Using DV Systems for High Heat Gain Applications
Displacement ventilation (DV) systems are revolutionizing how large spaces are cooled and ventilated. Although mostly known for their ability to provide exceptional indoor air quality, DV systems can also reduce total airflow requirements in certain applications.

Promoting Healthy Indoor Air Quality in the Classroom
As HVAC professionals, one of our primary goals is to promote healthy indoor air quality in all spaces, and there are fewer applications where this is more important than in classrooms. It is estimated that approximately half of public school districts need to update or replace the HVAC systems in their schools.1

Exploring the Benefits of Displacement Ventilation in Schools
For years, studies have linked healthy environments in schools with improved educational outcomes for students. We’ve seen that indoor air quality has a major impact on health, performance and attendance and that quiet classrooms improve academic performance, reduce stress and encourage better behavior.

A CFD Classroom Case Study
Obtaining efficient ventilation with overhead mixing systems for applications in heating climates can be a challenge. Not only does the positive buoyancy of the supply air work against the air distribution system, but most overhead mixing systems are designed with low supply air volumes (relative to cooling) and high supply air temperatures (more than 15°F above room temperature).
