color:#1F497D'>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! <o:p></o:p></span></p>

<p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'><span
lang=EN-US>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. </span><o:p></o:p></p>
<p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'><span
lang=EN-US>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. </span><o:p></o:p></p>
<p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'><span
lang=EN-US>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!</span><o:p></o:p></p>
