Desiccant air conditioning methods and systems

The present invention relates to a desiccant air conditioning system for treating an air stream entering a building space. The system comprises 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 includesmultiple 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. 本发明涉及种处理进入建筑物空间中的空气流的干燥剂空气调节系统，其包括经配置以使所述空气流暴露于液体干燥剂以使得所述液体干燥剂在暖和天气操作模式下将所
