Variable Air Volume Systems

VAV Box Systems

Here is a brief overview of how variable air volume boxes work and why it makes sense to contact us for your VAV system needs.

VAV Box Systems Design

Variable air volume boxes have several key components that work together to deliver the proper amount of treated air to one or more thermostatically controlled zones. The components include:

• A central air handling unit to force treated air through ducts to the space to be heated or cooled.
• A VAV zone terminal (VAV box) connected to the duct work that is fitted with a damper that can be opened or closed incrementally to increase or reduce the flow of treated air.
• Air flow and air pressure sensors to optimize damper control.
• A thermostat connected to the damper controller to regulate its position so that the proper amount of treated air is forced into the space.
• A heating element (optional) that moves heated air to the space served.
