Summary

In this paper, the differences between APF (Annual Performance Factor) of Japanese and Chinese standards were analyzed. In the APF standard of Japanese, the intermediate condition had the greatest influence on APF. Therefore, in the process of researching compressors for the Japanese market, it was necessary to focus on improving the energy efficiency level of middle and low frequency. Some ideas for the development of high-efficiency compressor was also provided. With the improvement of energy efficiency of air conditioning, compressor design should dare to innovate and dare to break through the routine. Based on innovative technologies such as rocker blade, high-efficiency technology of eccentric part of crankshaft and breakthrough of motor, the energy efficiency of compressor was greatly improved compared with the base compressor, and the improvement rate of intermediate cooling condition was 9%, and the improvement rate of other conditions was about 5%. Equipped with Japan's high-efficiency air conditioning system, the APF was reaching a higher level in the industry.
