%X This paper is devoted to the thermodynamic analysis and investigation of the triple effect parallel flow water/lithium bromide chiller with three condensers. For this purpose, the conservation equations governing the cycle are written and the cycle is investigated in the aspect of the first and second laws of thermodynamics. Next the thermodynamic state of various points of the cycle, cycle efficiency, work and heat transferred, and also the exergy loss in various components of the cycle are evaluated. Finally the exergy analysis is carried out and the effect of effective parameters on cycle better performance has been studied.It was concluded that when temperature of the high-temperature generator increases, the cycle COP increases and total exergy losses decrease. Though, the increase of COP and decrease of exergy losses becomes negligible for temperatures higher than 210°C. Therefore, more temperature increase does not profit considerably to increase of COP or reduction of exergy losses, and this temperature is the most optimal temperature in which both the COP and exergy losses have acceptable values.
