and flexibility to adapt. In 1997 Mitsubishi Electric underwent changes that saw it announce a global move away from TV and video recorder production. These had been important categories for MELCO / BDT however, like its Japanese partner; the New Zealand Company would also have to change. In 1998 the company re-established itself with Mitsubishi Electric, energy efficient, compressor driven products. It did not take long for the brand to firmly establishing itself in the air conditioning, dehumidifier and refrigeration markets, where it is now one of the major and leading players.

Part of this re-invention was also a change in company structure where Ron Woodrow and Ken Lilley bought out Mitsubishi Electric's 50% stake. With this change to 100% New Zealand ownership, MELCO changed its name to Black Diamond Technologies.

A New Generation of Mitsubishi Electric Products

Through the exclusive partnership with Mitsubishi Electric, BDT has enjoyed the advantages of access to category leading technology and energy efficient, environmentally sustainable products with unique features to improve people's lives.

As a result, the company now specialises in the marketing and distribution of Mitsubishi Electric products including Air Conditioning and Heat Pumps, Ventilation, Hot Water Heat Pumps, Dehumidifiers, Refrigeration, as well as a full range of commercial building HVAC (Heating Ventilation Air Conditioning) solutions.

Integral to the successful change in direction was the joining of Darryl Rochester to the Company in 1999. Darryl came with a long history in the New Zealand air conditioning industry and was ready to take on the challenge of establishing Mitsubishi Electric as the leading brand of energy efficient compressor driven products.

Heat Pumps

While the first Mitsubishi Electric Heat Pump System was sold in New Zealand in 1989, real momentum started in 2006. Using the tried and tested marketing philosophy of leading with unique products that take the higher ground, New Zealand's quietest high wall heat pump was launched.

Just like all those years ago, the philosophy of being the aspirational brand and to have Mitsubishi Electric product seen as the number one choice was front and centre for the marketing of Mitsubishi Electric Heat Pumps.

Quietly Superior

The new “quietly superior” advertising campaign that featured the cat and presenter based format was born. And to this day, Mitsubishi Electric Heat Pumps are now unequivocally synonymous with quietness.

Since then, regular unique product ranges were introduced setting new standards in comfort levels. HyperCore Technology was launched in 2009 that was specifically designed for New Zealand's low temperature conditions. Colour options with the Designer Series was introduced in 2011 giving Kiwis an alternative to just white!

And in 2014 driven by the philosophy of smart technology, BDT took matters in their own hands and developed the Wi-Fi Control app in-house for its range of Mitsubishi Electric Heat Pumps sold in New Zealand. The successful advertising campaign was centred around the premise of “Never return to a cold home again” and absolutely changed the way New Zealanders thought about heat pumps.

So What Does The Future Look Like?

Brought to life in 1998, the Environmental Vision 2021 initiative was established by Mitsubishi Electric with a long term global framework for realising a more sustainable planet. Since then, Mitsubishi Electric has reported annually on its environmental objectives and achievements in Japan and globally, to review the progress of the environmental plans of the group.

A key driver of the Environmental Vision 2021 Mandate is striving for the best and the most environmentally friendly use of energy in buildings by developing zero or low carbon technologies that consume the least amount of energy with minimal environmental impact.

Hot Water Heat Pumps

The Mitsubishi Electric Ecodan Hot Water Heat Pump Range launched in 2020 is a good example of a product that already meets this objective. Utilising their expertise and industry leading technology, Mitsubishi Electric has developed a super energy efficient heat pump that combines both hot water heating and room heating through one system.

Just like heat pumps revolutionised space heating in homes in the early 2000's, hot water heat pumps are poised to take the same trajectory. They are set to become the building blocks of tomorrow's environmentally friendly future and BDT is committed to retain Mitsubishi Electric's leading position in the New Zealand market wherever the journey takes us.

Creating New Zealand's Sustainable Future

On average, with buildings accounting for over 20%* of energy consumption and carbon emissions in New Zealand, improving the level of efficiency is of paramount importance.

As the exclusive distributor of Mitsubishi Electric products in New Zealand, BDT seeks to use its position to increase awareness, improve energy use and minimise carbon footprint in the built environment in the most energy-efficient, cost-effective and environmentally friendly way possible.

By constantly challenging everyone involved to combat the issues we all face, BDT and Mitsubishi Electric aim to help everyone address both energy use and carbon emissions, to work towards a more environmentally sustainable future overall.

BDT looks forward to regularly reporting back on how both BDT and Mitsubishi Electric are taking definitive action today, to create a greener world for tomorrow.

Introducing the High Efficiency R32 e-Series Modular Chiller Range

Monday 15th of November 2021
Mitsubishi Electric has extended the e-Series Modular Chiller Range to now include M1500-1800 models that utilise R32 as a low Global Warming Potential (GWP) refrigerant. Comprised of cooling only and heat pump models, the Mitsubishi Electric R32 range of e-Series Modular Chillers allow up to six individual units to be connected together to provide system capacities up to 1,080kW.

A modern update on traditional systems, the R32 e-Series Chiller is Mitsubishi Electric’s most efficient chiller system yet.

The Versatile Solution – Stock Available Now

Available as a cooling only or heat pump version, the e-Series is suitable for both comfort and process cooling applications. The modular design is great for new or replacement projects and ideal for projects with future expansion plans – allowing for a reduced initial capital cost.

Mitsubishi Electric e-Series Modular Chillers are currently operating in New Zealand hotels and commercial buildings, as well as experiencing growth in industries such as horticulture, dairy and industrial processing plants due to its superior efficiency and versatility.

*(BS) Coastal Protection and (-N) built-in header type options available.

Reduced Environmental Impact by Using R32 Refrigerant

With the New Zealand Government’s ratification of the International Kigali Amendment in 2020 sparking a steep phasedown of HFCs, building owners, facility managers and the construction industry have been looking for HVAC systems that deliver high operational efficiency whilst minimising the GWP of the refrigerants used within these systems.

The new R32 e-Series Modular Chillers offer significant environmental benefits over conventional R410A chillers. The use of R32 compatible compressors and flat tube heat exchangers allows for approximately 68% reduction in refrigeration volume and approximately 89% reduction in CO2 equivalent in the EACV-M1500YC(-N)(-BS).

Enhanced Efficiency Through R32-Compatible Inverter Compressor

A new compressor with a suction chamber injection mechanism and an inverter control system that automatically controls the operating frequency realise the use of R32 refrigerant and a wide water operating range.

e-Series Modular Chillers offer significantly improved seasonal efficiency when compared to R410A e-Series machines, which means that they cost less to operate over their lifetime.

Improved Annualised Operating Efficiency

*The values are calculated in accordance with EN14511.

High Performance Flat Tube Heat Exchanger

The use of high performance heat exchangers allows for a greater surface area whilst also keeping the units much narrower than conventional chillers. The inclusion of fins inside the flat tube heat exchanger divides the flow path of refrigerant and improves heat exchange effectiveness. This contributes to greater energy efficiency, reduction in refrigerant volume and a wider operating range.

New Water Side Heat Exchanger With Reduced Pressure Drop

Water Side Pressure Drop is reduced due to the new heat exchanger design. The heat exchanger assembly is complete with drain valve and air vents. These allow for easy air bleeding and draining of the heat exchanger.

Modular Format Ensures Design Flexibility and Reliable Operation

Up to six individual units can be connected together to provide a system capacity from 150-900kW for the M1500 model or 180-1080kW for the M1800 model. Using this modular approach reduces plant space requirements as well as simplifying logistics and installation.

A modular approach also lends itself to a staged installation for future HVAC demands, as modular chillers can be scaled accordingly and are easily replaced.

When installed using the inbuilt headers, individual modules can be isolated from the water circuit thanks to the inbuilt isolation valves. This allows for maintenance to be carried out while the other modules remain in operation.

Advanced Controls for Further Energy Savings

Typical chiller control systems allow units to run at a maximum capacity while other units are in standby during part load. The Mitsubishi Electric e-Series Chiller Range is designed to optimise chiller compressor frequency based on the number of connected units, maintaining the highest part load efficiency possible.

When the Overall System Load is 50%

Typical Chiller Control

e-Series Modular Chiller Range with Optimum Frequency Control

With up to six units operating in one bank, this function improves system efficiency when operating at low to medium loads. Furthermore the run time of each unit is equalised by the control system, this prevents uneven wear on the units and extends the lifespan of the system.

Market Leading Low Noise Levels

The e-Series Modular Chillers are by their nature much quieter than conventional chillers. By utilising highly efficient fan and compressor technologies within a uniquely shaped chassis, the e-Series Modular Chiller range offers low noise levels that are ideal for high density areas such as city centres where commercial and residential buildings mix.

e-Series Coastal Protection Models

While the standard e-Series models come with excellent corrosion resistance, the Coastal Protection e-Series models (-BS) go a step further by treating external panels and other key elements to a higher paint specification, providing further protection from aggressive salt environments often needed in New Zealand.

Easy Control

The water temperature in each module can be controlled using local remote controller PAR-W31MAA or by using centralised controller AE-200E. The AE-200E controller can centrally control up to 24 units or 24 systems connected via M-Net. The maximum number of connectable units can be further increased using EW-50E or AE-50E Expansion Controllers.

NZS5149 – The HVAC Standard You Should Know About

Wednesday 3rd of November 2021
The NZS5149 standard that deals with refrigerant concentration in confined spaces has been around since 2016. It’s important as it affects every new or altered DX system installed in NZ – but it is largely overlooked.
If you are designing or installing DX HVAC systems you need to know about NZS5149, as by not meeting the standard the consequence could be maximum penalties of $500,000 or up to 2 years’ imprisonment.

Demystifying the Standard

NZS5149 is a safety and environmental standard that primarily deals with refrigerant leakage and more precisely the risk of asphyxiation or fire that can result from any leak. The standard itself is around 200 pages long set out in four sections covering:

  1. Definitions - describing terms, identifying refrigerants, classifying applications, explaining limits and describing mitigation. This is probably where you will spend most of your time trying to understand what is or isn't required for any project.
  2. Design and construction - requirements for piping, components and assembly. For example; pressure testing, tightening torques, inspections methods etc. Needed after you have decided what is required to meet the standard in section 1.
  3. Installation site - specific requirements for applications such as machinery rooms and requirements for mitigation methods such as alarms or ventilation. Hopefully you don't spend too much time in this section, as it means expense.
  4. Operation maintenance and repairs - covers ongoing use of HVAC and mitigation systems to ensure correct performance. Also covers reclaim, disposal handling and storage of various refrigerants.

NZS5149 definitely is a tricky standard, but anyone working with a DX air con or DX industrial plant should be using it regularly.

What Types Of Refrigerants Should I Look Out For?

Many of the old school refrigerants we have been using (like R410A) are class A1 refrigerants. These are non-flammable but somewhat toxic, so under NZS5149 they only have a toxicity limit. However many of the newer refrigerants (think R32, R1234ze, etc.) are A2 class, which means they are both mildly toxic and mildly flammable. These have the double whammy of both a toxicity and a flammability limit - with the stricter of the two being your overall limit. So any flammable refrigerant will likely be harder to make comply with the standard.

However as we're all aware many "old" gasses like R410A have high Global Warming Potential, so are in a heavy phase out period. Going forward you are more likely to have to deal with a "new" gas that has more stringent requirements.

Annexes B1, B2 and B3 in section one of NZS5149 will tell you all the details for the gas you have. These can be applied in to tables A1 and A2 in the same section - which is where you start to see what you are up for and how big the mountain is that you have to climb.

What Types Of Systems And Applications Should I Look Out For?

From a comfort cooling perspective hydronic systems generally have the chiller sited outside in the open air - so even though the volume of refrigerant in them could be large, 99% of the time they won't be a problem for safety under NZS5149.

Most 1:1 split systems usually won't be too much of an issue either, as often the refrigerant charge volumes they have are pretty small. So unless you have a high capacity split serving a small volume space these are unlikely to cause you any issues under NZS5149. The exception is floor console splits as these are mounted close to the ground which causes issues with the flammability calculation. Take care with these.

The real problem child is VRV / VRF systems as these often have a large gas charge with the refrigerant going right into occupied spaces - which can be small. Combine this with the heavy phase down of R410A gas that all large VRV / VRF systems use, and you can see why designers are moving away from these types of systems.

NZS5149 is also why you won't find any large VRV / VRF DX systems being offered in R32. There is simply no way they could comply with the more stringent flammability requirements of R32 - they have enough trouble complying with the lesser toxicity levels of R410A.

Now looking at applications, the standard sets out a sliding scale for requirements based on room occupancy. As you go up the scale the requirements to comply become more and more onerous.

Classifying Applications

Class A - General Occupancy

  • Public access spaces such as schools, restaurants, theatres or supermarkets. Additionally, any place with sleeping facilities such as hotels, houses or retirement facilities
  • Absolute maximum charge kg for a system applies
  • If exceeding the concentration limit generally 2x forms of mitigation are required

Class B - Supervised Occupancy

  • Access somewhat limited, with regular repeat occupants. Most offices and professional spaces will fall in to this category
  • No max charge kg for a system
  • However if concentration limit is exceeded (same limit as class A) sensors and alarms are required

Class C - Authorised Occupancy

  • Restricted access to only a selected few people. Often a locked space such as a store room or restricted area in manufacturing
  • No max charge kg for a system
  • However if concentration limit is exceeded (same limit as class A) sensors and alarms are required

Determine if There is Likely to be a Problem or Not

In comfort cooling the potentially problematic DX systems are currently all either R410A or R32. So for a standard room the rough maximum concentration levels are:

R410A = approx. 1kg per 1m2 of any room served*

R32 = approx. 1kg per 6m2 of any room served*

*note assumes 2.4m floor to ceiling height. Ceiling void cannot be included in room volume.

My Advice? Avoid Mitigation

In my experience mitigation for excessive refrigerant concentration will be expensive, difficult or both. So the first approach you should look at is changing the design to avoid exceeding the maximum concentration levels by:

  • Breaking up larger DX systems in to several smaller ones (although take care as this can add significant costs).
  • Changing to a different type of system. Splits, Hybrid VRF or hydronic systems could all get you out of jail, but of course may require re-work of the design. If doing this be mindful of solving one problem but creating another. For example; splits generally have shorter pipe run maximums which can cause problems for proposed or existing outdoor unit locations.
  • Not directly treating some spaces with A/C. A no-brainer but if the spaces don't have A/C in them then they can't be a problem.
  • Changing the size of the problem spaces. This sounds strange, but if you can increase the size of a space you could solve the problem. Removing a physical barrier like a door, or providing a decent door undercut so that the problem space sums with an adjacent larger one could do the job.

If you can't do any of the above then you are up for mitigation, this can be found in section 3 of NZS5149. Some of the possible methods are:

  • Natural Ventilation
    Both high and low level openings in each room that exceeds the limit are required.
  • Mechanical Ventilation
    Both supply and extract vents in each room that exceeds the limit are required. The vents must be positioned "as low as is practicable", so read this as vents in the ceiling are not acceptable.
  • Safety Shut Off Valves
    Operated by sensor and positioned close to the space in question to prevent the maximum concentration level being exceeded in the event of a leak.
  • Sensors and Alarm System
    Must provide an audible and visual warning and if the application is class A also report to a supervised remote location. Any sensor must be re-calibrated at least annually (some are more frequently). Note: all sensors have a limited service life of between 2 -5 years and so must be regularly replaced.

The Hidden Costs of Mitigation - An Example

A floor in a commercial building that has been separated in to 40x small offices with a VRV system proposed to condition them. Clearly an office is a class B application, so there is no limit on the system charge and no problem right? No, wrong!

In class B, any space that exceeds the maximum concentration limit still needs to have sensors and an alarm system. So if all 40 offices exceed the maximum limit we are up for approximate costs as follows:

Combined 10 Year Life Cost for Alarms = $302,000

As you can see the hidden cost can often be a lot more than changing to a different system type or another design related change.

Combined 10 Year Life Cost for Alarms = $302,000

In Summary

  1. Don't Ignore NZS5149 - the penalties are huge!
  2. Non-flammable gasses comply more easily (but are getting rarer)
  3. Know your space. Is it occupied? What class is it?
  4. Large charge (VRV / VRF) are by far the most problematic
  5. Mitigation is horrendously expensive - avoid it any way you can

R32 Hybrid VRF – The Future-proof Solution

Tuesday 26th of October 2021
Since the New Zealand Government ratified the International Kigali Amendment in 2020, the HVAC industry has had to rethink our use of traditional R410A VRF systems which we have all been comfortable designing and installing in past years.

With these legislative, comfort, safety and environmental pressures on the industry, coupled with the expectations of building owners seeking design and technology which will stand the test of time, Hybrid VRF using R32 refrigerant offers a future-proof solution to cater for the changing needs and expectations of our industry to succeed R410A VRF or VRV systems in the New Zealand market.

Why Choose R32 Hybrid VRF?

All the benefits of VRF with significantly lower GWP

The 2-Pipe Hybrid VRF System offers the same comfort levels normally associated with 4-pipe fan coil systems. In addition, consultants and end users will appreciate the same design flexibility, operational efficiency and advanced control that Mitsubishi Electric traditional VRF is renowned for.

The R32 Hybrid VRF Range brings all of the benefits of VRF air conditioning in an R32 format to deliver a system with a significantly lower Global Warming Potential (GWP) than existing solutions – the shift from R410A to R32 refrigerant realises a 66% reduction in Global Warming Potential.

Combat the rising costs of R410A refrigerant with R32

With the phase-down of HFC gasses particularly effecting R410A, the R32 Hybrid VRF Range provides the obvious answer for those customers looking for a future-proof heating and cooling solution that delivers advanced efficiency with improved corporate social responsibility and minimal environmental impact.

Water instead of refrigerant is at the heart of the indoor units – making it safer for occupants and less expensive to maintain

By using water as the heat medium for the majority of the air conditioning system, Hybrid VRF reduces the overall amount of refrigerant in the system.

Furthermore, with only water between the branch box to the indoor units, Hybrid VRF minimises the need for expensive leak detection leading to significant reductions in on-going maintenance costs in the controlled space that would be needed to comply with AS/NZS 5149 (1-4) 2016.

R32 refrigerant offers low environmental impact without compromising on efficiencies

There is now an expectation that the materials and chemicals used within a building have the least possible impact on the environment and the community.

An R32 Hybrid VRF System can require up to 52% less refrigerant for the same capacity when compared to an equivalent R410A traditional VRF system. R32 Hybrid VRF utilises a single composition refrigerant which has a GWP of only 675 and as a total system it can have an 84% reduction in the carbon dioxide equivalent.

The Synthetic Greenhouse Gas Levy and the Environmental impact with R32 refrigerant is significantly less, meaning that your building is in the best position for being ahead of the curve of change. And if there should be an unexpected leak in the system your costs and impact on the environment involved with re-charging the system will be significantly lower than if you were to install an R410A system. R32 Hybrid VRF is the lowest GWP VRF system in the New Zealand market today.

R32 refrigerant does not just offer a solution to our environmental pressures and phase down targets. From a thermodynamic perspective, R32 offers similar cooling efficiencies as well as improved heating efficiencies when compared to R410A.

Choosing R32 Hybrid VRF is the Smart Investment

Hybrid VRF futureproofs your investment ensuring your air-conditioning plant has the expected longevity, and gives you the assurance that the chemical refrigerant will not be priced out of the market by the means of the government imposed Emissions Trading Scheme on Synthetic Greenhouse Gasses and the International Kigali Amendment agreement.

Hybrid VRF, with its ever expanding product range and world leading technology, is a revolutionary product that is truly disrupting the HVAC industry.

Extended R32 Hybrid VRF Indoor Range

Mitsubishi Electric has made significant strides in research and development of Hybrid VRF technology. In 2014, when Hybrid VRF was first introduced to the New Zealand Market by Black Diamond Technologies there were only 16 indoor units to choose from.

Fast forward to 2021 and there are now 53 indoor models on offer, including the introduction of larger capacity PKFY Wall Mounted Units, a new PEFY Ceiling Concealed High Static Pressure Range and new sizes within both the PLFY 4-Way Airflow and Compact Cassette Ranges.

Introducing the New Plasma Quad Connect Advanced Air Filtration Accessory

Monday 18th of October 2021
We spend up to 80% of our time inside. As such, good indoor air quality is paramount to our well-being. So how can home owners have the peace of mind they are breathing cleaner, healthier air all year round?

Introducing the Plasma Quad Connect – a new high wall accessory, featuring high-performance two stage plasma technology. The advanced filtration system works to clean away smells, dust, mould and other common household allergens, making it an ideal addition for asthma and allergy sufferers.

How Polluted is the Air Inside Your Home?

You may be surprised how contaminated indoor air can actually be. You might not be able to see it – but it is there! Every time you open your doors or windows, external pollutants such as pollen, dust and other allergens enter the home. But did you know oil and fat particles from cooking all release microscopic particles into the air too?

Dust and pet dander (dead skin flakes), mould build-up and mildew spores triggered by dampness can further increase concentrations of pollutants. There is substantial evidence to support the claim that breathing Particulate Matter (PM) is harmful to human health, particularly smaller fractions such as PM10 and PM5.

Cleaner, Healthier Air with 2 Stage Plasma Filter

The Plasma Quad Connect is designed to work like an electrical curtain, using an advanced two-stage process which first makes plasma that breaks down air pollutants and then creates an electrical discharge that neutralises even microscopic particles in the air.

In fact, it can even capture particles as small as PM2.5, that's 20 times smaller than the width of a human hair! Unseen to the human eye, these microscopic particles can easily penetrate deep into our lungs and even our bloodstream.

The result? A more healthy and cleaner living environment that can be enjoyed year-round.

Highly Effective Filtration

Independent test results confirm that the Plasma Quad Connect Filtration System achieves extremely high reduction results in the removal of allergen, mould, bacteria and virus particles in the room. This provides the ultimate peace of mind and ensures a healthier and cleaner living environment.

Connect to New Installs or as a Retrofit

Designed to be installed directly above high wall units, the Plasma Quad Connect is compatible with the following High Wall Systems.

  • EcoCore GL Series
  • EcoCore AP Series, Classic AP Series and AP Mini
  • Designer EF Series
  • Large Capacity AS90
  • Large Capacity PKA-M
  • GE Series

This slimline, advanced air filtration accessory provides a value-added sales opportunity when paired with compatible high-wall units.

Plasma Quad Filtration is built-in as a standard feature in the Black Diamond LN Series.

Not requiring installation in the attic, the new Vertical Lossnay Range resolves the issue of no roof space, offering an alternative installation solution. Now more homes can have a Lossnay Fresh Air Heat Recovery System, regardless of their design and installation challenges.

Small Enough to Fit in a Cupboard

The Vertical Lossnay Range is designed specifically for the New Zealand housing market and makes energy efficient, super-quiet ventilation accessible to even more homes.

With a small and vertical upright design, the Lossnay Ventilation System is not limited to an in-roof installation and its compact footprint allows it to be placed in the garage or a cupboard in the kitchen. Now whole home ventilation can be installed and integrated in the overall building design without limitations.

Fresh Filtered Air with Heat Recovery Maximising Efficiencies

Ventilating our indoor spaces is more important than ever, but we also need to be as energy efficient as possible. The new Vertical Lossnay will deliver fresh filtered air whilst recovering energy to minimise waste.

In fact, Lossnay’s unique heat recovery technology recovers up to 85% of the heat energy from the outgoing stale air which is then used to pre-warm (or pre-cool) incoming fresh air. This means any heating or cooling appliance does not have to work as hard to reach the desired room temperature – providing savings on your energy bill and maintaining a healthy home environment.

Advanced Filtration for Better Health and Wellbeing

The quality of indoor air is an important factor for health and wellbeing and the new Vertical Lossnay Range ensures there is a constant flow of fresh air into our homes, and that potentially harmful pollutants and chemicals are being removed at the same time.

The new residential range comes with optional NOx (nitrogen oxide) and Particulate Matter Filtration, with a unique third filter pocket which can be used for additional filtration of NOx emissions.

This means that homes in even the most polluted environments can be supplied with clean, healthy air.

Automatic Summer Bypass

A built-in Automatic Summer Bypass also allows the units to bring in fresh air from outside without transferring heat, in order to reduce the risk of overheating.

This provides the ideal solution for cooling down a dwelling that may have overheated during the day once the outside temperature has dropped in the evening.

Using onboard temperature sensors, the unit can automatically enter Bypass Mode when it detects the space is hotter than desired and the outside air is cool enough.

Easy to Use Control

A built-in LCD controller allows for easy control and commissioning of the unit, and offers a clear display showing normal, boost, and purge modes. Up to four speed settings can be commissioned digitally to ensure constant and accurate settings.

QAHV – The Future of Hot Water Heating

Tuesday 3rd of August 2021
When selecting hot water systems for commercial and industrial applications, having a reliable system that will meet today’s needs now and those of the future is important. Mitsubishi Electric have developed QAHV; the latest innovation in a comprehensive line-up of Hot Water Heat Pump products. Specifically designed to produce high temperature potable hot water up to 90°C, the QAHV is suitable for commercial and industrial projects.

Using natural CO2 as the refrigerant, the QAHV provides one of the lowest environmental impacts when generating potable hot water. It is engineered to perform well in harsh conditions and climates, and of course being an inverter heat pump it does so extremely efficiently. By adopting Mitsubishi Electric's unique technology, the QAHV ensures highly reliable performance as well as high heating capacity even at low outdoor temperatures.

Why Invest in Environmentally-Friendly Hot Water Solutions?

The industry is shifting. The Government has banned new coal boilers from the end of 2021 and businesses will need to phase out existing ones by 2037. Simultaneously the Government is providing $70M to support and incentivise businesses to switch away from boilers to cleaner, greener options for hot water production. While many may turn to natural gas, the Climate Change Commission is proposing no new gas connections to buildings from 2025 and a steep phase out of existing gas boilers from 2035 onwards.

Currently gas is used to produce hot water in the majority of commercial buildings in New Zealand, and while gas is an attractive option due to its compact footprint, it is a very high carbon emitter and isn’t particularly efficient, even if the building is using a modern condenser boiler – not to mention the potential risk to occupants if a leak occurs.

With the future of traditional forms of hot water heating uncertain, it is clear that those within the industry, engineers, designers, installers or owners, must move to new solutions for water heating in commercial buildings – and the move needs to start now.

CO2 Refrigerant is the Key to Future-Proofing Hot Water

The growing emphasis on global warming mitigation has stimulated interest in a new generation of low-GWP refrigerants, many of the new refrigerants being created feature GWP’s around 500 to 600 or even less. But nothing can compete with CO2 and its GWP of 1 – it provides the reference point for environmental impact that all other refrigerants are measured against.

The QAHV series utilises CO2 as it is an environmentally-friendly, safe and natural refrigerant with zero Ozone Depletion Potential (ODP) and a Global Warming Potential (GWP) of 1.

There is no greener alternative currently available in New Zealand.

Patented Mitsubishi Electric Technology increases Energy Savings

The Mitsubishi Electric QAHV System utilises a twisted and spiral gas cooler. This patented technology enhances energy efficiency while delivering high temperature hot water.

Using twisted pipes as water pipes and running the refrigerant pipes along their grooves helps to increase the heat-conductive area. The continuous spiral groove design accelerates the turbulence effect of water and helps to reduce pressure loss within the heat exchanger, enhancing efficiency.

Equipped with the latest inverter scroll compressor, QAHV offers unparalleled efficiency when compared to fixed speed systems - boasting an impressive COP of 3.88*.

*Under normal heating conditions at outdoor temp: 16°CDB / 12°CWB, inlet water temp 17°C, outlet water temp 65°C.

Superior Heating Performance even at Low Temperatures

As ambient temperatures drop, so too does the capacity of heat pumps. However, the QAHV is able to provide its full heating capacity of 40kW even at ambient temperatures as low as -3°C. Furthermore, the unit operates to supply 90°C hot water in ambient temperatures as low as -25°C. This superior level of performance is achieved using Mitsubishi Electric’s industry-first Flash Injection Circuit which provides the optimum amount of refrigerant to the system via a compressor through a specially designed injection port. This ensures a highly stable operation that at the same time, meets the guidelines for Legionella.

Better Security of Hot Water Supply and More Lettable Space

As a single pass high temperature lift machine, QAHV works best with a high water temperature difference and delivers 10l/min or more of full temperature usable hot water in real time. This directly reduces the amount of storage required to meet the peak demands, and gives quicker recovery. Ideal for commercial uses where hot water demand is high, such as gyms, hotels, motels, aged care facilities and hospitals.

Optional Mitsubishi Electric “BS” Salt Corrosion Protection System Available

To help extend the life of the QAHV outdoor unit when located within highly corrosive environments, the optional Mitsubishi Electric “BS” Salt Corrosion Protection System can be applied during the outdoor units manufacturing process to ensure all components are 100% protected before the outdoor unit is assembled.

QAHV-N560YA-HPB Key Features:

  • Rated Heating Capacity of 40kW
  • High efficiency (Achieved COP 3.88*)
  • Supplies high temperature hot water of up to 90°C
  • Operable even at low outdoor temperature of -25°C
  • Utilises natural CO2 refrigerant which has zero Ozone Depletion Potential (ODP) and has a Global Warming Potential (GWP) of 1
  • Uses a unique twisted and spiral gas cooler to enhance energy efficiency
  • Compact dimensions, minimising plant space

* Under normal heating conditions at outdoor temp:16°CDB/12°CWB, inlet water temp 17°C, outlet water temp 65°C

While its environmental-friendliness is QAHV’s leading strength and the key to future-proofing from climate change and subsequent government legislation and regulation, its superior performance is what really makes QAHV a smart investment.

New Lossnay Sensible Heat Recovery Ventilation

Monday 2nd of August 2021
Mitsubishi Electric has extended the Lossnay LGH Energy Recovery Ventilation Range to now include Sensible Heat Recovery Only models. The new range features a new non-permeable Lossnay Core that is specifically designed to recover sensible heat and remove moisture at the same time.

The newest addition to the Lossnay Range introduces fresh filtered air and thanks to the new core can now draw stale air out from areas with high humidity such as bathrooms, kitchens and laundries as well as commercial applications such as gyms, healthcare centres, schools and offices.

Furthermore, the range features easier installation, quiet operation, high energy efficiency and optimised control.

Highly Efficient Sensible Heat Recovery

This system is designed to transfer sensible heat only (the heat you can feel as temperature changes) and maximises heat recovery from the stale outgoing air. In addition, due to the non-permeable core it also removes moisture in high humidity areas at the same time.

The available energy is transferred and re-used to pre-warm or pre-cool the incoming fresh air, maximising energy efficiencies. In doing so, moisture build-up is minimised while healthy humidity levels are maintained and managed for occupants throughout the entire building.

It is important to note that it does not recover latent heat, which is the additional heat contained in the airborne moisture in the air. The Sensible Lossnay System uses a non-permeable core so moisture cannot be absorbed by the core. For this reason, the system has a drain connection that is piped to waste.

Whole Building Ventilation Even From Humid Areas

Now you can bring fresh filtered air in and draw stale air out, even from high moisture areas - with the added benefit of Sensible Heat Recovery maximising energy efficiencies. The non-permeable Lossnay Core enables the system to ventilate all areas, including those with high humidity such as bathrooms, kitchens, gyms and health care centres.

Maintenance is made easier with the fully removable and washable core. The Sensible Lossnay design also includes a full drain pan which avoids mould and odour inside the unit by ensuring moisture is drained throughout all seasons.

Easy, Flexible and Lightweight Installation

The unit features one drain pipe terminal allowing for quicker and lower cost installation. Trap piping is not required as the new Sensible Lossnay unit features backflow prevention and an internal inclined drain pan, which not only helps with installation, but also reduces the risk of mould and odour.

Flexible ductwork and a swivel drain pipe mean installation can be incorporated into building designs with the ability to avoid obstructions and be set out of the way against walls.

Furthermore, the chassis of the Sensible Lossnay Range is lightweight, making installation easy and safe.

Low Noise Operation

With models starting from 18dBA*, the Sensible Lossnay System includes a unique, specifically designed fan that optimises the balance between airflow and static pressure to minimise noise levels.

The new range also has an optional Silencer Duct that can reduce noise further when a quiet solution is paramount.

Installation improvements have been made to the pipe position and longer adjuster bolts are at the base of the cylinder.

Hot water heat pumps are better for the environment

Did you know traditional electric hot water heaters produce up to three times the amount of greenhouse gas compared to a low emission alternative such as a hot water heat pump?

Instant gas hot water systems contribute to even greater greenhouse gas emissions. By producing a staggering seven times more emissions compared to hot water heat pump technology.*1, this makes water heating one of the largest single sources of greenhouse gas emissions from the average Kiwi home. This is evident to such an extent that EECA (Energy Efficiency & Conservation Authority) has identified heat pumps as playing a key role in significantly reducing costs and greenhouse emissions from energy use.

An estimated 67% of New Zealand homes use a traditional electric hot water system*2. Substituting existing, less efficient technologies with their more efficient counterparts, such as a hot water heat pump, can contribute to a significant reduction in overall greenhouse emissions.

If you are looking for a super energy-efficient water heating solution that is also kind to the environment, Mitsubishi Electric Ecodan Hot Water Heat Pumps are the natural solution.

What’s the secret behind the Lossnay VL-220 Whole Home Energy Recovery Ventilation System?

Monday 22nd of February 2021
Lossnay, which originates from the Japanese word “Loss-Nai” meaning “no loss”, is an advanced fresh air heat recovery ventilation system from Mitsubishi Electric. Lossnay captures and filters fresh outdoor air (as opposed to attic air) to replace indoor stale air. As a result, an all-round healthier, drier and warmer home is created.

Unlike other more basic positive pressure ventilation systems, Lossnay uses balanced pressure to effectively move air into the room at the same rate as the outgoing stale air. Furthermore, super-efficient heat recovery is possible thanks to the patented Diamond Core Heat Exchanger that is at the heart of the VL-220 system.

Achieve maximum heat recovery from outgoing stale air and from high moisture areas

The patented highly efficient Diamond Core in the VL-220 is designed to maximise heat recovery from the stale outgoing air with temperature exchange efficiency of up to 86%.

This recovered energy is then used to pre-warm or pre-cool the incoming filtered fresh air. This means that your existing heating system is not required to work as hard to bring a room up to the desired temperature, saving energy costs.

In addition, the VL-220 Diamond Core is designed with a unique and specially treated non-permeable resin membrane which allows the system to also effectively extract air from high humidity areas such as bathrooms, toilets and kitchens. As these rooms tend to be higher in temperature, the ability to recover more heat is enhanced to maximise overall efficiencies.

Comfort and healthy home living

With Lossnay’s advanced patented technology, your house is ventilated with fresher, filtered and cleaner pre-warmed (or cooled) air at the same time. By drawing in fresh outdoor air, indoor air quality levels are improved as high levels of CO2, odours and other pollutants are removed from your home.

This filtered fresh air improves the air quality to create comfortable, healthy living for occupants all year-round. As such, Lossnay is ideal for allergy and asthma sufferers.

Effective home ventilation is more important than ever

Recently, there has been greater consumer awareness surrounding the importance of indoor air quality. With more airtight homes being built to meet higher insulation standards, the need for adequate ventilation has become a priority for many households.

A quality ventilation system introduces fresh, filtered air which also helps to reduce moisture by directly removing stale air that causes condensation via the Lossnay Core.

Lossnay’s standard washable filters ensure the system works at its best for longer

The Mitsubishi Electric Lossnay VL-220 Whole Home Energy Recovery Ventilation System is supplied with two standard G3 Filters (one supply and one exhaust) that can be washed up to four times.

This not only keeps the unit in optimal working condition but creates a more comfortable environment for the occupants.

The new Classic MXZ Multi Room outdoor lineup now features more environmentally-friendly R32 refrigerant

Monday 1st of February 2021
We are pleased to announce our Classic Multi Room Heat Pump Range is now available in a full range of R32 outdoor models. The move to R32 refrigerant signals our commitment to minimising the impact on the environment whilst maximising energy efficiencies.

Extended pipe lengths

In addition to incorporating more environmentally-friendly R32 refrigerant, the Classic Multi Series also features extended pipe lengths of up to 25m per indoor unit with no more than 15m in height (additional refrigerant may be required). The total pipe length may extend up to 80m.

Whole home heating or cooling

Over the years, the lounge was the most common place to find a heat pump in the home, but times have changed. Today, as households enjoy the year-round comfort of heating and cooling in their living room, more homeowners are installing heat pumps in other rooms such as bedrooms, home offices and hallways.

The futureproof solution – add indoor units when your family grows

Changes like working from home and welcoming a new addition to the family are all key drivers where heating or cooling just in the lounge is not going to be enough to keep the whole family comfortable all year round.

Thinking ahead and installing a Multi Room System, however, is an investment that you won’t regret. The ability to connect one or two indoor units initially and add more later, gives you the flexibility to expand in the future.

One outdoor unit keeps the exterior clutter-free

While a standard heat pump system requires a separate outdoor unit for every indoor unit inside the home, a Multi Room Heat Pump System only requires one outdoor unit. As such it reduces exterior clutter to not only enhance your home’s exterior but makes them ideal for areas where space is at a premium. With properties getting smaller and high density living more and more prevalent, having just one outdoor is going to be a real selling point in the future.

Style for each and every room

With a Multi Room Heat Pump System, you have the flexibility to choose the perfect indoor heat pump for each room. Whether it’s a small capacity whisper quiet high wall for the bedroom, a compact floor console for the office or a discreet ducted model for the lounge, there is a style and capacity to fit any room – no matter the size or interior aesthetic.

Now you can combine a Multi Room Air Conditioning System with hot water heating!

Thursday 21st of January 2021
The next-generation in hot water heating and whole home comfort is here. We are pleased to announce that the Ecodan Range has been expanded to enable seamless integration with a Multi Room Air Conditioning System. This means you can now experience total home comfort including energy efficient cooling in summer and hot water heating all year-round using a single outdoor unit.

Three outdoor capacities to choose from

The range is available in three sizes including a 14kW, 16kW and 18kW model. This much-anticipated product uses the Twin-Fan PUMY-P outdoor unit with a specially designed branch box. This connects to all our indoor units from our existing Multi Room Range.

Uses only one outdoor unit to minimise external clutter

Because the Ecodan System is able to join to that same branch box, domestic hot water, underfloor heating and radiators or a combination of all can be part of the same Multi Room System.

As a result, outdoor space is maximised as there are no additional big bulky outdoor units to worry about.

What are the key components?

The outdoor unit

The system uses our existing Twin-Fan PUMY-P outdoor unit.

The branch box

The PUMY-P outdoor unit is connected up with a specially designed branch box, with 5-port and 3-port branch boxes available which can be combined to allow connection of up to eight indoor units. Up to two branch boxes can be connected to the PUMY-P outdoor, enabling a wide range of configurations.

The indoor air conditioning units

Just like a traditional Multi Room System, any indoor unit from the Multi Room Range can be connected to the PUMY-P outdoor. This includes high walls, floor consoles, ceiling mounted and even ducted concealed units. This means the PUMY-P System is able to provide energy efficient air conditioning or heating of multiple rooms.

Furthermore, all units are run in either Heating Mode or Cooling Mode, with individual temperature control for each room.

The Ecodan Hot Water System

Either an Ecodan Hydrobox or Ecodan Packaged Water Cylinder System can be connected to the branch box. Designed with flexibility in mind, the system allows for various combinations to suit different applications including adding underfloor heating and radiators.

The illustration to the right shows a combined Mitsubishi Electric Multi Room with Hot Water System that features underfloor heating in the winter season and air-to-air cooling for the summer, whilst producing domestic hot water all year round.

How does it cool in summer and provide hot water?

To ensure the whole system is working as efficiently as possible, hot water demand is always prioritised. This means when the air conditioning indoor units are turned on in cooling and there is a hot water demand, hot water supply will override the cooling function of the air conditioners.

Prioritising hot water will continue until set temperature is reached. To mitigate this, it is important to set the time scheduler accordingly so water heating happens when cooling is not required at the same time.

For example, you can simply set the heat up time for when you are out at work or early hours of morning via the remote controller which can be located anywhere in the home.

Summer 2-in1 operation

In summer, air-to-air (ATA) cooling and domestic hot water (DHW) are utilised. Keep your room comfortable with ATA cooling during high temperature daytime. Heat pump operates to heat up water stored in DHW cylinder when ATA is not operated. The hot water can be utilised for shower and washing dishes during daytime.

The evolution in total home comfort is here

The ability to now combine a Multi Room Air Conditioning System with hot water heating is the ultimate in year-round, total whole home comfort.

The new Mitsubishi Electric Climaveneta INTEGRA i-FX-Q2-G05 4 Pipe Multifunctional Heat Pump Chiller with low GWP refrigerant R513A

Monday 14th of September 2020
The Mitsubishi Electric Climaveneta INTEGRA Range has been extended with the addition of the new i-FX-Q2-G05 multipurpose outdoor unit.

Utilising the more environmentally-friendly R513A refrigerant, the system simultaneously produces heating and chilled water using two completely independent hydronic circuits.

These heat pump chillers now exceed the minimum seasonal efficiency tier imposed by the ErP (Energy-related Products) Directive 2009/125/EC, effective in Europe from January 1st 2021.

More environmentally-friendly R513A has a GWP that is 56% lower than R134A refrigerant

The range offers high annual efficiencies achieved through inverter technology and uses low GWP R513A refrigerant.

With a GWP of only 631, R513A refrigerant has a significantly smaller carbon footprint compared to traditional systems utilising R134A.

Furthermore, the refrigerant is also non-toxic and non-flammable (Class A1 according to ISO 817).

This makes it the best choice for projects that require an eco-sustainable energy efficient solution.

The move to R513A is in line with a worldwide phasedown of the production and consumption of hydrofluorocarbons (HFC), moving away from traditional HFC refrigerants such as R134A to more environmentally-friendly, energy efficient blended refrigerants.

Next-generation VSD Screw Compressors and EC Fans maximise energy efficiency

Thanks to the use of full inverter screw compressor and EC fans, the unit guarantees optimal energy efficiency for the system.

This high efficiency translates into reduced energy consumption throughout the year for any mode of operation, no matter what the outdoor conditions are.

Full Inverter Technology ensures greater efficiencies at part load

In a traditional comfort application, an HVAC plant works at maximum power only for a limited number of hours per year. Therefore, it operates at part load conditions most of the time.

The new i-FX-Q2-G05 multipurpose units use the latest variable-speed technology in all the main components. With their accurate design, these models achieve greater efficiencies compared to similar fixed-speed units, with any combination of heating/cooling load in any season.

As these models incorporate variable-speed screw compressors, the system is able to effectively achieve any combination of load required by the HVAC plant.

Furthermore, it features superior Total Efficiency Ratio (TER) efficiencies of up to 19% higher when compared to units with fixed-speed compressors.

Improved seasonal efficiencies are achievable with variable water flow control

These higher efficiencies have been obtained by calculating both SCOP and SEER efficiency parameters with the variable water flow calculation method. As such, this takes full advantage of the variable speed technology of the i-FX-Q2-G05.

To allow the unit to manage the variable water flow, the standard configuration of the hydronic modules and flow controls has slightly changed. Now, the unit is able to control the activation and the speed (via a 0-10V signal) of an external variable speed pump both on the evaporator and on the condenser side.

Quiet operation for ultimate comfort

The inverter's ability to continuously change the compressor speed provides reduced sound emissions, especially at part load to maximise acoustic comfort.

The i-FX-Q2-G05 Range is available in three noise options:

  • CA for Class A efficiency (as standard)
  • SL-CA for super low noise with Class A efficiency
  • XL-CA for extra low noise with Class A efficiency

Reliable operation all year-round

Inverter technology provides the added advantage of no in-rush current.

Sudden power surges and variations in the starting torque are minimised. Additionally, possible disturbances to the power grid are eliminated. As a result, lowering stress on electrical components and improving the reliability of the system.

The frequency converters selected are characterised by a Displacement Power Factor between 0.97 and 0.99. As a result, the Unit Power Factor under nominal operating conditions is always higher than that of a similar unit without inverter technology.

The W3000TE Controller and KIPlink Wi-Fi Interface enables total plant control from anywhere

The i-FX-Q2-G05 utilises W3000TE Software, which is characterised by advanced functions and algorithms for optimum control. As such, it ensures a rapid adaptive response to the different dynamics of the plant, in all operating conditions.

Access to the controller is through the innovative KIPlink Interface. With more versatility than the traditional keyboard concept, users can operate the unit directly from their smartphone, tablet, or laptop.

Lossnay Single Room Ventilation with Energy Recovery is now available with an in-ceiling ducted solution

Tuesday 7th of July 2020
Mitsubishi Electric Lossnay Single Room Ventilation is designed to provide cost-effective energy recovery ventilation to one specific area in the home. In addition to the wall-mounteed VL100 Single Room Ventilation System, we have extended the range to now also include a ducted model that is the perfect unobtrusive in-ceiling solution.

The benefit of fresh air

Stale air with higher levels of CO2 is a common problem not only in schools and offices but also in homes where structures are becoming more and more airtight due to more stringent building regulations.

High levels of CO2 can affect concentration and learning as well as overall wellbeing and productivity. Furthermore, the lack of natural ventilation in airtight spaces can lead to the build-up of moisture-laden stale air. This is the perfect breeding ground for mould that can trigger allergy or respiratory problems.

The option of leaving doors and windows open to allow fresh air to enter is not always desirable or practical, with potential security risks and greater exposure to outdoor noise.

This is where a fresh air ventilation system like Lossnay can make a real difference.

Balanced pressure energy recovery ventilation

The Lossnay VL100 Range includes a ducted model that is the perfect unobtrusive in-ceiling solution. For applications without adequate roof space, there is a ductless unit purpose-built to accommodate a simple back-to-back wall hung installation.

The balanced pressure ventilation system captures and filters fresh outdoor air (as opposed to stale attic air) to replace indoor stale air for an all-round healthier, drier and warmer room.

The Lossnay Core

The Lossnay Core recovers energy from the extracted stale air, to pre-warm or pre-cool the incoming air.

As a result, an existing heating appliance in the room does not have to work as hard to reach desired temperatures, maximising energy efficiency and reducing your energy bill.

Single Room VL100 Ducted Ceiling Mount Fresh Air Energy Recovery Ventilation

This ducted model is specifically designed to provide energy efficient ventilation to ensure an individual room has a constant supply of filtered fresh air whilst minimising moisture build-up. Furthermore, incoming air is pre-warmed (or pre-cooled) so your existing heating appliance does not need to work as hard to reach desired temperatures.

Key specifications of the VL100 Ducted

  • Up to 64% heat exchange efficiency
  • Low height 204mm
  • 100mm duct diameter
  • Lightweight and compact
  • Low noise operation from 25dB on low fan speed
  • Filter replacement notification
  • Air intake can be installed away from the unit in the most convenient location
  • Ideal for residential or small commercial applications with ceiling void or roof space

Single Room VL100 Wall Mount Fresh Air Energy Recovery Ventilation

This wall mounted unit provides an effective balanced pressure ventilation solution for a specific area up to 90m2*. Lossnay recovers energy from the air being transferred to pre-warm (or pre-cool) the fresh air drawn into the room. As a result, moisture build-up is minimised and a warmer, drier and healthier indoor environment can be maintained all year round.

Because this model is ductless in design, it is ideal for applications where there is no roof space to accommodate the heat exchanger and duct work.

Key specifications of the VL100 Wall Mount

  • Up to 80% heat exchange efficiency
  • Simple installation by drilling two 75mm diameter installation holes
  • Low noise operation from 25dB on low fan speed
  • Easy to clean filters
  • Ideal for residential or small commercial applications where there is no roof space


Energy recovery ventilation works all year round

In winter a traditional ventilator captures fresh air at the cold outside temperature. Lossnay Ventilation preheats the outside air before bringing the fresh, filtered air inside.

In summer a traditional ventilator captures fresh air at the hot outside temperature. Lossnay Ventilation lowers the outside air temperature before bringing the fresh, filtered air inside.

Many underfloor heating (UFH) installations involve wet cement poured over the UFH pipework and then has to set. The tricky part is the dry time where it’s pivotal to prevent any cracking or unwanted movement, especially when another floor layer is added on top of the dried concrete.

Ecodan solves this by using Floor Dry Up Mode which lets you set step increment by as little as 1°C for 1 to 7 days to reach the desired UFH temperature. This method can be used to dry the concrete out and remain at target temperature whilst new flooring is added.

The Dry Up Mode can be programmed to suit the concrete type and installer preference for the build, making this one of the most practical features for UFH applications on the market.

The control is in your hands with energy monitoring and system analysis

Ecodan controllers have several ways to analyse the system again to help the installer and homeowner / tenant.

Easy diagnosis with SD Card Analysis

The SD Card System Analysis will start recording the system including:

  • flow temperature
  • setpoint
  • outdoor temperature
  • flow rate
  • pump speed
  • compressor frequency
The data provides the installer with the opportunity to diagnose the system after installation and make fine-tuning if necessary to meet the customers’ requirements.

Home automation system control

Ecodan can be controlled by connecting a MelcoBEMS Mini Interface to the indoor control board. MelcoBEMS Mini is a MODBUS interface that can enable the hot water and heating solution to be controlled and monitored by a high-end home automation or building management system in a commercial environment.

Evaluate energy usage at a glance with Energy Monitoring

This setting on the remote controller displays the energy consumed and delivered so the end-user can understand when the most energy is used and can check the consumption is low; especially if there is a high-cost electricity bill that month. We can take it one step further by adding smart energy meters to accurately monitor the electricity consumed using the Smart Grid Ready function. In addition to this, the user can set up auto recovery after power failure so the Ecodan System turns back on with all its settings as it was left and will continue to monitor energy use.

Ecodan is the next-generation in hot water and space heating

Ecodan Hot Water Heat Pump Systems are the most capable systems on the market, delivering functional and practical capability for both the installer and user. In this day and age with demands for quick, cost-effective application coupled with ongoing benefits, the Ecodan System is leagues ahead.

Hybrid VRF – The advantage of water

Friday 19th of June 2020
As BDT and Mitsubishi Electric grow into the new era of sustainability and environmental awareness, one thing has become very clear; systems comprising of water will play a large part in the transference of heat in the commercial HVAC market globally in the coming years.

Hybrid VRF (HVRF) bridges the gap between VRF / VRV solutions and heat recovery chiller plant, offering an alternative to common hydronic systems while still retaining the inherent benefits associated to the water-based options.

The HVAC market has been using water as a refrigeration and heating medium for many years, with chilled water being a safe, reliable refrigerant with a number of beneficial characteristics. Chillers, hot water heat pumps and 4 or even 6 pipe hydronic solutions have been utilised in large commercial buildings for many decades.

Simultaneous heating and cooling with full heat recovery

Heat recovery chiller systems are considered the crème-de-la-crème of HVAC solutions, incorporating the inherent efficiencies only possible through heat recovery with the comfort and security of water as the medium being circulated into occupied spaces. However, these have been a largely uneconomical option for small to medium scale applications.

The economic hydronic heat recovery solution

The Hybrid VRF (HVRF) product category bridges the gap between VRF / VRV solutions and heat recovery chiller plant, offering an alternative to common hydronic systems while still retaining the inherent benefits associated to the water-based options.

Hybrid VRF places itself in the market as an economic hydronic heat recovery solution which can be applied from high-end residential homes and the small commercial market right through to a large scale modular solution.

All the benefits of VRF with significantly lower global warming potential

With the adoption of global initiatives to reduce greenhouse gases and local legislative requirements with regards to occupant safety, HVRF provides design engineers and mechanical contractors the mitigation of risk associated with circulating refrigerants into occupied spaces. Furthermore it also reduces the potential global warming impact the larger refrigerant volume imparts; offering a saving on associated costs.

Hybrid VRF is the new VRF standard in New Zealand for both large and small applications

In the New Zealand market alone, BDT have seen a huge uptake of Hybrid VRF in the market. With over 5MW of heating capacity ordered to date across 42 projects Hybrid VRF applications are growing.

The largest Hybrid VRF project in the New Zealand market currently in construction incorporates 512kW cooling and 575kW of heating across 11 HVRF systems and is due for completion in FY21. This scale of project is a prime example of situations where a hydronic solution could have been applied however the HVRF alterative offered ease of construction, cost savings, modularity and redundancy reduction in the case of a mechanical failure.

Of course on the other hand, smaller systems can offer the benefits of hydronic architecture to projects that may be of a scale in which it is not economic to outlay the capital cost associated to a 4 pipe solution.

One such case is PGG Wrightsons Seeds wherein the developer Ngai Tahu was seeking to design a water-based system for their new building in Lincoln. The prerequisite was for a hydronic, water-based design for occupant comfort and safety reasons. In this instance, Hybrid VRF was the nominated solution to meet the hydronic requirements while offering the installation advantages of a modular VRF system.

HVRF key benefits

Minimise the need for leak detection systems

In commercial buildings, additional leak detection systems specific to air conditioning are often installed to safeguard occupants due to increasing safety regulations. This affects hotels in particular, where air conditioners are installed in the room space and occupant safety is critical.

A leak detection system is designed to trigger an alarm if refrigerant was to leak into the room space and initiate an evacuation of the area to try and prevent harm to the occupants. These systems can be expensive and add to the cost of design, build and maintenance.

Flexible design and modularity allow for a manageable phased installation

The small footprint and modular design means building owners can now take advantage of a manageable phased installation.

Regulated phase down of CO2 emissions

GWP is a measure of the global warming potential as compared to CO2 which has a unitary GWP of 1. R32 refrigerant is zero ozone depleting (ODP)and has a GWP 66% less than R410A. For example R410A will hold 2,088 times more heat when released in the upper atmosphere than the equivalent amount of CO2 would.

R32 refrigerant is being adopted by Mitsubishi Electric as an important step in the process towards the ultimate goal of a zero ODP, zero GWP, efficient, safe, and non-toxic refrigerant.

New City Multi R32 Hybrid VRF Delivers a System with a GWP 66% Less Than Existing R410A VRF Solutions.

Thursday 28th of May 2020
With the pressure on R410A refrigerant increasing, Mitsubishi Electric’s commitment to reducing the environmental impact of air conditioning has seen the introduction of New Zealand’s first VRF (Variable Refrigerant Flow) solution that has adopted R32 refrigerant.

R32 Hybrid VRF is the world’s only low GWP 2-pipe hydronic heat recovery system

Mitsubishi Electric has long been a leader in the world of air conditioning and the world’s first R32 Hybrid VRF Product Range again puts the company at the forefront of the industry.

Hybrid VRF utilises low GWP refrigerant R32, providing a real solution that delivers high operational efficiency whilst minimising the Global Warming Potential of the refrigerants used within these systems.

Having already introduced R32 refrigerant across its residential M-Series and commercial P-Series Split System Ranges, it was only a matter of time that Mitsubishi Electric tackled the VRF / VRV market with a solution that also adopted a low GWP refrigerant like R32.

The Mitsubishi Electric R32 VRF Solution is an evolution of Mitsubishi Electric’s Hybrid VRF System. First introduced in 2014, this unique 2-Pipe Hybrid VRF System combines VRF and chiller technologies using water throughout the majority of the pipework to efficiently transfer simultaneous heating and cooling to different rooms.

Water instead of refrigerant is at the heart of the indoor units

By using water as the heat transfer medium for the majority of the air conditioning system, Hybrid VRF reduces the overall amount of refrigerant in the system. Furthermore, with only water connecting the branch box to the indoor units, Hybrid VRF minimises the need for expensive leak detection leading to significant reductions in on-going maintenance costs in the controlled space that would be needed to comply with AS/NZS 5149 (1-4) 2016.

All the benefits of VRF with significantly lower Global Warming Potential

The 2-Pipe Hybrid VRF System offers the same comfort levels normally associated with 4-pipe fan coil systems. In addition, consultants and end-users will appreciate the same design flexibility, operational efficiency and advanced control that Mitsubishi Electric traditional VRF is renowned for.

In short, the addition of R32 to the Hybrid VRF Range brings all of the benefits of VRF air conditioning in R32 format to deliver a system with a significantly lower Global Warming Potential (GWP) than existing solutions. In fact, the shift from R410A to R32 refrigerant realises a massive 66% reduction in Global Warming Potential.

The complete solution for today’s modern buildings

Over the last 5 years, Hybrid VRF applications have already enjoyed significant growth in New Zealand. These systems have been successfully incorporated in a variety of designs ranging from offices, hotels, retirement villages, education facilities, medical centres and much more.

Combat the rising costs of R410A refrigerant

With the phase-down of HFC gasses, particularly effecting R410A from next year, the introduction of the new R32 Hybrid VRF Range now provides the obvious answer for those customers looking for a future-proof heating and cooling solution that delivers advanced efficiency with improved corporate social responsibility and minimal environmental impact.

R32 Hybrid VRF is the new VRF standard

R32 Hybrid VRF is the new era of VRF in the market. Mitsubishi Electric has strived to design a system which not only meets the legislative requirements being imposed on the market today but also meets the future requirements that our market will have to adhere to.

The demand for high energy efficiencies, low Global Warming Potential and improved corporate social responsibility is increasing. As a result, regardless whether operating on a global, national or regional basis, all businesses are being forced to look at their own buildings and how their decisions on capital plant will impact them over the lifespan of the product. As such, R410A systems are becoming less viable with the cost of refrigerant increasing, with R410A cost per kilogram climbing rapidly based on the high GWP and the ETS Tax imposed.

The future-proof solution to meet changing environmental demands and corporate responsibility

As business owners, design engineers, installers and suppliers of HVAC systems in New Zealand, it is our duty to provide the developers and building owners a robust future-proof solution to best suit their building and occupants needs. It is also imperative we observe occupant safety and ensure our decisions will not have a lasting impact on our environment for the future.

BDT and Mitsubishi Electric are dedicated to leading the market with innovative products and initiatives which ensure our social corporate responsibilities are upheld; protecting ourselves, our stakeholders and the public.

Case Study – Mt Ruapehu Ski Club

Tuesday 12th of February 2019
When Ruapehu Ski Club was looking to replace hot water facilities in one of their buildings called ‘The Lodge’ on Mount Ruapehu, the club wanted to find a modern, efficient way to provide these important creature comforts for their club members

A major part of RSC’s aim when doing this refurbishment was to reduce the peak load of electricity used during the ski season. They required a hot water heating system that would work in the cold climate and still produce hot water efficiently.

The club building is able to house up to 70 people as well as leisure, cooking, wash facilities and ski workshop facilities.

The Challenge

Five existing hot water cylinders which used direct electric elements providing 900 litres of potable hot water needed to be replaced, alongside the heater in the drying room which consisted of a fan blowing over a 6kW heating element.

The Hot Water Solution

The installation consisted of two 11.2kW Ecodan Hot Water Heat Pump Hydrobox Systems and two 600L Hot Water Storage Cylinders. The outdoor units incorporate the Mitsubishi Electric patented Zubadan Flash Injection Technology which means they are able to maintain their full 11.2kW capacity with 55°C hot water output down to an ambient temperature of -15°C; suitable for the alpine conditions at Mt Ruapehu.

The Ecodan Hydrobox contains hydraulic components, pump, expansion vessel, flow sensor and a refrigerant to water heat exchanger, making it simple to connect just water piping to the cylinders. The two 600L Cylinders contain 40m coils to maximise the heat exchange inside the cylinder. Three temperature sensors are mounted in each cylinder to monitor the tank temperature from top to bottom.

Modulating control valves have been installed to balance the hot water provided by each of the two independent systems, allowing for automatic isolation of each cylinder if temperature cannot be maintained. Electric immersion elements are also installed in the hot water cylinders. These are controlled by the Building Management System to provide additional heating capacity if required during periods of high hot water consumption and to provide legionella prevention at scheduled intervals. The elements also serve as a backup heat source if the Ecodan Systems are shut down for maintenance. The club can reduce peak electricity consumption using the integrated FTC5 Controllers scheduling function so that hot water recovery times are outside of kitchen operating hours.

As the drying room is in continuous use during the ski season, an inverter driven 3.5kW HyperCore High Wall Heat Pump provides ample heat and is also controlled remotely depending on occupancy, further improving efficiency in place of the 6kW fan blown heater.

The BMS Solution

BDT provided a Building Management System to monitor and control the domestic hot water and space heating systems in the lodge. The controls package consisted of a web-enabled Black Diamond Controls Central Controller, BACnet Controller and three MelcoBEMS Mini’s to provide Modbus interfaces to the Mitsubishi Electric Ecodan and HyperCore Systems.

In addition, the site energy consumption is monitored via a newly installed Modbus Energy Meter connected to the main incoming supply. This allows the club to monitor their year-on-year energy savings and real time consumption.

Due to the remote nature of the site, the control system was developed to provide redundancy and automated email paging in the event of faults or persistent low hot water temperature situations.

The BMS provides a web interface which allows specific club member access to remotely monitor and adjust operating parameters such as temperature set point and time schedules, via a secure connection.

This system has seen its first season on the mountain, having successfully delivered hot water to Ruapehu Ski Club and we will continue to monitor the system year on year.



Ecodan Smart Energy Monitoring and Management

Monday 14th of January 2019
State of the art energy monitoring and management of the Ecodan Heat Pump System means families now have the visibility and freedom to efficiently manage their overall household power consumption for heating and hot water. Energy monitoring and control ensures households can take advantage of off-peak tariffs or improve the use of solar panels, providing them the ability to save even more on their power bill.

End-users can now easily check the energy data of the Ecodan Heat Pump with the ability to view electricity consumption and heat output on the remote controller.

Data Shown on the Remote Controller

  • Consumed electrical energy for space heating, cooling and domestic hot water (kWh)
  • Delivered energy for space heating, cooling and domestic hot water (kWh)

Other Features
  • Daily, monthly and yearly data are stored and can be displayed using the main remote controller
  • External power meter and heat meter can be connected for accurate measurement
  • An SD card is included for storing usage data

Auto Adaptation

Our advanced Auto Adaptation Function measures the room temperature and outdoor temperature, calculating the required heating capacity for the room.

The flow temperature is automatically controlled according to the required heating capacity, while the optimal room temperature is maintained at all times; ensuring the appropriate heating capacity and preventing energy wastage.

Future Room Temperature Estimation

By estimating future changes in room temperature, the system works to prevent unnecessary increases and decreases in the flow temperature. Auto Adaptation maximises both comfort and energy savings.

2-ZONE CONTROL

Using Ecodan, it is possible to control two different flow temperatures, thereby managing two different heating load requirements. The system can adjust and maintain two flow temperatures when different temperatures are required for different rooms; for example, controlling a flow temperature of 45°C for the bedroom radiators and another flow temperature of 35°C for the living room underfloor heating.

Ecodan – Why Water?

Monday 17th of December 2018
The exact origin of using water for heating has some debate, but it dates back to around the 13th century where monks diverted river water and heated it in furnaces to warm their monasteries. With warm buildings in the cold months, the benefits of this ingenuity were obvious and over the years inventors and engineers have gradually found ways to improve on the concept. Following the industrial revolution, Charles Hood wrote the first engineering handbook for hot water heating in 1837, which was published in revised editions for 50 years.

Why Water?

Hydronic heating systems are commonly used throughout Europe and other parts of the world. In fact today, over two thirds of the world use warm water central heating.

So why is water such a good option to use?

  • Water is abundantly available, non-toxic and non-hazardous.
  • Water can retain heat longer than most other substances.
  • It has a unique heat capacity; the presence of hydrogen bonds causes water to heat and cool slower than other substances.

The Benefits of Water

If you remember back to school science class, water has a very high “specific heat capacity”. What this means for us is once the water is up to the desired temperature in our heating circuit, the water holds its heat energy well. Therefore it is a good substance to use to distribute heat.

The benefits of using heating circuits are:

  • Comfort levels are high because the whole house is heated.
  • There is no fan blown air so circulation of allergens and dust are reduced.
  • Condensation is minimised.

What About Efficiency?

The ideal temperature to run underfloor heating is ideally somewhere between 35°C and 40°C (radiator temperatures vary according to the output capacity of the radiator). This makes using hot water heat pumps ideal for supplying heat to the emitter.

When using gas or oil boilers the temperature of the water coming out of these systems is too hot for underfloor heating. As a result the water needs to be blended down in temperature to mitigate the risk of overheating the house or even damaging the floor. Aside from this, the carbon emissions of these types of heating by comparison to a heat pump is significantly higher. Gas has over 5 times the emissions and oil boilers have over 8 times the emissions of heat pumps.* This is thanks in part to the clean electricity provided to us in New Zealand by the hydroelectric stations and in part to the high efficiency of the Ecodan Air to Water Heat Pumps.

When choosing central heating, Ecodan is unrivalled for performance, efficiency and carbon emissions.

*Based on New Zealand electricity grid emission factors for 2015 (MBIE) and using average COP values for Ecodan Air to Water Heat Pump based on BSEN14511 testing.

The Concept

In the commercial arena using water is commonplace because these efficiencies have a direct implication on budgets, as building owners take in to account running costs as a part of their budget forecast. If running costs, efficiency and being eco-friendly is so important to those building large buildings, how much more important should it be to homeowners running their own homes?

When clients who design or install commercial heating systems hear about these systems they can immediately see the benefit and understand the concept as this applied engineering used in the commercial world directly translates into what we are doing domestically.

Why Ecodan?

The Ecodan Range by Mitsubishi Electric is unrivalled for performance, efficiency and quietness. Crucially with hot water heat pumps you want the heat pump to deliver all the heat you need without backup or supplementary heat sources.

With New Zealand being an unregulated market place for this technology, there are a number of manufacturers with systems which are designed for warmer climates, and have particularly poor performance in colder weather and therefore rely on inefficient back up as the norm. With Ecodan you can be assured that the performance delivered via our Power Inverter and Zubadan Systems will work throughout all New Zealand conditions.**

** All units are rated at 2°C ambient, Zubadan units hold full capacity and 55°C output water down to -15°C.

The Future

As the need to be more energy efficient becomes a higher priority to us, we will see that air to water heat pump systems are the future of home heating, and remember the Ecodan System can also generate all your domestic hot water too. If your client likes the idea of a hydronic heating system, Ecodan is the energy efficient answer.









Ecodan Central Heating and Hot Water

Wednesday 21st of November 2018
In New Zealand central heating is fast becoming the heating system of choice where whole home comfort is highly desirable. Whether it is underfloor heating, or radiators as used throughout Europe, both are becoming increasingly popular in the domestic market. So, the question must be asked, what is the best way to generate heat? Also, what factors are important to consider when choosing a central heating system for your client?

Consider how much energy your house uses and what the best ways might be to reduce this energy consumption

This is a big subject to cover, and addressing it means that we will have to challenge the way things have always been done by giving detailed attention to areas we often overlook.

These areas include the effects of the day to day weather on a home and if the insulation levels of the home mean that the energy use is higher than necessary.

Among other factors such as location and orientation, good thermal insulation reduces the effect of the surrounding weather on a home. By keeping it cooler in summer and warmer in winter, the need for cooling and heating is reduced.

Consider what the highest consumers of energy are in your home

Current statistics show that the highest consumers of energy in New Zealand homes are hot water (38%) and home heating (36%) which combined account for 74% of your energy use.

Finding the most efficient way to generate your hot water and heating therefore is an important point of consideration.

The Ecodan Range of air to water heat pumps are designed to deliver efficient, renewable heating and hot water for your home. Mitsubishi Electric are once again leading the way with the acclaimed Ecodan Range, bringing intelligent, high quality whole home heating to New Zealand.

Coefficient Of Performance

Within the industry for air to water heat pumps there is some choice on the market however the performance of the units can vary significantly. A commonly used measure is the Coefficient Of Performance (COP) which is simply the amount of electrical energy consumed compared to the system heat output. A heat source that is classed as renewable is a product that outputs at least 2.5 times the energy consumed.

For example, a COP of 1 : 2.5. A COP is a specific measure on a given day. So, if the outdoor ambient temperature is 15°C and the heat pump is putting a flow temperature of 35°C, it stands to reason that the COP on that day and time would read very differently to say an ambient temperature of 2°C and a flow temperature of 55°C. In this case the heat pump will need to work harder to pull heat from a colder ambient temperature and maintain a higher output.

Seasonal Coefficient Of Performance

What would be more accurate is a measure that rates the system seasonal performance known as Seasonal Coefficient Of Performance (SCOP), where the system is measured against year round outdoor ambient temperatures.

However, these figures can be hard to find, so how then can you make an educated choice for a system that will meet your client's needs? I would suggest that if manufacturers indicate that their systems are not suitable for colder areas of the country, or if they are reluctant to publish performance at low temperatures, then this is a good indication that their systems perform poorly in colder temperatures.

This means a back up immersion heater will have to be used, compromising system efficiency and therefore increasing environmental impact and run costs.

Simply put – not all heat pumps are the same. In some cases, the performance can be so poor that you would save your client's capital expenditure and run costs if you installed a gas central heating system.

The Mitsubishi Electric Solution

With a range of integrated products, Mitsubishi Electric will be bringing central heating and hot water solutions to our lineup. Our hot water cylinders are high quality products – pre-plumbed, pre-wired, low standing loss and using plate heat exchangers for high efficiency hot water generation.

The flow temperature controllers are the Fifth Generation (FTC5) Controllers, with unique self-learning settings for maximum efficiency, control and feedback with energy monitoring built in. All of course tied off with a single outdoor unit with the usual high efficiency and low noise you would expect from a Mitsubishi Electric unit.

Zubadan

New Generation Zubadan provides powerful heating in cold regions where most heat pumps lack in performance. Zubadan's rated heating capacity is maintained even in outdoor temperatures as low as -15°C, with guaranteed heating operation at -25°C outdoor temperature. That means Zubadan can be trusted to provide comfortable heating during severe winter months. Furthermore, faster tank heater times are achieved in low ambient temperatures compared to standard models temperature. Zubadan is available on our 8kW – 14kW models only.

Smart Energy Monitoring

State of the art energy monitoring and management of the Ecodan Heat Pump System means families now have the visibility and freedom to efficiently manage their overall household power consumption for heating and hot water. Energy monitoring means households can now easily take advantage of off-peak tariffs, giving them the ability to save even more on their power bill.

Mitsubishi Electric Introduces a New Model to the L4 Grande Range

Friday 23rd of October 2015
Mitsubishi Electric is pleased to present the latest addition to the L4 Grande Refrigeration Range, now available in both 710 Litre and 650 Litre capacities. The new 650L, available in pearl white, diamond black, and stainless steel, will cater to any family home.

The large, brightly lit French door Refrigeration compartment allows you to store foods of all types of shapes and sizes with ease, while the pull out cases in the double door freezer provide superior organisation. Combined, this layout makes the L4 Grande Range the ultimate storage solution for large families and those that love to entertain.

The L4 Grande range is designed for both larger and more efficient living. With a 3 star energy rating and low annual running costs, this is a refrigerator that has your family’s future in mind. Not only that, but the inverter compressor results in a super quiet dBA rating of 26 – a must have for open plan living spaces.

Think outside the box

Friday 23rd of October 2015
This was the design brief that inspired our engineers to go beyond the conventional, to push the boundaries and to challenge the status quo. The result, a refrigerator that is as individual as you are. Able to adapt to the lifestyle you lead, the foods you love and the way you like to cook and entertain. The Mitsubishi Electric WX is a flagship Multi Drawer Refrigerator that will take centre stage in your kitchen for years to come.

At the heart of our WX range is our unique Multi Drawer Refrigeration concept. Different foods require different temperatures for ultimate freshness and longevity. Dedicated drawers provide separate temperature controlled zones that are specifically designed so you can accommodate all types of foods at their ideal temperature, so they will stay fresher for longer. Boasting a large capacity of 743L, VIP technology - a thinner, more efficient insulation that allows the WX743 to offer such large capacity while achieving thinner exterior dimensions overall - the WX743 unique multi drawer, multi compartment layout has been specifically designed to maximise space.

Precise temperature management is achieved through a clever union of advanced inverter driven multi fan technology and 9 temperature zone sensors that are constantly monitored by intuitive control logic. Usage patterns are established over time and the Neuro Inverter Technology adjusts power levels for unparalleled energy efficiency. Inverter technology means not only has the WX been awarded the Energy Star Mark with an energy star rating of 3.5, but is also one of the quietest refrigerators in its size class at only 15 dBa.

The striking glass flat panel exterior reveals a combination of French doors at the top followed by 4 speciality drawers. This layout specifically minimizes temperature fluctuations that are the norm with conventional single door refrigerators. The refrigeration compartment boasts tempered glass shelving, flexible storage options such as adjustable door pockets, and the latest innovation from Mitsubishi Electric, the Supercool Chilling Case, set between 3 and -3 degrees. In Supercool Chilling Mode, this speciality drawer is ideal for prolonging the life of premium cuts of meat meats and fresh fish without freezing it.

The separate Versa Freezer Drawer enables food quality to be preserved for longer, without compromising on texture or original taste. With three modes, Supercool Freezing, Soft Freezing, and Hot Freezing, the Versa drawer is a helper for the everyday chef. Put your hot curry sauce straight into the freezer without damage using Hot Freeze, easily cut through frozen meat to make carpaccio with the Soft Freeze function, or maintain the texture of a high quality steak with Supercool Freezing.

Standard freezing is also available, both in the Versa drawer and in the specific Freezer Drawer. Set between -22 and -16 degrees, the freezer drawer features a sliding tray ideal for frequently accessed or flat pack items. The sliding tray can be pushed back to reveal the freezer drawer which is ideal for bulky items such as ice cream tubs and frozen vegetables.

The WX has a separate ice drawer for easy access to crystal clear, clean ice. It also boasts a Rapid Ice feature which is an added bonus for the entertainer. If guests unexpectedly pop in for cocktail hour you can speed up the ice making time for a single batch of ice, for cool drinks in no time.

Mitsubishi Electric’s industry leading humidity drawer is now even more advanced with Vitalight Technology. An amber LED light installed at the back of the humidity drawer mimics the photosynthesis process, allowing fruit and vegetables to absorb energy from the light, maintaining vitamin C levels and keeping food fresher for longer.

The sophisticated features offered by the WX743 are all accessible via an intuitive LED touch panel, which allows you to activate each function with ease.

The WX743 is available now from selected retailers with an RRP of $5,499.

There is no longer a need to compromise.

Design, performance and functionality have seamlessly come together in the new range of Multi Drawer Refrigerators from Mitsubishi Electric.

The ultimate in energy efficient home heating has arrived!

Friday 6th of March 2015
Exclusive to the Deluxe FH Series, the unique 3D i-See Sensor detects the exact position of you and your family based on individual heat signatures and provides the perfect amount of heating or cooling. The 3D i-See Sensor also acts as an advanced occupancy sensor. After a set period of time with no one in the room, the heat pump automatically switches to energy saving operation, leading to a reduction in energy usage by up to 10%!

Do you prefer to feel the heat directly but your partner does not? Simple! A breakthrough in comfort, the unique split vane design means direct and indirect air flow modes can be customised to suit both of you at the same time! This is achieved as the vanes can independently direct air upwards, downwards or to the side. This feature also makes the Deluxe FH Series perfect for heating and cooling multi-level hallways in homes.

For the ultimate in home heating, you must consider the HyperCore FH Series. Not only does this range boast the ultimate in energy efficiency and customised comfort, but with the addition of HyperCore® Technology you can rest easy knowing you and your family will be toasty warm during even the coldest days and nights. While most heat pumps produce less heat below 7°C, HyperCore® guarantees full rated heating capacity right down to -15°C and even heats down to -25°C. The Mitsubishi Electric HyperCore® Range is the only heat pump that can guarantee this level of advanced performance.

In loving memory of Ken Lilley

Wednesday 3rd of April 2013
The Black Diamond Technologies team is shocked and deeply saddened by the loss of Ken Lilley. Ken was killed in a motorbike accident Tuesday 2nd April 2013 while travelling from his holiday home in Kaiteriteri. Ken has been a key part of BDT and all of our lives for so long; his loss has left us grieving terribly. Our hearts go out to Maria, Vanessa and Jordan and the rest of Ken’s family.

Ken has been part of the BDT family since 1986, starting his early career as a South Island sales representative. Ken quickly rose to National Sales Manager before being offered a share-holding and directorship. Ken led BDT as Managing Director since 2002.

Ken was well respected across the retail and air conditioning industries for his charismatic approach, business knowledge and marketing expertise. During Ken’s career he successfully marketed and distributed a number of brands, most well-known being Mitsubishi Electric and Black Diamond.

Within BDT, his personal, family approach will be missed greatly by all staff. We have lost a captivating, innovative and creative leader. He was inspiring and always had a smile and a joke for everyone, while leading our company to success after success for decades. He leaves behind a strong organisation that will be a fitting legacy.

Those wishing to pass on their condolences can do so through BDT.

Messages can be left at ken.bdt.co.nz .

Kind Regards,

Ron Woodrow

Chairman & Founder

We’ve seen it all; the drama, the strain, the ups and downs, and the triumphs. Since first appearing on our screens in early July, the hit renovation-reality series The Block NZ has grown to become a must watch on Wednesday and Thursday nights.

With interior renovations on the houses complete, we have now seen the Mitsubishi Electric Designer Series range chosen by the couples for completing both their living rooms and master bedrooms. Available exclusively on a Mitsubishi Electric multi room heat pump system, of which each house on The Block NZ is fitted, the couples had the ultimate flexibility to choose the best Mitsubishi Electric heat pump for their design plans and room layout. And with 3 colours to choose from (glossy black, matte silver, and classic white) it was little wonder they turned to incorporating heat pumps from the Designer Series range.

Not wanting to compromise aesthetic appeal or comfort these slimline units, with their silver-bevelled edges and flat panel façade, were the perfect addition for winning over the judges and their discerning tastes.

Mitsubishi Electric sponsors new TV show "The Block NZ"

Thursday 5th of July 2012
As far as hot topics go, the upcoming renovation-reality series The Block NZ appears to have captured the nation’s attention already. It is little wonder as Kiwis have always taken pride in renovating their own homes. As a nation of 4.4 million DIY experts we have mastered combining kiwi ingenuity with leading interior design in our apartments, homes and bachs.

The Block NZ debuts here early July on the back of almost a decade of success in Australia, where the show ranks as the highest rated television series of all time. This is not to mention the international success the show has encountered with 350 episodes being produced worldwide!

The Block NZ will see four couples - siblings, spouses, best friends - compete to renovate four run-down houses in a very upmarket suburb. Room by room, week by week, they'll fix up the homes to sell at auction for the highest price - and they have to live in the houses while they do it. That means no kitchen, no bathroom, not even a clean place to sleep until that room is renovated!

With some contestants leaving their jobs to take up this once-in-a-lifetime opportunity, it is no secret that there is a lot at stake. It all comes down to the auction, which will be broadcast LIVE. All four couples will receive profits from the sale of their house on the night, and the winner will take home an additional cash prize of $80,000.

Mitsubishi Electric is proud to be a sponsor of The Block NZ, providing the contestants with products that will improve their homes and complement their designs. Heating, ventilation and insulation solutions are recognised as ways to provide tangible increases in a home’s value. So too is the importance of selecting energy efficient products to contribute to lower ongoing home running costs. And with products ranging from heat pumps to ventilation to refrigeration, Mitsubishi Electric should unquestionably be top of mind when NZers embark on a renovation project.

Don’t miss the renovation drama! The Block will air on TV3 Wednesday and Thursdays at 7.30pm from 4 July 2012.

Thursday 10th of June 2010
If you want efficient and effective home heating, Mitsubishi Electric Heat Pumps have a distinct advantage. Why?
