摘　　要：对几种 HFCs、HFEs 类新工质和混合工质M1、M2进行了以在离心式冷水空调机组中替代 CFC11为目标的理论循环性能分析。结果表明,M1具有作为 CFC11 灌注式替代物的潜力;HFC143 循环性能优良,更适合应用于新设计的系统中。Analyses on the theoretical cycle performances of some selected new HFCs and HFEs as well as their mixtures M1 and M2 were carried out, aiming at substituting CFC11 in comfort air- conditioning applications with water cooled centrifugal chillers. From these comparative analyses, it could be concluded that M1 is a promising drop-in alternative to CFC11 while HFC143 more suitable to new design applications for its comprehensively good performances of theoretical cycle.
