Abstract

The coaxial cylinders method was used to measure the thermal conductivity of the R-125/R-134A (39/61) gas mixture. The experiments were carried out in the temperature range of 320–415 K and in the pressure range of 0.1–1.8 MPa. Coefficients were determined for an equation describing the thermal conductivity as a function of pressure and temperature. Thermal conductivity on the dew line and in ideal-gas state was calculated.

摘要

使用同轴圆筒法测量R-125 / R-134A（39/61）气体混合物的热导率。实验是在320-415 K的温度范围和0.1-1.8 MPa的压力范围内进行的。确定将导热系数作为压力和温度的函数的方程式的系数。计算了露线和理想气体状态下的热导率。
