Normal operating conditions of the refrigeration system in operation

Normal operating conditions of the refrigeration system in operation

1. The suction temperature of the compressor should be 5-15℃ higher than the evaporation temperature and 5-10℃ higher than the brine temperature;

　　2. The exhaust temperature of the compressor for R12 system should not exceed 130℃, and for R22 system should not exceed 150℃;

　　3. The oil temperature of the compressor crankcase shall not exceed 70℃;

　　4. The suction pressure of the compressor should correspond to the evaporation pressure;

　　5. The maximum discharge pressure of the compressor R12 system shall not exceed 1.2MPa, and the R22 system shall not exceed 1.6MPa;

　　6. The oil pressure of the compressor is 0.12-0.3MPa higher than the suction pressure;

　　7. Always pay attention to the amount of cooling water and water temperature. The outlet water temperature of the condenser should be 2-5℃ higher than the inlet water temperature;

　　 8. Always pay attention to the oil level of the compressor crankcase and the oil return of the oil separator;

　　 9. The compressor should not have any knocking sound, and the heat of each part of the body should be normal;

　　 10. The condensing pressure must not exceed the compressor discharge pressure range.
