Referring to the illustrated diagram, what type of HVAC system is shown? Illustration GS-RA-43
AI Explanation
The correct answer is A) A dual duct system.
A dual duct system, as shown in the illustrated diagram GS-RA-43, is a type of HVAC system that consists of two separate air ducts - one carrying warm air and the other carrying cool air. These two air streams are then mixed at the terminal units to provide the desired temperature and airflow to the conditioned space. This system allows for greater control and flexibility in temperature regulation compared to other HVAC configurations.
The other options are incorrect because: B) A variable air volume system typically has a single duct with dampers to adjust airflow, C) A single zone system has a single air supply for the entire space, and D) A terminal reheat system uses a single duct with a reheating coil at each terminal unit.
