This example illustrates the use of the models that
exchange a prescribed flow rate between the
volumes that are attached to it.
ACS prescribes the air exchange rate to
5 air changes per hour.
zonFlo takes as an input the air change per seconds,
and the instance
floExc takes as inputs the mass flow rate.
For both instances, the air flows from
