REFRIGERATING MACHINE OIL COMPOSITION

Title:

REFRIGERATING MACHINE OIL COMPOSITION

Document Type and Number:

WIPO Patent Application WO/2007/105452

Kind Code:

A1

Abstract:

Disclosed is a refrigerating machine oil composition characterized by containing a mixed base oil having a kinematic viscosity at 40˚C of 0.11-8 mm2/s and composed of a low-viscosity base oil (A) having a kinematic viscosity at 40˚C of not more than 5 mm2/s and a high-viscosity base oil (B) having a kinematic viscosity at 40˚C of 20-400 mm2/s. The low-viscosity base oil (A) and the high-viscosity base oil (B) are respectively composed of at least one substance selected from mineral oils, synthetic hydrocarbon compounds, oxygen-containing compounds and sulfur-containing compounds. This refrigerating machine oil composition is improved in energy saving performance since it has a low viscosity. In addition, since this refrigerating machine oil composition has good sealing property and excellent load resistance, it can be used in various refrigeration fields, particularly in a closed type refrigerating machine.
