The purpose of volume control dampers is to modulate airflow in HVAC systems. VCD dampers can be employed in low-to-medium pressure and velocity systems as an automated control damper. The blade design of the units increases free area and improves damper effectiveness.

A volume control damper is a mechanical device used in heating, ventilation, and air conditioning (HVAC) systems to regulate or control the flow of air within ducts. It’s typically installed within the ductwork and can be manually operated or motorized.

Here are some key points about volume control dampers:

  1. Function: They control the volume (amount) of air flowing through a duct by adjusting the size of the damper blades.

  2. Types:

    • Manual Dampers: Adjusted by hand or using a handle to change the blade position.
    • Motorized Dampers: Controlled electronically or through a building automation system (BAS), allowing for remote operation and automation.
  3. Location: Installed in HVAC ducts, usually where specific airflow adjustments are needed, such as in branch ducts or near diffusers.

  4. Construction: Typically made of galvanized steel or aluminum, with blades that can pivot to open or close, controlling airflow.

  5. Applications: Used in both residential and commercial HVAC systems to balance airflow, control zone temperatures, and improve energy efficiency by reducing unnecessary airflow to unused areas.

  6. Operation: Manual dampers are adjusted by hand, while motorized dampers can be controlled remotely via a control panel, thermostat, or building management system.

Volume control dampers play a crucial role in maintaining comfort and efficiency in HVAC systems by allowing precise control over airflow distribution throughout a building.
