ABSTRACT:
A centrifugal compressor refrigeration system is made, employing a halocarbon gas refrigerant in contact with a lubricant composition comprising 100 parts of castor oil and from 20 parts to 110 parts of a chemically and thermally stable, low viscosity blending fluid, soluble in castor oil; wherein the halocarbon gas is only slightly soluble in the lubricant composition, which provides good lubricity over the expected temperatures and operating conditions of the refrigeration system and is highly resistant to chemical reaction with the halocarbon and/or materials in the refrigeration system.
