Abstract: A three-way heat exchanger for a liquid desiccant air-conditioning system and method of manufacture. The heat exchanger includes a plurality of panel assemblies. Each panel assembly has a frame bordering a given space. The frame includes desiccant inlet and outlet ports and heat transfer fluid inlet and outlet ports. Two plates joined to the frame define a heat transfer fluid channel in the given space. The heat transfer fluid inlet and outlet ports are in fluid communication with the heat transfer fluid channel. Microporous sheets cover the outer surfaces of the plates and define a desiccant channel. The desiccant inlet and outlet ports are in fluid communication with the desiccant channel. The plurality of panel assemblies have a stacked arrangement such that a microporous sheet on one panel assembly faces a microporous sheet on an adjacent panel assembly and defines an airflow channel therebetween.

Abstract: A liquid desiccant air conditioning system includes one or more liquid desiccant tanks.

Abstract: A liquid desiccant air-conditioning system provides a uniform liquid desiccant flow distribution and wetting out of membranes used in the membrane-modules of the system.

Abstract: This application relates generally to liquid desiccant air conditioning (LDAC) systems and, more specifically, to liquid desiccant air-conditioning systems configured to use antifreeze-free heat transfer fluids.

Abstract: A three-way heat exchanger includes multiple panel assemblies that are stacked into a block and supported in a housing structure. Each panel assembly includes a frame and two plates joined on opposite sides of the frame. A method of manufacturing the three-way heat exchanger is also disclosed.

Abstract: Methods and control systems are disclosed for operating a liquid desiccant air-conditioning system to efficiently maintain a target temperature and humidity level in a space.

Abstract: A liquid desiccant air-conditioning system provides a uniform liquid desiccant flow distribution and wetting out of membranes used in the membrane-modules of the system.

Abstract: Liquid desiccant air conditioning methods and systems are operable in multiple modes to efficiently treat air streams provided to a space.

Abstract: A method of manufacturing a heat exchanger, include the steps of: (a) providing two plates configured to be assembled together, each of the plates comprising a support layer and a cap layer laminated over the support layer at least at a front side of the plate; (b) heat bonding a microporous membrane layer to one or more select portions of the cap layer on the front side of each plate such that a liquid desiccant channel is formed between the membrane layer and the front side of each plate; and (c) attaching the front sides of the plates together to form a plate pair structure by heat bonding one or more select portions of the cap layers on the front sides of the plates such that the membrane layers on the plates face each other and an air flow channel is formed between the membrane layers.
