DCV for multizone VAV

Abstract

Most designers provide dilution ventilation by introducing outdoor air at a rate determined by zone population, zone area, occupancy category, and ventilation-system type to promote acceptable indoor air quality (IAQ). Demand-controlled ventilation (DCV) is a ventilation system capability that provides for the automatic reduction of outdoor air intake below design rates when the actual occupancy of spaces served by the system is less than design Occupancy. It offers a means to ensure adequate outdoor airflow (OA) for acceptable IAQ while reducing energy consumption at part-load conditions. Most HVAC design engineers consider using DCV for densely occupied zones and zones with large occupancy fluctuation. DCV is also allowed by Standard 62.1 and is required by Standards 90.1 and 189.1.
