What Is VAV (Variable Air Volume)?

August 19, 2023 | My HVAC Price

Variable Air Volume (VAV) is an HVAC system design and control strategy that adjusts the volume of conditioned air delivered to different zones or spaces within a building based on their specific heating or cooling requirements. In a VAV system, the airflow rate is modulated to match the changing demands of the zones, allowing for more precise temperature control and energy efficiency.

VAV systems typically consist of a central air handling unit that supplies a varying amount of air to individual zones through a network of ductwork. Each zone is equipped with a VAV box or damper that regulates the airflow and temperature according to the needs of that area.

What are the benefits of using VAV systems?

VAV systems offer benefits such as improved energy efficiency, precise temperature control in individual zones, reduced energy consumption during low-demand periods, and the ability to customize comfort settings for different spaces within a building.

Where are VAV systems commonly used?

VAV systems are commonly used in commercial buildings, offices, and other spaces with varying occupancy and thermal loads. They are particularly effective in larger buildings with multiple areas that require individualized temperature control.

Can VAV systems be integrated with building automation systems?

Yes, VAV systems can be integrated with building automation systems (BAS) to enhance control, monitoring, and optimization. BAS allows for centralized management of HVAC operations, scheduling, and energy-saving strategies, further improving the efficiency and performance of VAV systems.
