The normal interlocking and stable start-stop of the cold storage unit are the key to ensuring the efficient operation of the refrigeration system. The unit's failure to interlock, frequent start-stop or failure to start will directly affect the refrigeration effect, increase equipment loss and operation and maintenance costs, and are common and influential operation hazards.

         If the unit fails to interlock, it will lead to the failure of coordination between various components and disordered operation of the refrigeration system; frequent start-stop will intensify the wear of core components such as the compressor, shorten the service life of the equipment, and increase energy consumption; failure to start will directly cause the interruption of refrigeration and affect the safety of stored goods.

         It is necessary to regularly check the interlocking system, electrical circuit and the status of core components, investigate problems such as poor line contact and abnormal parameters, standardize operation procedures, and timely handle faults to ensure the unit's normal interlocking, stable start-stop and the continuous and efficient operation of the refrigeration system.
