<p class="MsoNormal">Dear TRNSYS users, <o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I have a question regarding the calculation of the beam radiation distribution under the standard mode.
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">In TRNSYS 17’s manual, it is specified that under the standard mode for beam radiation distribution calculation, if the GEOSURF values of all surfaces of a zone are all set to 0, then “the direct radiation is distributed the same way as
the diffuse radiation (by “absorptance” weighted area ratios)”.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">But let’s suppose that I run a simulation under the detailed mode for diffuse radiation distribution and under the standard mode for beam radiation distribution with geosurf all set to 0. Does it imply that that on one hand the Gebhart
method will be applied for the diffuse part of the entering solar radiation, and that on the other hand the weighted area ratios method will be applied for the direct part? Or will the total entering solar radiation be considered as 100% diffuse and in that
case only the Gebhart method will be applied for calculating the distribution?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Thank you in advance for you responses!<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Best regards, <o:p></o:p></p>
