Description

Druckluftheizung mit Luftumwälzung. Von dem amerikanischen Erfinder Klein ist eine Druckluftheizung mit Luftumwälzung beschrieben worden, bei welcher die mit hoher Temperatur (7o bis ioo° C) zugeführte Druckluft mittels einer Düse die Raumluft in ein Mischrohr einsaugt. Aus diesem tritt die gemischte Luft in den zu heizenden Raum.Compressed air heating with air circulation. From the American inventor A compressed air heater with air circulation has been described in which the high temperature (70 to 100 ° C) supplied compressed air by means of a nozzle sucks the room air into a mixing tube. From here the mixed air enters the room to be heated.

Da Klein mit niedrigen Mischtemperaturen (von ungefähr 30' C) arbeiten will, um die Verluste durch die Decke zu vermindern, ist er gezwungen, sehr kleine Düsenquerschnitte anzuwenden, da der Wirkungsgrad der Luftstrahlapparate nur ungefähr io Prozent beträgt. Hierdurch sind aber infolge der hohen Widerstände starke Ventilatoren mit hohen Gesamtwiderständen erforderlich, welche hohen Kraftaufwand bedingen.Since Klein wants to work with low mixing temperatures (of about 30 ° C) in order to reduce the losses through the ceiling, he is forced to use very small nozzle cross-sections, since the efficiency of the air jet devices is only about 10 percent. As a result of the high resistances, however, strong fans with high overall resistances are required, which require a great deal of force.

Gegenstand dieser Erfindung ist nun die Vermeidung dieses Übelstandes, indem eine Doppeldüse verwendet wird, deren Wirkungsgrad ungefähr 40 Prozent höher ist, so daß zur Erzielung einer niedrigen Mischtemperatur durch Ansaugung der kalten Umluft keine so engen Düsenöffnungen erforderlich sind, wodurch viel Kraft erspart wird.The object of this invention is now the avoidance of this drawback, by using a double nozzle, its efficiency is approximately 40 percent higher is, so that to achieve a low mixing temperature by sucking in the cold Circulating air no such narrow nozzle openings are required, which saves a lot of power will.

Man führt zweckmäßig die Luft nur in solcher Menge zu; daß der Gesamtwärmewert der Heizluft weniger dem Gesamtwärmewert der Luft des zu beheizenden Raumes im Beharrungszustande gleich den Wärmeverlusten wird.It is expedient to supply the air only in such an amount; that the total calorific value the heating air less the total heat value of the air in the room to be heated in the steady state equal to the heat losses.

In der Zeichnung stellt L das Hauptverteilungsrohr der Heizluft vor, aus welchem sie durch Abzweige l und durch eine Doppeldüse d', d2 in das stehende Mischrohr K gedrückt wird.In the drawing, L represents the main distribution pipe for the hot air, from which it flows through branches l and through a double nozzle d ', d2 into the standing position Mixing tube K is pressed.
