Ali Javed,
   It is preferable to create an external data file for Type107 that 
corresponds with the actual absorption chiller that you are trying to 
analyze. However, if you do not have any such performance data then the 
sample data file associated with Type107 can be used. We did some work 
many years ago to look at what the performance curves of various pieces 
of HVAC equipment look like when you divide all of the performance 
points by their value at the rated condition. Some equipment (such as 
constant-speed compressor heat pumps) all start to look basically the 
same when their performance is normalized. Some other equipment (notably 
absorption chillers, which is why I am bothering you with this...) do 
not look similar to one another when normalized. The take-away here is 
that if at all possible, get performance data for the absorption chiller 
manufacturer and model that you are planning to use.
Best,
  David
