通风与TiO2涂料光催化治理室内污染物的研究

将通风工程技术和室内污染控制技术相结合，通过模拟室内环境条件，研究了紫外光照射时，上送上排、上送下排和置换通风三种不同通风方式下，室内环境中涂有二氧化钛涂料时，对甲醛的去除作用。实验结果表明：在不同的送风量条件下，有紫外光照射时，二氧化钛涂料在置换通风方式下对室内甲醛的降解效果相对较好。

Study of ventilation and TiO2 coating as a photo catalyst in clearing indoor airborne pollutants

The ventilation and indoor contaminant control engineering have been combined in this article. By simulating indoor environment, this article investigates the remove effect of TiO2 coating on the concentration of airborne pollutants indoors under UV light with three different air distribution systems： the up-in and up-out ventilation, the up-in and low-out ventilation and the displacement ventilation. The results show that： Under the different ventilation quantity, TiO2 coating exposed to UV light with the displacement ventilation can effectively eliminate formaldehyde.
