Lubricating oil composition for refrigerators

A method of lubricating a refrigerator, wherein the refrigerator includes a refrigerant comprising at least one 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,

• CpOqFtRs (A)
• wherein 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 the molecule,
• comprising providing in the refrigerator a lubricating composition comprising a base oil including as a main component at least one oxygen-containing compound selected from the group consisting of polyvinyl ethers, copolymers of poly(oxy)alkylene glycols or monoethers thereof and polyvinyl ethers, and polyol esters.
