VAV is an acronym that stands for Variable Air Volume. It refers to a type of HVAC (Heating, Ventilation, and Air Conditioning) system commonly used in commercial and industrial buildings. This system is designed to provide varying amounts of conditioned air to different regions or zones within a building based on the specific needs and demands of each zone.
The VAV system consists of several key components, including a central air handling unit, a series of supply air ducts, variable air volume boxes, and multiple thermostats or temperature sensors strategically located throughout the building. These components work together to regulate the flow of conditioned air and maintain comfortable indoor temperatures in each zone.
One of the main advantages of a VAV system is its ability to save energy by supplying only the necessary amount of conditioned air to each zone. By utilizing variable air volume boxes, the system can adjust the airflow to match the heating or cooling requirements of the particular area. This allows for better temperature control and minimizes energy waste compared to constant air volume systems.
Additionally, VAV systems often incorporate dampers or valves in the air ducts, which can be adjusted to further control the airflow. This feature allows for better zoning within a building, enabling different temperatures to be maintained in different spaces according to their specific needs.
In conclusion, VAV refers to a Variable Air Volume system used in HVAC systems to regulate the flow of conditioned air to different zones within a building, optimizing energy efficiency and providing customized temperature control.
