EOLIOS Engineering provided an overview of pressure drops in a plenum in relation to fire safety systems.
Smoke extraction engineering
The major restructuring of office buildings in La Défense has led to the reconfiguration of a plenum serving as aeraulic collector supplying many AHUs . These ensure the air supply to fire safety systems. The EOLIOS engineering studies made it possible to compare the different levels of pressure drops according to the different variants imagined by the architects.
To do this, the entire plenum has been remodeled from on-site quotations. The air intake grilles have been under-modeled from technical data sheets provided by the manufacturer.
Finally, the studies made it possible to rule out the configurations that deteriorate the performance of the plenum in order to ensure that the configurations selected remained in compliance with fire safety requirements.
