Exergeoconomic modeling and genetic algorithm optimization of a domestic hybrid solar lithium bromide-water absorption chiller

Exergeoconomic optimization of a dynamic single effect solar LiBr-HR2Ro absorption chiller system is performed. A model based on the energy and exergy analysis is presented. An economic model of the system is developed. As solar radiation variable is not constant in different days and months in the hot seasons of the year, the transient analysis (time dependant) is applied. The objective function based on the thermodynamic and exergeoconomic analysis is developed. The proposed single effect solar absorption cycle system includes eight decision variables is considered for optimization. A stochastic/deterministic optimization approach known as genetic algorithm is utilized as an optimization method. This approach is applied to minimize the cost of the system product.
