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



Dear TRNFlow-User,

 

attached you can find a TRNFlow-Tutorial. You can also find in in your TRNSYS directory under …\Studio\Lib\Comis\Documentation\.

If this is not helpful, please send your TRNSYS-project to hotline@trnsys.de and we will have a look at it.

 

Best regards

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

 

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
