CFC-free refrigerators and CFC-containing refrigerators have basically the same characteristics in terms of overall box structure, main components, refrigeration principle, use and maintenance methods, and fault manifestation characteristics. The difference lies in the related materials and maintenance processes caused by the characteristics of the refrigerant. With the large-scale listing of CFC-free refrigerators, refrigerators in various hospitals are in the season of replacement of old and new. Due to the characteristics of the refrigerant R134a used in CFC-free refrigerators, such as good water solubility, small molecules, and strong corrosiveness, the maintenance process requirements for vacuum drying, leakage prevention, cleanliness, etc. of the system maintenance are more stringent.
