摘　　要：目的处理呼吸幕墙通道间流动的空气,研究解决工程中节能及室内空气净化的问题.方法设计一种光催化呼吸幕墙空气净化器装置,利用纳米TiO_2光催化技术,降解流经幕墙通道空气中的污染物,然后将净化后的清新空气送入室内;建立实验模型,设置对比试验,测试净化器在不同设置情况下室内TVOC的数值.结果不同条件下(风速、百叶角度、空气与TiO_2接触面积不同时)净化器的最优状态:当光催化呼吸幕墙空气净化器处于三挡风速,按有双层附着TiO_2的百叶窗帘并且百叶角度为180°时为最优状态.在最优状态下该净化器对TVOC的净化率可达84%.结论该净化器节能环保,净化能力强,无二次污染且充分利用了呼吸幕墙空间以及太阳能,展现出其节能环保的优势,推动净化产品的更新换代,具有广阔的市场前景.This paper was proposed to investigate the purification process of the air that flows through the respiratory curtain wall in order to save energy and improve indoor air quality. Firstly,the photocatalytic respiratory curtain wall purification device was designed using nanometer TiO_2 photocatalysis technology to degrade pollutants that flow through the curtain channel,and the pure and fresh air will be sent into the room after purification. Then the experiment model was established based on a large number of comparative experiments and testing VOC values under different settings conditions of the purifier. The results showed that the max purifying rate of the proposed air purifier could reach up to 84% by proper setting of velocity,layer and angle. The proposed purifier achieved a strong purifying capacity with non-secondary pollution by taking of full advantage of the space of curtain wall channel and solar energy,and showed the advantage of energy conservation and environmental protection.
