Course description: AEC Daily: An Introduction to Air Control Dampers
Air control dampers are an essential component of a building’s HVAC system, regulating heating, cooling, and ventilation performance. Presented here is an introduction to control, balancing, backdraft, industrial, and multizone dampers; each type plays an important role in the HVAC system. Discussed are damper types, components, and performance metrics. Guidance is provided for damper specification, installation, and maintenance and inspection.
Identify the different types of air control dampers and how they maintain acceptable indoor air quality and occupant comfort by regulating heating, cooling, and ventilation performance.
Recall the function of individual damper components and accessories and identify how they contribute to meeting HVAC system performance requirements.
Discuss the performance metrics of dampers, such as free area, pressure drop, airflow direction, and air leakage, and their relationship with a correctly sized and balanced HVAC system.
Select and size an air control damper for various duct types, sizes, and applications.
