Compressor failure and elimination

The compressor is the heart of the refrigeration system. It sucks 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 high-temperature and high-pressure refrigerant liquid to the exhaust pipe to provide power for the refrigeration cycle.

Principle of oil bath air filter

The filter is cylindrical, and the cylinder is divided into three parts: the outer cylinder, the inner cylinder, and the air outlet pipe. The upper part of the inner part is a swirling plate (or guide vane) and a filter screen, and the lower part is connected to the outer cylinder, and the bottom of the cylinder is filled with compressor oil (waste oil).
