How is the heat pump water heater working?

The internal structure of the central water heater is mainly composed of four core components: compressor, condenser, expansion valve and evaporator.

The working process of the central water heater is as follows: the compressor compresses the returned low-pressure refrigerant and turns it into high-temperature and high-pressure gas for discharge. The high-temperature and high-pressure refrigerant gas flows through the coil wrapped in the water tank, and the heat is transferred to the water tank through the coil. The cooled refrigerant becomes liquid under the continuous action of pressure, and then enters the evaporator through the expansion valve. Because the pressure of the evaporator suddenly decreases, Therefore, the liquid refrigerant rapidly evaporates into a gaseous state here and absorbs a lot of heat. Colleague, under the action of the fan, a large amount of air flows through the outer surface of the evaporator, and the energy in the air is absorbed by the evaporator. The air temperature decreases rapidly, and becomes cold air for discharge. Then the refrigerant that has absorbed a certain amount of energy flows back to the compressor and enters the next cycle. #info@heruienergy.com
