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.

Claims (18)

1. A device for the intermediate storage of condensation water from a flowing air-water mixture, said device comprising:

an inlet area;

a swirl body in the inlet area, which swirl body causes an inflowing air-water mixture to rotate;

a venturi tube, by which the air-water mixture leaves the device;

a ring groove is arranged downstream of the swirl body, in which water accumulates due to the swirl;

a plurality of suction pipes by which water accumulated in the ring groove is sucked into the venturi tube;

an expansion zone having an expanded cross-section, in which splashing water accumulates due to a flow rate reduction and due to the swirl, an interior surface of the expansion zone having a step-shaped construction for generating an increased surface adhesion force;

a plurality of separating metal sheets in the expansion zone, which metal sheets are disposed to brake the swirl and bind accumulated gushing water by adhesion forces, and guide it by capillary forces to the interior surface of the expansion zone;

wherein, gushing water accumulated at ends of the separating metal sheets is sucked via suction pipes into the venturi tube for delayed return of the splashing water into the air-water mixture.

2. The device according to claim 1 , wherein said device is connected between a condensing heat exchanger and a water separator.

3. Apparatus for regulating a flow of condensation water from an air/water mixture, said apparatus comprising:

an enclosure having an inlet area for receiving a flow of said air/water mixture, an expansion area, and an outlet tube, said expansion area having a cross-sectional area that increases in the direction from the inlet area to the outlet tube;

a swirl body situated in said inlet area, which imparts a swirl to said air/water mixture which enters said apparatus through said inlet area;

a plurality of planar elements in said expansion area, each of which is disposed along a longitudinal axis of the apparatus;

a ring groove arranged downstream of said swirl body, for accumulating water from the swirled air/water mixture; and

a first plurality of tubes connected to convey water accumulated at downstream ends of the planar elements, into the outlet tube.

4. The apparatus according to claim 3 , further comprising a second plurality of tubes connected to convey water accumulated in said ring groove to said outlet tube.

5. The apparatus according to claim 3 , wherein said interior surface has a substantially stair-stepped configuration.
