Dears all,
I'm using the type 655 "chilled
water flow rate" from TESS library. First, I noticed an
inversion between CAPACITY ratio and COP ratio in the
external file (containing the chiller performance data).
Secondly, here my problem; this type
do not consider the ambient temperature in the chiller
capacity and COP calculations. In fact, this model always
choose CAP and COP ratio values corresponding to the highest
ambient temperature for a chilled water temperature. So,
have you got an idea about how can I figure out this issue?
Thanks you

Dear Luis
Carlos Vela,
That is fixed for TESS Libraries version 17.01 (you may see
the version of the TESS Libraries that you have by viewing the
names of their external DLL's in the ".\UserLib\ReleaseDLLs"
directory or by looking at the 'Readme.html' file in the
".\Tess Models" directory). Thus, please make sure that you
are using that version.
Best regards,
Matt Duffy

(chilled water flow rate)
My name is Luis Carlos Vela
colmbiano am a college student and
Francisco José de Caldas District, has
the license lacual TRNSYS V17. I am
currently developing my graduation
project and I have questions,
TranSys attached

when I choose the type chiller
655 and I will enter the input data see
the following problem.
Water chiller units
are degrees Celsius flexible rate, so my
question is what units should I enter in
this box as Celsius tablets are not
units! of flow.
