<font size="4">Dear all,<br><br>I have some questions about Energy balance for one zone (Ntype 904).<br><br>1)
For Qtrans, it might be stored thermal energy (>0?) in the wall or
directly transmitted (<0?) through the wall. But I want to calculate
the two parts exactly, i.e. how to calculate the part of stored thermal
energy in the wall and directly transmitted energy, separatedly?<br>
<br>2) For Qsolgain, does it mean Ntype 14 +15? or only Ntype 75?<br>What relationship between Qsolgain and Solar_rad. (kWh) in T56_stdoutput.sum file? Are both the same? or included relationship?<br><br>3) For Qgint, is it Ntype 7 + 13? Is it equal to Int_gains in T56_stdoutput.sum file?<br>
<br>4) I want to calculate Heat Loss (or energy consumption) in a zone
e.g. in winter, whether or not the heat loss includes Qinf + Qvent
+DQairdt+ Qtrans (only the part of directly transmitted through the
wall, not the part of stored part, that is why I ask 1))?<br>
<br>For the actual heat gain e<font size="4">.g. </font>in winter in one zone, it only includes Qgint + Qsolgain?<br><br>However, Qheat and Qcool should be Heat loss or heat gain?<br><br>Many thanks in advance!<br>Br.<br>
