Information

This example compares the steam humidifier component to the steam humidifier models in the Fluid-package.


The results show good agreement with small differences that can be explained the following way.


The enthalpy of condensing gas in the medium model of the Fluid-package use the enthalpy of vaporization at 0 °C and the temperature difference to 0 °C multiplied with the specific heat capacity of steam.

The components in this package calculate the enthalpy difference of liquid water from 100 °C to the parameter TWatIn. Then the evaporation is calculated with the enthalpy of vaporization at 100 °C. Additional increase in temperature is possible using the specific heat capacity of steam.
