Underfloor air distribution is an air distribution strategy for offering air flow and space conditioning in buildings as part of the design of a HVAC system. UFAD methods use an underfloor supply plenum positioned between the structural concrete slab and a raised flooring system to provide conditioned air through flooring diffusers immediately into the occupied zone of the building. UFAD methods are much like standard overhead methods when it comes to the forms of gear used at the cooling and heating crops and primary air-dealing with models .
