Effect Analysis of Particle Deposition in Ventilation Duct of Air Condition System

Yunlong Han

Abstract

Particle deposition in ventilation duct can decrease the performance of air conditioning system and impact the indoor air quality.It is important to investigate the mechanism of the flow and deposition of dust in different duct configuration because these understandings are useful for duct cleaning and taking measures to decrease particle deposition.The parameters of particle deposition in duct such as particle diameter,air velocity and duct roughness were discussed in this paper besides the further reached problems were put forward.
