Basic knowledge of refrigeration compressor (technology sharing)

Compressor, a driven fluid machine that promotes 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. Compression → condensation (heat release) → expansion → evaporation (heat absorption) refrigeration cycle.
