Title:
REFRIGERATOR OIL
Document Type and Number:
WIPO Patent Application WO/2007/058072
Kind Code:
A1
Abstract:
Disclosed is a refrigerator oil which contains a base oil mainly containing at least one substance selected from the group consisting of mineral oils, synthetic alicyclic hydrocarbon compounds and synthetic aromatic hydrocarbon compounds and having a kinematic viscosity at 40˚C of 1-8 mm2/s. This refrigerator oil is applied to refrigerating machines whose sliding parts are composed of an engineering plastic or provided with an organic coating film or an inorganic coating film. This refrigerator oil enables to improve energy-saving performance since it has a low viscosity. In addition, the refrigerator oil has a low friction coefficient and good sealing properties. Consequently, the refrigerator oil is suitably used in various refrigeration applications, especially in closed-type refrigerating machines.
