The protection device of the cold storage refrigeration system is an important barrier for the safe operation of the equipment. If the protection device frequently malfunctions, it will seriously affect the normal operation of the unit and increase the operation and maintenance costs and safety risks.

         Frequent misoperation of the protection device, mostly caused by improper parameter setting, poor line contact or component aging, will lead to frequent start-stop of the unit, intensify the wear of core components, and even cause refrigeration interruption, affecting the safety of goods storage.

         It is necessary to regularly check the parameters of the protection device, investigate line hidden dangers, timely replace aging components, and conduct standardized debugging to avoid misoperation, ensure the stable operation of the unit, and reduce the risk of failure.
