Question

rooms are provided with ventilators and exhaust fans near the top sidewalls.

Answer 1

Rooms are provided with ventilators and exhaust fans near the top sidewalls because the air we breathe out is hot and stale which means that is is of low pressure, the winds blowing from the exhaust fans or the ventilators have fresh air, which is higher in pressure so it blows downwards. Since Winds always blow from the hotter to the colder, The hot stale air comes out making way for the fresh air. Hence, Rooms are provided with ventilators at the top sidewalls.
