| Abstract: | Based on the design of smoke prevention by the increasing pressure,the fan pressure-head,the absolute roughness of the inner side of the duct,the ratio of length-width and the wind velocity in vertical duct section,the fan characteristics and some other issues in the design of smoke prevention by the increasing pressure,this paper puts forward measures for the design of the system.to provide some reference for the design of smoke prevention by the increasing pressure. |
