What type of HVAC system is characterized by having control dampers in locations other than the outside air supply, outside air exhaust, and recirculation damper applications?
AI Explanation
The correct answer is D) A variable air volume system.
In a variable air volume (VAV) system, control dampers are located not only in the outside air supply, outside air exhaust, and recirculation air paths, but also within the ductwork system to regulate the airflow to individual zones or terminal units. This allows the system to adjust the airflow to each zone based on the heating or cooling demand, improving energy efficiency compared to constant volume systems.
The other options are incorrect because they do not typically have dampers in locations other than the outside air, exhaust, and recirculation paths. A terminal reheat system (A) has no additional dampers, a single zone system (B) has no need for zone-level dampers, and a dual duct system (C) has separate hot and cold air ducts but no additional dampers.
