QAHV Series: Hot Water

As a leading manufacturer of air-to-water heat pumps, Mitsubishi Electric have developed QAHV; the latest innovation in their comprehensive line-up of Hot Water Heat Pump products. QAHV has been specifically designed to produce high flow temperature up to 90°C and is suitable for commercial and industrial applications. Using natural CO2 as the refrigerant, the QAHV provides one of the lowest environmental impacts when generating 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.

Features

  • Utilises natural refrigerant (CO2)
  • High efficiency (Achieved COP 3.88*)
  • Supplies high temperature hot water of up to 90ºC
  • Operable even at low outdoor temperature of -25ºC

Stable Heating Capacities at Low Temperatures

Why is CO2 Refrigerant Used?

QAHV adopts CO2 (R744) as it is an environmentally-friendly, natural refrigerant which has zero Ozone Depletion Potential (ODP) and has a Global Warming Potential (GWP) of 1.

High Energy Saving Gas Cooler - Patented Technology

Unique to Mitsubishi Electric, QAHV utilises a twisted and spiral gas cooler. Using twisted pipes as water pipes and running the refrigerant pipes along their grooves helps to increase the heat-conductive area; allowing for better heat transfer and an impressive COP of 3.88*. 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.

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