热力控制型通风房间通风效率的表达式
Equation of ventilation efficiency in thermally controlled ventilation rooms
摘要：
分析了影响热力控制型通风建筑温度分布的因素。根据相似原理综合各因素得到了两种形式的综合量：无量纲的相似准则和热分层高度等量纲不为一的综合量。用平均量纲一过余温度和通风效率（待定综合量）与其他已定综合量确定了室温垂直分布特征的表达式。对有关文献中的实验和模拟计算数据进行了回归分析，获得了通风效率特征方程式的一种具体形式。
Abstract：
Analyses the factors influencing air temperature distribution in thermally controlled ventilation rooms. Obtains two kinds of quantity group based on the similitude principle, i.e. the dimensionless similarity criterion and the dimensional thermal stratification height. Presents the equation of the characteristics of air vertical temperature distribution using the mean dimensionless excess temperature and ventilation efficiency as undetermined group and the other groups as determined ones. Concludes a concrete form of the criterion equation of ventilation efficiency by the regression analysis of the experimental and numerical simulation data in literatures.
Keywords:ventilation, temperature distribution, ventilation efficiency, criterion equation, thermal stratification height
