3-tetrafluoropropene) is extremely environmental-friendly and is currently considered as one of the alternative refrigerants. In this paper
the solubility of R1234ze(E) in two polyol ester oils was measured at temperatures ranging from 40 °C to 80 °C and pressures ranging from 0.123 MPa to 0.360 MPa. Additionally
the experimental data was correlated using the PR equation of state with MHV2 mixing rules and the NRTL activity coefficient model to calculate the interaction coefficient at different temperatures. Furthermore
the average absolute relative deviation between calculated value and experimental data was calculated. The results indicated that the solubility of R1234ze(E) in two polyol ester oils decreased as temperature increased. Additionally
a numerical calculation model for the equilibrium pressure and solubility was proposed using a cubic function with acceptable accuracy. In the two polyol ester oils
the deviations between calculated value and experimental data were 1.68% and 1.11% respectively. Thus
the results can better describe the phase equilibrium behavior of R1234ze (E) in the two polyol ester oils.
