摘　　要：针对建筑室内吸烟引发的PM2.5污染问题,结合室内颗粒物动力学模型研究在室内人员密度动态变化且吸烟率处于不同水平条件下,调控室内人体微环境PM2.5污染的需求送风特征。发现在不同的室内吸烟率和建筑层高条件下,置换通风需求送风量的峰值要低于混合通风需求送风量的峰值。同时,建筑层高增加会促进调控人体微环境PM2.5污染的需求送风量的下降。Based on building indoor PM2.5 pollution problems caused by smoking,Combined with the dynamic model of indoor particulate matter,making the study of indoor human body micro-environment needs air supply characteristics caused by PM2.5 pollution under the condition of dynamic personnel density and smoking rates.The results show that the demand air supply peak value of displacement ventilation is lower than that of mixing ventilation under the condition of different indoor smoking rates and story height.Besides,the increase of story height will promote the decline of demand air supply caused by human body micro-environment PM2.5 pollution
