This model contains a completely mixed fluid volume and models that take into account the pressure difference of a medium column that is at the same temperature as the fluid volume. It can be used to model the pressure difference caused by a stack effect.
Set the parameter use_HeatTransfer=true
to expose
a heatPort
. This heatPort
can be used
to add or subtract heat from the volume. This allows, for example,
to use this model in conjunction with a model for heat transfer through
walls to model a solar chimney that stores heat.
For a steady-state model, use Buildings.Airflow.Multizone.MediumColumn instead of this model.
In this model, the parameter h
must always be positive, and the port port_a
must be
at the top of the column.
