Abstract
There are many difficulties in removing the high concentration of fine dust flowing into the building. In order to reduce the concentration of fine dust by 30% according to a government policy, it is tried to install a waste transport pipeline inside the building and remove fine dust through air suction. Flow simulation has been performed to investigate the flow characteristics of fine dust inside the building. Throughout an empirical study on the installation of air conditioners and waste transport pipelines in buildings, it is found that vacuum inhalation of the waste transport pipeline can reduce the ultrafine dust to 63.2% and fine dust to 62.8% while the building
