Minimum Outside Air Damper Control
Journal Article by ASHRAE, 2002
Larry Felker
More info
Full Description
This article addresses maintaining constant minimum outside air in variable air volume (VAV) systems as supply air quantity changes. Figure 1 shows a typical outside air (OA) intake system and lists some factors that affect flow through the OA intake. The outside air minimum ventilation control must be coordinated with those other factors. A discussion of how to achieve that coordination is reserved for another article. This article focuses on the minimum outside air control.
