MODELING AND VALIDATION OF EXISTING VAV SYSTEM COMPONENTS

Nabil Nassif, Stanislaw Kajl, Robert Sabourin

Abstract: Variable air volume (VAV) component models are required for different applications to improve the energy efficiency. Fan, damper as well as valve and cooling coil models are developed and presented in this paper. All model parameters are taken from the respective manufacturers or derived from the monitored data of an existing VAV system. Adaptive models are also presented, thus placing their parameters on-line and keeping them updated. The developed component models are validated against the monitoring data from the investigated existing VAV system. 2. Supply air and water temperatures (T sa and T sw , respectively) 3.
