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.

Compressor overheating

The compressor is overheated, causing it to stop shortly after start-up (protector action). Please check whether it is:; Insufficient or excessive refrigerant, please fill the leak and evacuate, add enough refrigerant or release excess refrigerant. The capillary assembly (including the filter) is clogged and the suction temperature rises. Please replace the capillary assembly.
