In concerning with the trend for the phase out of CFC's,we have developed the technology for the rolling piston type rotary compressors for refrigerators using HFC134a. It is known that the reliability of compressors is less when using HFC134a for conventional compressors without any modifications than that when using CFC12. We have estimated some kinds of refrigerating oil,materials for motors,mechanical parts, and their compatibility for HFC134a. The life test using the compressors with the new oil,motor materials,and modified mechanical parts was carried out and it has been found that the reliability equivalent to that of CFC12 system can be maintained. However,this test only could estimate there liability of compressors under a certain limited condition. So we are now continuing extend examination to adapt the above-mentioned technology to various actual use.
