The compressor is a driven fluid machine that elevates low-pressure gas to high-pressure gas. It is the heart of the refrigeration system. It sucks in low-temperature and low-pressure refrigerant gas from the suction pipe, drives the piston to compress it through the operation of the motor, and discharges the high-temperature and high-pressure refrigerant gas to the exhaust pipe to provide power for the refrigeration cycle.

This achieves a refrigeration cycle of compression → condensation (heat release) → expansion → evaporation (heat absorption). Compressors are divided into piston compressors, screw compressors, centrifugal compressors, linear compressors, etc. The entry introduces the working principle, classification, accessories, specifications, operation requirements, compressor production, common faults and environmental protection requirements, selection principles, installation conditions and development trends of the compressor.
