Abstract
In this work, the vapor-liquid equilibrium data of two binary mixtures R32+R1234yf and R1234yf+R1234ze(E), and ternary mixture R32+R1234yf+R1234ze(E) were experimentally studied by using a liquid-recirculating analytical apparatus at temperatures from 263.15 K to 323.15 K. A set of temperature independent parameters was correlated for three binary mixtures with the PRSV+WS+NRTL model. The average absolute relative deviation(AARD) of pressure between experimental data and calculated results for R32+R1234yf and R1234yf+R1234ze(E) were 0.71% and 0.20%, respectively. The average absolute deviation(AAD) of vapor-phase mole fractions were both around 0.0016. This model was also employed to predict the ternary VLE properties. The AARD of pressure for R32+R1234yf+R1234ze(E) was 0.82%. The AAD of vapor-phase mole fractions of the system components R32 and R1234yf were both about 0.007.
