Zusammenfassung:	A liquid desiccant air conditioner includes an absorption air conditioner (202) and a liquid desiccant dehumidifier (200). The dehumidifier includes a liquid desiccant absorber for absorbing moisture contained in ambient air entering the dehumidifier, a boiler (34) for boiling partially preheated dilute liquid desiccant to evaporate moisture to reconstitute the liquid desiccant into concentrated liquid desiccant, a first heat exchanger (66) operable to transfer heat from the concentrated liquid desiccant to dilute liquid desiccant received from the desiccant absorber (12) so as to raise the temperature of the dilute liquid desiccant to a first temperature, a condenser (86) operative to receive partially heated dilute liquid desiccant from the first heat exchanger (66) and receive steam generated by the boiler (34) so as to sensibly heat the dilute liquid desiccant to a second temperature, and a second heat exchanger (58) operable to transfer heat from concentrated liquid desiccant to the dilute liquid desiccant received from the condenser so as to 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 (34) and the concentrated liquid desiccant from the second heat exchanger is directed to the first heat exchanger. A pump (80) 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 (202). L'invention concerne un climatiseur à déshydratant liquide composé d'un climatiseur à absorption (202) et d'un déshumidificateur à déshydratant liquide (200). Le déshumidificateur est composé d'un déshydratant liquide destiné à absorber l'humidité contenue dans l'air ambiant pénétrant dans le déshumidificateur, d'un bouilleur (34) destiné à faire bouillir un déshydratant liquide dilué, partiellement préchauffé, afin de faire évaporer l'humidité en vue de reconstituer le liquide en déshydratant liquide concentré, d'un premier échangeur thermique (66) pouvant transférer de la chaleur du déshydratant liquide concentré vers le déshydratant liquide dilué obtenu à partir de l'absorbeur à déshydratant (12) de manière à élever la température du déshydratant dilué à une première température, d'un condenseur (86) pouvant recevoir du déshydratant dilué partiellement chauffé à partir du premier échangeur thermique (66), et recevoir de la vapeur produite par le bouilleur (24
