摘　　要：在本世纪末即将全面禁止使用CFCs。对于R11和R12的替代工质，例如R123和R134a的热力性质已有很多文章发表。本文给出了计算工质热力性质必须的全部公式，并编制了通用计算程序，用来计算R142b、R152a等替代工质的热力性质，所得结果与现有的工质性质图表所列数据吻合。CFCs will be widely phased out by the end of this century. R134a and R123 are the general way to replace the refrigerants R11 and R12. Their thermodynamic properties were reported in many articles. This paper gives all baisc formulas and a gereral calculating program presented to computate thermodynamic properties for different alternatives such as R152a、R142b, etc. The results have a good agreement with the data of existing refrigerant diagrams and charts.
