HCFCs制冷剂替代物研究进展及性能分析

摘要

The most important refrigerants of HCFCs in refrigeration and air - conditioning will be phased out. Alternative refrigerants choice is very important. This paper introduced several alternative refrigerants from the basic thermal physical and circulation performance, etc. , including R290, R32, R1234yf (R1234ze), etc.%目前制冷空调行业使用量最大的HCFCs制冷剂正在处于加速淘汰阶段,替代物的选择至关重要.文中从基本热物性、循环性能等多角度,具体介绍了多种HCFCs制冷剂的替代物,包括R290、R32、R1234yf( R1234ze)等,为国内HFCFs制冷剂的替代提供参考.
