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.<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US style='font-size:10.0pt;font-family:"Verdana",sans-serif;mso-fareast-language:EN-US'><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-US style='font-size:10.0pt;font-family:"Verdana",sans-serif;mso-fareast-language:EN-US'>Kind regards<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US style='font-size:10.0pt;font-family:"Verdana",sans-serif;mso-fareast-language:EN-US'>Matthias<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US style='font-size:10.0pt;font-family:"Verdana",sans-serif;mso-fareast-language:EN-US'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:8.0pt;font-family:"Verdana",sans-serif;color:#7F7F7F'>Dipl.-Ing Matthias Frechen<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:8.0pt;font-family:"Verdana",sans-serif;color:#7F7F7F'>jh-planungsgesellschaft mbH<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:8.0pt;font-family:"Verdana",sans-serif;color:#7F7F7F'>Lindenstr. 63 | 14467 Potsdam | t: 033203 87498 | e: <a href="mailto:frechen@jh-plan.de"><span style='color:#0563C1'>frechen@jh-plan.de</span></a><o:p></o:p></span></p><p class=MsoNormal><span style='font-size:10.0pt;font-family:"Verdana",sans-serif;mso-fareast-language:EN-US'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:10.0pt;font-family:"Verdana",sans-serif;mso-fareast-language:EN-US'><o:p> </o:p></span></p><div style='border:none;border-top:solid #E1E1E1 1.0pt;padding:3.0pt 0cm 0cm 0cm'><p class=MsoNormal><b><span lang=EN-US>From:</span></b><span lang=EN-US> TRNSYS-users <<a href="mailto:trnsys-users-bounces@lists.onebuilding.org">trnsys-users-bounces@lists.onebuilding.org</a>> <b>On Behalf Of </b>adnan rasheed via TRNSYS-users<br><b>Sent:</b> Mittwoch, 27.

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. <o:p></o:p></span></pre><pre style='white-space:pre-wrap'><span lang=EN-US style='color:black'>can</span><span lang=EN-US style='font-family:"Arial",sans-serif;color:black'> you please guide me </span><span lang=EN-US style='color:black'>that</span><span lang=EN-US style='font-family:"Arial",sans-serif;color:black'> which output of TRNSFlow </span><span lang=EN-US style='color:black'>i should</span><span lang=EN-US style='font-family:"Arial",sans-serif;color:black'> use?? or any other idea to </span><span lang=EN-US style='color:black'>doing</span><span lang=EN-US style='font-family:"Arial",sans-serif;color:black'> </span><span lang=EN-US style='color:black'>the same??.<o:p></o:p></span></pre><pre style='white-space:pre-wrap'><span lang=EN-US style='color:black'><o:p> </o:p></span></pre><pre style='white-space:pre-wrap'><span lang=EN-US style='color:black'>Thanks<o:p></o:p></span></pre></div><p class=MsoNormal><span lang=EN-US>-- <o:p></o:p></span></p><div><div><div><div><div><div><p class=MsoNormal><span lang=EN-US style='font-family:"Georgia",serif;color:#666666'>Adnan Rasheed</span><span lang=EN-US><o:p></o:p></span></p><div><p class=MsoNormal><span lang=EN-US style='font-family:"Georgia",serif;color:#666666'>Post-doc Research Fellow</span><span lang=EN-US><o:p></o:p></span></p></div><div><p class=MsoNormal><span lang=EN-US style='font-family:"Georgia",serif;color:#666666'>Kyungpook National University</span><span lang=EN-US><o:p></o:p></span></p></div><div><p class=MsoNormal><span lang=EN-US style='font-family:"Georgia",serif;color:#666666'>Daegu, South Korea.</span><span lang=EN-US><o:p></o:p></span></p></div><div><p class=MsoNormal><span lang=EN-US style='font-family:"Georgia",serif;color:#666666'>+82-102762-0105</span><span lang=EN-US><o:p></o:p></span></p></div><div><p class=MsoNormal><a href="mailto:adnan.upm.spain@gmail.com" target="_blank"><span lang=EN-US style='font-family:"Georgia",serif'>adnan.upm.spain@gmail.com</span></a><span lang=EN-US style='font-family:"Georgia",serif;color:#666666'>, </span><a href="mailto:adnanrasheed@knu.ac.kr" target="_blank"><span lang=EN-US style='font-family:"Georgia",serif'>adnanrasheed@knu.ac.kr</span></a><span lang=EN-US><o:p></o:p></span></p></div></div></div></div></div></div></div><p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p><div id=mt-signature><table class=MsoNormalTable border=0 cellspacing=0 cellpadding=0><tr><td style='padding:4.8pt 4.8pt 4.8pt 4.8pt'><p class=MsoNormal><a href="https://mailtrack.io/?utm_source=gmail&utm_medium=signature&utm_campaign=signaturevirality5&"><span style='mso-fareast-language:EN-US;text-decoration:none'><img border=0 width=32 height=32 style='width:.3333in;height:.3333in' id="_x0000_i1026" src="https://s3.amazonaws.com/mailtrack-signature/sender_notified.gif" alt=Mailtrack></span></a><span style='mso-fareast-language:EN-US'><o:p></o:p></span></p></td><td style='padding:4.8pt 4.8pt 4.8pt 4.8pt'><p class=MsoNormal><span lang=EN-US style='color:#777777;mso-fareast-language:EN-US'>Sender notified by</span><span lang=EN-US style='mso-fareast-language:EN-US'> <br></span><span style='mso-fareast-language:EN-US'><a href="https://mailtrack.io?utm_source=gmail&utm_medium=signature&utm_campaign=signaturevirality5&"><span lang=EN-US style='color:#4374F7'>Mailtrack</span></a></span><span style='mso-fareast-language:EN-US'> </span><span lang=EN-US style='font-size:1.0pt;mso-fareast-language:EN-US'>05/27/20, 04:21:46 PM</span><span lang=EN-US style='mso-fareast-language:EN-US'> <o:p></o:p></span></p></td><td style='padding:4.8pt 4.8pt 4.8pt 4.8pt'></td></tr></table></div><p class=MsoNormal><img border=0 width=1 height=1 style='width:.0083in;height:.0083in' id="_x0000_i1025" src="https://mailtrack.io/trace/mail/c16a55d1f06e269c566c7449a9f8f1d1d5805947.png?u=2838774"><o:p></o:p></p></div></div></body></html>
