공동주택의 기계환기 급기 덕트내 분진비산에 관한 연구

Abstract

The object of t6his study was to quantify the particle resuspension from the supply air ducts in residential buildings in whichmechanical ventilation fan was intermittently operated after build, and also to analyze the effects of the resuspesion on indoor airparticle concentrations. Fifteen sample apartments was selected for the field study from three sites located in south metropolitanarea of Seoul. From the results of the field study, it was found that particle resuspension in supply duct occurred in mostapartments. The indoor particle concentration was rapidly increased at the first moment of the fan operation, and then slowlydecreased according to the ventilation and filtration.
