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.
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.
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.
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.
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.
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:
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 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.
