Beschreibung
Zusammenfassung:	A lubricant for refrigerators using a hydrofluorocarbon such as R134a, R32 or R125 as the refrigerant, and a refrigerant composition containing the same. The lubricant comprises a synthetic oil and a carbodiimide compound represented by the general formula R1-N=C=N-R2, wherein R1 and R2 represent each independently hydrogen or a hydrocarbon group which may contain nitrogen or oxygen. The refrigerant composition comprises the hydrofluorocarbon refrigerant and the lubricant in a specified ratio.
