Hello,
SAM only models electric power generation systems, so it does not include a model for absorption chillers. For the CSP models, you can use the thermal output of the solar collector or receiver as input to a separate model outside of SAM. SAM does not model the generator explicitly. The model is based on a system with an induction generator with a conversion efficiency of about 95%. For details about SAM's dish Stirling model, please see Fraser (2008), available for download on the Performance Model Documentation page of this website, under "Dish Stirling":
