What is the correct air discharge point for floor-mounted air handling units?

The correct air discharge point for floor-mounted air handling units being at waist level or higher ensures that the conditioned air is effectively distributed throughout the space. Positioning the discharge at this height allows for better circulation and mixing of the air within the room, promoting even temperature distribution and enhancing overall comfort. Additionally, discharging air at waist level or above can help prevent air from lingering at the floor level where it may not be as effective in reaching upper areas of the room, thus improving the efficiency of the air handling unit.

Choosing a discharge point that is too low, such as under 10 feet at floor level, risks not facilitating adequate air mixing. Similarly, discharging air at floor level over 10 feet away from the unit would not effectively channel the airflow where it's needed, leading to cold or hot spots and reduced efficiency. An overboard discharge is not applicable for air handling units intended for maintaining indoor climate control, as it would direct the air outside rather than utilizing it indoors. Therefore, positioning the discharge point at waist level or higher aligns with best practices in HVAC design for comfort and efficiency.
