Technology and principle of refrigeration compressor

The compressor is the core part of a cooling system, a driven fluid machine that turns low-pressure gas to high-pressure gas. It is widely used in many fields of cooling system, laser industry , cold chain logistics, medical beauty equipment, charging station, server and beyond. Because of its small size, light weight and low energy consumption, the micro compressor is essential in micro cooling systems.

How does a compressor work?

Firstly, the whole refrigeration process needs the following machine: a micro compressor, a condenser, a capillary throttle valve, an evaporator and some necessary copper tubes.

There is a certain kind of refrigerant in a micro compressor, like R22, R410a or R134a. Through the compressor, the refrigerant inside is turned into high-temperature and high-pressure gas and channeled to the condenser through the tube. When it arrives at the condenser, the gas can be cooled down to the normal temperature, high-pressure gas. It then comes to the capillary throttle valve where the space is so narrow that the gas turns into low-temperature, low-pressure liquid. Through another copper tube, it turns into low-temperature, low-pressure gas thanks to the evaporator. The gas next goes back into the compressor and repeats the cycle.

In general, the whole process can be boiled down to this: compressioncondensationexpansionevaporation.
