混合制冷剂气液相平衡数据是新型制冷剂的热力学参数的重要组成部分。理论预测和实验测定混合工质的气液相平衡数据成为研究混合工质替代问题的一项迫切需要。本文基于量子化学理论，采用真实溶剂似导体模型( COSMO-RS)模拟了二元混合制冷剂(R290＋R227ea)气液相平衡性质，模拟的结果与实验结果有很好的一致性。表明运用COSMO-RS模型预测混合制冷剂的气液相平衡是可行的。

The vapor-liquid equilibrium data is an important part of thermodynamic parameters of a new refrigerant. Theoretical predic-tions and experimental measurements of vapor-liquid equilibrium data of a new mixed working fluid become an urgent need for alternative refrigerant researches. The article is based on the theory of quantum chemistry . The vapor-liquid equilibrium properties of binary refriger-ant(R290+R227ea)were modeled by COSMO-RS simulations. The simulation results could accord with the data of experiments well. It shows that COSMO-RS simulation method is feasible to predict the vapor-liquid equilibrium properties of mixture refrigerants.
