Title: LUBRICATING OIL COMPOSITION FOR CHILLER
Abstract:
Provided is a lubricating oil composition for chillers which has a low global warming potential due to a lubricating oil composition that contains a base oil and a sulfur-containing aromatic compound, and is for chillers that use a refrigerant that contains at least one type of fluorine-containing organic compound selected from the compounds represented by the molecular formula (A) below, or a combination of the aforementioned fluorine-containing organic compound and a saturated fluorinated hydrocarbon. The lubricating oil composition is used for chillers that use a refrigerant having a specific structure, such as an unsaturated fluorinated hydrocarbon, which is a refrigerant that is particularly suitable for existing car air conditioners, air conditioners, and the like, and has excellent compatibility with the aforementioned refrigerant, and has excellent thermal and chemical stability. CpOqFrRs...(A) (In the formula, R represents either Cl, Br, I, or H; p is an integer from 1 to 6; q is an integer from 0 to 2; r is an integer from 1 to 14; and s is an integer from 0 to 13; however, when q is 0, p is 2 to 6, and a molecule contains at least one carbon-carbon unsaturated bond.)
