[TRNSYS-users] TESS thermal storage tank

[David BRADLEY]

Pouyan,

   Types 534 and 158 are quite similar mathematically. Type534 offers a 
lot more flexibility than Type158 offers. The idea in developing Type158 
was to make a simplified version of Type534 that intentionally did not 
offer so many options so that users would not get confused by all of the 
different parameters and possibilities.

   For your other questions, if you have not already done so, I would 
recommend referring to the documentation for each of the two models. The 
documentation on Type158 can be found in the 
04-MathematicalReference.pdf manual in .\Trnsys18\Documentation\ and the 
documentation on Type534 can be found in .\Trnsys18\Tess 
Models\Documentation\11-StorageTankLibraryMathematicalReference.pdf

kind regards,

  David
