Buildings.Experimental.DistrictHeatingCooling.SubStations.Validation
Package with models for validation
Information
This package contains models that validate the district heating and cooling substation models. The examples plot various outputs, which have been verified against analytical solutions. These model outputs are stored as reference data to allow continuous validation whenever models in the library change.
Extends from Modelica.Icons.ExamplesPackage (Icon for packages containing runnable examples).
