Classification of refrigeration compressors for chillers In the internal structure of industrial chillers, compressors are basically necessary, so how are the compressors in different equipment classified?
Chillers are classified into refrigeration compressors according to different refrigeration conditions: Various refrigeration compressors are classified according to their working principles, which can be divided into number and speed. The volumetric motion compression part can be divided into two types: reciprocating (piston and rotation). According to the structural characteristics of rotary compressors, it can be divided into rolling piston type (also called rolling rotor type), sliding vane, and spiral type (including twin screw type, single screw type, scroll type). According to the compression process of the speed compressor, the main application is the centrifugal refrigeration compressor. According to the classification of evaporation temperature, it can be generally divided into high, medium and low compressors. High-temperature refrigeration compressor: -10℃-10℃ The temperature of the refrigeration compressor: -20℃-10℃ Low-temperature refrigeration compressor: -45℃-20℃ According to the classification of the sealing structure, it can be roughly divided into an open compressor and a hermetic compressor. Can be divided into semi-hermetic and hermetic compressor seals.
