[TRNSYS-users] TRNFLOW and thermal relation between two airnodes

[Wirich Freppel]

Hi all,

I designed with google sketchup 2 boxes, 1m3 each. Those two boxes are
adjacent to each other.
I set up the adjacent surface between both as a virtual surface, expecting
that the two airnodes would be linked to each other (air motion link).
I assumed that if I set up a ventilation rate in one airnode, the other
airnode would be affected, and the two air temperatures would be really
close to each other. Because I assumed that thanks to the virtual surface,
the two airnodes would act like one airnode.
However there is not such link between both according to the air
temperature result.

Therefore, I coupled the two airnodes in the TYP56, but i'm surprised that
I have to set up a ventilation rate between the airnodes.
Also, I dont understand why there are "upper" and "lower" configurations.

Finally, I tried to couple the two airnodes using TRNFLOW, but when I use
"large opening", nothing appear on the left frame, which still shows
"undefined". Thus I get an error when I try to close TRNBUILD.

I think I don't use TRNFLOW or the coupling option correctly. Can someone
help me or direct me to a tutorial so that I can learn how to couple the
two airnodes properly?

Thanks a lot in advance

Regards
