Abstract:
A liquid desiccant air conditioner, comprising, in combination,a dehumidifier including a liquid desiccant absorber for absorbing moisture contained in ambient air entering the dehumidifier and passing through said desiccant absorber, said desiccant absorber being constructed and arranged for receiving concentrated liquid desiccant and dispensing dilute liquid desiccant;a boiler operative at or greater than atmospheric pressure to boil dilute liquid desiccant to evaporate moisture and thereby reconstitute the liquid desiccant into concentrated liquid desiccant;a first condenser fluidly communicating with said boiler to receive steam generated by boiling liquid desiccant in said boiler, said first condenser further fluidly communicating with said absorber to receive dilute liquid desiccant from said absorber, said first 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, to preheat said dilute liquid desiccant prior to delivery to said boiler;a second condenser;an evaporator through which a refrigerant is passed to effect cooling of dehumidified ambient air from said desiccant absorber passing through said evaporator and create vaporized refrigerant;a refrigerant absorber fluidly communicating with said evaporator to receive vaporized refrigerant from said evaporator, said refrigerant absorber containing an absorbent for absorbing the vaporized refrigerant;a regenerator for separating refrigerant from the absorbent, said regenerator fluidly communicating with said second condenser to supply separated refrigerant to said second condenser, said regenerator fluidly communicating with said refrigerant absorber to receive a solution of absorbent and refrigerant from said refrigerant absorber and return absorbent from said regenerator to said refrigerant absorber, said regenerator fluidly communicating with said boiler to receive steam from said boiler as a heat input; anda pump for pumping the solution of absorbent and refrigerant from said refrigerant absorber to said regenerator.
