摘要
讨论了现行自然通风计算方法中存在的问题 ,分析了室内空气密度、空气动力系数和室外风速等参数对热压和风压计算的影响 ,提出了考虑密度随温度非线性变化与室外风速垂直梯度的计算方法和公式。算例表明 ,计算参数的不同选择会产生计算结果的较大差异。
Discusses the deviation from an assumed linear relationship of air density with air temperature in current natural ventilation calculation, analyses effects of the indoor air density, aerodynamic coefficient and outdoor wind velocity on the results of thermal and wind pressure calculation, and demonstrates that the results varies apparently with differently selected parameters.
