Why it is good to place ventilators at the top of the walls?

1.	Why it is good to place ventilators at the top of the walls?
Answer» Answer: My answer is Explanation: VENTILATORS are provided in the rooms at the top of the roofs because if the air inside the ROOM GETS hot, the hot air rises up and FLOWS through these ventilators and THUS cool air remains at bottom. It brings cool and fresh air in the room. Thus ventilators maintain conventional currents to keep the air fresh in the room.
