Referring to illustrated diagram, what type of HVAC system is shown? Illustration GS-RA-43
AI Explanation
The correct answer is C) A dual duct system.
A dual duct system is an HVAC system that uses two separate ductwork systems - one for hot air and one for cold air. This allows the system to deliver a customized mix of hot and cold air to different zones, providing individualized temperature control. This matches the description of the HVAC system shown in the illustrated diagram GS-RA-43.
The other answer choices do not accurately describe the system depicted. A single zone system only has one temperature zone, a variable air volume system uses a single duct with dampers to vary airflow, and a terminal reheat system uses a single duct with reheating coils near the outlets.
