<p>Dear All,<br> <br>I have some questions to ask you! Many thanks in advance!</p>

<p>What's the meaning of A,B,C,D and K? Why K has 0 1 2 3? Is it measuring times(once twice etc.) or other meanings?<br> <br>Besides that, I saw K=4 or 2 etc.</p>
<p><br>PLUS:</p>
<p>1) I designed one zone temperature control system using PID controller with DCV control strategy to control the window opening factor(OP): the set-point temperatre is 21°C when occupied, 19°C when unoccupied. But to my surprise, it needs only about 2 hours to reach 21°C from 19°C, BUT it needs 13 hours to reach 19°C from 21°C. It will have much more heating consumption in actual situation. <br>
Please explain it in detail! I think like this why the thermal time constant will change? What's relationship between the thermal time constant with 2 HOURS and 13 HOURS?</p>
<p>I attached the picture of them. Please check it!</p>
<p>2) I used NTYPE 207: FLTOZ to calculate the total outdoor air flow into zone when the window opening factor changes, Is it right? If so, which type can i use to calculate the Q of heating consumption? (dQ=dm*C*(Tindoor-Toutdoor)-->lntegral dQ?) Or how to calculate the sum of dm of indoor air flow into outside and the sum of(Tindoor-Toutdoor) one day?</p>
<p>3) To type 9: I used my own weather data every one hour. But Why the original data cann't be shown in .out file and NO .plt file after running? Because I want to use the original data.</p>
<p> <br>Many thanks!<br> <br>Br.<br> <br>wang<br><br></p>

<p class="MsoNormal">Hi,</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal"><span lang="EN-US">I’ve upgraded from CVF6 to IVF11.1, downloaded the IVF10.1 example project from TRNSYS’s website and try to debug a user component running in legacy mode (TRNSYS 16.01.0003, link to TRNDLL). TRNSYS dll is well copiled since simulations run as usual. I checked that in the project debug option manager the path to TRNExe.exe is correct: when I run the debug, I got a warning message “ debugging information for ‘TRNExe.exe’ cannot be found or does not match. Binary was not build with debugging information” and debugging failed. Can you give me any tips&tricks about how to debug under IVF11.1 ?</span></p>

Using the same source and, theoretically, the same estimation models there are big differences in the results for a tilted surface between TRNSYS and the other software we normally use, specially in winter.<br>
I´m using Type 16, reduced estimation from Reindl to calculate diffuse and beam components and Hay and Davies model for tilted surface, supposed to be what the other software use.<br>But basically I find a very little change between the two different sloped surfaces , 0º and 45º. We are supposed to get much more in percent in Winter when we have a sloped surface, don´t we?<br>
This are the results. Latitude 52º<br><br> TOTAL kWh/m2 months<br>Horizontal 1011. 18.8 32.1 67.3 112.7 152.3 150.4 160.9 135.0 86.9 56.6 24.1 14.2<br>
