싸이클론 패널방식의 신개념 공조기 에어필터 개발

Particulate matter (PM) is one of the major indoor air pollutants especially in the subway station in Korea. In order to remove PM in the subway station, several kinds of PM removal system such as roll-filter, auto-washable air filter, demister, and electrostatic precipitator are used in the air handling unit (AHU) of subway station. However, those systems are faced to operation and maintenance problems since the filter-regeneration unit consisting of electrical or water jet parts is malfunctioned due to the high load of particulates and the filter material needs periodic replacement. In this study, we presented the novel air filtration system utilizing cyclone panels for removing PM in AHU. The system was designed based on numerical simulation test in terms of particle collection efficiency and pressure drop. The mock-up model was manufactured for experimental test and the results showed good feasibility.
