Claim:
1. A desiccant air conditioning system for heating an air stream entering a building space, comprising: a conditioner including a plurality of structures arranged in a substantially vertical orientation, said structures being spaced apart from each other with an air stream gap between each pair of adjacent structures, each structure having at least one outer surface facing an air stream gap across which a liquid desiccant can flow, wherein an air stream flows through the air stream gaps between the structures such that the liquid desiccant humidifies the air stream, each structure further includes a separate desiccant collector at a lower end of the at least one outer surface for collecting liquid desiccant that has flowed across the at least one outer surface of the structure, said desiccant collectors being spaced apart from each other to permit airflow therebetween, said conditioner further comprising a heat source for heating a heat transfer fluid used to heat the liquid desiccant; a regenerator for receiving liquid desiccant from the conditioner, humidifying the liquid desiccant, and returning the liquid desiccant to the conditioner; a heat exchanger connected between the conditioner and the regenerator for transferring heat from the liquid desiccant flowing from the conditioner to the regenerator to the liquid desiccant flowing from the regenerator to the conditioner; an apparatus for circulating the liquid desiccant between the conditioner and regenerator.
