Water heater refers to a device that can increase the temperature of cold water into hot water within a certain period of time through various physical principles. According to different principles, it can be divided into electric water heater, gas water heater, solar water heater, magnetic energy water heater, air energy water heater, heating water heater, etc.

Make cold air part and hot water part. In fact, these two parts are closely linked, inseparable, and must work at the same time. That is, the kitchen is cooled while hot water is produced. In other words, while cooling the kitchen, hot water is also produced


working principle

A complete domestic multi-function water heater consists of two main parts:

Its internal structure is mainly composed of four core components: compressor, condenser, expansion valve and evaporator.

The working process is as follows: the compressor compresses the returned low-pressure refrigerant and turns it into high-temperature and high-pressure gas, which flows through the pipeline. The high-temperature and high-pressure gaseous refrigerant flows through the copper tube wrapped outside the water tank. The heat is transferred to the water tank through the copper tube for heat exchange. The cooled gaseous refrigerant becomes liquid under the continuous effect of pressure and enters the evaporator after passing through the expansion valve. As the pressure of the evaporator drops suddenly, Therefore, the liquid refrigerant quickly evaporates here to become a gas and absorbs a lot of heat. At the same time, under the action of the fan, a large amount of air flows through the external surface of the evaporator, the energy in the air is absorbed by the evaporator, and the air temperature decreases rapidly, becoming cold air and discharged into the kitchen. Then the refrigerant that has absorbed a certain amount of energy returns to the compressor and enters the next cycle.

It can be seen from the above working principle that the working principle of the household multi-function water heater is somewhat similar to that of the air conditioner. The inverse Carnot principle is applied. By absorbing a large amount of low temperature heat energy in the air, the compressor compresses it into high temperature heat energy, which is transferred to the water tank to heat the water. The whole process is an energy transfer process (from air to water), not an energy conversion process. The hot water is not heated by electric heating elements, or it is heated by burning combustible gas.
