The results showed when the particle sizes were less than 1.0 μm, the deposition rate was decreased from the increased in particle sizes. When the particle sizes were larger than 1.0 μm, the deposition rate was in-creased from the increased in particle sizes. A higher inlet velocity resulted in a greater deposition rate. High humidity or low temperature would also lead to a high deposition rate of dust. The results given in this paper are helpful for optimization of the fresh air system.
