   en.wikipedia.org/wiki/Blower_door

   Fan airflow is determined using C Fan and n Fan values that are provided by the blower door manufacturer, and they are used to calculate Q Fan. The multi-point blower door test procedure results in a series of known values of Q n, Fan and ∆P n, Building. Typical ∆P n, Building values are ±5, 10, 20, 30, 40 and 50 pascal.

5. Room air distribution - Wikipedia

   en.wikipedia.org/wiki/Room_air_distribution

   Displacement ventilation systems supply air directly to the occupied zone.The air is supplied at low velocities to cause minimal induction and mixing. This system is used for ventilation and cooling of large high spaces, such as auditorium and atria, where energy may be saved if only the occupied zone is treated rather than trying to control the conditions in the entire space.

6. 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).

7. Airflow - Wikipedia

   en.wikipedia.org/wiki/Airflow

   Mechanical ventilation uses fans to induce flow of air into and through a building. Duct configuration and assembly affect air flow rates through the system. Dampers, valves, joints and other geometrical or material changes within a duct can lead to flow pressure (energy) losses. [2]
