Floor Plenum Ventilation

A plenum space is a part of a building that can facilitate air circulation for heating and air conditioning systems by providing pathways for either heated conditioned or return airflows usually at greater than atmospheric pressure.

Floor plenum ventilation.

Underfloor air distribution ufad is an air distribution strategy for providing ventilation and space conditioning in buildings as part of the design of a hvac system. A building s mechanical ventilation system can run on 100 outside air. Plenum ventilation definition a system of mechanical ventilation in which fresh air is forced into the spaces to be ventilated from a chamber plenum chamber at a pressure slightly higher than atmospheric pressure so as to expel foul air. Plenum ventilation in buildings designing buildings wiki share your construction industry knowledge.

However some drop ceiling designs create a. Airfixture s underfloor air distribution system takes advantage of pressurized underfloor plenum spaces to provide air conditioning heating and ventilation. Sound transmission between adjacent rooms with floor diffusers served by the same plenum is sometimes cited as a concern. Space between the structural ceiling and the dropped ceiling or under a raised floor is typically considered plenum.

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. 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. This reduces the energy.
