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

Dear all,
Does anyone can help me
about the differnce between the vertical cylinder thermal
storage tank without plug-in in TESS library (Type 534) and
noral thermal storage tank (Type 158)? Which one is more
accurate to use? and what is the heat loss coeficient since
the defult value is 2.5 kJ/h.m2.K in Type 158 and
5 kJ/h.m2.K in type 534?
In addition, in Type 534,
what is the gas flue in the storage tank? Is it related to
the gas flue from the boiler?
Thanks in advance
Pouyan
