摘要:
Bearing grease includes an ether base oil and a urea thickener, and is used in an atmosphere of a fluorine compound-based refrigerant. No grease is eluted for a long period in a bearing with use of the bearing grease. Moreover, since a collection system is unnecessary unlike a lubricating oil, the surroundings of the bearing can be made compact. Accordingly, the bearing with use of the bearing grease is easily applicable to automobiles and a variety of industrial machinery as an energy collection apparatus using the Rankine cycle.

摘要:
This invention relates to the use of chloro-trifluoropropenes as refrigerants in negative-pressure liquid chillers and methods of replacing an existing refrigerant in a chiller with chloro-trifluoropropenes. The chloro-trifluoropropenes, particularly 1-chloro-3,3,3-trifluoropropene, have high efficiency and unexpectedly high capacity in liquid chiller applications and are useful as more environmentally sustainable refrigerants for such applications, including the replacement of R-123 and R-11.
摘要:
Provided is a lubricating oil composition for a refrigerator which uses a base oil including as the main component 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. The lubricating oil composition for a refrigerator is used for a refrigerator that uses, as a refrigerant, a fluorine-containing organic compound, which is a refrigerant applicable to current car air conditioner systems or the like and has a specific polar structure, and has favorable sealing property, a low coefficient of friction factor in a sliding part, and excellent stability as well as excellent compatibility with the refrigerant.
