Nicolàs, from personal experience and the number of
related
posts to this list, I think anyone who uses this type encounters the
same
difficulty and confusion! Personally, under time pressure, I used two
approaches.
The first is to create a very poor approximation by simply using the
data file
provided or creating a simpler data file with constant performance over
a wide
range of data. The data file format itself isn’t that complicated (two
four-variable
functions). The second approach that I am currently trying is to model
the generator,
absorber, and cond/evap coils with the auxiliary heater/cooler types
(Type 92, 6).
It would be extremely useful to have an a wider range of data files, a
simpler
chiller model, or at least a walkthrough of creating a data file, at
least to
get something in the right order of magnitude as a first approximation
. Hint
hint @ developers!
Sorry I can’t help more,

Dear TRNsys users,
I have a problem
with type 107, the absorption chiller. In the Data
file folder of TRNsys installation there is only one data file which
can be
used with this type. The problem is that I need to utilize the hot
water with a
temperature in a different range, and not only between 108.89 and
116.11 °C ,
the range of the data available.
Should I use data
available on the internet? And if so, What’s
the procedure to use them? I checked in the Mathematical reference but
it is
not so clear.
If someone of you
could give me some help, I would be really
grateful , because I need to use this file for my master thesis ( upon
solar
cooling) and I don’t have so much time!
