Dear TRNSYS users,<br><br>I have a few questions when I use Type557b.<br><br>1. What are the specific means of Parameter 11 "Fluid to ground resistance" and Parameter 12 "Negative of pipe-to-pipe resistance"?<br>
<br>2. What I understood about these two paramters is that the total borehole resistance is calculated by paramter 11 and the absolute value of parameter 12. I don't know whether my understanding is correct or not? If my understanding is right, then how is the form of the formula that calculate the total borehole resistence and how to accurately get the values of these two parameters?<br>
<br>I appreciate your answers!<br><br>Best regard!<br><br>Dapeng Li<br>
