摘要： 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.

摘要： A liquid desiccant air conditioner includes an absorption air conditioner and a liquid desiccant dehumidifier. The dehumidifier includes a liquid desiccant absorber for absorbing moisture contained in ambient air entering the dehumidifier, a boiler for boiling dilute liquid desiccant from the absorber to evaporate moisture and reconstitute the dilute liquid desiccant into concentrated liquid desiccant. A first heat exchanger receives dilute liquid desiccant from the absorber and is operative to heat the dilute liquid desiccant prior to passage to a condenser that receives steam from the boiler and sensibly heats the dilute liquid desiccant therein without direct contact with air, thereby eliminating desiccant carryover from the condenser. A second heat exchanger is operable to transfer heat from concentrated liquid desiccant received from the boiler to preheated dilute liquid desiccant received from the condenser prior to entry into the boiler. The second heat exchanger also recovers waste heat from the boiler. A pump draws concentrated liquid desiccant through the heat exchangers into the absorber. A portion of the steam from the boiler is used to regenerate refrigerant in the absorption air conditioner.

摘要： A liquid desiccant air conditioner includes an absorption air conditioner and a liquid desiccant dehumidifier. The dehumidifier includes a liquid desiccant absorber for absorbing moisture contained in ambient air entering the dehumidifier, a boiler for boiling partially preheated dilute liquid desiccant to evaporate moisture to reconstitute the liquid desiccant into concentrated liquid desiccant, a first heat exchanger operable to transfer heat from the concentrated liquid desiccant to dilute liquid desiccant received from the desiccant absorber so as to raise the temperature of the dilute liquid desiccant to a first temperature, a condenser operative to receive partially heated dilute liquid desiccant from the first heat exchanger and receive steam generated by the boiler so as to sensibly heat the dilute liquid desiccant to a second temperature, and a second heat exchanger operable to transfer heat from concentrated liquid desiccant to the dilute liquid desiccant received from the condenser so as raise the temperature of the dilute liquid desiccant to a third temperature. The dilute liquid desiccant at the third temperature is directed to the boiler and the concentrated liquid desiccant from the second heat exchanger is directed to the first heat exchanger. A pump draws concentrated liquid desiccant from the boiler into the absorber. Steam from the boiler is also used to regenerate the refrigerant in the absorption air conditioner.

摘要： 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.
