School classrooms are places where students, who are health-sensitive, spend a lot of time in a day, so particulate matter (PM) in classrooms has a significant influence on students" health. The PM concentration in school classrooms can be formed from both the penetration from the outside air and the generation/resuspension of the indoor students" activities. Previous studies conducted a macroscopic analysis of the indoor PM concentration based on occupancy status, however, the indoor PM penetration and generation characteristics may change every minute depending on the student"s activity and ventilation status.
The aims of this study is to predict the PM concentration in the classroom by quantifying the penetration from the outside air and the generation from indoor activities according to the school occupancy schedule. Long-term measurements for PM concentration were conducted for about four months in 5 classrooms. The results showed that the inflow of external PM tends to decrease as the particle diameter increases when the door/window is closed. However, when students move through the door, the inflow of external PM with large particle size increased. Besides, the indoor PM generation rate increases as the particle diameter increases and particles with a diameter of 3 μm or more were generated by the student activities. Lastly, on days when the outside PM concentration was high, the indoor PM concentration was also high due to not only the infiltration effect, but also students entering and exiting.
