新型装修材料所致室内空气污染空间特征研究

Analysis on Spatial Characteristics of Indoor Air Pollution Caused by New Decoration Materials

探明室内装修污染物浓度有利于后续空间环境治理,因此分析新型装修材料所致室内空气污染空间特征。使用污染物检测设备检测室内空间中的甲醛、苯、挥发性有机物的浓度与分布特征,并将设备采集结果输入到Airpak软件与CFD软件数值模拟室内空气污染的空间分布特征。试验结果表明新型装修材料会导致室内空间出现空气污染但是污染程度较轻,新型装修材料使用越多,空气污染浓度越高,随着时间推移,受到空气流场影响,污染物浓度有所降低,软件模拟结果显示,室内空气污染物受自然风速影响,进风口风速较高位置污染物浓度较低。

The spatial characteristics of indoor air pollution caused by new decoration materials are analyzed.Pollutant detection equipment was used to detect the concentration and distribution characteristics of formaldehyde,benzene and volatile organic compounds in indoor space.The results were input into Airpak software and CFD software to simulate the spatial distribution characteristics of indoor air pollution.Test results show that the new decoration materials will lead to slight air pollution in the indoor space.The more new decoration material used,the severer air pollution is.The pollution concentration will decrease overtime,affected by the air flow field.The software simulation result show that indoor air pollutants are influenced by natural wind speed.The pollutant concentration in the position with higher wind speed of the air inlet is lower.
