  • VAV systems are designed to adjust the volume of air supplied to different areas of a building based on the demand. VAV boxes are typically used in commercial or large residential buildings to maintain consistent comfort by optimizing energy efficiency. They control airflow in response to temperature changes and occupancy, ensuring that areas do not receive too much or too little air.

  • Dampers are devices used in HVAC systems to regulate the flow of air through ducts. They can be manual or automated, with automated dampers commonly integrated into the VAV system to adjust airflow precisely. By closing or opening partially or fully, dampers control the direction and amount of airflow, preventing system overloading and ensuring consistent climate control.
