For accurate ventilation, air handling units should be positioned in which location?

Positioning air handling units above corridors and toilets is optimal for several reasons related to ventilation efficiency and system functionality. It allows for effective distribution of conditioned air throughout the building while being strategically placed to deliver fresh air to common areas where air circulation is essential. This location can also facilitate easier access for maintenance and repairs, which is important for ensuring consistent operation and longevity of the equipment.

The design also benefits airflow patterns; by placing the air handling units in these areas, the system can utilize the vertical space for better air movement and reduce the length of ductwork required, enhancing system efficiency. Additionally, placing units above corridors helps to minimize noise in occupied spaces, ensuring that classrooms and other areas remain conducive to learning and work.
