Exergoeconomic analysis of double effect absorption refrigeration systems

Exergoeconomic analyses are reported for three classes of double effect LiBr/water absorption refrigeration systems in order to investigate the influence of various operating parameters on investment costs of the overall systems and product cost flow rates. In addition, the contributions of component costs to the overall costs are obtained for each system and the results of the exergoeconomic analyses of the systems are described. The results reveal the advantages and disadvantages of different configurations of double effect LiBr/water absorption refrigeration systems from an exergoeconomic point of view and are expected to be useful in the selection, design and modification of the structure and operating parameters of such systems.

► We analyze double effect absorption refrigeration systems exergoeconomically. ► We study the effect of operating conditions on thermoeconomic parameters of the systems. ► We calculate the heat transfer coefficients in different components of the systems. ► In the systems the evaporator and the absorber are the most expensive components.
