　　What should I do if the cooling water of a refrigerated chiller is not circulating?

　　Possible reasons for non circulation of cold water in a freezer:

　　1. The water level in the water tank is lower than the water inlet of the water pump.

　　2. The pipeline from the water pump to the water outlet of the freezer is blocked.

　　3. Faulty accessories or wiring.

　　The treatment method for non circulation of cold water in a freezer:

　　1. Check whether the cooling water in the water tank of the freezer reaches the minimum liquid level range of the chiller.

　　2. If the water level is confirmed to be normal, it is necessary to first observe whether the water pump experiences vibration, abnormal noise, and other conditions that affect the water flow during operation.

　　3. Check if there is output voltage at the output end of the switch power supply, etc. If there is a malfunction in the accessory or circuit, it may also cause the cooling water of the freezer to not circulate.

　　The refrigeration system often fails to absorb freezing during operation, resulting in a lack of refrigeration flow in the refrigerator. The refrigerator manufacturer can investigate the cause of the problem in the refrigerator control panel. The solution is as follows:

　　1. Use a rubber hose to fill the small supplementary freezing pipe reserved on the large pipe of the frozen storage tank (pool) back into the refrigeration circulation pump (open its small valve). Use a wrench to open the small exhaust plug of the refrigeration circulation pump (if there is any freezing, tighten it again) until there is frozen reflux into the large pipe of the frozen storage tank (pool). Open the rubber hose and check for any bubbles. If so, please continue to freeze and close the small valve until there are no bubbles.

　　2. Open the freezer for 1-3 minutes, and if there is a large amount of frozen water returning to the freezing pool in the large freezing tube, there will be no problem.

　　3. If the refrigeration machine lacks or does not have thawing, please repeat the above irrigation action.
