<div class="gmail_quote"><br> I have some questions about TRNFLOW 's TEST DATA:<br>
<div>
<div class="gmail_quote"><br> <br><br>To <font face="Arial" size="2"><span>"test data" : :<br><br>1. I defined </span></font><font face="Arial" size="2"><span>"test data",</span></font> I defined initial CO2% as 1000 ppm(0.00164 kg/kg) in the test room in TRNFlow, and I defined the ambient CO2% as 400 ppm(0.00065726 kg/kg). But after running, the ambient CO2% as 400 ppm(0.00065726 kg/kg) doesn't work, the indoor CO2% reduce beyond 400 ppm(0.00065726 kg/kg) and up to 6.00E-10kg/kg, i think the air flow rate in test data works all the time, the ambient CO2% as 400 ppm(0.00065726 kg/kg) doesn't work.<br>
So I defined an Equation in simulation studio: when CONZ(the indoor CO2% )<0.00065726, air flow factor is 0. What's the meaning of air flow factor?<br> I think the above problem's reason is air flow factor(1) works all the time. Is my thought right or not? Please see the ATTACHED 1st and 2nd. Please have a look at my programs whether are they right or not? If not please correct them. thanks!<br>
<br><br><br>But after running, I found CO2% reducing rate of the curve is very faster than my actual measurement in the test room. Please see the ATTACTED 3rd and 4th. To 3rd you can see only about 2 hours the CO2% got to 400 ppm(0.00065726 kg/kg), but to 4th the actual measurement curve in the test room: it needs about 10 hours to get to 400 ppm(0.00065726 kg/kg). Please explain it, why the difference is so bigger? Or please see the ATTACHED 1st and 2nd to verify the CO2% reducing curve in TRNFlow with ATTACTED 4th the actual measurement curve.<br>
<br>2. Please tell me how to get the CO2% data etc. of TRNFlow output after running?<br><br>Many thanks!<br><br>Br.<br><br>wang<br><br><br>

<p>Dear Mr. Frenzel,<br><br> Thanks!<br><br> 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." The fact is that I defined initial CO2% as 1000 ppm(0.00164 kg/kg) in the test room in TRNFlow, and I defined the ambient CO2% as 380 ppm(0.0005819 kg/kg). 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 see the ATTACHED.<br>
<br> Please explain this! Or tell me how to define in TRNSYS/TRNFlow in order to compare the test room infiltration rate of actual measurement value with by TRNSYS/TRNFlow simulation? I want to observe CO2%'s reducing curve when infiltration rate is 0.5276 1/h (I measured the value in the test room) using TRNSYS/TRNFlow, to observe the CO2%'s reducing curve whether is the same as the actual measuring CO2%'s reducing curve or not?<br>
<br> Many thanks!<br><br> Br.<br><br>wang<br> <br><br></p>

<div class="gmail_quote"><br><br><br>
<p>Dear Mr. Frenzel,<br><br> Many thanks!<br><br> After I installed both of them once again, it's OK.<br><br>1. To radiative part: The test room has 2 heatings: one is radiator, its power is 578 W, another is convector, its power is 540 W. How can I define this situation's radiative part? As you said can I think both of them have only convective part? So I define the radiative part is 0 or not? As you know, it is very difficult to make sure what's the convective and radiative part of this test room situation. But my professor let me figure it out, so can I define the radiative part as 0? Or do you have some experience about this radiative part defining?<br>
<br>2. To thermal time constant: Thermal time constants are a feature of the <a title="Lumped system analysis" href="http://en.wikipedia.org/wiki/Lumped_system_analysis" target="_blank">lumped system analysis</a> (lumped capacity analysis method) for thermal systems, used when objects cool or warm uniformly under the influence of convective cooling or warming. In this case, the heat transfer from the body to the ambient at a given time is proportional to the temperature difference between the body and the ambient.<br>
Physically, the constant represents the time it takes the system's <a href="http://en.wikipedia.org/wiki/Step_response" target="_blank">step response</a> to reach <img alt="1-1/e \approx 63.2%" src="http://upload.wikimedia.org/math/6/7/6/6763884f1bcfc96545ad16c937ef5d3d.png"> of its final (asymptotic) value. <br>
<br>Please see ATTACHED 1st: Tset-point is 21°C from 8 am to 6 pm, other is 20°C, Thermal time constant of this test room is the time that Tindoor air gets to the 20°C +63.2%(21-20°C)=20.632°C. But this is at the situation of floor heating. I want to simulate the situation when using Radiator and Convector. <br>
Please see ATTACHED 2nd: The result is very strange. T indoor air which rises from lower temperature to higher appeares 3 jumps, this is very strange, because I closed all the windows and turned off TRNFLOW, only defined the infiltration in order to simulate the actual situation of the test room. But, meanwhile, QHeat is keeping constant.<br>
Please see the .tpf and ,bui files of ATTACHED. </p>
<div><br>Please tell me how to get the thermal time constant of the test room using TRNSYS? Or how to explain to my professor the ideal heating? <br><br><br><br></div> 3. To ideal heating: Where is this heating? Can I define its position? How is it operating or working?<span></span><span></span><span></span><br>
