G-2 Development of High-Efficient Air Purification System with Photocatalyst (Part 2) : Study on the Effect of Chemical Removal-Efficiency from PCO Unit Structure and Velocity

Abstract

The purpose of this study is to development the high-efficient air purification system with photocatalyst. This paper presents the relations between the chemical removal-efficiency and PCO unit structure or air velocity. It was found using CFD simulation that the most efficient unit among the cases considered had a structure like a chamber. And PCO unit works efficiently with comparatively low air velocity of 0.1m/s. There is room for consideration, as air-conditioning systems need higher air velocity.
