Extends from Modelica.Icons.Example (Icon for runnable examples).
Information
In a third step, an additional cooling air stream is introduced, commonly referred to as ram air in aircraft applications.
Additionally sensors are added that provide the specific enthalpy at the inlet and outlet.
Further documentation is available in the AirCycle package.
