REFRIGERATOR OIL COMPOSITION

摘要

PURPOSE:To provide a lubricating oil desirable for, e.g. a refrigerator using a fluorine-compound refrigerant such as R-134a reduced in depletion of the ozonosphere. CONSTITUTION:A mineral oil or a synthetic oil is mixed with 2-95wt.% organic compound containing 2-30 carbon atoms and having a viscosity of 100 cps or below at 25 deg.C and a volume resistivity of 1.0X10<5>OMEGAcm or above at 25 deg.C. The obtained refrigerator oil is one well-balanced between compatibility with, e.g. R-134a and volume resistivity and is satisfactorily applicable to a refrigeration system using R-134a instead of conventional R-11 or R-12.
