主烟道横截面积一定时，采用数值模拟方法模拟并分析了热压对12层住宅厨房等截面排烟道系统排烟能力的影响。结果表明：随着室内外温差的增大，热压的积极作用更明显，主烟道出口处排烟能力更高，主烟道内压力分布更趋向均匀。
主煙道橫截麵積一定時，採用數值模擬方法模擬併分析瞭熱壓對12層住宅廚房等截麵排煙道繫統排煙能力的影響。結果錶明：隨著室內外溫差的增大，熱壓的積極作用更明顯，主煙道齣口處排煙能力更高，主煙道內壓力分佈更趨嚮均勻。

If the cross-sectional area of the main flue is certain,numerical simulation methods are used to simulate and analyze the effect of thermal pressure on the central exhaust system of a 12-storey residential building. The results indi-cate that,with indoor and outdoor temperature difference increasing,the thermal pressure plays a more active role,and the fume exhausting ability of the outlet of the main flue becomes higher,and the static pressure inside the main flue becomes more balanced.
