Summary

With the wide promotion of energy saving and environmental protection, the working efficiency of Room Air Conditioner (RAC for short) system become more and more important, in addition, to improve the function of RAC on the living comfort, the demand of heating capacity especially at low ambient temperature condition of RAC become a urgent issue needs to be resolved. Firstly, the purpose of this paper was introduced. Then, the relative techniques like DC inverter, variable volume, gas injection were simply analyzed. Thirdly, a new coupling compressor with these three techniques to satisfy both high efficiency and heating capacity demands was indicated. Moreover, the detail design of the coupling compressor was described. At last, the prototype compressor was designed and assembled to validate the effect on RAC system. According to the test result, this coupling compressor has significant effect on RAC system as we expectation. The maximum heating capacity increasing up to 185% by compare to the base system at -15°C ambient temperature condition, which can reduce half time to achieve the same room temperature rising. Furthermore, the Annual Performance Factor (APF for short) efficiency of the RAC system increased by about 6%.
