principle of operation
Air conditioning is divided into single cooling air conditioning and cold and warm air conditioning, and the working principle is the same. Freon used to be the common refrigerant in air conditioning. Freon is characterized by releasing a lot of heat when it changes from gas to liquid, and absorbing a lot of heat when it changes from liquid to gas. Air conditioning is designed according to this principle. The compressor compresses the gaseous refrigerant into high-temperature and high-pressure gaseous refrigerant, and then sends it to the condenser. After heat dissipation, it becomes a liquid refrigerant at room temperature and high pressure, so the outdoor unit blows out hot air.
And then enters a capillary tube and enters an evaporator. Because after the refrigerant reaches the evaporator from the capillary, the space suddenly increases and the pressure decreases, the liquid refrigerant will vaporize and become a low-temperature gaseous refrigerant, thus absorbing a lot of heat, and the evaporator will become cold. The fan of the indoor unit blows out indoor air from the evaporator, so the indoor unit blows out cold air. When the water vapor in the air meets the cold evaporator, it will condense into water droplets and flow out along the water pipe, which is why the air conditioner will produce water.
