摘    要:本文提出了一个预测液相制冷剂混合物导热系数的方程。这种预测方法仅需要已知混合物各组元的导热系数、分子量、摩尔成分等几种物性,就可预测混合物的导热系数.本预测方程形式简单,并通过与文献试验数据及其它预测方程比较,证明本预测方程的计算精度比其它方程较高,能够满足工程要求。

关 键 词:混合制冷剂  导热系数  预测方程

Abstract:An empirical method was put forward to predict the thermal conductivity of liquid mixtures in this paper. According to the method, once the thermal conductivity, the molar weight, the mole fraction, and some other properties of the components are known, the thermal conductivity of the mixtures can be determined. The method was checked with the experimental data in literatures and compared with other prediction methods. All results showed that the accuracy of the method is higher than that of other methods, though its form is a little simple. Its accuracy is enough for engineering applications.
Keywords:refrigerant mixture  thermal conductivity  prediction equation
