.Buildings.Airflow.Multizone.BaseClasses.DoorDiscretized

Information

This is a partial model for the bi-directional air flow through a door.

To compute the bi-directional flow, the door is discretize along the height coordinate, and uses an orifice equation to compute the flow for each compartment.

The compartment area dA is a variable, which allows using the model for a door that can be open or closed.

Revisions

• January 8, 2019, by Michael Wetter:
  Moved parameter CD from Buildings.Airflow.Multizone.BaseClasses.DoorDiscretized to Buildings.Airflow.Multizone.DoorDiscretizedOpen.
  This is for #971.
• June 27, 2018, by Michael Wetter:
  Corrected old parameter annotation.
• June 6, 2018, by Michael Wetter:
  Removed term that assures non-zero flow rate in each path, and reformulated flow balance to ensure that model is symmetric. This is for #937.
• January 22, 2016, by Michael Wetter:
  Corrected type declaration of pressure difference. This is for #404.
• September 26, 2013 by Michael Wetter:
  Added missing each keyword.
• December 14, 2012 by Michael Wetter:
  Renamed protected parameters for consistency with the naming conventions.
• December 6, 2011 by Michael Wetter:
  Removed protected variable rhoAve.
• August 12, 2011 by Michael Wetter:
  Changed model to use the new function Buildings.Airflow.Multizone.BaseClasses.powerLawFixedM.
• July 20, 2010 by Michael Wetter:
  Migrated model to Modelica 3.1 and integrated it into the Buildings library.
• February 8, 2005 by Michael Wetter:
  Released first version.
