摘　　要：根据威尔逊(Wilson)等人拟合的Martin-Hou状态方程及辅助方程式导出了R134a的其他热力性质计算方程,用VisualBasic6.0语言编制了采用R134a的单级制冷循环热力计算程序和绘图程序,并给出了绘图程序绘制的R134a单级制冷循环性能指标变化曲线图和诺模图。All the equations for calculating R134a's thermodynamic properties were derived from the Martin-Hou state equation and other ancillary equations given by Wilson and others. Using Visual Basic 6.0 language, the programs for single-stage refrigeration cycle thermodynamic calculation and drawing were developed. Based on the result of drawing program, the relative single-stage refrigeration cycle performance index diagram and nomogram for R134a were given.
