.BuildingSystems.Fluid.Interfaces.LumpedVolumeDeclarations

Information

This class contains parameters and medium properties that are used in the lumped volume model, and in models that extend the lumped volume model.

These parameters are used for example by BuildingSystems.Fluid.Interfaces.ConservationEquation, BuildingSystems.Fluid.MixingVolumes.MixingVolume and BuildingSystems.Fluid.HeatExchangers.Radiators.RadiatorEN442_2.

Revisions

• March 3, 2022, by Michael Wetter:
  Moved massDynamics to Advanced tab, added assertion for correct combination of energy and mass dynamics and changed type from record to block.
  This is for issue 1542.
• January 18, 2019, by Jianjun Hu:
  Limited the media choice. See #1050.
• November 9, 2018 by Michael Wetter:
  Limited choices of media that are displayed in the pull down menu of graphical editors.
  This is for issue 1050.
• April 11, 2016 by Michael Wetter:
  Corrected wrong hyperlink in documentation for issue 450.
• January 26, 2016, by Michael Wetter:
  Added quantity=Medium.substanceNames for X_start.
• October 21, 2014, by Filip Jorissen:
  Added parameter mFactor to increase the thermal capacity.
• August 2, 2011, by Michael Wetter:
  Set substanceDynamics and traceDynamics to final and equal to energyDynamics, as there is no need to make them different from energyDynamics.
• August 1, 2011, by Michael Wetter:
  Changed default value for energyDynamics to Modelica.Fluid.Types.Dynamics.DynamicFreeInitial because Modelica.Fluid.Types.Dynamics.SteadyStateInitial leads to high order DAE that Dymola cannot reduce.
• July 31, 2011, by Michael Wetter:
  Changed default value for energyDynamics to Modelica.Fluid.Types.Dynamics.SteadyStateInitial.
• April 13, 2009, by Michael Wetter:
  First implementation.
