Field Evaluation of Newly-developed Panel-cyclone System for Air Handling Unit (AHU) of Subway Station

초록

Particulate matter (PM) is one of the major indoor air pollutants especially in the underground facilities, such as subway station and complex shopping mall. In order to remove PM in the subway station, several kinds of PM removal system such as medium filter, auto suction filter, auto washing filter and electrostatic precipitator are used in the air handling unit (AHU) of subway stations. However, those systems are prone to operation and maintenance problems since the filter-regeneration unit consisting of electrical or water jet parts might malfunction due to the high load of particulates unless the filter medium is periodically replaced. In this study, we suggested axial-flow cyclone system with minimized maintenance requirement comparing to above mentioned method.
