Abstract
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 FIG. 3, 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.
