摘要
随着经济发展和技术进步,人们越来越注重通过提升建筑室内空气品质营造健康舒适的室内环境,室内空气污染物浓度水平是反映室内环境健康程度的重要指标.为揭示建筑物室外和室内的PM2.5污染物浓度分布规律,在北京市某5A级办公建筑室内外进行了PM2.5污染物浓度监测.监测结果表明,室外PM2.5质量浓度分步规律与太阳辐射强度正相关,且在新风开启工况下,室内污染物浓度仍无法满足健康建筑标准.根据监测结果,进一步提出了新型新风净化系统,可根据室内空气污染物水平对新风进行按需供给,营造健康室内环境.
With economic development and technological progress,people are paying more and more attention to building a healthy and comfortable indoor environment by improving the indoor air quality of buildings.The concentration level of indoor air pollutants is an important indicator reflecting the health of the indoor environment.In order to reveal the distribution of PM2.5 pollutant concentration in outdoor and indoor buildings,PM2.5 pollutant concentration monitoring was conducted indoors and outdoors in a 5A grade office building in Beijing.The monitoring results show that the step-by-step law of outdoor PM2.5 mass concentration is positively correlated with the solar radiation intensity,and the indoor pollutant concentration still cannot meet the healthy building standards when the fresh wind is on.According to the monitoring results,a new fresh air purification system was further proposed,which can supply fresh air on demand according to the indoor air pollutant level and create a healthy indoor environment.
