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. Zone valve - Wikipedia

   en.wikipedia.org/wiki/Zone_valve

   A zone valve is a specific type of valve used to control the flow of water or steam in a hydronic heating or cooling system. In the interest of improving efficiency and occupant comfort, such systems are commonly divided up into multiple zones. [ 1 ]

4. Variable air volume - Wikipedia

   en.wikipedia.org/wiki/Variable_air_volume

   The air blower's flow rate is variable. For a single VAV air handler that serves multiple thermal zones, the flow rate to each zone must be varied as well. Simple VAV terminal unit. A VAV terminal unit, [9] often called a VAV box, is the zone-level flow control device. It is basically a calibrated air damper with an automatic actuator. The VAV ...

5. Duct (flow) - Wikipedia

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

   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.

6. Shock absorber - Wikipedia

   en.wikipedia.org/wiki/Shock_absorber

   A shock absorber or damper is a mechanical or hydraulic device designed to absorb and damp shock impulses. It does this by converting the kinetic energy of the shock into another form of energy (typically heat) which is then dissipated. Most shock absorbers are a form of dashpot (a damper which resists motion via viscous friction).
