Floor Plenum Design

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.

Floor plenum design.

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. Within the underfloor plenum it is always desirable to the extent possible to have the supply air flow freely to the supply outlets. Plenum ventilation in buildings designing buildings wiki share your construction industry knowledge. 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 source of heat is the downflow or counterflow warm air furnace commonly used to force air into under slab ductwork. Plenum space air conditioning heating and ventilation. During the pre design phase the contents and their impact should be conceptually identified. Airfixture s underfloor air distribution system takes advantage of pressurized underfloor plenum spaces to provide air conditioning heating and ventilation.

Plenum contents can have a major impact on the raised floor plenum performance. The number of plenum inlet locations is a function of the size of control zones access points available in the building amount of distribution ductwork used under the floor and other design issues. 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.
