Ventilation Strategy for Acceptable PM2.5 in a Classroom Depending on Building Characteristics

다국어 초록 (Multilingual Abstract)

Recently, outdoor particulate matters have become a serious problem in Korea. Pollutants exhausted from industrial plants and dust transported from adjacent regions contribute to the peaks in fine particle concentration. Indoor air quality is affected by ambient air pollution. Common methods for maintaining good IAQ from harmful outdoor particles are either through the usage of an air purifier (AP) or to install a filter in the heat recovery ventilator (HRV)system. The purpose of this study is to investigate appropriate ventilation strategy to maintain good IAQ by combining operations of AP, HRV and window opening depending on outdoor particulate concentrations and temperature conditions in a classroom. Result shows natural ventilation can operate when the outdoor temperature in the range 22-30 ℃ and the outdoor PM2.5 concentrations below 30μg/m3.
