摘要
根据MBWR状态方程及 4个辅助方程式导出了新工质R1 2 5的其它热力性质计算方程 ,用VisualBasic语言编写了R1 2 5的热力计算程序和压焓图的绘图程序 ,计算结果与文献 [1 ]给出的数据进行了比较 ,并给出了由计算结果编制的热力性质表与lgP h图。
All the equations for calculating R125′s thermodynamic properties were derived from the MBWR equation and other four ancillary equations.Using Visual Basic language,the programs for thermodynamic calculation and drawing were developed.The result was compared with data given in reference.Based on the result of calculation,the thermodynamic tables and pressure enthalpy diagram were compiled.
