Abstract

Airtightness of modern buildings has been increased and people are staying indoors about 20 hours a day. As indoor residence time increase, effect of indoor air quality on health got higher. Deposition rate and penetration factor are important factors for predicting indoor particle concentration. However, these values can be determined differently during analyzing process. In this paper uncertainty of determining deposition rate and penetration factor that comes from entering different input data is experimentally examined. As a result, deposition rate got higher as particle size increase and penetration factor got lower as particle size increase, but these value could be changed as input data changes even if experiment was passed off in same place. For calculating correct deposition rate and penetration factor, standard for setting input data has to be established and experiment has to be repeated many times.
