[TRNSYS-users] TRNSYS - External data file type 107 - Help required

[Technical Support]

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.
