[TRNSYS-users] Type 697 Data File

[David BRADLEY]

Esteban,
   I have had some success in contacting manufacturer's representatives 
and asking them to generate a few additional performance points. These 
days more and more manufacturers rely on software to generate 
performance estimates rather than on catalogs so it is hard to find a 
complete map in *.pdf form!

  If that tactic does not work then you may be able to use the example 
data file for your off-design points. Some HVAC equipment normalizes 
very well; in other words if you look at the performance of an air 
cooled chiller at a given operating point divided by the performance at 
the rated point, it looks quite the same as a lot of other air cooled 
chillers and even like other sizes of air cooled chiller. Other HVAc 
equipment does not normalize so well (absorption chillers are a good 
example). I have never looked directly at cooling coils so I am afraid 
that I can't offer any very specific advice there.
Kind regards,
  David
