TRNBuild (Type56) only asks the user to provide the amount of air
flow from zone "A" into zone "B" (note that Type56 does NOT assume that
an equal amount of air flows back from zone "B" to zone "A" so you have
to take care of the mass balance manually). TRNFlow actually figures
out what the flows back and forth would be based on temperature
differences, pressure differences, and mechanical systems in the two
zones. It also takes into account the entire building, not just the two
zones. I imagine that it would be very hard to run exactly the same
case using TRNBuild and setting the mass flows manually and using
TRNFlow. Even if the flow between the two zones is the same, it may be
that TRNFlow is calculating some other flows elsewhere (increased
infiltration for example).<br>
Kind regards,<br>

style="" lang="EN-GB">Dear TRNsys-users<br>
<br>
I simulate the same flow between two zones with TRNbuild and TRNflow.<br>
But I don't have same results.<br>
It seems to me that the evolution of temperature is more realistic than
temperature with coupling airflow of TNRbuild.<br>
<br>
I want to know if I can continue to simulate coupling airflow with
TRNbuild or not? <br>
<br>
Best Regards.</span></p>
