EnergyPlus program which has a gas power absorption chiller routine which is all
free. Purchase Transys which has modules for simulating an absorption chiller.
Or finally refer to the post below </FONT></SPAN></DIV>

<P>We've done quite a few solar absorption modeling projects over the past 10
years or so for NREL, NRCAN and a few others but I'm not sure if the results
were ever written up into technical reports/papers. You may want to check the
NREL web site. </P>
<P>As a result of these projects, we have a software tool that can be used to
assess the potential for this technology in commercial and industrial buildings.
Because the tool is based on TRNSYS, it can also easily be modified to more
accurately reflect your particular configuration. If i remember correctly, the
program was configured to study a system where:</P>
<P>1) the collectors charge a hot storage tank</P>
<P>2) a gas-fired auxiliary device provides backup during periods where the tank
can't supply the generator with hot water</P>
<P>3) the absorption chiller draws from the storage tank and charges a second
storage tank with chilled water for distribution to the load</P>
<P>I think we also have a version where there isn't a second tank and the
chiller feeds the load directly.</P>
<P>Let me know if you are interested in exploring this option and good luck with
your search.</P>
