What is stratification? Is it more likely to occur at places with low ceilings or places with high ceilings? How does it cause thermal discomfort for a room’s occupants? How can stratification be prevented?
What will be an ideal response?
Stratification is the formation of vertical still air layers in a room at difference temperatures, with highest temperatures occurring near the ceiling. It is likely to occur at places with high ceilings. It causes discomfort by exposing the head and the feet to different temperatures. This effect can be prevented or minimized by using destratification fans (ceiling fans running in reverse).
