摘　　要：介绍R1234yf,R1234ze(E),R452B,R513A和R515A这5种典型HFO类工质的基础特性,分别针对水冷式和风冷式冷水机组的典型设计工况,开展上述5种工质与R134a,R410A和R22这3种传统工质的循环性能初步对比分析,结果表明:R1234ze(E)和R515A具有较高的COP和较低的排气温度,但单位容积制冷量偏低;R452B虽然具有较高的单位容积制冷量,但还须在系统方面进行深入优化以提升机组的整体能效。The fundamental properties of R1234 yf,R1234ze（E）,R452 B,R513A and R515 A are introduced.Based on typical design operating condition for air-cooled and water-cooled chiller,the refrigeration cycle performance of these HFOs working fluids are compared with that of R134 a,R410A and R22.The conclusion indicates that,R1234ze（E）and R515 A system have higher COP,lower discharge temperature and lower unit volume cooling capacity,and R452 B system has higher volume cooling capacity,but need further improvement of unit energy efficiency.
