A liquid desiccant dehumidifier includes a liquid desiccant absorber arranged to receive concentrated liquid desiccant and absorb moisture contained in ambient air passed through the absorber thereby diluting the liquid desiccant. A first heat exchanger is operative to heat dilute liquid desiccant received from the desiccant absorber prior to passage to a boiler that evaporates moisture from the diluted liquid desiccant to create steam and reconstitute the desiccant into a concentrated liquid desiccant. Dilute liquid desiccant from the first heat exchanger first passes to a condenser that receives steam from the boiler and sensibly heats the dilute liquid desiccant to a higher second temperature without direct exposure to steam or air. A second heat exchanger communicates with the condenser, the boiler and the first heat exchanger and is operative to further heat diluted liquid desiccant received from the condenser to a higher third temperature prior to entry into the boiler by recovering waste heat from the boiler. A pump draws concentrated liquid desiccant from the boiler through the heat exchangers and passes it to the absorber.

[ What is claimed is:] [1.] A liquid desiccant dehumidifier, comprising:a liquid desiccant absorber for absorbing moisture contained in ambient air entering the dehumidifier and passing through said desiccant absorber, said desiccant absorber constructed and arranged for receiving concentrated liquid desiccant and dispensing dilute liquid desiccant, said desiccant absorber including a plurality of absorber pads disposed in upstanding side-by-side relation, said desiccant absorber further including a distributor pan disposed above said pads for distributing liquid desiccant to said pads, said absorber pads being secured together at least adjacent upper ends thereof so as to substantially prevent liquid desiccant from said distributor pan passing downwardly between said pads and thereby cause said desiccant to wick downwardly through said pads, and a drain pan disposed below said pads for collecting dilute liquid desiccant from said pads;a boiler for boiling dilute liquid desiccant to evaporate moisture to reconstitute the liquid desiccant into concentrated liquid desiccant; anda condenser fluidly communicating with said boiler to receive steam generated by boiling liquid desiccant in said boiler, said condenser further fluidly communicating with said absorber to receive dilute liquid desiccant from said absorber, said condenser being operable to sensibly heat the dilute liquid desiccant therein by recovering the latent heat of condensation as steam delivered from said boiler is condensed so as to preheat said dilute liquid desiccant prior to delivery to said boiler.
