Question

why are exhaust fans fitted near the ceiling​

Answer 1

hey mate exhaust fans are fitted near the ceiling because the hot air is lighter so it will float over cold air due to which exhaust fans help the hot air to pass on

Answer 2

Answer:

Fans are fitted near the ceiling or on the sides of the walls due to the convection current as the warm and light air rises up and escapes through the fan and fresh air comes inside the room through windows as the air is cooler and heavier with respect to the air that was ventilated out of the room.
