What is the role of refrigeration compressors and how to classify them
A refrigeration compressor is a machine that increases the pressure of a gas, which acts as the "heart" in the refrigeration or heating cycle.
Compressors can be divided into two categories: volume type and speed type according to their thermodynamic principles.
1) Positive displacement compressor. A compressor that forcibly compresses a certain volume of gas to reduce its volume and increase its pressure is called a positive displacement compressor. Positive displacement compressors have two types of structures: piston type and rotary type.
2) Speed compressor. The increase in gas pressure is achieved by the velocity conversion of the gas. Under the action of the high-speed rotating impeller, the speed of the gas is greatly increased. When the gas flow is stagnant, the speed can be converted into pressure energy. This kind of compressor is called a speed compressor. Speed compressors are centrifugal, axial and mixed flow.
