The purpose of this study is to investigate effective ventilation methods to maintain comfortable indoor air quality in Childcare Centers. The variations of Temperture, Relative Humidity and indoor air pollutants (Carbon dioxide, Particulate matter, Formaldehyde, Total volatile organic compunds) were measured 1.0~1.2m above the floor in teaching room and recreation room. Temperature, humidity and CO2 were measured 30times(1min/time) and PM10 was measured 10times (3min/time). Formaldehyde and volatile organic compounds were measured and analyzed based on The Indoor Air Quality Official Test Method. The measurements performed in teaching room, recreation room and outdoor. The concentration of PM10 and TVOC exceeded the standard and the concentration of CO2 and HCHO were below the standard. And It was found that nursing rooms should be ventilated than recreation rooms |
