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?

Correct Answer: Option D — A variable air volume system

Variable air volume (VAV) systems employ terminal control dampers to regulate the quantity of air delivered to a space based on thermal load. Unlike constant volume systems, these dampers modulate airflow while maintaining a constant supply temperature, optimizing energy efficiency and comfort across varying shipboard environmental conditions.
