北京某办公建筑竖井热压通风效果测试与分析
摘要：对北京某办公建筑的竖井热压通风系统进行了以获得通风量为目的的测试。分析结果表明，影响通风量的因素较多，主要有驱动温差和系统阻力。为了最大限度地发挥该系统的节能潜力，提出了过渡季优化利用热压通风降温的方法和随实际在室人数变化动态调整百叶的策略。同时，提出了冬季消除热压通风副作用的方法。

Test and analysis of stack ventilation in a shaft of an office building in Beijing
Abstract: The stack ventilation system in a shaft of an office building in Beijing is tested for the purpose of obtaining ventilation volume. The analysis results show that there are many factors affecting the ventilation volume, mainly the driving temperature difference and the system resistance. In order to maximize the energy-saving potential of the system, the method of optimizing the use of stack ventilation for cooling in transition seasons and the strategy for dynamically adjusting the opening and closing of louvers with the actual number of people in the room are proposed. At the same time, a method to eliminate the side effects of stack ventilation in winter is put forward.
Keywords: stack ventilation; ventilation volume; office building; driving temperature difference; neutral pressure level;
