Claim Text:
1. An air-conditioning system for treating air in spaces within a building, comprising: a plurality of in-ceiling units, each installed in the building for treating air in a space in the building, each in-ceiling unit comprising a conditioner including a plurality of structures arranged in a substantially vertical orientation, each of the structures having at least one surface across which a liquid desiccant can flow and an internal passage through which a heat transfer fluid can flow, each of the structures further including a separate desiccant collector at a lower end of the at least one surface for collecting liquid desiccant that has flowed across the at least one surface of the structures, said desiccant collectors being spaced apart from each other to permit airflow therebetween, each in-ceiling unit also comprising a fan or blower for flowing an air stream from a space in the building between the structures of the conditioner, wherein the air stream is cooled and dehumidified, and then transferring the air stream to a space in the building; a liquid desiccant regeneration system connected to each of said in-ceiling units configured to concentrate the liquid desiccant received from the in-ceiling units, and to supply concentrated liquid desiccant to the in-ceiling units; and a cold source connected to each of said in-ceiling units configured to cool the heat transfer fluid.
