[TRNSYS-users] External data files for heat pump & absorbtion chiller

[David BRADLEY]

Santeri,
   In my experience, it is not overly difficult to find heat pump 
performance data. Try Florida Heat Pumps (http://www.fhp-mfg.com/) as 
they have a fairly extensive line of water to water heat pumps. It is 
also nice that heat pumps normalize fairly well. That is to say that if 
you take two heat pumps and divide their performance at off-design 
conditions by the corresponding rated condition, both heat pumps will 
end up looking quite similar.

   It is, however, comparatively difficult to get data for absorption 
chillers. If you are not finding printed catalog data, you might try 
calling a manufacturer's representative; they may have access to data 
that you can use. Also more and more often manufacturers are developing 
in-house software to assist in assessing off-design performance. I have 
had some luck in getting manufacturers to let me use the software and 
then making a performance map of my own. One word of caution: absorption 
chiller performance does NOT normalize well.

Best,
David
