| 摘 要： | 通过对实验数据及常规计算方法的分析，提出了一种计算常压下卤代烃制冷工质导热系数的新方程．新方程形式简单，计算方便，仅需已知物质的分子量、临界参数等基本物性数据就可以精确地计算出卤代烃制冷工质在常压下的导热系数．用新方程计算的12种卤代烃制冷工质的导热系数与其实验数据的比较表明，新方程计算的相对偏差基本在±7％以内，总平均偏差约为2.7％．

| Abstract: | A new generalized correlation is presented for the thermal conductivity of fluorocarbon refrigerants at constant pressure based on the comparison of reliable experimental data and the theoretical formula. The new formula can be used to calculate the thermal conductivity of methane and ethane family of fluorocarbon refrigerants with high accuracy. The inputs are the critical pressure, the critical temperature, and molecular weight. The range of application for the reduced temperature is from 0.6 to 1.2 and that for the comprssibility factor at the critical point is from 0.225 to 0.283. Compared with the experimental data, the calculation deviation is within ±7％, the total absolute average deviation is 2.7％． |
