| 摘 要： | 包含一个可调参数的Peng-Robinson状态方程可准确计算混合致冷剂的饱和压力及气液平衡,但对液相容积的计算误差稍大。本文针对非共沸混合工质R22/R114和R13B1/R152a进行了计算,同时也计算了两种共沸工质R500和R502,并与实验数据作了比较,获得了较满意的结果。

| Abstract: | This paper applies Peng-Robinson equation of state to the calculation of the thermodynamic properties and vapour-liquid equilibrium of refrigerant mixtures with a focus on non-azeotropic refrigerant mixtures R22/R114 and R13B1/R152a, azeotropic refrigerant mixtures RS00 andR502 because of their wide application. It shows that PR equation of state can be used to predict the bubble-point pressures and the vapour-liquid equilibrium as well as the liquid volumes of azeotropic refrigerant mixtures. For non-azeotropic refrigerant mixtures, e, g. R22/R114, the deviation for liquid volumes is a bit larger, but it still can meet the demands of engineering application in general. The results, compared with expermental data, are highly satisfactory. |
