Michele,
There are two tools available for determining the
quantity of coupling airflow. One is Type97 (or Type98)
(both of which are links between TRNSYS and a freely
available software tool called CONTAM). The other is a
commercially available TRNSYS add-on called TRNFlow. The
idea behind both is that the Trnsys building thermal
model (Type56) provides zone temperatures to the airflow
model (CONTAM or TRNFlow). The airflow model takes those
temperatures (as well as ambient conditions and a
certain amount of building geometry with which the
thermal model is not usually concerned) and computes the
corresponding interzonal air flows. These are passed
back to Type56, which recomputes zonal temperatures.
Iteration continues until both the thermal and airflow
models agree.
kind regards,
David

Hi, I m designing
a church with different thermal zones and the
common surfaces are set to virtual surface. I
activated the coupling . What would be the ideal
coupling air flow?
