which directly affect the quality of stored goods, increase energy consumption and operation and maintenance costs, and at the same time increase equipment load and shorten service life.

         Insufficient cooling capacity is mostly caused by insufficient refrigerant, blocked pipelines, poor heat dissipation or abnormal compressor operation. Slow cooling is related to low heat exchange efficiency, poor thermal insulation effect and poor air circulation. The two affect each other, leading to failure to meet the required temperature and humidity of the cold storage.

         It is necessary to timely check the refrigerant stock, pipeline smoothness and heat dissipation, calibrate the equipment operation parameters, optimize thermal insulation and air circulation, ensure the efficient operation of the refrigeration system, and avoid problems such as goods deterioration and equipment loss.
