Abstract
A desiccant air conditioning system for treating an air stream entering a building space, including a conditioner configured to expose the air stream to a liquid desiccant such that the liquid desiccant dehumidifies the air stream in the warm weather operation mode and humidifies the air stream in the cold weather operation mode. The conditioner includes multiple plate structures arranged in a vertical orientation and spaced apart to permit the air stream to flow between the plate structures. Each plate structure includes a passage through which a heat transfer fluid can flow. Each plate structure also has at least one surface across which the liquid desiccant can flow. The system includes a regenerator connected to the conditioner for causing the liquid desiccant to desorb water in the warm weather operation mode and to absorb water in the cold weather operation mode from a return air stream.
