Three ways to go about doing this, using the
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
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. 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: 1) the collectors charge a hot storage tank 2) a gas-fired auxiliary device provides backup during periods where the tank can't supply the generator with hot water 3) the absorption chiller draws from the storage tank and charges a second storage tank with chilled water for distribution to the load I think we also have a version where there isn't a second tank and the chiller feeds the load directly. Let me know if you are interested in exploring this option and good luck with your search. Jeff

I am attempting too model a building using absorption cooling, but am not sure how too do model it. Any suggestions to help me get started?
Thanks, Holly
