The less oil technique research is based on R290 rotary compressor for the purpose of decreasing the refrigerant charge amount of R290 room air conditioner to satisfy the demand of IEC standard 60335-2-40. Firstly, according to the demand of R290 refrigerant application, the key points of R290 compressor design was indicated. Then, the less oil rotary compressor was designed, and the CFD simulation of the oil feed structure was confirmed. Thirdly, the oil feed test was evaluated. Moreover, the performance and reliability tests were completed. Lastly, the result of refrigerant charge amount decrease of R290 room air conditioner was obtained by test, and the system performance was also confirmed. The results show that the less oil rotary compressor not only effectively decrease the refrigerant charge amount of R290 room air conditioner but also can achieve the same performance and reliability of the compressor and system. That is to say, the less oil technique is one of the most important directions of rotary compressor development.
