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. Variable air volume - Wikipedia

   en.wikipedia.org/wiki/Variable_air_volume

   It is basically a calibrated air damper with an automatic actuator. The VAV terminal unit is connected to either a local or a central control system. Historically, pneumatic control was commonplace, but electronic direct digital control systems are popular especially for mid- to large-size applications. Hybrid control, for example having ...

4. 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. Hydropneumatic device - Wikipedia

   en.wikipedia.org/wiki/Hydropneumatic_device

   Hydropneumatic pump controllers provide a Means of control for multiple fixed delivery volume, low cost low complexity pumps; to provide variable flow as required by small (say +/- 10 psi) pressure increase or decrease of a system.

7. Air-mixing plenum - Wikipedia

   en.wikipedia.org/wiki/Air-mixing_plenum

   Most systems will use motorized dampers to control the air mixing, and controlled by the building management system (BMS), or controls system. Typically as the fresh air and exhaust air dampers are driven from 0% open to 100% open, the mixing damper will in turn be driven from 100% open to 0% open, so as to always ensure a constant volume of ...

8. HVAC control system - Wikipedia

   en.wikipedia.org/wiki/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. [1] 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 (e.g. start the ...

9. Building automation - Wikipedia

   en.wikipedia.org/wiki/Building_automation

   Analog outputs control the speed or position of a device, such as a variable frequency drive, an I-P (current to pneumatics) transducer, or a valve or damper actuator. An example is a hot water valve opening up 25% to maintain a setpoint. Another example is a variable frequency drive ramping up a motor slowly to avoid a hard start.
