What is the cause of high compressor discharge pressure?
The problem of air in the high-pressure system: air (or ammonia decomposed into non-condensable gases at high temperatures, such as nitrogen, hydrogen, etc.) is harmful in the refrigeration system, which can increase the working pressure of the condenser. If the condensing temperature is +35 ° C at that time, the corresponding condensing pressure is 12.5 Kg / CM2 gauge pressure, the pressure on the actual pressure gauge is 14 Kg / CM2 gauge pressure, which is more than 1.5 Kg / CM2 gauge air occupancy Condensed in it (theoretical basis is Dalton's law）
