The basic arrangement in a plenum floor is that the floor is supported above the slab to leave space below for the heating plenum and utilities.
Floor plenum design.
It is important that conditioned air in a floor plenum flows into the occupied zone and does not leak into cavities risers stairwells heating trenches or other adjacent zones.
Within the underfloor plenum it is always desirable to the extent possible to have the supply air flow freely to the supply outlets.
A floor plenum is a void between a building s floor structure and a raised access floor used for distributing conditioned air to the spaces above.
Plenum ventilation in buildings designing buildings wiki share your construction industry knowledge.
The source of heat is the downflow or counterflow warm air furnace commonly used to force air into under slab ductwork.
Plenum contents can have a major impact on the raised floor plenum performance.
During the pre design phase the contents and their impact should be conceptually identified.
Warm air from ducts is discharged into the underflow plenum rather than directly.
Plenums are air compartments or chambers that are sometimes found in buildings either above suspended ceilings in the gap between the ceiling and the floor slab or below raised floors in the gap between the raised floor and the floor slab.
Airfixture s underfloor air distribution system takes advantage of pressurized underfloor plenum spaces to provide air conditioning heating and ventilation.
Plenum space air conditioning heating and ventilation.
