<b>Betreff:</b> [TRNSYS-users] Thermal mass of glazings<o:p></o:p></span></p>
</div>
</div>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"><span lang="FR">Hello everyone,<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="FR"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">As I am conducting thermal simulation in a high glazed zone (conservatory), I am concerned about thermal mass of glazings. According to the documentation, thermal mass is set as null for glazings.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">But, after a hard work of fitting between my simulation model and some experimental data, I noticed that my simulation model is “lighter” than the experimental one (air temperature variates more reactively in simulation).<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">So, I calculated the thermal mass of all inner glazings (well I approximated it) and added the result to the zone capacitance. The result is very encouraging and I’m quite happy with the simulation model as it is set
now. However, I would like to have your feedback on this. What would be your judgment on this method as thermal experts and is there another way to add a thermal mass to the glazings ?
<o:p></o:p></span></p>

<p class="MsoNormal"><span lang="EN-GB">Best regards<o:p></o:p></span></p>
