2. Damper (flow) - Wikipedia

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

   This damper can switch the electrical power to control additional "slave" dampers, minimizing the electrical load on the damper's control circuitry and power transformer. 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 ...

3. Backdraft - Wikipedia

   en.wikipedia.org/wiki/Backdraft

   A backdraft (North American English), backdraught (British English) [1] or smoke explosion is the abrupt burning of superheated gases in a fire caused when oxygen rapidly enters a hot, oxygen-depleted environment; for example, when a window or door to an enclosed space is opened or broken. Backdrafts are typically seen as a blast of smoke and ...

4. Stack effect - Wikipedia

   en.wikipedia.org/wiki/Stack_effect

   The stack effect or chimney effect is the movement of air into and out of buildings through unsealed openings, chimneys, flue-gas stacks, or other purposefully designed openings or containers, resulting from air buoyancy.

5. Industrial furnace - Wikipedia

   en.wikipedia.org/wiki/Industrial_furnace

   The stack damper contained within works like a butterfly valve and regulates draft (pressure difference between air intake and air exit) in the furnace, which is what pulls the flue gas through the convection section. The stack damper also regulates the heat lost through the stack.

6. Register (air and heating) - Wikipedia

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

   Dampers can also help adjust a HVAC system for seasonal use. [7] During winter months, for example, an air conditioning register can be closed to prevent cold air from being pulled from the room. This allows the hot air to mix more completely with the cold air in the room, improving the efficiency of the HVAC system. [ 7 ] (

7. Wood-burning stove - Wikipedia

   en.wikipedia.org/wiki/Wood-burning_stove

   The dampers can usually be accessed by turning knobs or handles attached to the damper. Some stoves adjust their own airflow using mechanical or electronic thermostatic devices. The highest heating efficiencies on closed appliances can be attained by controlling the various supplies of air to the stove (operating the air controls correctly).
