This study targeted school sports facilities with general area and ventilation system and measured the changes in PM10 concentration according to students’ activities, analyzed the amount of fine dust generated, and simulated the efficiency of fine dust reduction according to the ventilation method. According to the study, the PM10 reduction efficiency compared to without ventilation[C-1] was 34% in operating EHP[C-2] when PM10 alarm is good, 24% in [C-2] when PM10 alarm is normal, 16% in [C-2] when PM10 alarm is bad, 26% in opening window[C-3] when PM10 alarm is good, and 0% in [C-3] when PM10 alarm is normal, bad. In case of installed HEPA filter in EHP[C-4] reduction efficiency was 34% when PM10 alarm is good, 28% when PM10 alarm is normal, 22% when PM10 alarm is bad. In sided ventilation[C-5], the PM10 reduction efficiency was 53% when PM10 alarm is good, 48% when PM10 alarm is normal, and 41% when PM10 alarm is bad. As a result, Sided ventilation[C-5] installed close to generate factor was the most suitable ventilation system. |
