Do you know how a water heater heats water?
The working principle of water heater heating water:
The compressor compresses the returned low pressure refrigerant into high temperature and high pressure gas, which flows through the pipeline. The high-temperature and high-pressure gaseous refrigerant flows through the copper pipes wound outside the water tank, and the heat is transferred to the water tank through the copper pipes for heat exchange, and the cooled gaseous refrigerant becomes liquid outside the water tank. Continuous action of the tank. The pressure enters the evaporator after passing through the expansion valve. With the sudden drop in evaporator pressure, the liquid refrigerant quickly evaporates into a gaseous state and absorbs a lot of heat.
At the same time, under the action of the fan, a large amount of air flows over the outer surface of the evaporator, and the energy in the air is absorbed by the evaporator. The air temperature drops rapidly, becomes cold air, and is expelled into the kitchen. Then the refrigerant that has absorbed a certain amount of energy flows back to the compressor and enters the next cycle.
