Detailed mathematical models of VAV equipment and subsystems have been developed and used tocompose larger DCV systems with a large degree of detail. The models and systems take intoaccount both flow/pressure distribution and thermal/contaminant dynamics. The models have beenvalidated against measurements. A number of detailed simulation cases have been conducted. Theresults show that energy usage depends strongly depends on occupancy, flow rates, chosen setpoints as well as the outdoor temperature.
