The invention discloses a heat
recovery type
air cooling heat pump unit comprising a first
refrigerant circulating
system and a second
refrigerant circulating
system, wherein the first
refrigerant circulating
system comprises a first compressor, a first four-way valve, a second four-way valve, a first air side fin type
heat exchanger, an air conditioner side
heat exchanger, a first air-liquid separator, a total heat
recovery heat exchanger, a hot water circulating water pump, a heat preservation water tank and a valve; the second refrigerant circulating system comprises a second compressor, a third four-way valve, a fourth four-way valve, a second air side fin type heat exchanger, an air conditioner side heat exchanger, a third reservoir, a second air-liquid separator, a partial heat
recovery heat exchanger, a heat preservation water tank and a valve. According the invention, heat is ensured to be effectively recovered and reused, and environment is protected from
thermal pollution, thereby being environmental friendly and saving energy. In addition, the defects that air conditioner heating and daily
hot water supply can not be carried out simultaneously, and the traditional total heat recovery air conditioner system which only has a single heat recovery system can not produce higher-temperature daily hot water at low temperature in winter can be effectively overcome.
