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 entails a reconfiguration of a plenum serving as an air collector supplying numerous air handling units . These provide the air supply for fire safety systems . EOLIOS engineering studies have made it possible to compare the different levels of pressure drops according to the different variants imagined by the architects.
For this, the entire plenum was modeled from on-site quotations. The air intake grilles were under-modeled from technical data sheets provided by the manufacturer.
In the end, the studies made it possible to rule out the configurations degrading the performance of the plenum in order to ensure that the configurations retained remained in conformity with the fire safety requirements.
