Abstract

A bake-out process using auto switchgear for five days was performed to evaluate the reduction effect of the concentration of volatile organic compounds (VOCs) and formaldehyde in a newly-built elementary school gymnasium. Reduction rates of VOCs were observed as followings: 38.2, 64.2, 86.3, 80.2, and 71.5% for benzene, toluene, ethylbenzene, xylene, and styrene, respectively, which satisfies the indoor air quality standards of newly-built apartment houses in Korea. The reduction rate of total VOCs and formaldehyde were 67.0 and 24.7%, respectively. Those results proved that the bake-out process using auto switchgear was effective for reducing indoor air pollutants.

초등학교의 신축된 실내체육관을 대상으로 자동 개폐장치를 이용하여 실내의 휘발성유기화합물 및 포름알데히드 농도 저감효과를 평가하기 위하여 5일간 베이크 아웃을 진행하였다. 베이크 아웃을 실시한 결과 베이크 아웃 실시 전의 농도에 비해 벤젠의 경우 38.2%, 톨루엔은 64.2%, 에틸벤젠은 86.3%, 자일렌은 80.2%, 스티렌은 71.5%의 저감률을 보였으며, 환경부의 신축공동주택의 실내공기질 기준치를 만족하는 것으로 나타났다. 총휘발성유기화합물의 저감률은 67.0%이었으며 포름알데히드의 경우 24.7%의 저감률을 보여 자동 개폐장치를 이용한 베이크 아웃이 실내오염물질을 제거하는 데 유용함을 확인하였으며, 자동 베이크 아웃 시스템을 이용할 경우 효과적인 베이크 아웃이 가능함을 확인하였다.
