| Abstract: |
| In order to get the thermophysical properties of mixed refrigerants R1234yf/R134a, the PVT properties of mixture refrigerant R1234yf/R32 with mass fraction 15%/85%, 25%/75% in the range of 253-313 K were measured by using high-precision PVTx apparatus which is based on the Burnett method. The gas virial equation of these mixed refrigerants was then fitted. The detailed data were provided as the basic thermal physical property of the refrigerant for the further research. |
