摘要：Atmospheric particle resuspension caused by supply air deposited on the surface of duct is the main process for generating particulate contaminates in indoor air. Forces acting on the particle were analyzed. Force/moment balance model was used to analyzing the resuspension process. Applied Mortazavi modified model, integrated with atmospheric particle size distribution, polydisperse particle resuspension model was established. The results show that the dimension less force of larger particle is smaller and it is easer to resuspend. Resuspension mass from cooling coil Surface is much larger than from duct and should be pay more attention.
