摘　　要：利用NISTREFPROP数据库计算HFC1 2 5 /HCs(包括丙烷、丁烷、异丁烷 )三类二元混合工质的热力学性质 ,并对其理论制冷循环性能进行分析计算 ,筛选出最佳配比。结果显示其理论循环性能比HCFC2 2高 1 6 .9% 。HFC125/HCs binary mixtures were proposed to be substitute refrigerants. Based on the NIST REFPROP Database, the performances of the theoretical refrigeration cycle were calculated in and analyzed. The COP of the mixture with optimal composition is about 16.9% higher than that of HCFC22 in theory,and the discharge temperature of compressor is lower.
