Abstract: An apparatus for extracting water from atmospheric air by means of a flowable sorbent for the sorption of the water, wherein the sorption by way of the flowable sorbent (3) is provided at least along a sorption path (2) of the sorbent (3), wherein a sorbent (4) diluted with sorbed water (17) is provided at the end of the sorption path (2), wherein a separation unit (12) for at least partially separating the sorbed water (17) from the flowable sorbent (3, 4) is provided, wherein the separation unit (12) has at least one evaporator (12) for the evaporation of the sorbed water (17), is proposed, which apparatus can be operated in an energy-efficient manner and is not imperatively reliant on the presence of solar energy. This is achieved according to the invention in that the separation unit (12) has at least one negative-pressure compressor (16) for subjecting the diluted sorbent (4) to negative pressure.

Abstract: A device for extracting water from atmospheric air (18) by means of a flowable sorbent for the sorption of the water, in particular a brine solution with a hygroscopic salt, the sorption being provided at least along a sorption path (1, 5), the flowable sorbent being arranged at least along the sorption path (1, 5) essentially on a guide element (1) for guiding the sorbent, the guide element (1) having at least two distributor elements (3), arranged at least partially vertically one above the other, for enlarging the sorption area or sorption path (5), is proposed, which achieves a better energy yield in order to implement an economical type of operation. This is achieved, according to the invention, in that a width (27), formed as a projection onto the horizontal plane, of the distributor element (3) is greater than a height (26), formed as a projection onto a vertical plane, of the distributor element (3).
