modelX3WithRadiantFloor
Example model of test cells X3A and X3B connected to form test bed X3
Extends from Modelica.Icons.Example (Icon for runnable examples).
Information
This example models demonstrates how the Buildings.ThermalZones.Detailed.FLEXLAB.Rooms.X3A and Buildings.ThermalZones.Detailed.FLEXLAB.Rooms.X3B test cell models can be combined to form a simulation of test bed X3. The example is primarily a combination of Buildings.ThermalZones.Detailed.FLEXLAB.Rooms.Examples.X3AWithRadiantFloor and Buildings.ThermalZones.Detailed.FLEXLAB.Rooms.Examples.X3BWithRadiantFloor. The example Buildings.ThermalZones.Detailed.FLEXLAB.Rooms.Examples.X3AWithRadiantFloor contains detailed documentation on these models. Some small changes were necessary to create the model of the test bed correctly. These changes are:
- To make the connection between X3A and X3B possible two of the models from the X3A example were replaced with models designed for connection to X3B.
- Connections between the two test cells do not exist in either of the other two examples.
- The data reader models in this example function in the same manner as in the
other two examples, but their names had to be changed to avoid using the same name
for multiple models in this example. Their names now contain a suffix describing the test
cell they're connected to. For example,
airConAis connected to test cell X3A andshaPosBis connected to test cell X3B. - TNei now only contains a temperature for test cell X2B. A temperature input for X3B is not needed because that test cell is now included in the model.
