In my experience, it is not overly difficult to find heat pump
performance data. Try Florida Heat Pumps (<a class="moz-txt-link-freetext" href="http://www.fhp-mfg.com/">http://www.fhp-mfg.com/</a>)
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.<br>
<br>
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.<br>

I need to use a water to water ground heat pump (type 668) and
absorbtion chiller in my simulations. It seems to be very
difficult to find product catalogues that include the information
required in the external data files. Could someone with experience
please tell me which manufacturers do provide this kind of
information and perhaps send me a link. The only catalogue data
file that I was able to for water to water heat pump was this one
from Carrier:<br>
