겨울철 침기에 따른 실내·외 미세먼지 농도 관계에 관한 연구

다국어 초록 (Multilingual Abstract)

Penetration of outdoor particulate matter(PM) is caused by the air flow from outside through infiltration, natural ventilation and mechanical ventilation. Therefore, recent deterioration of air pollution can increase the possibility of penetration of outdoor PM indoors. In this study, indoor and outdoor size-resolved particle concentrations and the ratio under infiltration condition are analyzed to investigate the impact of particle size on the penetration and formation of indoor PM concentration. The particle number concentrations for PM0.3, 0.5, 1, 3, 5, 10㎛ were measured using optical particle counter(OPC) and ratio of indoor-to-outdoor(I/O) particle concentrations were calculated. Results suggested that outdoor PM could penetrate through outdoor airflow by infiltration and contribute to increase indoor PM concentrations. Calculated I/O ratio depended strongly on particle size. I/O ratio of small size particles (<0.5㎛) were around 1, and as the particle size increases, the I/O ratio tend to be decreased.
