초미세먼지를 이용한 오피스 내 환기유동에 대한 실험적 연구

다국어 초록 (Multilingual Abstract)

Due to the recent COVID-19 situation, the importance of indoor ventilation has been highlighted. In particular, ventilation in residential and work spaces where most of the day is spent is important. In this study, ventilation performance was experimentally studied by measuring the concentration of ultrafine particulate matters (PM2.5) according to the opening conditions of windows and door for an office model in the wind tunnel. Furthermore, in order to find out the cause of the difference in ventilation performance, a quantitative analysis of the internal flow structure of the office model was performed through particle image velocimetry (PIV). As the opening angle of window increased, the mean velocity inside the model increased and the ventilation performance is also enhanced. In particular, the opening condition of door had a great effect on the ventilation performance in the office model. It is expected that this study would provide a guideline that can effectively improve ventilation performance in indoor space.
