Abstract: | The rolling piston type rotary compressor has been widely used for refrigeration and air-conditioning systems due to its compactness
and high-speed operation. The present analysis is part of a research program directed toward maximizing the advantages of
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 a rotary compressor
being used for refrigeration and air-conditioning systems was investigated. The Newton-Raphson method was used for a partial
elastohydrodynamic lubrication analysis between the vane and the rolling piston of a rotary compressor. The results demonstrated
that the vane thickness and the center line position of the vane significantly influenced the friction force and the energy
loss between the vane and the rolling piston. |
