[TRNSYS-users] Type 107 hot water absorption chiller- catalogue to develope a data file

[David BRADLEY]

Mehdi, Javier, and Jochen,
   I have run into the same trouble with manufacturers as well. I have 
the impression that they are moving away from printed catalogs with 
standard operating points and they are moving towards developing their 
own in-house software tools that make a machine selection based on 
expected operating points. If you (or the manufacturer's rep) run that 
software enough times with different operating points covering the 
entire range of expected inlet conditions, you can generate that 
necessary maps. Getting access to that software is nearly impossible though.
Best,
  David
