Beschreibung
Zusammenfassung:	This refrigerator oil composition: is used in a refrigerant comprising a mixture of an unsaturated hydrofluorocarbon compound, a saturated hydrofluorocarbon compound, and CO2; comprises at least one substance selected from among polyoxyalkylene glycols, polyvinyl ethers, copolymers of poly(oxy)alkylene glycols or monoethers thereof and polyvinyl ether, and polyol esters; contains a base oil having a kinetic viscosity at 100oC of 2-50 mm2/s and a hydroxyl value of no more than 5 mgKOH/g; has a low global warming potential and in particular can be used in a refrigerator system operated using a refrigerant applicable to automotive air conditioners or the like, the refrigerant comprising a mixture of an unsaturated hydrofluorocarbon compound, a saturated hydrofluorocarbon compound, and CO2; and is highly stable and highly compatible with the refrigerant.
