[TRNSYS-users] air-to-soil heat exchanger (canadian well)

[David BRADLEY]

Issmail,

   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.

kind regards,
