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. A migratory movement connecting these wetted sectors provides for development of applicable concentration gradients between the wetted sectors along the chamber length.
