Summary

Economizer technology has become a critical method to improve the performance of air conditioners with rotary compressor in low ambient temperature. A novel vapor injection structure on the blade of the rotary compressor has been proposed in previous research to overcome the drawback of the traditional cylinder injection structure. Based on a verified numerical system model, the performance of an air conditioner adopting different economized rotary compressors has been investigated. The results indicate that: compared to the single cylinder rotary compressor with traditional injection structure, the rotary compressor with blade injection structure can enhance the heating capacity and COP by 12.9%~15.7% and 1.5%~4.1% in low ambient temperature, respectively. And compared to the twin-cylinder rotary compressor, the rotary compressor with blade injection structure has a competitive performance.
