신축공동주택에서 플러쉬아웃 실시에 따른 실내 VOCs 농도저감 효과에 관한 연구

Abstract

본 연구에서는 신축 공동주택을 대상으로 플러쉬아웃  실시 전과 후의 VOCs 농도를 정량적으로 분석하고 실내 오염물질 저감 효과를 확인하였다. 플러쉬아웃 시행 후에는 TVOC와 개별 VOCs 모두 실내 농도가 감쇠되는 것으로 나타났으며 그 저감울은 각각 63%~87%와 50%~92%의 범위로 조사되었다. 또한 플러쉬아웃과 베이크아웃의 실내 VOCs농도 저감효과를 비교한 결과 베이크아웃과 유사한 정도의 실내 오염물질 저감 효과가 있음을 확인하였다. 추후에는 다양한 플러쉬아웃 조건에서의 측정이 필요할 것으로 판단된다. The purpose of this study was to confirm the effects of flush-out on the reduction of Volatile Organic Compounds(VOCs) concentration innewly built residential buildings. The field measurements were conducted in two complexes of multi-residential buildings which are locatedsuburban areas of Seoul. About three samples of residential buildings were selected in the field measurements. Two samples, B and C, hadbeen flush-out with outdoor air more than seven days. The sample A was maintained at same condition during the flush-out because of thecomparison. The indoor concentrations of VOCs in the three samples were measured at three times, before, during ,and after flush-out. Fromthe field measurements, it was confirmed that two samples’ indoor VOCs’ concentrations were considerably decreased after the flush-outcomapred with those of the sample A in which the flush-out was not conducted. The decreases of indoor VOCs concentrations werecorresponding to about 50% ~ 92% of the concentrations of before. Through the reviews for the previous studies, it was also found that thereduction effects of the flush-out is similar with the those of the bake-out which were reported in the previous studies.
