Abstract: A method and apparatus for heat and mass transfer is described that is applicable to: regeneration of liquid desiccant solutions, heat pumping of humid gases, cooling and dehumidifying of gases for air conditioning, and water absorption from air. Generally, using a moving gas, at a constant pressure, a continual change in a vapor-liquid equilibrium is created between proximate but continually changing gas and liquid desiccant temperatures within an energy transferring chamber. Chamber wetting, implemented segmentedly, allows mass transfer into and from the moving gas. A forced temperature differential between heat sinks and sources causes heat transferred by means of thermally conductive barriers. Concurrent with temperature variances, the segmented wetting further allows liquid desiccant concentrations caused by evaporation or condensation, to vary between wetted sectors.

Abstract: A method and apparatus for heat and mass transfer are described using a moving gas, such as air at a constant and atmospheric pressure, to provide a continual change in a vapor-liquid equilibrium between proximate but continually changing gas and liquid temperatures within energy transferring chambers. Chamber wetting, implemented segmentedly, allows mass transfer into and from a first substance in a first chamber and a second substance in a second chamber. A forced temperature differential in each chamber causes heat transfer between chambers by means of thermally conductive petitions and by means of a heat exchanger. The heat exchanger provides for heat transfer between the first and the second substances of corresponding sectors of the first and second chambers. This heat transfer can allow condensation causing further evaporation in the corresponding chamber sector resulting in recycling of energy.

Abstract: A method and apparatus for regenerating aqueous desiccants used in liquid desiccant air conditioners is disclosed. The method and apparatus utilizes a desiccant boiler and a desiccant evaporator/steam condenser in combination with heat exchangers. The evaporator/condenser receives steam produced by the boiler to provide a reuse of heat for regeneration. The boiler and the evaporator/condenser each can provide substantially complete regeneration of a portion of the liquid desiccant.

Abstract: Method and apparatus for heat and mass transfer are described that is applicable to: concentration, crystallization, purification, fractionation, stripping, absorption, and/or heat exchange for liquid media; and temperature and humidity modification for gas media. Using a plurality of moving gas streams, comprised for example of air, at constant and generally atmospheric pressures, a continual change in a vapor-liquid equilibrium of the gas streams is created between proximate but continually changing gas and liquid temperatures within each of a plurality of heat exchange chambers. Chamber wetting, implemented segmentedly, allows mass transfer into and out of the gas streams. A forced temperature differential between chambers, caused by different temperatures of the gas streams entering the chambers or by humidity modification of these gas streams within chambers, causes heat transfer between chambers through thermally conductive partitions.

Abstract: A method and apparatus for heat and mass transfer is described that is applicable to: concentration, crystallization, purification, fractionation, stripping, absorption, and/or heat exchange for liquid media; drying for solid or gel media; and temperature and humidity modification for gas media. Generally, using a moving gas, such as air at a constant and atmospheric pressure, a continual change in a vapor-liquid equilibrium is created between proximate but continually changing gas and liquid temperatures within energy transferring chambers. Chamber wetting, implemented segmentedly, allows mass transfer into and from the moving gas. A forced temperature differential in each chamber causes heat transfer between chambers by means of thermally conductive partitons. This transfer can allow condensation causing further evaporation in the opposite chamber resulting in a recycling of energy.

Abstract: On a surface on which heat is exchanged with a gas media, the heat transfer coefficient can be enhanced by directing a spray at the surface. The spray droplets can disrupt the stagnant air layer adjacent to the exchange surface, can increase the area for heat and mass transfer and can aid in carrying vapor from the gas media to the exchange surface.
