135 ABSTRACT Disclosed is the use as a lubricant for refrigera- tion systems, in which a fluoroalkane refrigerant is employed, of a fluorine-containing aromatic compound represented by the following formula: R(XRf)n (I) wherein X represents an oxygen or a sulfur atom, R represents an n-valent unsubstituted or substituted aromatic group having from 6 to 60 carbon atoms, n is an integer of from 1 to 4, and Rf represents an unsubstituted or partially substituted fluorocarbon residue having from 1 to 25 carbon atoms in which the ratio of fluo- rine atom to carbon atom is at least 0.6, and the main chain of which may have at least one ether linkage therein. This fluorine-containing aromatic compound not only exhibits excellent miscibility with fluoroalkane re- frigerants, such as HFC-134a, over a wide temperature range from low to high tremperatures, but is also excellent in properties required for lubricants for use in refrigeration systems, such as heat resistance, lubrication properties, low moisture absorption and electrical insulation properties, so that it is ex- tremely useful as a lubricant for use in a refrigera- tion equipment.
