Abstract

A desiccant air conditioning system for treating an air stream entering a building space includes a conditioner, an air treatment unit, and a regenerator. The air treatment unit acts as an evaporative chiller in a warm weather operation mode to cool heat transfer fluid used in the conditioner. The evaporative chiller receives at least a portion of a dehumidified air stream exiting the conditioner and heat transfer fluid from the conditioner, and causes the portion of the dehumidified air stream to absorb water from a water source and thereby cool the heat transfer fluid. The regenerator receives liquid desiccant from the conditioner and absorbs water from the liquid desiccant.
