This paper presents the exergoenvironment analysis of the developed desiccant-based air-conditioning system subjected to different regeneration temperatures. Exergoenvironment is a new evaluation tool combining the exergetic and life-cycle analyses to determine the environmental effect of the system's components and the energy utilized for the system's operation. The different materials in the manufacture of the system's components and sources of energy to operate the system have different environmental impacts. The results of the study show the system components exergy efficiency, system exergy destruction, relative environmental impact difference and exergoenvironmental impact factor which are important parameters for this analysis. It shows that some components need exergy performance improvements through replacement with high efficiency components to minimize environmental impact. Based on the results, application of the exergoenvironmental analysis is an important tool for knowing the environmental impact of the system components and its operation. The method is important in desiccant air-conditioning systems in which different materials of the components and energy are utilized for the system design and operation.
