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.
