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,

How to deal with the high pressure overload of the chiller

When the condenser heat dissipation is poor, the compressor efficiency is low and the operating current increases. When the high pressure rises to 19Kg/cm2, the compressor trips under the protection of the high pressure switch and the compressor stops runPﰨ2
