<p class="MsoNormal"><span lang="EN-US">Dear Karol,<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">I have to confess that this is a little confusing.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">For better understanding of the differences of QSOLTR and QTSABS it is important to understand the considered “parts”.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">QSOLTR is the total shortwave solar radiation transmitted through all external windows
<u>including</u> shading device into the airnode.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">Then in the airnode this radiation is distributed to surfaces (taking into reflection). (For simplicity reasons we assume that there are no adjacent windows).
<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">As a results QSOLTR is either <o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">a) immediately transferred as convective heat gain to the internal air (= Qsolair, doesn’t exist in Trnsys 17) or is<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">b) absorbed by walls or<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">b) is absorbed by windows (panes, frame and internal shading devices) as radiation leaves (!) the airnode to the outside or<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">c) is transmitted to the outside (= QTSOUT, NType 73)<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">QTSABS (NType 75) consists of <o:p></o:p></span></p>
<ol style="margin-top:0cm" start="1" type="a">
<li class="MsoNormal" style="mso-list:l1 level1 lfo3"><span lang="EN-US">solar radiation is absorbed by walls and<o:p></o:p></span></li><li class="MsoNormal" style="mso-list:l1 level1 lfo3"><span lang="EN-US">the secondary heat flux of windows (panes, frame and internal shading devices) ( = QSEC, NType 56).<br>
In this case the secondary heat flux is the part of solar radiation that is absorbed by windows when solar radiation is entering
<u>and</u> leaving the airnode <br>
and going inside to the airnode.<o:p></o:p></span></li></ol>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">Thus, QSOLTR and QTSABS consider different parts of the solar radiation.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">I assume you are looking something like QSOLTR – QTSOUT.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">I hope this explanation helps.<o:p></o:p></span></p>

<p class="MsoNormal"><span lang="EN-US">I am going to find whole solar gain which come to zone throug windows.<o:p></o:p></span></p>
