Air conditioners, i.e., room air conditioners (room air conditioners), which regulate temperature, humidity, and air conditioners in a hanging type are units for providing a space area (generally, an enclosed space) with a temperature change of process air. Its function is to regulate the parameters of temperature, humidity, cleanliness and air flow rate of air in the room (or closed space, zone) so as to meet the requirements of human body comfort or technological process. The air conditioner is divided into a single-cooling air conditioner and a cooling and heating air conditioner, the working principle is the same, and the refrigerant generally used by the air conditioner is Freon. The characteristics of freon are: when changing from a gaseous state to a liquid state, a large amount of heat is released. While changing from a liquid to a gaseous state, a large amount of heat is absorbed. The air conditioner is designed according to the principle.

The compressor is the device that turns gaseous freon into liquid freon in the air conditioner, and the compressor can make low pressure gas promote to high-pressure gas, is the heart of air conditioner.
