The temperature at the outlet of the compressor to the inlet of the condenser increases significantly. Due to the air in the system, the exhaust pressure and exhaust temperature increase. Air in the refrigeration system will reduce the refrigeration efficiency, the prominent phenomenon is the suction, exhaust pressure rise (but the exhaust pressure has not * over the rated value); can be in a few minutes after the shutdown, several times from the high pressure cut-off valve release air, but also according to the actual situation appropriate filling some refrigerant.
1. There is air in the refrigeration system
The temperature at the outlet of the compressor to the inlet of the condenser increases significantly. Due to the air in the system, the exhaust pressure and exhaust temperature increase. Air in the refrigeration system will reduce the refrigeration efficiency, the prominent phenomenon is the suction, exhaust pressure rise (but the exhaust pressure has not * over the rated value); can be in a few minutes after the shutdown, several times from the high pressure cut-off valve release air, but also according to the actual situation appropriate filling some refrigerant.
2. There is refrigerant oil in the evaporator pipeline
During the refrigeration cycle, some refrigeration oil remains in the evaporator pipeline. After a long period of use, when there is more residual oil in the evaporator, it will seriously affect its heat transfer effect and cause poor refrigeration. Remove the evaporator, blow it and dry it. If it is not easy to disassemble, it can be blown with air from the evaporator inlet. Remove the refrigerant oil from the evaporator.
3. The heat dissipation of the condenser is not good
If the condenser heat dissipation is not good, it will cause the cooling capacity of the refrigeration equipment to decrease, or even not cooling. Clean the condenser, pay attention to clean the stolen goods inside the fins, and pay attention to the condenser air outlet without obstacles. If it is a water-cooled condenser to clean up the scale.
