Low Noise Domestic Hot Water pump Air Source FOR School Hotel
How does an Air source heat pump work?
(1) Warm air enters and refrigerant takes the heat from the air via evaporator . Cooler air exists.
(2) Refrigerant become gas with high temperature and high pressure when compressed by compressor,
(3) Cool water enters from the water tank. Refrigerant transfers the heat into water via condenser . Warmer water exists back to the tank.
(4) Refrigerant pressure and temperature decreases via the expansion valve, ready to restart the whole cycle.
