<div>Dear all,</div>
<div> </div>
<div> I made a small simulation compared TRNSYS with theory calculation results about QHEAT. But the QHEAT curve is a little strange. PLEASE see the ATTACHEDs 1st,2nd and 3rd which include *.tpf, *.bui and online-plotter files.</div>
<div> </div>
<div>1) Known conditions:</div>
<div>Tindoor=20C=Initial Tindoor (livingroom)</div>
<div>Toutdoor=10C=Initial Toutdoor=Tboundary walls (5 walls)</div>
<div>only one wall next to the another zone (kitchen) </div>
<div>no solar and internal etc. gains</div>
<div>no infiltration</div>
<div>Massless walls</div>
<div> </div>
<div>From the online plotter, you can see at the beginning of the QHEAT about 7 hours, it fluctuates very frequently. Please tell me some possible reasons about it! I kept Tindoor and Toutdoor as constant, why QHEAT is not a Constant?</div>
<div> </div>
<div>2) Still this simulation, I defined Mass-effect walls and without infiltration. PLEASE see the ATTACHEDs 4th, 5th and 6th which include *.tpf, *.bui and online-plotter files. </div>
<div>I compared TRNSYS with theory calculation results about QHEAT. But the TRNSYS-QHEAT result during 24h is only 6300 kJ, however, theory result is 24000 kJ. Some experts told me the reason is <font color="#000099">TRNBUILD's PROPERTIES' AVERAGE SURFACE TEMPERATURE TEMP. as 293.15K, the walls storage a lot of thermal energy, so QHEAT is 6300 kJ smaller than 24000 kJ. </font><font color="#000000">But I changed it as 283.15 K the same as Toutdoor, however, the result is still 6630 kJ. So I'm confused. Please tell me some possible reasons about it! BUT I simulated during one month, the result is 30*23951 kJ, it seems the similar to the theory result 24000 kJ. What're the reasons about it?</font></div>
<div> </div>
<div>These two questions FEAZE me about more than 6 months, so please help me£¡ </div>
<div> </div>
<div>Mant thanks in advance!</div>
