Dear Atta Ullah Sanai,
I typically make all of my external files in Microsoft Excel with
the manufacturer's data, so I can copy/paste/transpose the data.
Sometimes, I make a macro to put the data in the correct external
data file format. Please see the "04-MathematicalReference.pdf"
documentation for Type107 and the documentation of the data file
format for 'InterpolateData' in the "07-ProgrammersGuide.pdf" for
more information about this.
Please keep in mind that the default data set with Type107 is
normalized, so you might be able to set your rated capacity and
COP parameters and use that as a starting point.
Please read this for more info about normalized data.

Dear Matt,
Thanks for your response. I am still confused. Do
I have to make the external file by manually editing the example
external file available as per my requirements? How can I have
the required output values for the external file by using my own
input values if I am able to find them from a manufacturer. In
short, how can you generate an external file? Kindly help me
out. Thanks
Regards,

Dear Atta Ullah Sanai,
Thank you for contacting TESS Technical Support and
providing your institutional information. Type107 only
takes a specific set of performance data. There are a
few different TESS Chiller models in the TESS
Cogeneration and TESS HVAC Libraries as well that might
fit the particular performance data of that model. Also,
no source code compiling is necessary for the external
performance data of these components. Also, I highly
recommend that you read through the thread "Type 666
Chiller Queries" on the following page for excellent
insight about the chiller models.

Dear Sir,
We are working on a project to
simulate a solar powered vapour absorption cooling
system using TRNSYS 17. We are using type 107 for
single effect absorption chiller and are having
problems in creating an external file.
Our problem is that we are confused
how to generate an external file as per our input
values and requirements. We are working with a
Thermax LT-6 200 kW absorption chiller. Do we need
to compile the source code file to generate the
external file.
Moreover, how can we find the input
values required as they are not given by most
manufacturers.
Kindly help with this problem as soon as possible.
Thank you.
