Abstract

A desiccant air conditioning system for heating an air stream entering a building space includes a conditioner having multiple structures arranged in a substantially vertical orientation. The structures are spaced apart from each other with an air stream gap between each pair of adjacent structures. Each structure has at least one outer surface facing an air stream gap across which a liquid desiccant can flow. 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. The desiccant collectors are spaced apart from each other to permit airflow therebetween. The conditioner also includes a heat source for heating a heat transfer fluid used to heat the liquid desiccant.
