Absorption cooling systems provide sustainable solutions to make renewable potential energy sources, such as solar energy or biomass energy, usable. These systems operate with eco-friendly working fluids and offer a significant reduction in electricity consumption compared to vapor compression cooling technologies. Absorption cooling systems are classified into single-effect, double-effect, and triple-effect types, with triple-effect systems achieving the highest efficiency. Furthermore, in addition to these three groups, half-effect and quadruple-effect systems, which have been relatively less explored in the literature, have also been designed. However, the increased thermodynamic complexity and the larger number of components in triple-effect systems pose significant technical and economic challenges. This review systematically categorizes research on triple-effect absorption cooling systems into five key areas: studies on specific configurations, comparative analyses, investigations of different configurations, hybrid systems integrating other thermodynamic cycles, and experimental/commercial developments. The analysis highlights emerging trends, such as the integration of triple-effect systems with hybrid cycles (e.g., organic Rankine and Kalina cycles) to enhance energy efficiency, and identifies gaps in experimental validation and commercial deployment. By addressing these challenges and opportunities, this paper underscores the potential of triple-effect absorption systems to expand their role in high-efficiency cooling applications, particularly when combined with renewable and waste heat energy sources. Future research directions are suggested to promote broader adoption and commercialization of these systems.
