Reasons for insufficient refrigerating capacity of freezer

1. There is too much dust in the filter screen of the air filter, the dirt in the coil and fin of the condenser has not been removed, and the air inlet or outlet is blocked, which will cause the airflow in the condenser to be unsmooth, the exchange rate of the condenser is greatly reduced, resulting in insufficient refrigerating capacity of the freezer.
2. If the set temperature is too high during refrigeration, the duty cycle of the compressor will increase and the average refrigerating capacity of the commercial freezer will decrease: if the set temperature is too high during refrigeration, the duty cycle of the compressor will also increase, so that the average refrigerating capacity of the commercial freezer is reduced.
3. Poor sealing performance of commercial freezer rooms, frequent opening of windows or frequent opening of new air doors for a long time will cause loss of indoor cooling.
4, freezer room heat load is too large, such as indoor high-power electrical appliances or heat sources, or indoor personnel too much, room temperature is obviously difficult to drop down.
