modelDemandControlledAHU
Example for air handling unit with demand controlled ventilation
Extends from Modelica.Icons.Example.
Information
This example shows the combination of theGenericAHU with a ThermalZone.
The used controller is designed for demand controlled ventilation (DCV) based on the CO2-Concentration in the zone.
The Example provides a ready-to-use framework for testing and tuning controllers.
The nominal values for heat exchangers are derived from data sheets and experimental data of a test bench air handling unit at the Institute for Energy Efficient Buildings and Indoor Climate.
Parameters

|---|---|---|---|
| Real | CO2Con_start | 400 | Start value for CO2 concentration in the thermal zone in ppm |
| Real | CO2ConAmb | 450 | CO2 concentration in ambient air in ppm |
