Where should exhaust fans be located in a ventilation system?

Exhaust fans should be located at the discharge end of the ventilation system to effectively remove stale or contaminated air from the occupied space. Positioning the fans at this end ensures that the air is expelled from the building or environment, thereby creating a negative pressure that allows fresh air to enter through the intake points. This strategic placement helps maintain adequate airflow and ensures that the ventilation system functions efficiently, effectively displacing the indoor air while pulling in fresh outdoor air.

Placing exhaust fans randomly throughout the system would not create the necessary airflow dynamics needed for effective ventilation. An intake location would not facilitate the effective expulsion of air, and suggesting that exhaust fans are unnecessary overlooks the critical role they play in managing air quality and maintaining a healthy indoor environment. Therefore, having them at the discharge end is crucial for the overall effectiveness and efficiency of the system.
