【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。

【英文摘要】 For R407C,the concentration of it's components,HFC32/HFC125/HFC134a,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.
