The conventional heat pump comprises an evaporator, a compressor, a condenser and an expansion valve which are cyclically connected by a pipeline (copper pipe), and a refrigerant in the pipeline can be circulated and moved in each component. In use, the liquid refrigerant enters the evaporator and absorbs external heat in the evaporator to evaporate into a gaseous state, after which the gaseous refrigerant is further compressed by the compressor to increase the temperature, and then the high-pressure gaseous refrigerant enters the condenser and is condensed. The water in the device exchanges heat to release heat and liquefaction, and the water in the condenser thus heats up. Finally, the liquid refrigerant moves to the expansion valve and is depressurized, and then enters the evaporator again and is recycled.
