.IDEAS.Fluid.Sources.OutsideAir

Information

This model describes boundary conditions for pressure, enthalpy, and CO2 that can be obtained from weather data. These data are obtained from the SimInfoManager, which should be included in the model.

Note that boundary temperature, mass fractions and trace substances have only an effect if the mass flow is from the boundary into the port. If mass is flowing from the port into the boundary, the boundary definitions, with exception of boundary pressure, do not have an effect.

Revisions

• August 18, 2025, by Klaas De Jonge:
  refactored embedded windPressureProfile function to receive support points and derivatives as fixed parameters to avoid overhead each time the funtion is called (which is often for pressure driven airflow models). Changed OutsideAir model accordingly.
• July 9, 2025, by Jelger Jansen:
  Update documentation of A0 and a. See #1340.
• October 30, 2024, by Klaas De Jonge:
  Modifications for wind pressure,ambient pressure and wind speed modifiers used in interzonal airflow.
• November 13, 2023 by Filip Jorissen:
  Computing stack height.
• July 21, 2022 by Filip Jorissen:
  Added optional dry bulb temperature input for #1270.
• September 21, 2019 by Filip Jorissen:
  First implementation.
