摘要：
The present invention relates to a lubricated refrigerant for use in refrigerators employing hydrofluorocarbon coolants such as R 134a, R 32, R 125 and the like. The lubricated refrigerant contains fluorocarbon coolant, synthetic oil and a carbodiimide compound represented by the following general formula. R.sub.1 --N.dbd.C.dbd.N--R.sub.2, wherein R.sub.1 and R.sub.2 represent hydrogen atoms or hydrocarbly groups or nitrogen and/or oxygen containing hydrocarbly groups, and R.sub.1 and R.sub.2 may be the same or different groups. The refrigerant composition according to the present invention preferably contains said hydrofluorocarbon coolant and said lubricant at a given blending ratio.
