Claims5
A lubrication method, comprising:
- storing a lubricating oil composition which comprises an ester as a lubricating base oil in a storage unit, and
- applying the lubricating oil composition stored in the storage unit to a sliding unit in a refrigerant circulation system via a circulation type supply unit,
- wherein the sliding unit is a unit which is provided with a pair of sliding members facing each other and relatively moving, and slides through a sliding surface in at least one of the sliding members;
- wherein at least one of the sliding members comprises at least one selected from the group consisting of
- a liquid crystal polymer and
- a polyetheretherketone;
- wherein the sliding member further comprises a solid lubricant and a reinforcement fiber;
- and
- wherein a viscosity of the lubricating base oil based on the ISO viscosity grade is VG2 or more and VG3 or less.
