.Buildings.Fluid.Sensors.Examples.TraceSubstances

Information

This example tests the sensors that measure trace substances. A CO₂ mass flow rate of 8.18E-8 kg/kg is added to the volume. The volume also has a fresh air mass flow rate and an exhaust air mass flow rate. The initial CO₂ concentration of the volume is 0 kg/kg. Note that the fresh air supply has zero carbon dioxide concentration. Therefore, if it were outside air, then all concentrations are relative to the outside air concentration.

Revisions

• May 2, 2019, by Jianjun Hu:
  Replaced fluid source. This is for #1072.
• May 22, 2015, by Michael Wetter:
  Updated example to test the correction for issue 249.
• May 8, 2014, by Michael Wetter:
  Added a pressure drop element, as otherwise the initialization problem is overspecified for incompressible media.
• November 27, 2013 by Michael Wetter:
  Changed sink model from a prescribed flow source to a pressure boundary condition. This is required for the new air model, which is incompressible. Otherwise, there will be no pressure reference in the system.
• September 10, 2013 by Michael Wetter:
  Changed initialization of volume to fixed initial values to avoid a translation warning in OpenModelica.
• August 30, 2013 by Michael Wetter:
  Renamed example and added an instance of Buildings.Fluid.Sensors.TraceSubstancesTwoPort.
• September 29, 2009 by Michael Wetter:
  First implementation.
