In this paper, application of LiBr absorbent mixtures in absorption chillers is studied; meanwhile the thermodynamic properties effective on the performance of absorption chillers have been investigated. Considering different properties of lithium bromide and its limitations for application in absorption chillers, required additives that can be used as absorbent have been presented. Then coefficient of performance of the cycle was calculated as a criterion for optimum performance of the chiller and the mixture with maximum COP was introduced. Finally COP was optimized using sensivity analysis of effective parameters
