Abstract

A device for intermediate storage of condensation water includes a swirl body which causes an inflowing air-water mixture to rotate, and a venturi tube through which the air-water mixture leaves the device. A ring groove in which water accumulates because of the swirl is arranged downstream of the swirl body, and water accumulated in the ring groove is sucked into the venturi tube via one more suction pipes. An expansion zone has an expanded cross-section and a step shaped interior for generating increased surface adhesion. Separating metal sheets in the expansion zone brake the swirl, bind the accumulated gushing water by adhesion forces, and guide it by capillary forces to the interior surface of the expansion zone. Gushing water accumulated at the ends of the separating metal sheets is drained by one or more suction pipes, into the venturi tube.
