摘要： A split liquid desiccant air conditioning system for cooling and dehumidifying an air stream flowing into a space in a building. The split liquid desiccant air conditioning system comprises a conditioner located inside the building, said conditioner including a plurality of first structures arranged in a substantially vertical orientation, each structure having at least one surface across which a liquid desiccant can flow, each structure also including a passage through which a heat transfer fluid can flow, wherein the air stream flows between the structures such that the liquid desiccant dehumidifies and cools the air stream, the conditioner further comprising a sheet of material positioned proximate to the at least one surface of each structure between the liquid desiccant and the air stream, said sheet of material permitting transfer of water vapor between the liquid desiccant and the air stream. The split liquid desiccant air conditioning system further comprises a regenerator located outside the building connected to the conditioner by liquid desiccant pipes for exchanging liquid desiccant with the conditioner, said regenerator including a plurality of second structures arranged in a substantially vertical orientation, each structure having at least one surface across which the liquid desiccant can flow, each structure also including a passage through which a heat transfer fluid can flow, said regenerator causing the liquid desiccant to desorb water to an air stream flowing through the regenerator. The split liquid desiccant air conditioning system yet further comprises an indirect evaporative cooling unit coupled to the conditioner for receiving the heat transfer fluid that has flowed through the first structures and a portion of the air stream that has been dehumidified and cooled by the conditioner, said indirect evaporative cooling unit including a plurality of third structures arranged in a substantially vertical orientation, each structure having at least one surface across which water is flowed, each structure also including a passage through which the heat transfer fluid from the conditioner is flowed, wherein the portion of the air stream received from the conditioner flows between the structures such that the water is evaporated by the air stream, resulting in cooling of the heat transfer fluid which is returned to the conditioner, and wherein the air stream treated by the indirect evaporative cooling unit is exhausted to the atmosphere. The split liquid desiccant air conditioning system further comprises an apparatus for moving the air stream through the conditioner and the indirect evaporative cooling unit, an apparatus for circulating the liquid desiccant through the conditioner and regenerator, and an apparatus for circulating heat transfer fluid through the conditioner and the indirect evaporative cooling unit; and a heat source for heating the heat transfer fluid in the regenerator.

摘要： A desiccant air conditioning system for treating an air stream entering a building space, the desiccant air conditioning system being switchable between operating in a warm weather operation mode and in a cold weather operation mode The conditioning 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 including a plurality of plate structures arranged in a vertical orientation and spaced apart to permit the air stream to flow between the plate structures, each plate structure including a passage through which a heat transfer fluid can flow, each plate structure also having at least one surface across which the liquid desiccant can flow, each plate structure further comprising a membrane positioned proximate the at least one surface of the plate structure between the liquid desiccant and the air stream. The conditioning system also comprises a fan positioned at an outlet of the conditioner for applying negative pressure to the conditioner to draw the air stream through the conditioner. The conditioning system further comprises a regenerator connected to the conditioner for receiving the liquid desiccant from the conditioner, said regenerator 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. The conditioning system yet further comprises a liquid desiccant loop for circulating the liquid desiccant between the conditioner and the regenerator, a reservoir coupled to the liquid desiccant loop for collecting liquid desiccant flowing from the conditioner, a vertical tube proximate a desiccant entry port at a plate structure in the conditioner coupled to the liquid desiccant loop to detect flow of liquid desiccant to the conditioner based on the height of the liquid desiccant in the vertical tube and an overflow tube coupling an upper end of the vertical tube to the reservoir to inhibit application of excessive pressure by the liquid desiccant on the membranes in the conditioner. The conditioning system further comprises a heat source or cold source system for transferring heat to the heat transfer fluid used in the conditioner in the cold weather operation mode, for receiving heat from the heat transfer fluid used in the conditioner in the warm weather operation mode, for transferring heat to the heat transfer fluid used in the regenerator in the warm weather operation mode, or for receiving heat from the heat transfer fluid used in the regenerator in the cold weather operation mode. The conditioning system yet further comprises a conditioner heat transfer fluid loop for circulating heat transfer fluid through the conditioner and exchanging heat with the heat source or cold source system and a regenerator heat transfer fluid loop for circulating heat transfer fluid through the regenerator and exchanging heat with the heat source or cold source system.

摘要： A heat exchanger for use in a desiccant air conditioning system is described. The heat exchanger comprises: a plurality of membrane-plate assemblies facing each other in a generally parallel arrangement and being spaced apart to define air gaps therebetween through which air to be treated by the desiccant air conditioning system can flow, each of said membrane-plate assemblies comprises: (a) a plate structure, (b) two membranes, each facing an opposite side of the plate structure and spaced apart from the plate structure to define a gap therebetween through which a liquid desiccant can flow, (c) at least one desiccant drain port, and (d) a siphoning drain, wherein liquid desiccant flows through the at least one drain port to the siphoning drain, thereby creating a negative pressure in the gap between each membrane and the plate structure.
