Displacement Ventilation

For decades, hundreds of schools throughout the US have been applying displacement induction ventilation with the QLCI diffuser.  Join us to learn how and why this technology checks so many of the boxes critical to classroom ventilation design for proven year-round better IAQ.

This presentation will clarify design concepts between the predominant ventilation types compared to operational characteristics of displacement induction ventilation.  By applying displacement induction ventilation in occupied spaces such as classrooms, designers, architects and owners will recognize the following:

1. Improved IAQ through increased ventilation effectiveness (contaminant removal effectiveness) as defined in ASHRAE 62.1
2. Improved thermal comfort for students and staff
3. Improved acoustics due to no additional air moving devices in the zone
4. Decreased maintenance due to no moving parts in the zone
5. Increased system efficiencies and utility savings versus comparable systems
