Abstract:
PROBLEM TO BE SOLVED: To provide a lubricating oil composition for a refrigerator that is used for a refrigerator using a refrigerant containing a specific polar structure, such as a fluoroether compound usable in a current vehicle air conditioning system, or the like, and has superior compatibility with the refrigerant, favorable sealing properties, a low coefficient of friction at a sliding part, and superior stability.SOLUTION: The lubricating oil composition for the refrigerator uses a base oil mainly containing at least one kind of oxygen-containing compounds selected from polyoxyalkylene glycols, polyvinyl ethers, copolymers of poly(oxy)alkylene glycols or monoethers thereof and polyvinyl ethers, polyol esters, and polycarbonates.
Abstract:
PROBLEM TO BE SOLVED: To provide a foam-inducing additive to be an alternative to known silicon-containing foam-inducing additives which are not always suitable for all refrigeration systems.SOLUTION: This lubricant composition includes a synthetic lubricant base oil, preferably polyol ester, and a polyether foam-inducing additive. The composition is suitable for use in a refrigeration system, particularly with HFC refrigerant gases.
Abstract:
PROBLEM TO BE SOLVED: To provide a lubricant composition which is friendly with the global environment and can form a thin and uniform lubricating film. SOLUTION: The lubricant composition is obtained by dissolving or dispersing a lubricating polymer including a film-formable perfluoropolyether based lubricating polymer and a hydrofluoroether represented by the formula: Rf-O-R (wherein Rf is a 1-5C fluorine-containing alkyl group and R is a 3-6C alkyl group or a 1-5C fluorine-containing alkyl group, provided that the total number of carbons in Rf and R is not less than 4) and having a surface tension of not less than 14 mN/m in a fluorine-containing ether.
