Study of Technology for Refrigerant Applications 2. Lubrication of Rotary Compressor in HFC-based Alternates

摘要

Long term reliability of rotary compressor in HFC refrigerant systems is mainly dependent on lubrication of moving parts in compressor. To maintain better reliability, basic components in rotary compressor, such as refrigeration lubricant, metallic materials and oil supply systems, were evaluated. A new materials, which are compatible in HFC systems, were determined. Also the results of an accelerated life test of rotary compressor using new materials will be presented.
