The increasing awareness about energy conservation and its implications for a company's profitability has led to the creation of several models that combine energy processes with cost-accounting methods. Consequently, the industry has centered its endeavors on identifying economically viable, technologically possible, and environmentally acceptable alternatives. An approach to addressing the above issues is to conduct an exergoeconomic analysis of the energy systems implemented during operations to maximize resource use. The present research evaluates the use of exergonomic analysis in an Absorption Heat Transformer (AHT) to identify areas for improvement in system operation and to optimize the essential parameters for improved technological efficiency. The study also found possible ways to make the generator (GE), economizer (EC), and absorber (AB) better for future research, while still reaching up to 98% technical efficiency in some parts. Considering cost as a measure of used resources provides a thorough insight into the energy systems adopted by the industry. Thanks to the fact that exergonomics considers costs as a measure of resource consumption, this approach offers a comprehensive view of the energy systems adopted by the industry. These results are relevant for understanding the potential impact of integrating technical, economic, and environmental efficiency into energy management practices within the industrial sector.
