2. High-volume low-speed fan - Wikipedia

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

   A High-volume low-speed fan. A high-volume low-speed (HVLS) fan is a type of mechanical fan greater than 7 feet (2.1 m) in diameter. [1] HVLS fans are generally ceiling fans although some are pole mounted. HVLS fans move slowly and distribute large amounts of air at low rotational speed– hence the name "high volume, low speed."

3. Ceiling fan - Wikipedia

   en.wikipedia.org/wiki/Ceiling_fan

   A pendulum fan or flap fan is a type of low velocity ceiling fan that can be used for air circulation around a targeted area. The back and forth motion increases turbulence around cooling sources, like chilled waterfalls at the Lavin Bernick Center at Tulane, helping to cool a greater volume of air. Brushed DC ceiling fans.

4. Quiet PC - Wikipedia

   en.wikipedia.org/wiki/Quiet_PC

   A 120 mm variable speed fan. If they use fans at all, quiet PCs typically use larger-than-usual low-speed fans with quiet-running motors and bearings. The 120 mm size is common, and 140 mm fans are used where cases or heat sinks allow them. Quiet fan manufacturers include Nexus, EBM-Papst, [30] Yate Loon, Scythe, [31] and Noctua. [32]

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. Fan (machine) - Wikipedia

   en.wikipedia.org/wiki/Fan_(machine)

   An axial box fan for cooling electrical equipment. Axial-flow fans have blades that force air to move parallel to the shaft about which the blades rotate. This type of fan is used in a wide variety of applications, ranging from small cooling fans for electronics to the giant fans used in cooling towers. Axial flow fans are applied in air ...

7. Evaporative cooler - Wikipedia

   en.wikipedia.org/wiki/Evaporative_cooler

   Air is moved by a centrifugal fan or blower (usually driven by an electric motor with pulleys known as "sheaves" in HVAC terminology, or a direct-driven axial fan), and a water pump is used to wet the evaporative cooling pads. The cooling units can be mounted on the roof (down draft, or downflow) or exterior walls or windows (side draft, or ...
