摘　　要：根据现有的HFC152a/HCFC2 2的泡、露点实验数据 ,拟合出适用于计算其热力学性质的Peng Robinson方程的二元交相作用系数 ,并由此制作了混合工质HFC152a/HCFC2 2 (质量分数为85% /15% )的压焓图及饱和性质表 .在以温度和压力为基准的饱和性质表中 ,列出了温度在- 80℃～ 10 0℃、压力在 10kPa～ 3MPa之间 ,该混合工质的饱和热力性质 .图和表所示的热力性质包括温度、压力、比容、比焓、比熵、比火用、干度等 ,同时还提供了制作图表过程中物性的计算公式 。Based on the bubble point and dew point data of mixture refrigerant HFC152a/HCFC22, the interaction coefficient of Peng Robinson equation, which is suitable to calculate the mixture thermodynamic properties, was determined, and the pressure enthalpy diagram and the saturated properties were made. Saturated properties tables covering the temperature range of -80～100 degree centigrade and the pressure range of 10 kPa～3 MPa were listed with the temperature and pressure basis, respectively. The thermodynamic properties include temperature, pressure, specific volume, enthalpy, entropy, exergy, quality etc.. The equations to calculate the thermodynamic properties were also presented.
