摘　　要：分别对R290和R134a进行了热力学分析,采用R290对R134a成熟机组进行灌注量试验,节流元件匹配试验,不同环境温度下,R290试验机组对比变工况试验。理论及试验结果表明:R290在系统中的单位制热量约为R134a的1.37倍,R290的单位理论COP值约为R134a的94.2%;R290的制冷剂充注量为R134a的30.3%;R290专用试验机组制热性能平均为R134a成熟机组的1.27倍,COP整体略高于R134a成熟机组,尤其在低温方面(-5℃,0℃),平均为R134a成熟机组的1.05倍。One thermodynamic analysis between the propane and R134a is done.Also the refrigerant charge test,throttling ele-ment matching test and variable condition tests are all running in this paper.The performance analysis results show that,the unit heating capacity and COP in propane system are 1.37 times and 94.2 percent than R134a system,respectively.And from experi-mental tests,the refrigerant charging amounts of propane system is only 30.3 percent than R134a system.The heat performance of this propane test unit is 1.27 times than R134a mature unit.Also the whole COP of the propane test unit is a little higher,es-pecially in the low-temperature point （-5℃,0℃）,it’s 1.05 times average than the R134a mature unit.
