| 摘 要： | 为了获得混合制冷剂R134a/R290的热物性数据,搭建了高精度PVTx实验系统。以Burnett法为基础,测定了R134a/R290质量分数为50%/50%、55%/45%和60%/40%在温度为252 K~320 K的PVT性质,并且拟合了三种不同配比的混合工质的气态维里方程。实验数据与方程的平均误差为1%左右,具有较好的重合度。

| Abstract: | 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. |
