Abstract:
Provided is a lubricating oil composition for a refrigerator, the refrigerator using a refrigerant which has a low global warming potential and is applicable to, in particular, current car air conditioning systems or the like, that is, the refrigerant including at least one kind of fluorine-containing organic compounds selected from compounds represented by the following molecular formula (A) or including a combination of the fluorine-containing organic compound and a saturated fluorinated hydrocarbon compound, CpOqFrRs (A) where: R represents Cl, Br, I, or H; p represents an integer of 1 to 6, q represents an integer of 0 to 2, r represents an integer of 1 to 14, and s represents an integer of 0 to 13; and provided that, when q represents 0, p represents 2 to 6 and one or more carbon-carbon unsaturated bonds are included in molecules, in which the composition comprises a base oil including as a main component a polyvinyl ether-based compound having an alkylene glycol unit, or a polyoxyalkylene glycol unit and a vinyl ether unit in a molecule and having a hydroxyl value of 15 mgKOH/g or less.
