다기능 환기 유닛의 실내 VOCs 제거 성능에 관한 연구

The objective of this study is to examine the efficiency of a multi-ventilation unit for the removal of VOCs(Volatile Organic Compounds). A full-scale mock-up chamber was used to perform experiments. Toluene and formaldehyde were used to control the concentration of pollutants in the chamber. Ventilation was operated by three methods; filtering without ventilation, ventilation without filtering, and the combination of filtering without ventilation and the ventilation without filtering. The best efficiency was achieved by the ventilation method that used the combination. The efficiency of removing the pollutants became greater as the concentration of the pollutants in the chamber increased.
