Heat Pump Water Heater

The compressor absorbs low temperature and low pressure gaseous refrigerant from the evaporator, using input electrical energy, the compressor will compress the refrigerant into high temperature and high pressure state, and then the heat will be exchanged by the condenser which improves the water temperature to working temperature; while the high pressure liquid refrigerant after chilled to release of heat is throttled and depressurized by the throttle valve it will have forcible convection by the fan in the evaporator then it will absorb heat from air and evaporate it to low pressure, gaseous refrigerant and then it will be absorbed into the compressor to do work, such whole process will be circulated repeatedly to make domestic water.
