2. Damper (flow) - Wikipedia

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

   A zone damper (also known as a Volume Control Damper or VCD) is a specific type of damper used to control the flow of air in an HVAC heating or cooling system. In order to improve efficiency and occupant comfort, HVAC systems are commonly divided up into multiple zones.

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.

4. Turning vanes (HVAC) - Wikipedia

   en.wikipedia.org/wiki/Turning_vanes_(HVAC)

   HVAC turning vanes are sheet metal devices inside of mechanical ductwork used to smoothly direct air inside a duct where there is a change in direction, by reducing resistance and turbulence. See also [ edit ]

5. HVAC control system - Wikipedia

   en.wikipedia.org/wiki/HVAC_control_system

   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. 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 blower).

6. Heating, ventilation, and air conditioning - Wikipedia

   en.wikipedia.org/wiki/Heating,_ventilation,_and...

   Overview The three major functions of heating, ventilation, and air conditioning are interrelated, especially with the need to provide thermal comfort and acceptable indoor air quality within reasonable installation, operation, and maintenance costs. HVAC systems can be used in both domestic and commercial environments.

7. Fire damper - Wikipedia

   en.wikipedia.org/wiki/Fire_damper

   Fire dampers can also close following receipt of an electrical signal from a fire alarm system utilising detectors remote from the damper, indicating the sensing of heat or smoke in the building occupied spaces or in the HVAC duct system.

8. Air handler - Wikipedia

   en.wikipedia.org/wiki/Air_handler

   An air handler, or air handling unit (often abbreviated to AHU ), is a device used to regulate and circulate air as part of a heating, ventilating, and air-conditioning ( HVAC) system. [1] An air handler is usually a large metal box containing a blower, furnace or A/C elements, filter racks or chambers, sound attenuators, and dampers. [2] Air handlers usually connect to a ductwork ventilation ...

9. Duct (flow) - Wikipedia

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

   Volume control dampers An opposed-blade, motor-operated zone damper, shown in the "open" position. Ducting systems must often provide a method of adjusting the volume of air flow to various parts of the system. Volume control dampers (VCDs; not to be confused with smoke/fire dampers) provide this function.
