Model with three closed doors
Extends from Modelica.Icons.Example (Icon for runnable examples).
Information
This model consists of three volumes that are connected among
each other through three doors that all have the same geometry.
All doors are closed, but they are not air-tight.
Heat is added and removed from volB which induces
a small air flow through the doors.
This model uses Buildings.Media.Specialized.Air.PerfectGas as the medium because Buildings.Media.Air does not account for expansion if air the air is heated.
