3. Underfloor air distribution - Wikipedia

   en.wikipedia.org/wiki/Underfloor_air_distribution

   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. UFAD systems use an underfloor supply plenum located between the structural concrete slab and a raised floor system to supply conditioned air to supply outlets (usually floor ...

4. High-volume low-speed fan - Wikipedia

   en.wikipedia.org/wiki/High-volume_low-speed_fan

   This column of air moves down and out along the floor. Called a horizontal floor jet, this deep wall of horizontal moving air is relative to the diameter of a fan, and to a lesser degree, the speed of a fan. Once the floor jet reaches its potential, it migrates outward until it meets a side wall or other vertical surface. [8]

5. Displacement ventilation - Wikipedia

   en.wikipedia.org/wiki/Displacement_ventilation

   Displacement ventilation is best suited for taller spaces (higher than 3 meters [10 feet]). [2] Standard mixing ventilation may be better suited for smaller spaces where air quality is not as great a concern, such as single-occupant offices, and where the room height is not tall (e.g., lower than 2.3 meters [7.5 feet]).

6. Heating, ventilation, and air conditioning - Wikipedia

   Air-side economizers also use outside air to condition spaces, but do so using fans, ducts, dampers, and control systems to introduce and distribute cool outdoor air when appropriate. An important component of natural ventilation is air change rate or air changes per hour : the hourly rate of ventilation divided by the volume of the space.

7. Centrifugal fan - Wikipedia

   en.wikipedia.org/wiki/Centrifugal_fan

   A centrifugal fan is a mechanical device for moving air or other gases in a direction at an angle to the incoming fluid. Centrifugal fans often contain a ducted housing to direct outgoing air in a specific direction or across a heat sink; such a fan is also called a blower, blower fan, or squirrel-cage fan (because it looks like a hamster wheel).
