Provided is a refrigerating machine oil which comprises an ester between a polyol consisting of at least one of pentaerythritol and dipentaerythritol represented by formula (I) and 2-propylheptanoic acid, and is characterized in that the refrigerating machine oil can be used in combination with a refrigerant consisting of 1,3,3,3-tetrafluoropropene (HFO-1234ze). When the refrigerating machine oil is used in combination with a refrigerant consisting of HFO-1234ze, excellent miscibility with the refrigerant, lubricity, thermal and chemical stability and the like can be achieved.
The present invention provides a stable working fluid for use in a viscous coupling which is insusceptible to viscosity decreases due to thermal decomposition as well as viscosity increases or gelation, which comprises a specific polyorganosiloxane as a base oil having one or more selected from the group consisting of sulfonate, phenate and salicylate incorporated therein, and which may further comprises sulfur, phosphorus and chlorine compounds incorporated therein.
