[TRNSYS-users] About Type-952 for geothermal cooling

[David BRADLEY]

Sanjeev Jakhar,
   Type952 is intended to model a horizontal insulated buried pipe. If 
your pipes are uninsulated (and even more so if there are multiple pipes 
in parallel) then Type997 (GHP Library (TESS): Ground Heat Exchangers: 
Horizontal) is more appropriate to model use.
regards,
  David
