<p>Issmail,</p>
<p> The algorithms that Type556 used were found to be faulty. The
component was replaced with Type952 in a later TESS Libraries
release. The component is in the GHP library. I would, however,
caution you about using either one of them to model an air-to-soil
heat exchanger. They both assume that the pipes are liquid filled
and neither one of them deals with condensation that might occur
if they were filled with air. Instead, I would recommend that you
look at Transsolar's Type460, which is specifically intended to
model an air-to-soil heat exchanger.
