<div dir="ltr"><div><div><div>Hi everyone,<br><br></div>I have some questions about the information we can find in the "WinID-Pool" tab. I don't need to go much in details, but just to have some basic information.<br>
</div>I want to compare a TRNSYS vs a CFD model of a building, and I'd like to use the same properties for my windows in both models. In my CFD calculation, my windows will be a simple 2D surface, for which I'll define absorptivity, transmissivity for visible and IR.<br>
<br></div>So, I chose a window in TRNSYS, and I see the summary in the "WinID-Pool" tab. I see that "T-vis" is the visible transmittance, while "T-sol" is the solar transmittance.<br><br><ol>
<li>Are these values for the whole window ? (ie glass+gas+glass) (U-value, g-value, etc..) ?</li><li>Is the spectral fraction of visible and IR taken as 0.5 in TRNSYS ? i.e. can I conclude from these values that IR transmittance would be (Tsol - Tvis)/0.5 ?</li>
<li>What does "Rf-sol" stands for ?</li><li>I'll also have to define values for diffuse radiation, is it equivalent to the value in the "Hemis" column that we can see in the "WinID-type" box ?</li>
</ol><p>Thank you,</p><p>Arnaud.<br></p></div>
