[0002] An air source heat pump is an energy-saving device that uses high-level energy to make heat flow from a low-level heat source, air, to a high-level heat source, and it is mainly composed of an air source heat pump circulation system. An air source heat pump is a device for heating water and providing heating by consuming a part of electric energy to transfer the heat in the air to water. Currently, the air source heat pumps on the market are composed of an evaporator, a compressor, a condenser, and a throttle valve. In some cold regions, the cold air will reduce the heat absorption effect of the evaporator in the air source heat pump, greatly reducing the working efficiency, with a poor heat absorption effect. Moreover, being in a cold environment for a long time will also damage the machine, resulting in a poor heating effect and reduced practicability. Content of the Utility Model
