modelHumidifier_u

Information

Model that tests the basic class that is used for the humidifier model. It adds and removes water for forward and reverse flow. The top and bottom models should give similar results, although the sign of the humidity difference over the components differ because of the reverse flow. The model computes differences of results that are expected to be close to each other after the initial transients decayed.

Revisions

• August 5, 2024, by Hongxiang Fu:
  Rewrote the protected model Humidifier to add two-port temperature sensors to replace sta_*.T and two-port mass fraction sensors to replace sta_?.X[1]. This is for IBPSA #1913.
• November 2, 2016, by Michael Wetter:
  Changed assertions to blocks that compute the difference, and added the difference to the regression results.
  This is for issue 564.
• May 30, 2014, by Michael Wetter:
  Changed initialization of mass dynamics to avoid overspecified system of equations if the medium model is incompressible.
• October 9, 2013, by Michael Wetter:
  Introduced protected model Humidifier so that states at the fluid ports can be computed without having to use a conditionally removed variable. This is required for the model to pass the model check in Dymola 2014 FD01 beta3 with Advanced.PedanticModelica=true;.
• January 24, 2013, by Michael Wetter:
  Set initial conditions to Modelica.Fluid.Types.Dynamics.FixedInitial.
• July 11, 2011, by Michael Wetter:
  Moved model to Buildings.Fluid.Interfaces.Examples.
• April 18, 2008, by Michael Wetter:
  First implementation.
