Hi, <div><br></div><div>I will try to ask this question once more. I know it is very specific but some of the users are working with this component so they may have an answer. </div><div><br></div><div>It´s about Type 557b "vertical GHE", parameter 11 and 12. <br>
<div><br></div><div><span style>If we set "negative pipe-to-pipe resistance" to 0, can "fluid-to-ground resistance" be compared to the effective borehole resistance as defined in the infinite line source approximation for instance? </span></div>
<div><br></div><div>I am not interested in using the other proforma "557a" because the borehole geometry (especially the shank spacing) is not controlled in my case. <br><br>Thanks in advance,</div><div><br></div>

<p>The units of thermal resistance for Parameter 11 is h.m.K/kJ. We'll update the proforma.</p><span><font color="#888888">

Have you looked through the documentation fot the model in the .\TESS Libraries\Documentation\GHP Library folder? The DST description document does a nice job explaining the thermal process used by the model.<br>

<br>Hi,
<div> </div>
<div>When using a vertical borehole heat exchanger (with known resistance), how the so-called "fluid-to-ground" resistance is defined? Practically, in the particular case of a U-tube heat exchanger, is it an "effective" thermal resistance (if there was only one tube) or the thermal resistance for a single tube? <br>
One more thing, the unit is not that clear ("any"). Is it [(m.K)/W]? <br><br>Thanks in advance, </div>
<div> </div>
<div>Have a nice day, </div>
<div> </div>
<div>Regards, <span><span><span style="color:#888888"><br clear="all"></span></span></span>
