2. Damper (flow) - Wikipedia

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

   Damper (flow) Opposed blade dampers in a mixing duct. 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 ...

3. Air handler - Wikipedia

   en.wikipedia.org/wiki/Air_handler

   Air handler. An air handling unit; air flow is from the right to left in this case. Some AHU components shown are. 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 ...

4. Heating, ventilation, and air conditioning - Wikipedia

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

   This allows a more granular application of heat, similar to non-central heating systems. Zones are controlled by multiple thermostats. In water heating systems the thermostats control zone valves, and in forced air systems they control zone dampers inside the vents which selectively block the flow of air. In this case, the control system is ...

5. Variable air volume - Wikipedia

   en.wikipedia.org/wiki/Variable_air_volume

   Variable air volume ( VAV) is a type of heating, ventilating, and/or air-conditioning ( HVAC) system. Unlike constant air volume (CAV) systems, which supply a constant airflow at a variable temperature, VAV systems vary the airflow at a constant or varying temperature. [1] [2] The advantages of VAV systems over constant-volume systems include ...

6. Zone valve - Wikipedia

   en.wikipedia.org/wiki/Zone_valve

   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] For example, in a house, the main floor may be served by one heating zone while the ...

7. 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.
