ABSTRACT:
A refrigerating machine oil composition according to the invention comprises an alicyclic polycarboxylic acid ester compound obtained from the following compounds (a) to (c):(a) an alicyclic polycarboxylic acid having an alicyclic ring and two or more carboxyl groups, or its derivative, wherein at least two of the carboxyl groups are bonded to mutually adjacent carbon atoms on the alicyclic ring;(b) a compound with two or more hydroxyl groups or its derivative; and(c) a compound with one hydroxyl group or its derivative.It can be used together with HFC refrigerants and natural refrigerants such as carbon dioxide and hydrocarbons, to provide a satisfactory balance between all of the properties of lubricity, miscibility with refrigerants, heat and hydrolytic stability and electric insulating property.
