[TRNSYS-users] Imposed ground temperature for "buried pipe" types

[David BRADLEY]

Cristi,
   The Type31 "simple buried pipe" in Trnsys16 was no different than the 
standard Type31 that is in the standard Hydronics library in both 
Trnsys16 and Trnsys17. The only difference was in the proforma, which 
had a modified icon and in which the third input was labeled "ground 
temperature" instead of "environment temperature." You can continue to 
use type31 in Trnsys17. Please be aware, though that the ground 
temperature around the Type31 pipe will not be affected in any way by 
the energy transfer between the ground and the pipe.
Best,
  David
