QAHV-N560YA-HPB For Large Capacity Hot Water Applications QAHV Hot Water Heat Pump
As a leading manufacturer of air-to-water heat pumps, Mitsubishi Electric have developed QAHV; the latest innovation in their comprehensive lineup of Hot Water Heat Pump products. QAHV has been specifically designed to produce high volume hot water and is suitable for commercial and industrial applications where hot water demand is high. By adopting Mitsubishi Electric's unique technology, QAHV ensures highly reliable performance as well as high heating capacity even at low outdoor temperatures. QAHV Hot Water Heat Pump Series * Under normal heating conditions at outdoor temp:16ºCDB/12ºCWB, inlet water temp 17ºC, outlet water temp 65ºC Main Features of QAHV • 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 Increased Energy Savings 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. Superior Heating Performance in Low Temperatures 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, ensuring highly stable operation. 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. Ideal Applications Gyms Hotels Motels Aged Care Facilities Schools Universities

Notes: *1.Under Normal heating conditions at the outdoor temp, 16°CDB/12°CWB(60.8°FDB/53.6°FWB), the outlet water temperature 65°C(149°F), and the inlet water temperature 17°C(62.6°F) *2.Under Normal heating conditions at the outdoor temp, 7°CDB/6°CWB(44.6°FDB/42.8°FWB), the outlet water temperature 65°C(149°F), and the inlet water temperature 9°C(48.2°F) *3.Under Normal heating conditions at the outdoor temp, 7°CDB/6°CWB(44.6°FDB/42.8°FWB), the outlet water temperature 65°C(149°F), and the inlet water temperature 15°C(59.0°F) *4.Under Normal heating conditions at the outdoor temp, 7°CDB/6°CWB(44.6°FDB/42.8°FWB), when the unit is set to the “Capacity Priority“ mode through the dry NC-contact. *Due to continuing improvements, specifications may be subject to change without notice *Do not use steel pipes as water pipes. *Keep the water circulated at all times. Blow the water out of the pipes if the unit will not be used for an extended period time. *Do not use ground water or well water *Do not install the unit in an environment where the wet bulb temperature exceeds 32°C *The water circuit must use the closed circuit *There is a possibility that the unit may abnormally stop when it operates outside its operating range. Provide backup (ex. boiler start with error display output signal (blue CN511 1-3)) for abnormal stop.
