Refrigerants and refrigeration oil are key to the normal operation of the cold storage refrigeration system. Mixing different refrigerants and mismatching refrigeration oil models will seriously affect the stability of system operation, hidden dangers of equipment failure, and increase operation and maintenance costs.

         Different refrigerants have great differences in physical and chemical properties. Mixing them will damage the refrigeration cycle, reduce refrigeration efficiency, may also produce harmful gases, corrode pipelines and equipment components, and shorten the service life of equipment. Mismatched refrigeration oil models will lead to reduced lubrication effect, increased wear of the compressor, and even faults such as cylinder sticking and shaft seizing, affecting the normal operation of the unit.

         Such hidden dangers are easy to be ignored. It is necessary to strictly select the corresponding types of refrigerants and refrigeration oil according to the equipment requirements, eliminate the problems of mixing different refrigerants and mismatched refrigeration oil models, ensure the efficient and stable operation of the refrigeration system, and reduce the incidence of faults.
