Abstract
A lubricating oil composition for a refrigerating machine according to the present invention includes: a base oil including as a main component at least one kind of oxygen-containing compound selected from polyoxyalkylene glycols, polyvinyl ethers, copolymers of poly(oxy)alkylene glycols or monoethers thereof and polyvinyl ethers, polyol esters, and polycarbonates; a sulfonic acid metal salt having a hydrocarbyl group; and a phosphoric acid ester. The lubricating oil composition for a refrigerating machine can enhance the abrasion resistance of a sliding part of a refrigerating machine using a refrigerant including at least one kind of fluorine-containing organic compound 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: COFR(A) [in the formula: R represents Cl, Br, I, or H; and p represents an integer of from 1 to 6, q represents an integer of from 0 to 2, r represents an integer of from 1 to 14, and s represents an integer of from 0 to 13, provided that, when q represents 0, p represents from 2 to 6 and one or more carbon-carbon unsaturated bonds are included in a molecule].
