Partial example model for a rear door heat exchanger
Extends from Modelica.Icons.Example (Icon for runnable examples).
Information
Partial example model for a rear door heat exchanger.
This model declares the medium packages, nominal parameters,
fluid boundary conditions, temperature sensors, and their connections.
Extending models must declare the heat exchanger instance hex,
provide the value of mAir_flow_nominal,
and add the four connections involving hex.
