摘要：
A lubricating oil composition for refrigerator including a base oil and an acid scavenger, and a compressor using the composition are provided, where the acid scavenger is a polyalkylene glycol derivative represented by a formula (1) as follows:
R 1 -[(OR 2 ) e -OR 3 ] f (1)
and the base oil is at least one compound selected from a group consisting of polyvinyl ether, polyalkylene glycol and an ether-base compound represented by a formula (2) as follows,
Ra-[(ORb)n-(X)-(ORc)k]x-Rd (2)
where meanings of respective signs are as described in the specification.
