REFRIGERATOR OIL COMPOSITION

摘要

PROBLEM TO BE SOLVED: To provide a refrigerator oil capable of sufficiently reducing both coefficients of static friction and dynamic friction at a sliding part of a refrigerant-compressor or the like. SOLUTION: The refrigerator oil composition contains a prescribed lubricant base oil and at least one kind of a nitrogen-containing oily agent selected from an amine, a carboxylic acid salt and amide of the amine. Both of starting electric power and power consumption are reduced by the refrigerator oil composition to achieve high-level energy saving because the both coefficients of the static friction and the dynamic friction at the sliding part of the refrigerant-compressor or the like can be reduced.
