The rolling piston type rotary compressor has become one of the most successful types because of its compactness and high-speed operation. The analysis described here is part of a research program directed toward maximising these advantages in refrigerant compressors. The study of lubrication characteristics in the critical sliding component is essential for the design of refrigerant compressors. Therefore, theoretical investigation of the lubrication characteristics of rotary compressor for refrigeration & air-conditioning system is studied. And the Newton-Raphson method is used for the EHI. analysis between vane and rolling piston in the rotary compressor. The results show that the rotational speed of shaft and the discharge pressure have an important effect upon the friction force and the energy loss between vane and rolling piston. This results give important basic data for the further lubrication analysis and design of the rotary compressor.
