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.
Plenum ventilation in buildings designing buildings wiki share your construction industry knowledge.
One of the main advantages of this setup is that plenum air supplies require less fan power to distribute air than through ducts improving efficiency and thus requiring less.
The source of heat is the downflow or counterflow warm air furnace commonly used to force air into under slab ductwork.
Warm air from ducts is discharged into the underflow plenum rather than directly.
Within the underfloor plenum it is always desirable to the extent possible to have the supply air flow freely to the supply outlets.
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.
The following list of questions is a good place to start in this process.
Plenum space air conditioning heating and ventilation.
Airfixture s underfloor air distribution system takes advantage of pressurized underfloor plenum spaces to provide air conditioning heating and ventilation.
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.
During the pre design phase the contents and their impact should be conceptually identified.
