| 摘 要： | 结合Peng-Robinson（PR）方程与已有的实验数据对氢氟烃混合物（HFCs）二元混合工质进行了气液平衡计算，关联得到相关体系的二元交互作用系数。在此基础上建立了二元混合物交互作用系数的推算模型，该模型能近似给出多种HFC任意二元混合的交互作用系数，由此交互作用系数计算的气液平衡压力误差一般在2％内，能满足工程需要。

| Abstract: | The calculation of vapor-liquid equilibria for binary mixtures was performed by Peng-Robinson(PR) equation and the HFCs experimental data from the references,and some correlative binary interaction parameters were obtained.Then a theoretical calculated model was set up about the interaction parameters of binary mixtures.Using the model,random binary interaction parameters of manifold HFC refrigerants can be calculated without requirement of the experimental data,and the deviation of pressure that was calculated by these theoretical binary interaction parameters is below 2%.The accuracy can meet the requirements of engineering applications. |
