• The direct use of solar thermal energy to generate power produces a large amount of heat. Therefore, the use of thermally driven chillers is an appealing solution to make use of this heat to produce cooling replacing electric driven systems. The main objective of this paper is to provide a description of the possible designs and configurations of solar trigeneration systems, including organic Rankine cycles (ORC) and recently commercialized advanced absorption chillers. The main novelty of this study is the use of a Single-Effect Double- Lift absorption cycle (SE-DL AC) for solar trigeneration cycles and its comparison with a base case using a conventional single effect absorption cycle (SE AC). The main finding of this study highlights that working under the same conditions; the SE-DL AC uses heat more effectively than the SE AC for cooling production with a considerably higher production of power at the ORC.
