In this work, the energetic, exergetic and exergoeconomic analysis by the SPECO method are performed. The system is a trigeneration cycle with two absorption chillers, one of single effect and other of double effect. The trigeneration system was propose for a resort at Piauí. The prime energy source is the thermal reject of a diesel engine, already existent at the resort. The thermal load provided by the chillers and the heat provided for water heating was calculated. The components with the highest exergy value destroyed of the system were identified. These components have the most cost of installation and should be optimized. Through the economic analysis, it was found that the operation of the system would be during two hours at peak hours, when the resort occupancy rate was 50% or more. In this study, was concluded that the proposed trigeneration system has a good energy and exergetic performance, but that some components should be optimized and a more detailed economic analysis should be performed.
