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.

Causes of non-condensable gas in refrigeration system

Causes of non-condensable gas in refrigeration system 1. Insufficient emptying of the refrigeration system before charging the refrigerant Before charging the refrigerator, the compressor cylinder in the refrigeration system, the condenser, the evaporator, and the piping of the system were filled with air. In order to eliminate these air before charging the refrigerant, the interior of the refrigeration system Vacuuming,
