Beschreibung
Zusammenfassung:	The refrigerator lubricating oil includes: a base oil, the main component of which is a polyol ester (A) of C3-C18 fatty acids (a1) and of a polyol (a2) that is selected from among neopentyl glycol, trimethylolethane, trimethylolpropane, trimethylolbutane, pentaerythritol, and dipentaerythritol; and a disulfide and/or trisulfide compound (B). The blended amount of the disulfide and/or trisulfide compound (B)is, in terms of sulfur, 30-10000 mass ppm with respect to the total amount of the refrigerator lubricating oil. 本发明的冷冻机润滑油包含以脂肪酸(a1)与多元醇(a2)形成的多元醇酯(A)作为主要成分的基础油、以及二硫醚和/或三硫醚化合物(B)，所述脂肪酸(a1)为碳原子数为3~18的脂肪酸，所述多元醇(a2)选自新戊二醇、三羟甲基乙烷、三羟甲基丙烷、三羟甲基丁烷、季戊四醇和二季戊四醇，前述二硫醚和/或三硫醚化合物(B)的配合量相对于冷冻机润滑油总量以硫换算值计为30~10000质量ppm。
