[0002] A compressor is a driven fluid machine that raises low-pressure gas to high-pressure gas. It is the heart of the refrigeration system. It sucks low-temperature, low-pressure refrigerant gas from the suction pipe, compresses it through the motor, and discharges high-temperature, high-pressure refrigerant gas to the exhaust pipe, providing power for the refrigeration cycle.

[0003] Compressors can be divided into low back pressure type, medium back pressure type and high back pressure type according to their application range. Low back pressure type (evaporation temperature -35~-15℃) is generally used in household refrigerators, food freezers, etc. Medium back pressure type (evaporation temperature -20~0℃) is generally used in cold drink cabinets, milk refrigerators, etc. High back pressure type (evaporation temperature -5~15℃) is generally used in room air conditioners, dehumidifiers, heat pumps, etc.
