Working principle of electrical cabinet air-conditioner
Air conditioners are divided into single-cooling air conditioners and dual-purpose air conditioners. The working principle is the same. Most of the refrigerants used in air conditioners are Freon. The characteristics of Freon are: when it changes from gaseous to liquid, it releases a lot of heat. When changing from a liquid to a gaseous state, it absorbs a lot of heat.
Air conditioners are divided into single-cooling air conditioners and dual-purpose air conditioners. The working principle is the same. Most of the refrigerants used in air conditioners are Freon. The characteristics of Freon are: when it changes from gaseous to liquid, it releases a lot of heat. When changing from liquid to gas, it will absorb a lot of heat. (That is, the first heat absorption gasification and then liquefaction heat release) air conditioning is designed according to this principle.
The compressor compresses the gaseous refrigerant into a high-temperature and high-pressure gaseous refrigerant, and then sends it to the condenser (outdoor unit) to dissipate heat and become a liquid refrigerant at normal temperature and high pressure, so the outdoor unit blows out hot air.

Then it goes to the capillary tube and enters the evaporator (indoor unit). As the space after the refrigerant reaches the evaporator from the capillary tube suddenly increases and the pressure decreases, the liquid refrigerant will vaporize and become a gaseous low-temperature refrigerant, thus absorbing a large amount of heat. The evaporator will become cold. The fan of the indoor unit blows the indoor air through the evaporator, so the indoor unit blows cold air; the water vapor in the air will condense into water droplets after encountering a cold evaporator and flow out along the water pipe. This is why the air conditioner will discharge water.
When heating, there is a component called a four-way valve, so that the flow direction of the refrigerant in the condenser and evaporator is opposite to that during cooling, so when heating, cold air is blown outdoors, and hot air is blown by the indoor machine.
In fact, it is the principle of discharging heat when liquefying (changing from gas to liquid) and absorbing heat when vaporizing (changing from liquid to gas) learned in junior high school physics.
