[TRNSYS-users] TRNSFlow air coupling

[Matthias Frechen]

Hello Adnan, 

 

If I understand you correctly you like to use TRNFLOW to analyze your building with the two airnodes, but your problem is that the virtual surface drawn in Trnsys3D will not be imported in TRNBuild. My suggestion is to draw a window between the two zones in Trnsys3D and edit the window in TRNbuild to a glazing with a g-value of 100% e.g. WINID10001. After that you could define your airlink between the two zones (A and B) in TRNFLOW e.g. with a large opening. With at least two more air links (from zone A to external node x and from zone B to external node y) your natural ventilation air network should work.

 

Kind regards

Matthias

Subject: [TRNSYS-users] TRNSFlow air coupling

 

Hello,
My project is to analyzed natural ventilation, for that i am using outside wind speed, direction, and pressure. I have two AIRNODES  A and B where wind comes from roof. i have a virtual surface between AIRNODES because this surface eliminated automatically when exported to TRNBuild, so i have to define coupling. For this reason, i coupled AIRNODES  A to B in the REGIME DATA of the AIRNODES. As a COUPLING from AIRNODES A to B Needs xxx kg/h air flow. where should i get these values this is actually my output. i think i have to use the air comes from outside, using the some output of TRNSFlow?? and then use this amount in REGIME data of AIRNODE coupling as an input xxx kg/h. 
can you please guide me that which output of TRNSFlow i should use?? or any other idea to doing the same??.
 
Thanks
