Abstract

A desiccant air conditioning system treats an air stream entering a building space. The system includes a conditioner having multiple structures arranged in a substantially vertical orientation, each having at least one surface across which a liquid desiccant can flow. The air stream flows through or between the structures such that the liquid desiccant dehumidifies the air stream in a warm weather operation mode and humidifies the air stream in a cold weather operation mode. Each structure further includes a 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 structure. A regenerator receives liquid desiccant from the desiccant collectors in the conditioner and causes the liquid desiccant to desorb water in the warm weather operation mode and to absorb water in the cold weather operation mode.
