PATENTAMT.PATENT OFFICE.
Die vorliegende Neuerung betrifft ein Verfahren nebst Vorrichtung zur Kühlung von Gasen oder Dämpfen. Dieselbe eignet sich auch zur Kühlung von Luft und kann daher auch bei Lüftungsanlagen für Gebäude Anwendung finden.The present innovation relates to a method and device for cooling Gases or vapors. The same is also suitable for cooling air and can therefore can also be used in ventilation systems for buildings.
Die bei der Vorrichtung zur Anwendung kommende Kühlwirkung beruht auf der Temperaturerniedrigung, welche bei der Verdunstung einer Flüssigkeit eintritt und die um so bedeutender ist, je mehr die Verdunstung durch Luftbewegung unterstützt wird.The cooling effect used in the device is based on the Temperature decrease, which occurs when a liquid evaporates and which The more the evaporation is supported by air movement, the more important it is.
Um die Temperatur der Ventilationsluft für Gebäude zu erniedrigen, sind bisher Einrichtungen in Gebrauch gewesen, welche darauf beruhen, däß die zu kühlende Luft durch Wasserschleier oder Regenbrausen hindurchgeführt wird, wobei jedoch der Nachteil eintritt, daß sich die Ventilationsluft stark mit Wasserdampf sättigt.In order to lower the temperature of the ventilation air for buildings, facilities are hitherto have been in use, which are based on the air to be cooled is passed through water veils or rain showers, but with the disadvantage occurs that the ventilation air is strongly saturated with water vapor.
In vereinzelten Fällen hat man die Ventilationsluft auch gegen Röhren geleitet, welche von Wasser (Brunnenwasser von möglichst niedriger Temperatur) durchflossen werden. Abgesehen von dem geringen Effekt solcher Anlagen stellt sich der Betrieb derselben wegen des großen Wasserverbrauches sehr kostspielig.In isolated cases the ventilation air has also been directed against pipes, which water (well water at the lowest possible temperature) flow through. Apart from the small effect of such systems, the operation of the same arises very expensive because of the large amount of water used.
Bei der in Rede stehenden Neuerung "wird die durch Verdunstung eintretende Temperaturerniedrigung in der Weise benutzt, daß ein Teil der dem Apparate zugeführten Luftmenge die Verdunstung beschleunigt und die Kühlung der anderen Luftmenge bewirkt.In the case of the innovation in question, "the decrease in temperature caused by evaporation used in such a way that part of the amount of air supplied to the apparatus accelerates evaporation and the Causes cooling of the other amount of air.
Der Apparat zeigt hierbei im wesentlichen folgende in der beiliegenden Zeichnung schematisch dargestellte Einrichtung.The apparatus shows the following schematically in the accompanying drawing facility shown.
Die durch einen Ventilator V oder in geeigneten Fällen durch Temperaturdifferenz oder Windbewegung in den Schacht A eingeführte Luft strömt zum Teil in der Richtung c- d durch ein System JR1 von Hohlkörpern aus dünnen Metallwänden oder keramischem Material und gelangt so in die Luftleitung L, welche die gekühlte Ventilationsluft den einzelnen Räumen zuführt. Der übrige Teil der in den Apparat eingeführten Luft umspült die äußeren Flächen des Systems R1 und beschleunigt die Verdunstung der durch einen Berieselungsapparat m über die äußeren Flächen des Systems R1 fein verteilten Wassermengen oder einer anderen geeigneten Flüssigkeit. The air introduced into the shaft A by a fan V or, in suitable cases, by temperature difference or wind movement flows partly in the direction c-d through a system JR 1 of hollow bodies made of thin metal walls or ceramic material and thus enters the air line L, which the cooled ventilation air is supplied to the individual rooms. The remaining part of the air introduced into the apparatus washes around the outer surfaces of the system R 1 and accelerates the evaporation of the amounts of water or another suitable liquid which have been finely distributed by a sprinkler m over the outer surfaces of the system R 1.
Da hierbei die das System JR1 umspülende Luft in der direkten Berührung mit der verdunstenden Flüssigkeit gleichfalls eine Temperaturerniedrigung erfährt, wird dieselbe zur Vorkühlung der durch den Schacht A einströmenden frischen Luft benutzt und zu dem Zwecke -durch ein zweites System R2 von Hohlkörpern geleitet, welches von dem frisch eintretenden Luftstrom umspült wird, so daß ein möglichst vollständiger Temperaturausgleich zwischen der bei A eintretenden und der bei B ausströmenden Luft eintritt und die durch Verdunstung der Berieselungsflüssigkeit entstandene Temperaturerniedrigung möglichst vollständig auf die bei L abströmende Ventilationsluft übergeht.Since the air surrounding the system JR 1 also experiences a temperature decrease in direct contact with the evaporating liquid, it is used to pre-cool the fresh air flowing in through the shaft A and for the purpose - passed through a second system R 2 of hollow bodies, which is washed around by the freshly entering air stream, so that a temperature equalization as complete as possible between the air entering at A and the air flowing out at B occurs and the temperature decrease caused by evaporation of the sprinkling liquid is transferred as completely as possible to the ventilation air flowing out at L.
Erfolgt die Luftbewegung durch maschinellen Antrieb, so ist es vorteilhaft, den unteren Teil als Sammelschale. S für das Berieselungswasser auszubilden und letzteres wieder in den Berieselungsapparat zu fördern, da das Berieselungswasser bei der durch die Luftbewegung hervorgerufenen lebhaften Verdunstung gleichfalls stark gekühlt wird und infolgedessen bei einem derartigen KreislaufIf the air is moved by a machine, it is advantageous to use the lower part as a collecting bowl. S for the sprinkling water and to convey the latter back into the sprinkling apparatus, since the sprinkling water is also strongly cooled in the lively evaporation caused by the air movement and consequently in such a cycle
ίο der Berieselungsflüssigkeit die Wirkung des Apparates sich bis zu einem gewissen Beharrungszustande steigert.ίο the sprinkling liquid reduces the effect of the Apparatus increases to a certain state of equilibrium.
Wird bei der Kühlung der Ventilationsluft gleichzeitig eine Befeuchtung derselben gefordert, so kann durch eine mittels einer Regulierklappe K verschließbaren Öffnung ein .Teil der durch das Berieselungswasser gesättigten Luft der frischen angesaugten Luft nach Bedarf beigemischt werden.At the same time the same required in cooling of the ventilation air humidification, an .Teil the saturated by the sprinkler water, the fresh air sucked air are mixed as required by a closable by means of a regulating damper K opening.
