PROBLEM TO BE SOLVED: To obtain an additive for enhancing a refrigerant to be incorporated in an appropriate amount into a refrigerating machine oil in a compressor used for a refrigeration cycle, a cold storage cycle and an air conditioning cycle using a substitute flon refrigerant to ionize the refrigerating machine oil thereby improving compatibility between the refrigerating machine oil and the refrigerant to prevent an oil film from adhering to the inside face of a pipe line in the cycle with achievement of high heat transfer efficiency in an evaporator and a condenser to permit exhibition of high heat transfer performances inherent in itself. SOLUTION: The additive for enhancing a refrigerant comprises isopropyl alcohol as a major component and acetic acid compounds as a minor component. |
