Numerical Studies on Purification Effect of a Novel Double Skin Facade Integrated with Photocatalysis

摘要

This study presents a novel concept of photocatalysis integrated double skin facade (DSF).The influence of the positions of photocatalysts loaded in the DSF on the purification efficiency is studied by using Computational Fluid Dynamics (CFD) methods.The results show that the loading position of photocatalysts has a significant impact on the efficiency.Compared with the cases loading photocatalysts on the surfaces of inner glass and external glass,loading photocatalysts on the surface of blinds is the best way for purifying air.When photocatalysts are loaded on all the surfaces in DSF,the maximum purification efficiency reaches 62.75 ％ in the study case.
