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 surveyed the particle removal systems in order to develop the new system of particle removing can be adopted in the current AHU of subway station.

Management of indoor air quality of underground subway station is an important issue. The air handling unit (AHU) installed in the underground subway station is the main facility determining the air quality of station. Especially for removing particulate matters, it is important to operate the appropriate air filter. However, there is no quantitative test method for existing air filter in site. It is rarely known that the collection efficiency of air filter can satisfy the designed criteria or not. In this study, we set the reference method using the mini-volume air sampler inside the AHU to evaluate the collection efficiency of different types of air filters. In addition, we applied the portable instrument based on the light-scattering method to the efficiency test. The method we applied in this study can be used in the evaluation of air filter in site.

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.
