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.

Transformation project of frequency converter to air compressor

1. Brief description of working principle of air compressor: 　　 The working principle is that a pair of male and female rotors (or screws) that are toothed parallel to each other rotate in the cylinder, so that the air between the rotor teeth continuously produces periodic volume changes, and the air is transported from the suction side along the rotor axis.
