Refrigeration & Air Conditioning USCG Question #584 (Set 12)

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 C — A variable air volume system

Variable air volume (VAV) systems modulate supply air quantities to match thermal loads. In spaces with very low heat loads, minimum damper positions can restrict airflow, resulting in sluggish air distribution, poor ventilation, and stagnant pocket formation.
