Dear all, <br><br><br>I want to compare the test room infiltration rate of actual measurement with by
TRNSYS simulation. Maybe as you know, in the TRNFlow manual: there it is
explained that "As soon as TRNFLOW is
turned on, (...) in the simulation the defined infiltrations,
ventilations and couplings will be replaced with the calculated air
flows."<br>
I defined CO2% as 1000 ppm in TRNFlow, then I want to observe CO2%'s
reducing curve when infiltration rate is 0.5276 1/h (I measured the
value in the test room), so I defined the infiltration rate as 0.5276
1/h in TRNBUILD. But when I used TRNFLOW, the defined infiltration rate
as 0.5276 1/h in TRNBUILD was replaced. And 1000 ppm keeps constant.<br>
<br>
Please tell me how to get the infiltration rate curve using TRNSYS/TRNFLOW or how to explain this ?<br>
<br>
Many thanks!<br><br>br<br><br>wang<br><br><div class="gmail_quote">2011/2/21 <span dir="ltr"><<a href="mailto:trnsys-users-request@cae.wisc.edu">trnsys-users-request@cae.wisc.edu</a>></span><br><blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;">

<div>
<div>Dear TRNSYS users,</div>
<div><font face="times new roman"></font> </div>
<div><font face="times new roman">When simulating an applied thermal system, I'm using EES for the hydronic part. I programmed the hydronic circuit in EES and coupled it with TRNSYS via Type 66a. This coupling works fine, but;</font></div>
<div><font face="times new roman"></font> </div>
<div><font face="times new roman">The problem is that the simulation runs very slow. Every timestep that TRNSYS calls EES, the EES project is opened and closed. Is there a way to set some settings so EES isen't closed and reopened each time, this
would minimize the solution time alot.</font></div>
<div><font face="times new roman"></font> </div>
<div><font face="times new roman">Thanks on advance</font></div>

Dear all,<br>when entering data in Trnbuild I have to describe the walls of the zone: if, looking at the plant of the building, the building has more than a wall south oriented for example (wall to the left in the plant) <span lang="en"><span title="Fai clic per visualizzare le traduzioni alternative">I</span> <span title="Fai clic per visualizzare le traduzioni alternative">should</span> <span title="Fai clic per visualizzare le traduzioni alternative">enter in T</span><span title="Fai clic per visualizzare le traduzioni alternative">rnbuild</span> <span title="Fai clic per visualizzare le traduzioni alternative"></span><span title="Fai clic per visualizzare le traduzioni alternative">each section</span> <span title="Fai clic per visualizzare le traduzioni alternative">of</span> <span title="Fai clic per visualizzare le traduzioni alternative">wall</span> <span title="Fai clic per visualizzare le traduzioni alternative">facing south or I should enter a unique wall that is the sum of all sections of wall facing south?<br>
