<p>PROBLEM TO BE SOLVED: To provide a lubricant composition for a refrigerator, which is used for a refrigerator using a coolant having low global warming factor and especially having a specific structure such as an unsaturated fluorohydrocarbon compound which is a coolant capable of being used for an existing car air conditioner system, air-conditioning equipment and the like, and has excellent compatibility to the coolant and is excellent in thermal and chemical stability.SOLUTION: A lubricant composition for a refrigerator uses a coolant containing at least one kind of fluorine-containing organic compound selected from compound represented by the following molecular formula (A) or a combination of the fluorine-containing organic compound and a saturated fluorohydrocarbon compound, and contains a base oil and a sulfur-containing aromatic compound. COFR(A), where R represents either one of Cl, Br, I and H, p is an integer of 1 to 6, q is an integer of 0 to 2, r is an integer of 1 to 14 and s is an integer of 0 to 13, but p is 2 to 6 and one or more carbon-carbon unsaturated bond in a molecule when q is 0.</p> |
