The apparatus comprises an air duct with a first opening and a second opening. In the air duct, a main cooler and a first block of exchangers with at least one first sorption exchanger with an integrated heating and/or an upstream device for heating the incoming air, are positioned. The first block of exchangers is connected to the first opening. It comprises a suction unit for drawing air into the air duct and an element for collecting condensed water. The suction unit is adapted to switch between two different suction directions. The apparatus also comprises a second block of exchangers with at least one second sorption exchanger positioned in the air duct and air-interconnected to the second opening. A main cooler is positioned in the air flow path between the first block of exchangers and the second block of exchangers. The second sorption exchangers comprise integrated heating and/or are preceded upstream by at least one device for heating the entering air.

Apparatus for extracting water from air with one air duct

The apparatus comprises a first air duct with a first opening and a second opening, in the first air duct are: a cooler, a first suction device and at least part of a sorption heat exchanger having an integrated heating and/or an upstream device for preheating the incoming air. An element for collecting condensed water is also included. The apparatus also comprises a recuperative heat exchanger, which is positioned in the first air duct between the cooler and the sorption exchanger and simultaneously also between the cooler and the second opening. The recuperative heat exchanger has at least two internal conduits connected in such manner, that the first of these internal conduits air-interconnects the sorption exchanger and the cooler and that the second of these internal conduits air-interconnects the cooler and the second opening. The first and second internal conduits of the recuperative heat exchanger are in mutual thermal contact. The sorption exchanger is also air-interconnected to the first opening.
