Three way valve with linear characteristics

Extends from BaseClasses.PartialThreeWayValve.

Information

Three way valve with linear opening characteristic.

This model is based on the partial valve models BuildingSystems.Fluid.Actuators.BaseClasses.PartialThreeWayValve and BuildingSystems.Fluid.Actuators.BaseClasses.PartialTwoWayValve. See BuildingSystems.Fluid.Actuators.BaseClasses.PartialThreeWayValve for the implementation of the three way valve and see BuildingSystems.Fluid.Actuators.BaseClasses.PartialTwoWayValve for the implementation of the regularization near the origin.

Revisions

  • March 7, 2022, by Michael Wetter:
    Set final massDynamics=energyDynamics.
    This is for #1542.
  • June 10, 2021, by Michael Wetter:
    Changed implementation of the filter and changed the parameter order to a constant as most users need not change this value.
    This is for #1498.
  • November 5, 2019, by Michael Wetter:
    Moved assignment of leakage from BuildingSystems.Fluid.Actuators.BaseClasses.PartialThreeWayValve to the parent classes.
    This is for #1227.
  • February 20, 2012 by Michael Wetter:
    Renamed parameter dp_nominal to dpValve_nominal, and added new parameter dpFixed_nominal. See BuildingSystems.Fluid.Actuators.UsersGuide.
  • February 14, 2012 by Michael Wetter:
    Added filter to approximate the travel time of the actuator.
  • March 25, 2011, by Michael Wetter:
    Added homotopy method.
  • June 16, 2008 by Michael Wetter:
    First implementation.
