Description

Verfahren zur Erzielung einer niederen Dampftemperatur in Dampfheizungen. Die Reglung der Wärmeabgabe von Heizkörpern bei Unterdruckheizungen wurde bisher durch Druckänderung des Dampfes bewirkt, und es mußte der Dampfdruck möglichst niedrig gehalten werden, wenn die Wärmeabgabe in niedrigen Grenzen gehalten werden sollte. Unter Umständen, z. B. bei Heizungen mit eigenen Heizkesselanlagen, ist es aber geboten, auch ohne weitgehende Druckminderung die Wärmeabgabe der Heizkörper beträchtlich herabzusetzen.Process for achieving a low steam temperature in steam heating systems. The regulation of the heat emission of radiators with negative pressure heating was previously caused by a change in the pressure of the steam, and the steam pressure had to be as low as possible should be kept if the heat output should be kept within low limits. Under certain circumstances, e.g. B. in heating systems with their own boiler systems, but it is required, the heat dissipation of the radiators is considerable, even without extensive pressure reduction to belittle.

Nach der Erfindung geschieht eine solche Reglung der Wärmeabgabe bei Unterdruckheizungen durch Luftumwälzung. An sich ist ja das Verfahren der Luftumwälzung bei Dampfheizungen bekannt. Bei diesen bekannten Einrichtungen bezweckt aber die Luftumwälzung nur die Verdrängung der Luft und deren Mischung mit dem Dampf in den Heizkörpern oder die Gleichmäßigkeit der Wärmeabgabe auf dem ganzen Wege des Dampfluftgemisches durch dessen schnelle Bewegung. Die Kombination der beiden an sich bekannten Elemente, Luftumwälzung und Unterdruckheizung, ist aber neu, wenigstens bei solchen Heizungen, bei denen der Unterdruck durch eine besondere, unabhängig von der Heizdampfzufuhr wirkende Luftpumpe aufrechterhalten und geregelt wird. Durch diese Kombination wird einerseits gegenüber der Luftumwälzung allein eine generelle Reglung der Temperatur durch Änderung des Druckes erreicht, während gegenüber der Unterdruckheizung der Fortschritt erzielt wird, daß durch die Luftbeimischung der für eine bestimmte Temperatur erforderliche Unterdruck vermindert wird, und zwar um den Betrag des Teildruckes der Luft in dem Dämpfluftgemisch. Durch die Ausnutzung der Luftumwälzung zur Erniedrigung der Wärmeabgabe der Heizkörper bei rlen Unterdruckheizungen kommt man mit einer kleineren Vakuumpumpe aus und verringert den durch Pumparbeit bedingten Energieaufwand. Der durch die Wirksamkeit der Vakuumpumpe herbeigeführte Luftverlust in den Heizkörpern, der die Wirkung der Luftumwälzung vermindern könnte, kann in geeigneter Weise durch Lufteinlaßhähne vermieden werden.According to the invention, such a regulation of the heat emission occurs Vacuum heating through air circulation. In itself the process is air circulation known for steam heating. In these known devices, however, the aim Air circulation just displaces the air and mixes it with the steam in the Radiators or the uniformity of heat emission all the way through the steam-air mixture by its rapid movement. The combination of the two known elements, Air circulation and vacuum heating, but is new, at least with such heaters, where the negative pressure by a special, independent of the heating steam supply acting air pump is maintained and regulated. This combination makes on the one hand, compared to the air circulation, there is only a general regulation of the temperature achieved by changing the pressure, while compared to the vacuum heating of the Progress is achieved that by adding air for a certain temperature required vacuum is reduced by the amount of the partial pressure the air in the damping air mixture. By using the air circulation for humiliation the heat output of the radiators with rlen negative pressure heating comes with a smaller vacuum pump and reduces the energy expenditure caused by pumping work. The loss of air in the radiators caused by the effectiveness of the vacuum pump, which could reduce the effect of the air circulation, can be carried out in a suitable manner Air inlet taps are avoided.
