measurement data of the CSHPSS in Hannover-Kronsberg, where the storage volume
is 2750 m³. The conclusion is that </FONT></SPAN>30 segments give the highest
accuracy for the case given. Furthermore it is adviced not to use any
connections at the bottom segment, because this leads to an overestimation of
the heat loss rate of the storage bottom. For details you should check the
thesis.</SPAN></FONT></DIV>

parameters, but some remain very unclear, namely the value of parameter 2 :
« segments ». As the parameter’s value rises (10, 50, 100 for
example), the temperatures in the storage tend to decreases, and hence the Solar
Fraction decreases …<o:p></o:p></SPAN></FONT></P>
