modelX3BWithRadiantFloor
Example model showing a use of X3B
Extends from Modelica.Icons.Example (Icon for runnable examples).
Information
This model demonstrates one potential simulation using the models available in Buildings.ThermalZones.Detailed.FLEXLAB.Rooms.X3B. This model is nearly identical to Buildings.ThermalZones.Detailed.FLEXLAB.Rooms.Examples.X3AWithRadiantFloor. For a description of most of the connections and reasons behind them see that documentation. The changes to make this example model are:
- The room models were changed from X3A models to X3B models.
- Buildings.ThermalZones.Detailed.FLEXLAB.Rooms.X3B.TestCell has one external wall (modeled in datConExt) which was a dividing wall (modeled in datConBou) in Buildings.ThermalZones.Detailed.FLEXLAB.Rooms.X3A.TestCell. Because of this, a few construction indexes changed. Connections were made according to the table in Buildings.ThermalZones.Detailed.FLEXLAB.Rooms.X3B.
