Model with three rooms for the validation of the multizone air exchange models

Extends from Modelica.Icons.Example (Icon for runnable examples).

Information

This is a model of three rooms that exchange air among each based on density difference between the air in the rooms and the outside. The model implements the configuration shown below.

Configuration of the three rooms.

This model has been used for a comparative model validation between CONTAM and the Buildings library. See Wetter (2006) for details of the validation.

Revisions

  • December 22, 2014 by Michael Wetter:
    Removed Modelica.Fluid.System to address issue #311.
  • June 26, 2014, by Michael Wetter:
    Set the initial conditions to be fixed to avoid a translation warning. This required adding a heat conductor between each volume and its prescribed temperature in order to avoid an overdetermined system of equations.
  • November 10, 2011, by Michael Wetter:
    Added documentation.
