2. Heating, ventilation, and air conditioning - Wikipedia

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

   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 very critical to maintaining a proper temperature.

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

4. 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 ...

5. 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 ...

6. 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.

7. 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 ...
