In general, Type56 doesn't really care what happens to the air that
leaves the zone. (note: this is NOT the case when Type56 is coupled
with COMIS or CONTAM). If you have an exhaust fan, you can simply
use an external model and use the zone air temperature and RH as the
inputs. What you do have to concern yourself with is where the
replacement air is going to come from. In otherwords, when the
exhaust fan turns on, it will depressurize the zone and some
replacement air will come into the zone. Type56 assumes that the
zone remains pressure neutral and does not do a mass balance. So it
is up to you to make sure that you add an equal amount of air into
the zone (using a VENTILATION type (as was correctly recommended by
Baboo Gowreesunker) or a coupling airflow to an adjacent zone).<br>

hi,<br>
<br>
Does anybody know how to blow out the hot air in type 56? i link
a fan trying to simulate flowing out of hot air, but there is no
mass flow rate in the output of type 56. <br>
<br>
Thank You<br>
