摘要 HFC/HC混合工质的气液性平衡实验研究结果表明,该类型混合工质大多存在共沸现象。根据形成共沸点的热力学条件,以PR状态方程结合vdW混合法则,利用建立的二元相互作用系数k_(ij)差值关联模型,对10种HFCs工质(HFC23、HFC32、HFC125、HFC143a、HFC134a、HFC152a、HFC227ea、HFC236fa、HFC236ea、HFC245fa)与3种HCs工质(HC290、HC600a、HC600)相互组合而成的30种HFC/HC混合工质进行了共沸点判断和共沸点性质推算,并与已有气液相平衡实验数据的体系进行对比。结果表明该方法可用于推算HFC/HC混合工质共沸点性质。 The previous reported experimental results of vapor-liquid equilibria for HFC/HC mixtures indicate that these mixtures normally show azeotropic behavior.Based on the thermodynamic conditions for azeotropy,a model using PR equation of state and van der Waals mixing rule is developed,in which the binary interaction parameter k_（ij） is predicted by the differential-model.The model is used to determine the binary homogeneous azeotropes for 30 types of HFC/HCs mixtures,which consist of 10 HFCs（namely HFC23,HFC32,HFC125,HFC143a,HFC134a,HFC152a,HFC227ea,HFC236fa, HFC236ea,and HFC245fa） and 3 HCs（namely HC290,HC600a,and HC600）.The prediction results are compared with the reference data,and show good agreements.
