modelChimneyShaftWithVolume
Model that demonstrates the chimney effect with a dynamic model of a shaft
Extends from Modelica.Icons.Example (Icon for runnable examples).
Information
This model is identical to
Buildings.Airflow.Multizone.Examples.ChimneyShaftNoVolume,
except that the chimney model is not steady-state, but rather dynamic
as it contains an air volume. The air volume is approximated
as being well-mixed. (Stratified volumes could be approximated by
using multiple instances of the model sha that are
connected in series.)
