<div style="direction: ltr;font-family: Tahoma;color: #000000;font-size: 10pt;">Dear all,
<div><br>
</div>
<div>I am Brembilla from Aalto University. I am a TRNSYS basic user and</div>
<div><br>
</div>
<div>I started some days ago to read the guide and I tried to do the guide examples.</div>
<div><br>
</div>
<div>In the example at the point 1.4.2.1 of the guide the Sunspace, I cannot understand</div>
<div><br>
</div>
<div>what means for backzone and sunzone. I also open the TRNbuild and I took a </div>
<div><br>
</div>
<div>look at the surfaces and the backzone surfaces are larger than sunzone.</div>
<div><br>
</div>
<div>Unfortunately there is not the 3d model so i cannot undertand how works it.</div>
<div><br>
</div>
<div>Somebody could help me?</div>
<div><br>
</div>
<div>My second problem it is regarding the example at the point 1.5, it works well.</div>
<div><br>
</div>
<div>I alsro tried to change the parameters like slope, collector surface and I can see variation</div>
<div><br>
</div>
<div>in the temperatures. I cannot understand the gist of heat transfer rate. It is an energy,</div>
<div><br>
</div>
<div>of course the energy of the heater is 1400W*3,6s=5040 kJ but I cannot understand way </div>
<div><br>
</div>
<div>it is always constant in the time schedule even else the collector already provides heat water.</div>
<div><br>
</div>
<div>It should be the difference between the 5040 kJ and the heat transfer rate provides by the collector.</div>
<div><br>
</div>
<div>Somebody could help me, please?</div>
<div><br>
</div>
<div>Thank you in advance.</div>
<div><br>
