Open-cycle absorption air-conditioning is a promising type of solar driven cooling system. It addresses, in a significant way, the problems of high solar collector costs and power requirements that plague other solar cooling systems. Previous open-cycle absorption modeling studies have been very limited and included only the solar collection part of the system. The purpose of this study was to evaluate the critical parameters necessary in order to have a viable system and to evaluate the potential for use of this type of system in various climatic regions of the United States. This is the first study to examine this promising type of air-conditioning as a total system interacting dynamically with its environment. Mathematical analysis and computer simulation were used in the study. Thermodynamic property data were reviewed for several possible working solutions, analyzed to give predictive equations, and compiled into subprograms suited to system simulation work. The exergy concept was used to analyze the sources driving cooling systems. It was shown that an effectiveness based on exergy could be used as a thermodynamic common denominator to compare cooling systems using different driving sources, including those that utilize the evaporation of water to the atmosphere.
