摘　　要：对于混合工质R407C,在生产过程中其组分HFC32/HFC125/HFC134a浓度难以严格达到23%/25%/52%,并且由于试验装置的泄露,其组分的浓度也会有所偏差。针对上述问题,讨论了R407C各组分浓度误差小于5%时对压缩机性能实验—流量计法的影响,从而提高测试结果的精度。For R407C, the concentration of it＇s components, HFC32/HFC125/HFCI34a, is not controlled to 23%/25%/52% strictly during the production. In addition, because of the leakage of test device, there is deviation in the component＇s concentration. According to these, discusses the impact of concentration error （≤5%） on the performance test of compressor-flow counter method, consequently improves the test precision.
