How does the water heater heat the water?
The working principle of water heater feed water heating: the compressor compresses the returning low-pressure refrigerant and turns it into high-temperature and high-pressure gas flowing through the pipe. The high-temperature and high-pressure gaseous refrigerant flows through the copper pipe wound outside the water tank, and the heat is transferred to the water tank through the copper pipe , Conduct heat exchange, the cooled gaseous refrigerant becomes liquid under the continuous action of pressure, and enters the evaporator after passing through the expansion valve. As the pressure of the evaporator drops suddenly, the liquid refrigerant quickly evaporates and becomes gaseous and absorbs A lot of heat.
At the same time, 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 temperature of the air drops rapidly and becomes cold air and is discharged into the kitchen. Then the refrigerant that has absorbed a certain amount of energy flows back to the compressor and enters the next cycle.
Precautions for the use of water heaters:
1. The power supply of the water heater must have a reliable grounding wire, and the household power supply system must have a leakage protection device.
2. Three-eye sockets with fixed specifications must be used, and the phase, neutral, and ground wires must be connected in the correct position.
3. The location of the power socket should be set in a place where water cannot be splashed, and a splash-proof socket should be used.
4. Water heaters equipped with leakage protection plugs must not use power sockets with switches.
