FISCHER & STIEHL in ESSEN a. d. Ruhr. Verfahren zur Kühlung und Vorwärmung der Luft mit Hülfe der Erdwärme.FISCHER & STIEHL in ESSEN ad Ruhr. Process for cooling and preheating the air with the help of geothermal energy.
Patentirt im Deutschen Reiche vom ii. August 1877 ab.Patented in the German Empire from ii. August 1877.
Die Bodentemperatur in einer Tiefe von 2 bis 3 m unter der Oberfläche beträgt in unseren Gegenden ca. 8 bis 9 ° im Winter, und 12 bis . 130C. im Sommer; und zwar fällt das Minimum der Temperatur in den Monat März, das Maximnm in den Monat September.The soil temperature at a depth of 2 to 3 m below the surface in our areas is approx. 8 to 9 ° in winter, and 12 to. 13 0 C. in summer; the minimum of the temperature falls in the month of March, the maximum in the month of September.
Um zu untersuchen, ob diese Bodentemperatur zum Zwecke der Kühlung von Gebäuden im Sommer nutzbar zu machen sei, haben die Erfinder am 20. Juni d. J. einen Thonrohrstrang von 0,08 m lichter Weite und 20 m Länge 2,2 m tief unter die Erdoberfläche gelegt. Die eine Mündung desselben befand sich in dem im Parterre gelegenen Bureau, das andere Ende des Rohres war mit einem Schornstein in Verbindung gebracht worden.To investigate whether this floor temperature is used for the purpose of cooling buildings in the Summer is to be made usable, the inventors on June 20th d. J. a string of clay tubing 0.08 m clear width and 20 m length 2.2 m below the surface of the earth. The one The mouth of the same was in the bureau on the ground floor, the other end the pipe had been associated with a chimney.
In der im Bureau befindlichen Emgangsmündung des Rohres wurde ein Anemometer aufgestellt und vor der Mündung ein Thermometer angebrächt.An anemometer was set up in the mouth of the pipe in the office and a thermometer in front of the muzzle.
Ein zweites Thermometer war im anderen Ende des Thonrohres, wo es aus dem Erdboden wieder heraustritt, mit seiner Kugel in dasselbe eingelassen, so dafs dieses Thermometer die Temperatur der durch das Thonrohr bewegten Luft angiebt.A second thermometer was in the other end of the clay pipe where it rose from the ground comes out again, with its ball set into it, so that this thermometer the Temperature of the air moving through the clay pipe.
Infolge der saugenden Wirkung des Schornsteins geht ein constanter Luftstrom durch das Thonrohr.As a result of the suction effect of the chimney, a constant flow of air goes through it Clay pipe.
Am 22. Juni wurde der erste Versuch ge-, macht. Durch Anwärmung des Schornsteines mittels eines besonderen Feuers im Souterain wurde die Geschwindigkeit der Luft im Thonrohr auf durchschnittlich 100 m p. Minute gebracht. Während eines zehnstündigen Versuches betrug die Temperatur der ins Thonrohr einströmenden Luft im Minimum 23Y2 0 C, im Maximum 24Y2 0 C. Die Temperatur der abströmenden Luft im Rohr betrug constant 16 '/2 0C. Es wurden während der Dauer des Versuches im Ganzen 372 cbm Luft durch das Rohr geführt. The first attempt was made on June 22nd. By heating the chimney by means of a special fire in the basement, the speed of the air in the clay pipe was increased to an average of 100 m p. Minute brought. During a ten-hour experiment was the temperature of the inflowing air in the Thonrohr minimum 23Y 2 0 C, at the maximum 24Y 2 0 C. The temperature of the outflowing air in the tube was constant 16 '/ 2 0 C. It was during the duration of the experiment in A total of 372 cbm of air passed through the pipe.
Am folgenden Tage wurde ein weiterer Versuch angestellt. Da die Temperatnr der Atmosphäre aufsen nur 220C. betrag, so wurde der Bureau-Raum künstlich stark erwärmt. Während eines 14 % stündigen Versuches betrug die Temperatur an der Einströmungsmündung des Thonrohres im Minimum 221/, ° C, im Maximum 34° C. Die Temperatur der gekühlten Luft im Minimum 15,7s0 C., im Maximum 16,8° C.Another experiment was made the following day. Since the Temperatnr the atmosphere aufsen only 22 0 C. amount, the Bureau room was heavily artificially heated. During a 14% hour experiment the temperature at the Einströmungsmündung of Thonrohres in minimum 22 1 / ° C, at the maximum 34 ° C. The temperature of the cooled air in the minimum 15,7s 0 C., at a maximum 16.8 ° C .
Die Geschwindigkeit der Luft im Rohr war durchschnittlich 110 m pro Minute, und die während der Dauer des Versuches durchgeleitete Luftmenge betrug 565 cbm.The speed of the air in the pipe was an average of 110 m per minute, and the The amount of air passed through during the test was 565 cbm.
Ein 12stündiger Versuch am 25. Juni ergab bei einer mittleren Geschwindigkeit der Luft von 95 m und einer Einströmungs-Temperatur von 21 bis 21 y2 ° C, eine Temperatur der gekühlten Luft von 14,8 bis 15° C. Das durchgeleitete Luftquantum betrug 368 cbm. Dasselbe Resultat ergab ein Versuch am 26. Juni.A 12-hour test on June 25, at an average air speed of 95 m and an inflow temperature of 21 to 21 and 2 ° C., resulted in a temperature of the cooled air of 14.8 to 15 ° C. The quantity of air passed through was 368 cbm. An experiment on June 26 gave the same result.
Seitdem blieb das System bis zum 6. August ununterbrochen in Thätigkeit, jedoch ohne besondere Beheizung des Schornsteins. Die Geschwindigkeit der Luft im Rohr betrug durchschnittlich 30 m pro Minute, die Temperatur der einströmenden Luft im Minimum 17 ° C, im Maximum 23 ° C., die Temperatur der gekühlten Luft 13,5 bis 15,5° C.From then on the system remained in uninterrupted operation until August 6th, but without any particular one Chimney heating. The speed of the air in the pipe was average 30 m per minute, the temperature of the incoming air at least 17 ° C, maximum 23 ° C., the temperature of the cooled air 13.5 to 15.5 ° C.
Wie oben bemerkt, wurde die Luft aus dem Bureau entnommen, dessen Temperatur nicht mit den Schwankungen der äufseren Atmosphäre gleichen Schritt hielt. Die Temperatur der Atmosphäre betrug im angegebenen Zeitraum im Minimum 13 ° C, im Maximum 30° C.As noted above, the air was taken from the bureau, but its temperature was not kept pace with the fluctuations in the outer atmosphere. The temperature of the During the specified period, the atmosphere was a minimum of 13 ° C and a maximum of 30 ° C.
Am 7. August wurde wieder ein Versuch mit angeheiztem Schornstein gemacht.On August 7th, another experiment was made with a heated chimney.
Die Geschwindigkeit der Luft im Rohr war durchschnittlich 95 m pro Minute. Das innerhalb 10 Stunden durchgeleitete Luftquantum betrug 350 cbm. Die Temperatur der einströmenden Luft betrug im Minimum 21 '/.2 ° C, im Maximum 25 %a G., die Temperatur der gekühlten Luft 14,8° C. im Minimum und 15,9° C. im Maximum. Die Temperatur der äufseren Atmosphäre während der Dauer dieses Versuches schwankte zwischen 240 C. und 280 C.The speed of the air in the pipe was an average of 95 m per minute. The amount of air passed through within 10 hours was 350 cbm. The temperature of the incoming air was a minimum of 21 '/. 2 ° C, at a maximum 25% a G., the temperature of the cooled air 14.8 ° C. at the minimum and 15.9 ° C. at the maximum. The temperature of the outer atmosphere during the duration of this experiment fluctuated between 24 0 C. and 28 0 C.
Am Schlüsse dieses Versuches waren vom 22. Juni an 12100 cbm Luft durch das Rohr gekühlt worden.At the end of this experiment were from June 22nd with 12,100 cbm of air through the pipe been cooled.
Die Leistungsfähigkeit desselben hat sieh inzwischen noch nicht vermindert, wie aus einem Vergleich zwischen dem Versuch vom 7. August und denjenigen vom 22., 23. und 25. Juni hervorgeht. Durch die angeführten Versuche ist festgestellt, das 1 qm Rohroberfläche bej jeder äufseren Sommertemperatur pro Stunde 10 cbmThe efficiency of the same has meanwhile seen not yet diminished, as from a comparison between the August 7th experiment and those of June 22, 23 and 25. Through the cited experiments is found that the 1 square meter pipe surface at each external summer temperature per hour 10 cbm
