摘要： There are provided a highly durable and efficient refrigerating apparatus and a lubricating oil composition that uses an HFC type refrigerant and is still free from the problem of thermal hydrolysis of polyol-ester type oil and resulting generation of carboxylic acid and sludge so that the refrigerating apparatus and the lubricating oil composition may be used stably for a prolonged period of time. A lubricating oil composition according to the invention comprises as base oil components a polyol-ester type oil formed by reacting specific polyhydric alcohol with a fatty acid, to which tricresylphosphate and epoxy compound comprising glycidyl ether or carbodiimide are added at respective specific rates. A refrigerating apparatus according to the invention uses such a lubricating oil composition as refrigerator oil and comprises a sealed electric driving compressor whose sliding members are made of a material selected from iron type materials, composite materials of aluminum and carbon, iron type materials surface-treated with chromium nitride and ceramic materials.

摘要： A refrigerant compressor is configured such that a compressor unit is installed in a hermetically sealed container, an HFC type refrigerant or a mixture thereof and a refrigerator oil having compatibility with the refrigerant are charged into the hermetically sealed container, and the refrigerator oil essentially comprises a polyvinyl ether type compound having structural units represented by the following general formula (1): ##STR1## wherein n is an integral number in the range of 1 or more, R1 to R3 are each a hydrogen atom or a hydrocarbon group having 1 to 8 carbon atoms and may be the same or different, R4 is an alkyl group having 1 to 4 carbon atoms, and units in which R4 is an alkyl group having 1 to 2 carbon atoms are 40 to 100% and units in which R4 is an alkyl group having 3 to 4 carbon atoms are 0 to 60%. As a result, the generation of a carboxylic acid caused by thermal cracking or hydrolysis due to frictional heat generated by sliding members is prevented and the generation of sludge is thereby suppressed.

摘要： The present invention is to provide a refrigerant compressor comprising a compressing element driven by a rotary shaft, for compressing and discharging a sucked HFC type refrigerant or refrigerant mainly comprising the HFC type refrigerant by the compressing element, where a rotary shaft applied with the plasma sulphonitriding treatment on the surface is used as the rotary shaft. Or a vane applied with the plasma sulphonitriding treatment on the surface of a vane made of a steel equivalent to a high speed tool steel vane or a steel equivalent to a stainless steel is used. Accordingly, a refrigerant compressor comprising a rotary shaft or a vane having a low friction coefficient in a sliding portion on the surface of the rotary shaft or the vane and a high wear resistance can be provided even in the case an ester type refrigerator oil or an ether type refrigerator oil is used as the refrigerator oil and an HFC type refrigerant is used.

摘要： A rotary compressor uses a freon without containing chlorine ions and uses polyol ester as a lubricant or plyvinyl ether as a base oil for providing a highly reliable rotary compressor, and for preventing abnormal abrasion. The rotary compressor has a roller and a vane sliding contact with an outer cirumference of the roller. A sliding contact portion between the vane and the roller is formed with a radius of curvature Rv, and satisfies T
