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: The present invention relates to a refrigerator oil composition which comprises 70 to 98 wt % of a paraffin base oil having a pour point of not more than -35.degree. C., a sulfur content of not more than 50 ppm (parts per million), and a kinematic viscosity at 40.degree. C. of 5 to 500 cSt (centistrokes) and 30 to 2 wt % of a naphthene base oil having a pour point of not more than -35.degree. C., a sulfur content of 0.05 to 1 wt % and a kinematic viscosity at 40.degree. C. of 5 to 500 cSt, and in which the sulfur content is 0.01 to 0.10 wt %.The refrigerator oil composition of the present invention effectively prevents the formation of valve sludge. The refrigerator oil composition of the present invention is also excellent in anti-wear properties. Furthermore the refrigerator oil composition of the present invention is excellent in stability and baking resistance in the condition that is in contact with the refrigerant (Furon) and further is excellent in low temperature solubility. Moreover the refrigerator oil machine oil composition of the present invention contains as a main component a paraffin base oil which is steadily available.
