Summary

Vapor-liquid equilibrium (VLE) data for the mixture refrigerant R227ea + R161 are reported in the temperature range from 263.15 to 313.15 K with a single-phase circulation vapor-liquid equilibrium still. The results of the correlation of the vapor-liquid equilibrium data with PR equation of state, combined with the MHV1 mixing rule and Wilson model, are presented. The results reveal that they have a good agreement with the experiment results and the binary system R227ea + R161 is a non-azeotropic mixture, their temperature glide is within 6? The model parameters, determined from these binary data, are detained to predict the phase behavior for the later ternary system.
