<p class=MsoPlainText><span lang=EN-GB>Hi Lei<o:p></o:p></span></p>
<p class=MsoPlainText><span lang=EN-GB><o:p> </o:p></span></p>
<p class=MsoPlainText><span lang=EN-GB>This is a good question. But I think
these parameters refer the radius as explained in the proforma, because if you
see in the code, they are called R0=PAR(5), Rpo=PAR(12), Rpi=PAR(13) which
stand logically for Radius... So I just think that there is an error in the
DSTWizard.<o:p></o:p></span></p>
<p class=MsoPlainText><span lang=EN-GB><o:p> </o:p></span></p>
<p class=MsoPlainText><span lang=EN-GB>Otherwise, it is not possible to model a
double U tube heat exchanger with this Type557. I can refer you to a component
coded by TRANSSOLAR which can do that, it is called Type451. You can find the
documentation and order it on <a

<p class=MsoPlainText><span lang=EN-GB>Hi, all <o:p></o:p></span></p>
<p class=MsoPlainText><span lang=EN-GB><o:p> </o:p></span></p>
<p class=MsoPlainText><span lang=EN-GB>I have questions on the vertical U-tube
ground heat exchanger. <o:p></o:p></span></p>
<p class=MsoPlainText><span lang=EN-GB><o:p> </o:p></span></p>
<p class=MsoPlainText><span lang=EN-GB>In the parameter table, Parameters of
5(Borehole radius), 12(Outer radius of u-tube pipe), 13 (inner radius of u-tube
pipe). I think these parameters should be the radius of the Borehole and tube
pipe. But in the Plugin program DSTWizard the diagram show these value
are the diameter. Anyone call tell me these values are radius or diameter.<o:p></o:p></span></p>
<p class=MsoPlainText><span lang=EN-GB><o:p> </o:p></span></p>
<p class=MsoPlainText><span lang=EN-GB>Another question is if this model can
simulate the two U-tubes in same borehole. If it can, how to input the
parameters for the parameter 17 (Reference borehole flow). This flow is the
total flow of the two U-tubes in same borehole or just is the flow of one U-tube<o:p></o:p></span></p>
<p class=MsoPlainText><span lang=EN-GB><o:p> </o:p></span></p>
<p class=MsoPlainText><span lang=EN-GB>Thanks<o:p></o:p></span></p>
