Summer is a period of frequent cold storage failures, and many cold storage will have a situation where the temperature cannot be lowered and the cold storage fan compressor does not stop. Today, Nanjing Snow Refrigeration will take you to understand some common cold storage failures, just to give you the solution.
Fault 1: Frost on the surface of the evaporator in the cold storage leads to a decrease in the cooling effect
Solution: artificial defrosting in cold storage, electrochemical frost to remove frost.
Fault 2: Refrigerant leakage leads to the problem that the temperature cannot be dropped
Solution: Check the leakage points of pipelines, valves and other components for repair.
Fault 3: The expansion valve is blocked by ice and dirt, resulting in the inability to reduce the temperature of the warehouse
Solution: Clean the spool and adjust the size of the valve port.
Fault 4: The air cooler does not rotate or freezes behind, resulting in abnormal storage temperature
Solution: Clean the back area of ice, replace the heating pipe, replace the fan motor.
Fault 5: Low compressor efficiency leads to overload operation
Solution: Check the wear of cylinder liners and piston rings for replacement.
Fault 6: The freezing of the cold storage caused by the loss of temperature in the cold storage
Solution: Check the connection between the cold storage door and the storage board to adjust and reglue.
There are still many common faults in cold storage, which need to be judged and repaired according to the actual situation. When summer comes, everyone should pay attention to the maintenance of cold storage, this article is introduced here, I hope it will help you
