Abstract
A desiccant air conditioning system for cooling an air stream entering a building space includes a conditioner and a regenerator. The conditioner includes structures arranged in a substantially vertical orientation that are spaced apart from each other with an air stream gap between each pair of adjacent structures. Each structure has a surface facing an air stream gap across which a liquid desiccant can flow. The air stream flows through the air stream gaps between the structures such that the liquid desiccant dehumidifies the air stream. Each structure further includes a separate desiccant collector at a lower end of the surface for collecting liquid desiccant that has flowed across the surface of the structure. The desiccant collectors are spaced apart from each other to permit airflow therebetween. A photovoltaic-thermal module heats a heat transfer fluid used to heat the liquid desiccant in the regenerator.
