Abstract: An apparatus harvests latent energy and water by adiabatically decompressing a controlled volume of atmospheric air to lower its pressure and temperature below the saturation point of included water vapor, thus causing the water vapor to change state to nonvaporous water and release to the decompressed air thermal energy associated with the change of state. The apparatus then extracts the nonvaporous water, leaving the released thermal energy in the decompressed air. The apparatus then recompresses the decompressed air, which will have a resulting temperature, and thus a thermal energy, greater than those of the initially ingested air, and harvests the recompressed air and its increased thermal energy. The apparatus can also humidify and warm atmospheric air before it is ingested to increase appreciably the amount of harvested thermal energy.

Abstract: Provided is an assembly for insulating substantially vertical runs of cooled surfaces that are continuously or periodically exposed to air or another gas that has a dewpoint temperature above that of the cooled surface, thereby resulting in condensation water vapor on or adjacent the cooled surface. One embodiment of the insulating assembly provides a wicking material layer adjacent the cooled surface that, in combination with transporting and evaporating structures, removes the condensate from the vicinity of the cooled surface and allows for its evaporation into the ambient gas surrounding the exterior surface of the insulating assembly. Another embodiment provides for exposing the condensate to an internal conditioned gas stream to provide for evaporation that does not necessarily utilize an exterior surface. Both embodiments remove condensate from the insulating structure and thereby tend to avoid any substantial condensate accumulation and maintain the insulating performance.
