What type of HVAC system is characterized by poor air distribution and ventilation and low system heat loads?
Official USCG Answer & Rule Citation
Correct Answer: Option A — A variable air volume system
Variable air volume (VAV) systems adjust airflow to meet changing thermal loads. However, at low load conditions, the reduced air velocity can lead to poor air distribution and inadequate ventilation within the space, as the system prioritizes energy savings over maintaining constant air circulation patterns throughout the served area.
