How to adjust the temperature of parking air conditioning compressor?

The principle of compressor-condenser-throttle device-evaporator is the same, that is, reverse Carnot cycle, but different from refrigeration principle is the exchange of condenser and evaporator, that is, compressor-evaporator-throttle device-condenser. The compressor is the heart of the refrigeration system. Whether it is air conditioning, refrigeration, chemical refrigeration technology, etc. The compressor is an important link to ensure it! There are many kinds and forms of refrigeration compressors, which can be divided into two types according to principle: volumetric type and speed type, of which volumetric type is the most common. How does a compressor compress gas? Simply put, it is to complete the process of gas compression and transportation by changing the volume of gas! Any power equipment needs power to do work, so does the compressor, which needs a motor (motor) to drive it. Positive displacement compressors are divided into reciprocating piston type and rotary type.

The reciprocating piston changes the working volume of gas through the reciprocating motion of the piston in the cylinder; Piston compressor has a long history and mature production technology. Rotary compressors include scraper (vane) rotary compressors and screw compressors. At present, most air conditioners produced in China use rotary compressors. Screw compressor is mainly used for large refrigeration equipment, compressor-condenser-throttle device-evaporator. Its basic principle is that the compressor compresses the refrigerant into high-pressure saturated gas (ammonia or freon), and this gaseous refrigerant is condensed by the condenser. After being throttled by the throttling device, it enters the evaporator for cooling and exchanges heat with the cooled medium. For example, if the evaporator is connected to all rooms in the building, the serpentine tube in the evaporator exchanges heat with the air, and then the cold air is blown into the air in the room by blowing air. The refrigerant in the serpentine tube of the evaporator changes into low-pressure steam after heat exchange and returns to the compressor, and then is compressed by the compressor, thus completing the refrigeration system in a reciprocating manner. The heating system is basically the same principle, but in the opposite way.
