| 摘要: |
| 为了获得混合制冷剂R1234yf/R134a的热物性数据，本文利用Burnett法为基础搭建的高精度PVTx试验台，在温度为268~323 K时，测定了质量分数为55%/45%，50%/50%和45%/55%混合制冷剂R1234yf/R134a的PVT性质，最终拟合了三种不同配比的混合工质的气态维里方程，方程和实验数据具有较高的重合度。 |

| Abstract: |
| In order to get the thermophysical properties of mixed refrigerants R1234yf/R134a, the PVT properties of mixture refrigerant R1234yf/R134a with mass fraction 55%/45%, 50%/50%,45%/55% in the range of 268 ~ 323 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 fitted based on the measured data. It turned out that the experimental data agreed well with the equations. |
