    摘要: Use of a double bond-containing hydrofluoroolefin refrigerant causes a problem that it generates hydrogen fluoride by cleavage and decomposition under influence of oxygen, leading to degradation of the materials and the refrigeration oil used in the refrigeration apparatus and causing troubles in the refrigeration apparatus.It is possible to provide a high-reliability longer-lasting refrigeration apparatus by inexpensive method, by using a double bond-containing hydrofluoroolefin refrigerant in a refrigerating cycle having a refrigerant circulation route extending from a compressor 1, via a condenser 2, an expansion mechanism 3, and an evaporator 4, back to the compressor 1 that contains an ester-based refrigeration oil containing an unsaturated fatty acid as a constituent fatty acid.

    摘要: The present invention provides a mixed ester of pentaerythritol or a mixed polyhydric alcohol and carboxylic acids; the mixed polyhydric alcohol consisting of pentaerythritol and dipentaerythritol represented by formula (I), and the carboxylic acids comprising 3,5,5-trimethylhexanoic acid and 2-propylheptanoic acid. The mixed ester exhibits excellent properties (e.g., miscibility with a refrigerant that comprises fluoropropene, low-temperature properties, oxidation stability, oxidation-hydrolysis stability, and lubricity) in a well-balanced manner while having the viscosity within the range required for a refrigerant oil, and may be used in an industrial lubricant (e.g., refrigerant oil) and the like.
