modelVentilationFlowRateSashOpening
Use different empirical expressions to determine the window ventilation flow rate by sash opening
Extends from Modelica.Icons.Example (Icon for runnable examples).
Information
This example checks the models that simulate the window ventilation flow rate with the sash opening. For the sash opening type, all models are set to the bottom-hung opening.
The result shows that the estimated volume flow can be quite different when using different models.
Warnings are triggered when boundary conditions for an empirical expression are out of range. This could lead to inaccurate calculation results.
This example is a stress test with a wide range of boundary conditions. These conditions can cause a lot of events and slow down the simulation. In practice, the warning will rarely be triggered.
