Beschreibung
Zusammenfassung:	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.
