[TRNSYS-users] Stratified storage Tank

[Matt Duffy]

Dear Lei Wang,

I just tried this, and it simulated without problems in version 17, but
when I tried in version 16, I also received the error. I can only
speculate that this is due to the changes that we implemented for
TrnsysConstants - we increased the number of parameters.
Another option besides updating to version 17 is to use the Type534 TESS
Tank model as well. Please let me know if you have any more questions
about this.

Best regards,

Matt Duffy

Hi, All

I try to use the Type4a(stratified storage tank) to modeling the ChW
thermal storage
tank, which volume was 1 million gal and height was 100 feet.


The description of the type is as following
"The thermal performance of a fluid-filled sensible energy storage tank,
subject to
thermal stratification, can be modeled by assuming that the tank consists
of N (N <=
100) fully-mixed equal volume segments"

So I think the maximum nodes number can be 100.

But when I input the number of nodes were 100, the TrnExe shows that there
was a
range check error. When I check the list file, there didn't show any error
Information.

When I input the number of nodes were 80, it works fine.


Thanks

Lei
