Description

Vorrichtung zur Luftkühlung Es ist bei Bewetterungsanlagen für Aufenthaltsräume bekannt, die Luft durch kaltes Wasser zu kühlen und zu entfeuchten, -um im Sommer behagliche Verhältnisse zu schaffen. Die Abkühlung der Luft erfolgt meist dadurch, daß das Kühlwasser mit der abzukühlenden Luft unmittelbar, beispielsweise in Füllkörpertürmen, in Wärmeaustausch tritt. Die Austauschvorrichtung befindet sich hierbei bisher über Gelände. Das zur Kühlung erforderliche Wasser wird durch eine Pumpvorrichtung von der Höhe des Grundwasserspiegels bis zur Wärmeaustauschvorrichtung gehoben. Die hiermit verbundene Wasserförderarbeit stellt einen Verlust dar.Device for air cooling It is used in ventilation systems for lounges known to cool and dehumidify the air with cold water, -to be used in summer to create comfortable conditions. The air is usually cooled by that the cooling water directly with the air to be cooled, for example in packed towers, enters into heat exchange. The exchange device is here so far above Terrain. The water required for cooling is supplied by a pump device from the height of the water table up to the heat exchange device. the associated water pumping work represents a loss.

Es ist auch bekannt, die Abkühlung der Luft mittelbar, beispielsweise in Röhrenkühlern, vorzunehmen, die entweder über Gelände stehen oder in einen Brunnen eingebaut sind. Gegenüber unmittelbarem Wärmeaustausch bedeutet aber der mittelbare Wärmeaustausch eine Verschlechterung der Wärmeübertragung infolge des Wärmeleitwiderstandes der Wandungen dadurch, daß der Feuchtigkeitsniederschlag aus der Luft in besonderer Weise abgeführt werden muß, während er bei unmittelbarem Austausch mit dem Kühlwasser abgeht.It is also known to cool the air indirectly, for example in tube coolers, which are either above ground or in a well are built in. Compared to direct heat exchange, however, means indirect Heat exchange a deterioration in the heat transfer due to the thermal resistance the walls in that the moisture precipitation from the air in particular Way must be discharged, while he is in direct exchange with the cooling water going off.

Die Erfindung will den mit der Wasserförderung verbundenen Arbeitsaufwand verringern, ohne den Nachteil mittelbaren Wärmeaustausches in Kauf nehmen zu müssen und besteht darin, daß in den Brunnenschacht ein Lufteinführungsstutzen eingesetzt und der Zwischenraum zwischen Schachtwandung und Lufteinführungsstutzen mit Füllkörpern ausgefüllt ist. Die Erfindung ist in der Zeichnung in einem Ausführungsbeispiel dargestellt. Die abzukühlende Luft tritt bei a durch eine Leitung b, die zweckmäßig aus schlecht leitendem Baustoff, z. B. einem Tonrohre, besteht. Am unteren Ende c der Leitung b kehrt die Luft um und tritt durch eine die Leitung b umgebende unten geschlossene Leitung d zurück. e stellt den Stand des Grundwasserspiegels dar. Die aus b und d bestehende Vorrichtung ist bis unterhalb des Grundwasserspiegels geführt. f stellt eine Fördervorrichtung dar, durch die die Luft zur Verwendungsstelle gedrückt wird. Nach dem Austritt aus b erfährt die Luft eine Abkühlung. Die Leitung d wird in den Wandungen wasserdurchlässig gehalten und der Zwischenraum zwischen b und d mit Füllkörpern, z. B. Kies, ausgefüllt, um das durchsickernde Wasser über eine vergrößerte Oberfläche auszubreiten und dadurch die Kühlwirkung zu steigern. Die Pumpvorrichtung h hebt das Wasser bis oberhalb des Grundwasserspiegls e und nicht bis zu der größeren Höhe der Luftfördervorrichtung f. Die Ausmündung i der Druckleitung wird zweckmäßig stromabwärts gerichtet, so daß stets nur nachströmendes kaltes Grundwasser in Wärmeaustausch tritt.The invention aims to reduce the amount of work associated with pumping water without having to accept the disadvantage of indirect heat exchange and consists in that an air inlet nozzle is inserted into the well shaft and the space between the shaft wall and air inlet nozzle is filled with fillers. The invention is shown in the drawing in an exemplary embodiment. The air to be cooled occurs at a through a line b, which is expediently made of poorly conductive building material, e.g. B. a clay pipes. At the lower end c of the line b, the air reverses and emerges through a line d which is closed at the bottom and which surrounds the line b. e represents the level of the groundwater level. The device consisting of b and d is guided to below the groundwater level. f represents a conveying device through which the air is pushed to the point of use. After exiting from b, the air is cooled down. The line d is kept permeable to water in the walls and the space between b and d is filled with fillers, e.g. B. gravel, filled in to spread the seeping water over an enlarged surface and thereby increase the cooling effect. The pumping device h lifts the water above the groundwater level e and not up to the greater height of the air delivery device f. The outlet i of the pressure line is expediently directed downstream so that only the inflowing cold groundwater always exchanges heat.
