A triple-effect cycle is disclosed which avoids the two primary limitations of currently known triple-effect cycles: super-atmospheric pressures and/or low pressure absorbers that operate without mass transfer enhancers. The cycle is comprised of two hermetic loops - one a conventional LiBr double-effect loop, and the other a single-effect loop which overlaps the high pressure portion of the double effect loop, and exchanges heat with it at three locations. Referring to the figure, the latent heat exchanges are with absorber (302), condenser (304), and evaporator (305) of the single-effect loop. Sensible heat losses are reduced by incorporating inter-loop condensate-to-solution sensible heat exchanger (314). The inter-loop CSSHX also applies to other triple-effect cycles. |
