主　　题：Electrophoretic deposition (EPD) TiO2 Filter HVAC 

摘      要：This study used electrophoretic deposition （EPD） to apply titanium oxide （TiO2） coating on stainless steel filters and investigated the effectiveness of photocatalytic oxidation of formaldehyde by TiO2 under various conditions of heating ventilation air conditioning （HVAC）. The results showed photocatalytic efficiency could reach 35,59% at 21 ℃ and 36.39% at 26℃ with 7 photocatalyst filters and 5 UVC lamps, the overall efficiency of formaldehyde removal of 52.37% at 21 ℃, and 56.8% at 26 ℃, By all experimental data can be found that the temperature for the photocatalytic performance is not obvious in the range of this study.
