酒店建筑物主风口侧新风口空气污染控制研究

Study on Air Pollution Control of Fresh Air Inlet of Main Air Port in Hotel Buildings

对三座大型综合性酒店建筑物的主风口侧新风吸入口空气品质实测调查发现,该侧室内排风混入比例高达17.5％左右,对新风引入构成约束。用连续点源扩散理论分析了排风混入的影响因素;试验讨论了排风量的变化对新风吸入口部位和室内空气品质的影响程度;提出了确定主风口侧排风量的计算公式;为工程设计提供了参考依据。

The air quality of the fresh air inlet of main air port in three large - scale hotels is surveyed. The mixing proportion of inside exhaust air to fresh air inlet is about 17.5% , thus the rate of fresh air is restrained. The influencing factors of exhaust air mixing have been analyzed by continuous point diffusion theories. The influence of exhaust air rate upon the air quality at fresh air inlet and in the room is discussed. The calculation formula for determining the exhaust air rate of main air port has been given out as a reference to the project design.
