热分布系数作为评价通风系统效率的重要指标之一，迄今除试验外尚无其他定值方法。应用作者的温度预测方法，证实了热分布系数是热分层高度及房间辐射传递因子的函数。得出的热分布系数数学表达式与试验结果吻合良好。
The heat distribution coefficient is one of the important indexes to evaluate the efficiency of the ventilation system. So far, there are no other fixed values except the test. Using the author’s temperature prediction method, it was confirmed that the heat distribution coefficient is a function of the thermal stratification height and the room radiative transfer factor. The mathematical expression of the heat distribution coefficient obtained agrees well with the experimental results.
