The company has developed an evaporative cooling space energy dual source heat pump unit, including compressor, four-way valve, first three-way valve, first heat exchanger, functional module, second heat exchanger, solar heat exchanger and gas-liquid separator; The four-way valve and the first three-way valve control the circulation of refrigerant medium between the compressor, the first heat exchanger, the second heat exchanger and the solar heat exchanger. The solar heat exchanger includes a heat storage tank that can store heat. In the heating mode, the refrigerant medium of the heat pump unit can be heated directly or indirectly by the heat storage tank, which is used to improve the heating efficiency of the heat pump unit and significantly increase the application prospect of the heat pump unit in high latitude and cold areas; At the same time, the evaporative cold space energy dual source heat pump unit of the utility model is equipped with an external pipeline on the heat storage tank to provide the excess hot water in the heat storage tank for daily use, which expands the function of the heat pump unit.
