雾霾天气下住宅开窗通风与空气净化联合策略可行性研究
Feasibility analysis on combination strategies of window ventilation and air cleaners in residential buildings under haze weather
摘要：
雾霾天气的频繁出现导致关窗并开启空气净化器成为住宅中常用的净化手段，而长时间关窗带来的危害往往被忽视。模拟了雾霾天气下住宅中全时开窗及短时开窗2种开窗方式与空气净化联合使用时对室内细颗粒物（PM2.5）和CO2浓度的控制情况，结果表明：当室外雾霾在中度污染（室外PM2.5质量浓度200 μg/m3）以下时，可以采取全时开窗与空气净化联合策略控制室内污染物的浓度；当室外雾霾污染严重（室外PM2.5质量浓度300 μg/m3）时，可以采取短时开窗与空气净化联合策略将室内污染物浓度在大多数时间段内控制在限值以下。合理的开窗通风与空气净化联合控制策略为住宅中应对室外雾霾与室内多种污染物提供了一种途径。
Abstract：
Closing windows and turning on air cleaners are widely used as the means of purifying indoor air under haze weather in residential buildings, while the harm of closing windows continuously is always neglected. Simulates the concentration of PM2.5 and CO2 in residential buildings with air cleaners under haze weather when the windows are open in two different ways, i.e., full-time opening and short-time opening. The results show that the combination strategy of full-time opening with air cleaners can control the concentration of indoor pollutants under the moderate haze weather (200 μg/m3), and that the combination strategy of short-time opening with air cleaners can control the concentration of indoor pollutants in most of the time under the severe haze weather (300 μg/m3). Proper combination of window ventilation and air cleaners provides a convenient way to control the concentration of PM2.5 and multiple pollutants in residential buildings at the same time.
