Window air conditioners are divided into two types: single-cooling air conditioners and heating and cooling air conditioners. The working principles are basically the same. They all use the principle of energy conversion when the medium phase changes in the heat exchange system to achieve work requirements. Taking air conditioning and refrigeration as an example, the compression in the heat exchange system The machine 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 becomes a liquid refrigerant at room temperature and high pressure, and then goes to the capillary tube and enters the evaporator (indoor unit). After the capillary tube reaches the evaporator, the space suddenly increases and the pressure decreases, the liquid refrigerant will vaporize and become a gaseous low-temperature refrigerant, thereby absorbing a large amount of heat, the evaporator will become cold, and the fan of the indoor unit will cool the indoor air. The air blown through the evaporator, so that the indoor unit blows out cold air. the
