Résumé

R1234ze(E) and R1336mzz(E) are both HFOs environmentally friendly refrigerants. A new type of excellent mixed refrigerant can be formed by mixing them. For the new mixed refrigerant, it is very important to study the vapor-liquid equilibrium properties. In this study, a set of vapor-liquid equilibrium experimental devices was built based on the liquid phase circulation method, and its reliability was verified. Then, the vapor-liquid equilibrium data of five different ratios of R1234ze(E)/R1336mzz(E) mixed refrigerant were measured in the temperature range of 283.15~313.15 K, respectively. Finally, the PR+HV+NRTL model was used to correlate the experimental data. The results show that there is no azeotropic phenomenon in the experimental temperature range of R1234ze(E)/R1336mzz(E) mixed refrigerant, but the calculated data of thecorrelation model are in good agreement with the experimental data. Moreover, the maximum average absoluterelative deviation of pressure is 0.35%, while the maximum average absolute deviation of vapor phase composition is 0.0069, showing that the experimental data meet thermodynamic consistency, thus themodel can be used to calculate the vapor-liquid equilibrium properties of HFOs binary mixed refrigerant.
