modelZonalFlow_ACS

Zonal flow with input air change per second

Extends from BuildingSystems.Airflow.Multizone.BaseClasses.ZonalFlow.

Information

This model computes the air exchange between volumes.

Input is the air change per seconds. The volume flow rate is computed as 

  V_flow = ACS * V

where ACS is an input and the volume V is a parameter.

Parameters

Revisions

  • August 18, 2014, by Michael Wetter:
    Removed parameter forceErrorControlOnFlow as it was not used. Changed message of assert statement to avoid an error in OpenModelica.
  • October 8, 2013 by Michael Wetter:
    Changed the parameter useConstantDensity to useDefaultProperties to use consistent names within this package. A conversion script can be used to update this parameter.
  • December 14, 2012 by Michael Wetter:
    Renamed protected parameters for consistency with the naming conventions.
  • July 20, 2010 by Michael Wetter:
    Migrated model to Modelica 3.1 and integrated it into the Buildings library.
  • January 4, 2006 by Michael Wetter:
    Implemented first version.
