METHOD OF OPERATING A MULTI REFRIGERATING SYSTEM

摘要

A method for operating multi-refrigerating system is provided to assign set temperature according to the characteristics of food to keep in a refrigerator and recover refrigerant remaining in the refrigerator by applying energy to the refrigerant. A method for operating multi-refrigerating system includes the steps of supplying refrigerant to any one of a plurality of refrigerators by using a compressor(S2,S3), and recovering refrigerant remaining in the one refrigerator(S5), wherein the refrigerant is recovered by applying heat energy to the refrigerant or turning on the compressor while blocking refrigerant supply to the one refrigerator.
