You should know the normal working condition of the compressor in the cold storage
1. The suction temperature of the compressor should be 5-15℃ higher than the evaporation temperature. 2. The discharge temperature of the compressor R22 system must not exceed 150℃. 3. The oil temperature of the compressor crankcase must not exceed 70℃. 4. The suction pressure of the compressor should correspond to the evaporation pressure; 5. The compressor discharge pressure R22 system must not exceed 1.8MPa. 6. The oil pressure of the compressor is 0.12-0.3MPa higher than the suction pressure. 7. Cooling water volume and water temperature, the outlet temperature of the condenser should be 2-5℃ higher than the inlet 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 sounds, and all parts of the body should be normal. 10. The condensing pressure should not exceed the compressor discharge pressure range.
