Abstract

Systems for generation of liquid water are provided. In embodiments, the systems comprise a thermal desiccant unit comprising a porous hygroscopic material located within a housing including a fluid inlet and a fluid outlet, a working fluid that accumulates heat and water vapor upon flowing from fluid inlet of the housing, through the porous hygroscopic material, and to the fluid outlet of the housing, a condenser comprising a fluid inlet and a fluid outlet for condensing water vapor from the working fluid; an enthalpy exchange unit operatively coupled between the thermal desiccant unit and the condenser, wherein the enthalpy exchange unit transfers enthalpy between the working fluid output from the thermal desiccant unit and the working fluid input to the thermal desiccant unit, and, wherein the enthalpy exchange unit transfers enthalpy between the working fluid output from the condenser and the working fluid input to the condenser.
