2. Damper (flow) - Wikipedia

   en.wikipedia.org/wiki/Damper_(flow)

   A damper is a valve or plate that stops or regulates the flow of air inside a duct, chimney, VAV box, air handler, or other air-handling equipment. A damper may be used to cut off central air conditioning (heating or cooling) to an unused room, or to regulate it for room-by-room temperature and climate control - for example, in the case of ...

3. Air-mixing plenum - Wikipedia

   en.wikipedia.org/wiki/Air-mixing_plenum

   The mix of fresh air and recirculated air can thus be adjusted to suit the needs of the building's occupants. Most systems will use motorized dampers to control the air mixing, and controlled by the building management system (BMS), or controls system. Typically as the fresh air and exhaust air dampers are driven from 0% open to 100% open, the ...

4. Industrial fan - Wikipedia

   en.wikipedia.org/wiki/Industrial_fan

   Industrial Dampers - These devices also allow fan volumetric flow control during operation, by means of panels so as to direct gas flow or restrict the inlet or outlet areas. There is a variety of dampers available: Louvered Inlet Box Dampers Radial Inlet Dampers Variable Inlet Vane (VIV) Dampers Vortex Dampers Discharge Dampers

5. HVAC control system - Wikipedia

   en.wikipedia.org/wiki/HVAC_control_system

   HVAC (Heating, Ventilation and Air Conditioning) equipment needs a control system to regulate the operation of a heating and/or air conditioning system. [1] Usually a sensing device is used to compare the actual state (e.g. temperature) with a target state. Then the control system draws a conclusion what action has to be taken (e.g. start the ...

6. Fire damper - Wikipedia

   en.wikipedia.org/wiki/Fire_damper

   Air transfer fire dampers for doors are designed and tested for use in the lower part of door leaves and cannot be installed elsewhere or higher. In Europe, the fire door test EN 14600 and EN 1634-1 applies. Air transfer fire dampers in facades are vents applied in wall, eave soffit, gable or foundation. In the US, these are used to protect ...

7. Centrifugal fan - Wikipedia

   en.wikipedia.org/wiki/Centrifugal_fan

   Compared to standard axial fans, they can provide similar air movement from a smaller fan package, and overcome higher resistance in air streams. [2] Centrifugal fans use the kinetic energy of the impellers to move the air stream, which in turn moves against the resistance caused by ducts, dampers and other components. Centrifugal fans displace ...
