Abstract
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.
