<div>Dear Mr. Bradley,</div>
<div> </div>
<div> Thanks for your reply!</div>
<div> </div>
<div> But 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>
</div>
<div> The fact is that I defined initial CO2% as 1000 ppm in the test room in TRNFlow, and I defined the ambient CO2% as 380 ppm. Meanwhile, I defined the infiltration rate as 0.5276 1/h in TRNBUILD. I want to compare the CO2% reducing curve in the test room based on the infiltration rate 0.5276 1/h of actual measurement value with by TRNSYS simulation. But when I used TRNFLOW, the defined infiltration rate as 0.5276 1/h in TRNBUILD was replaced maybe. 1000 ppm in the test room keeps constant. Please explain this! Or tell me how to compare the test room infiltration rate of actual measurement value with by TRNSYS/TRNFlow simulation?</div>
<div> </div>
<div> </div>
<div> Many thanks!</div>

<div bgcolor="#ffffff" text="#000000">Wang,<br> TRNBuild offers an output (NTYPE96) which is the air change rate of infiltration. TRNBuild also offers an output for the energy gain (or loss) from infiltration (NTYPE4)<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><br><br>

<div>
<div>Dear TRNSYS users,</div>
<div> </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> </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> </div>
<div><font face="times new roman">Thanks on advance</font></div>
<div> </div>
