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. 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 ...

4. Fire damper - Wikipedia

   en.wikipedia.org/wiki/Fire_damper

   Fire damper. Interior of German mechanical fire damper inside of a galvanised steel duct. Fire dampers (or fire shutters) are passive fire protection products used in heating, ventilation, and air conditioning (HVAC) ducts to prevent and isolate the spread of fire inside the ductwork through fire-resistance rated walls and floors. [1]

5. Duct (flow) - Wikipedia

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

   These dampers may be manual or automatic. Zone dampers provide automatic control in simple systems while variable air volume (VAV) allows control in sophisticated systems. Smoke and fire dampers. Smoke dampers and fire dampers are found in ductwork where the duct passes through a firewall or firecurtain. Smoke dampers are driven by a motor ...

6. Register (air and heating) - Wikipedia

   en.wikipedia.org/wiki/Register_(air_and_heating)

   A floor register. A register is a grille with moving parts, capable of being opened and closed and the air flow directed, which is part of a building's heating, ventilation, and air conditioning (HVAC) system. The placement and size of registers is critical to HVAC efficiency. Register dampers are also important, and can serve a safety function.

7. Air-mixing plenum - Wikipedia

   en.wikipedia.org/wiki/Air-mixing_plenum

   The mixing plenum normally combines two air streams, and includes for three sets of dampers: one for the fresh air, one for the exhaust air, and a mixing damper between the two air streams. [2] 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 ...

8. Heating, ventilation, and air conditioning - Wikipedia

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

   In the lower middle is the capacitor. Heating, ventilation, and air conditioning ( HVAC) [1] is the use of various technologies to control the temperature, humidity, and purity of the air in an enclosed space. Its goal is to provide thermal comfort and acceptable indoor air quality.

9. Fan coil unit - Wikipedia

   en.wikipedia.org/wiki/Fan_coil_unit

   The thermostat controls the fan speed and/or the flow of water or refrigerant to the heat exchanger using a control valve. Due to their simplicity, flexibility, and easy maintenance, fan coil units can be more economical to install than ducted 100% fresh air systems (VAV) or central heating systems with air handling units or chilled beams. FCUs ...
