摘　　要：本文介绍了高效强热商用涡旋技术给空调系统带来的性能提高和节能效果。两种方式应用高效强热商用涡旋技术:a)高效节能优化方案:采用同等容量压缩机,提高制冷/热量的同时大幅提高能效比;b)低温制热优化方案:采用较小容量压缩机,维持一定制冷量的同时保证低温情况下的制热量。通过实测,证明了高效强热商用涡旋压缩机的两种应用方案均能为用户节省电费,尤其是作为低温热泵用于寒冷地区具有良好的效果,在环境温度为-15℃时,热泵依然运行稳定且制热性能良好,在商用市场上具有很好的应用前景。This paper discusses the capacity and energy efficiency improvements that can be achieved on air - conditioners by adopting Enhanced Vapor Injection Technology （EVI）. Two common approaches can be used when applying EVI： （a） use the same size compressor and increase cooling and heating capacity with the most significant energy consumption savings on low ambient heating or （b） use a smaller compressor, maintain the cooling capacity, increase the heating capacity and experience energy efficiency gains at all operating conditions. Extensive laboratory and field tests have demonstrated safe reliable operation and excellent performance in ambient of -15℃ and lower.
