High efficiency compact rotary compressor using the new refrigerant HFC134a for automotive air conditioners.

Author(s) : HIROSE T., FUJITA T., KITAMURA T.

Summary

In response to the change to R134a, the authors developed the vane rotary compressor, which is smaller in size than, but superior in effectiveness to, the previous rotary compressor. They eliminated the problems caused by changing the refrigerant to R134a by examining the material for seals, choosing lubricating oil specifically for this compressor, and lightening lubricating conditions in the compressor, as well as reconsidering the materials for the rubbing parts. They redeveloped the seal ring, and reduced gas leakage by optimizing the oil supplying passages, thus improving compression efficiency by 15% over previous rotary compressors.
