Good question!

This is a correction to my previous post.

The You are correct that current absorption chillers (Chiller:Absorption and Chiller:Absorption:Indirect) in EnergyPlus does support both are steam driven. steam As the process is so different between the absorption and hot-water, where you can set adsorption chillers, stretching the option for the field "The Generator Heat Source Type". The "steam" word in some field names causes some confusion.

So you may want to use the performance curves for hot-water adsorption current E+ absorption chiller models to simulate its performance, but it is recommended to verify adsorption chillers should be a last solution which needs verification of the simulated results against the measured data. We will add this modeling feature to the E+ wish list. If you have data or ideas to model adsorption chillers, please let us know.

Thanks,
