Abstract

The vapor-liquid equilibrium data is an important part of thermophysical properties of a new refrigerant. Theoretical predictions and experimental measurements of vapor-liquid equilibrium data of a new mixed working fluid become to be an urgent need for the researches on alternative refrigerants. The vapor-liquid equilibrium curves of binary mixtures (R1234ze(E)+R290, R290+R227ea) were simulated by COSMO-RS model which are based on quantum chemistry. The simulation results could accord with the experimental data well. It was concluded that COSMO-RS simulation method is feasible to predict the vapor-liquid equilibrium properties of mixed refrigerants.
