  The invention provides a refrigerator oil composition comprising a base oil of a mineral oil and/or a synthetic oil, and containing (a) a partial ester of a polyalcohol and a fatty acid and (b) an acid phosphate or its amine salt; and a refrigerator oil composition comprising a base oil of a mineral oil and/or a synthetic oil, and containing any of (a) acid phosphates or their amine salts, (b) acetylene glycol alkylene oxide adducts, (c) potassium salts of fatty acids, etc., (d) organic acids, and (e) fatty acid amides. The refrigerator oil compositions have good lubricity and are especially effective for reducing the friction in both the oil region and the extreme-pressure region in the sliding area between aluminium materials and steel materials.

  本发明提供了一种冷冻机油组合物，包括矿物油和/或合成油的基础油，并含有 (a) 多元醇和脂肪酸的部分酯和 (b) 酸性磷酸盐或其胺盐；以及一种冷冻机油组合物，包括矿物油和/或合成油的基础油，并含有 (a) 酸性磷酸盐或其胺盐、(b) 乙二醇环氧烷加合物、(c) 脂肪酸钾盐等中的任何一种、(d) 有机酸，以及 (e) 脂肪酸酰胺。冷冻机油组合物具有良好的润滑性，尤其能有效减少铝材料和钢材料之间滑动区域的油区和极压区的摩擦。
