Characteristics of heat pump heat exchanger

2013年9月5日 阅读:1110


Water loop heat pump air conditioning system of the basic working principles are: at the water / air heat pump heating, water circulation loop of water as a heating source; refrigeration unit, with water as the exhaust heat source. When the water loop heat pump air conditioning system heat running heat absorption than heating operation of heat circulation loop, the water temperature, to a certain extent using the cooling tower to produce heat; and circulating loop water temperature lower, to a certain extent by auxiliary heating equipment heat absorption.

Only when the water / air heat pump heating operation of heat absorption and refrigeration operation of the heat is basically the same, the water in the circulation loop can be maintained in a certain temperature range, the system efficiency.

The cooling mode process: closed compressor, four valve, a refrigerant - water tube type heat exchanger, capillary, refrigeration heat exchanger, four way reversing valve to the closed compressor

The heating mode process: closed compressor, four valve, heating heat exchanger refrigerant capillary→→- water tube type heat exchanger, four way reversing valve to the closed compressor
