Information

Model that demonstrates the use of an ideal humidifier. Both humidifer models are identical, except that one model is configured as a steady-state model, whereas the other is configured as a dynamic model. Both humidifiers add water to the medium to track a set-point for the outlet temperature using adiabatic cooling. The temperature of the water that is added to the medium is determined by the parameter T of the humidifier models.

  • April 23, 2013, by Michael Wetter:
    Added flow resistance at the outlet of the humidifier to avoid a numerical derivative, and changed model to use a prescribed mass flow rate.

    First implementation.
