Underfloor Air Distribution Systems (UFAD) are rapidly penetrated the office building arena across the world because they provide a number of advantages, (and a few disadvantages) over conventional office building HVAC systems. This brochure will present current and new design approaches and new solutions that refine and improve the performance and flexibility of (UFAD) systems. Included in this brochure are explanations of maintenance of uniform supply temperatures in the underfloor plenum, introduction of thermal stratification in the occupied spaces, product and design applications of leakage issues in the floor plenum, control of space humidity for humid climates.

The Green Building Council supports underfloor design and applications for improved indoor air quality and reduced energy.

Under-Floor Air Distribution (VAV / UFAD), compared with the ceiling air supply system
Air conditioned at (IP 60 F to 65 F, Sl 16-18 C) supplied directly from a central located floor air handler unit to the under floor and as a plenum air is distributes up throughout floor and diffused in a swirling air mixing distribution action. Channeling supply air under the floor is accomplished with zone units and pressure modulation controlled dampers for variable a distribution. UFAD have excellent zoning of large spaces at different air and temperature conditions with standard underfloor diffusers. Supply air swirl motion mixes and increases the comfort and IAQ levels. Ceiling systems blow air down and can not mix properly low air flow.

Underfloor air supply systems include, but are not limited to the following advantages.
♦ Reduce building construction costs
♦ Reduce direct cost of initial installation and reduce operating costs
♦ Energy saving are direct from less of a heating load to operate UFAD
♦ Excellent airflow patterns
♦ Forgiving tenant improvement system flexibility
♦ LEED points and “Green Design”, to create a comfortable environment

Under-floor air supply systems Applications
Under-floor air supply systems applications are suitable for office buildings. with an open floor office layout each diffusers can allow the occupant to adjust the air supply terminal according to individual needs, and to meet single zones that need independent control and environmental control.

RSV-UFD Floor Air Swirl Diffuser
Royal floor air swirl diffusers set flush with the ground, through the air swirl diffusers swirl discharge, rapid induction of the surrounding air and the occurrence of heat and moisture transfer, lighter warm air slowly rises to near the ceiling, the entire room air forming a layered. That indoor air distribution from floor to ceiling next sent back airflow pattern, the formation of different local climate. Since the ground-mounted air conditioning system directly into staff activities area, so the supply air temperature and humidity requirements are higher than conventional ceiling air supply, to avoid the discomfort of cold wind blowing straight. Royal air conditioning full account of the ground-mounted system air blowing mode, by accurate temperature and humidity control, with swirl difusers achieve a high level of interior comfort. Achieve traditional air conditioning, particularly suited to retrofit buildings and renovation of existing buildings.
