Filed: 1998-11-02
Abstract: PROBLEM TO BE SOLVED: To inhibit the seizure in a sliding part of a compressor by adding an extreme pressure additive to a base oil of a refrigerator oil composition used for a refrigerating cycle using a hydrocarbon refrigerant. SOLUTION: This composition is prepared by adding 0.5-1.0 wt.% extreme pressure additive to a base oil of a refrigerator oil composition used for a refrigerating cycle using a hydrocarbon (e.g. n-propane or i-butane) as the refrigerant. A naphthenic, paraffinic, or alkylbenzene oil having a pour point of -15 deg.C or lower is used as the base oil. At least one extreme pressure additive selected from among sulfur-based ones (e.g. an organic polysulfide), halogen- based ones (e.g. chlorinated polyphenyl), phosphorus-based ones (e.g. tricresyl phosphate), and organometallic compound-based ones (e.g. lead naphthenate) is used. When a compressor is operated, the refrigerant is charged through a suction pipe 19 into a cylinder 7, is then compressed with a roller 10 and a vane 12, and is discharged into a muffler 17.  The refrigerator oil composition is supplied to the sliding faces of sliding members of the roller 10 or the vane 12 to lubricate the sliding faces and is circulated to be reused.
