modelTraceSubstances
Test model for the extra property sensor
Extends from Modelica.Icons.Example (Icon for runnable examples).
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.

Replaced fluid source. This is for #1072. -

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. -

Changed initialization of volume to fixed initial values to avoid a translation warning in OpenModelica. -

Renamed example and added an instance of BuildingSystems.Fluid.Sensors.TraceSubstancesTwoPort. -
