The purpose of this study is to find the effect of various operation schedule of ventilation on IAQ by measuring CO2, PM10, TVOCs, and HCHO. As a result of the indoor air quality measurement, increase of the operation time showed a significant reduction in CO2 concentration. However, as the operation time period changed from morning, evening, and night with 2hours the reduction did not show a significant effect on reducing CO2 concentration. The operation of ventilation system did not had any effect on PM10 as the operation time increased, and the operation time period changed. The operation of ventilation system lowered the TVOCs and HCHO concentration, however the reduction of the concentration did not had a significance difference as the operation time increased. Finally the operation of the ventilation decreased CO2, TVOCs, HCHO concentration, but did not had a significance effect on PM10. |
