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:] [30.] A liquid desiccant dehumidifier comprising, in combination:a liquid desiccant absorber for absorbing moisture contained in ambient air passing through said desiccant absorber, said desiccant absorber being operative to receive concentrated liquid desiccant and dispense dilute liquid desiccant, a boiler for receiving and boiling dilute liquid desiccant to evaporate moisture and generate steam therefrom so as to reconstitute the liquid desiccant into concentrated liquid desiccant;a first heat exchanger adapted to receive dilute liquid desiccant from said desiccant absorber and transfer heat to said dilute liquid desiccant from concentrated liquid desiccant so as to raise the temperature of the dilute liquid desiccant to a first temperature;a condenser communicating with said boiler and said first heat exchanger so as to receive steam generated by said boiler and dilute liquid desiccant from said first heat exchanger at substantially said first temperature, said condenser being operative to sensibly heat the dilute liquid desiccant therein to a second temperature by subjecting said dilute liquid desiccant to latent heat resulting from condensation of steam received from said boiler without directly exposing said dilute liquid desiccant to air,a second heat exchanger communicating with said condenser, said boiler and said first heat exchanger, said second heat exchanger being operative to receive concentrated liquid desiccant from said boiler and transfer heat to dilute liquid desiccant received from said condenser so as to raise the temperature of the dilute liquid desiccant to a third temperature, said dilute liquid desiccant at the third temperature being directed to said boiler, and said concentrated liquid desiccant from said boiler being directed to said first heat exchanger, said second heat exchanger being disposed with respect to said boiler to recover waste heat from said boiler; andmeans for pumping concentrated liquid desiccant into said absorber.
