In order to get the thermophysical properties of mixed refrigerants R134a/R290
the author built PVTx experimental system with high accuracy. Based on the Burnett method
the author measured the PVT properties of R134a/R290 with mass fraction 50%/50%
55%/45%
60%/40% in the range of 252K-320K
and fitted the gas virial equation of these mixed refrigerants. The average error between experimental data and equation is about 1%.It turned out that the experimental data agreed with the equations highly.
