Den Gegenstand der Erfindung bildet ein Verfahren und eine Vorrichtung zum Messen der Wärmeabgabe einer Zentralluft- oder -wasserheizungsanlage an einzelne Räume, und zwar soll mittels des Erfindungsgegenstandes die Temperaturdifferenz zwischen dem zu- und abströmenden Heizmittel festgestellt werden. Dies kann mittels bekannter Hilfsmittel, z. B. Ausdehnungskörper bewirkt werden, welche inThe subject of the invention is a method and a device for measuring the Heat dissipation from a central air or water heating system to individual rooms, namely is intended to use the subject matter of the invention to determine the temperature difference between the inflowing and outflowing Heating means are determined. This can be done using known tools, e.g. B. expansion body are effected, which in
ίο die Zu- und Ableitungen eingeschaltet werden und aus deren Anzeigen der Unterschied der Temperatur in der Zu- und Ableitung an der Stelle angezeigt wird, an welcher die Heizungsleitungen aus den Wohnräumen oder Wohnun- gen heraustreten. In der Zeichnung sind einige den Erfindungsgegenstand zeigende Vorrichtungen dargestellt.ίο the supply and discharge lines are switched on and from their displays the difference in temperature in the inlet and outlet at the Position is displayed at which the heating lines from the living rooms or apartment step out. In the drawing are some devices showing the subject matter of the invention shown.
Ein hohler Körper c (Fig. 1) wird in der Steigleitung a, ein zweiter Hohlkörper C1 in der Falleitung b angeordnet, beide Körper werden durch ein gemeinsames Rohr miteinander verbunden, vbn dem aus ein Rohr d abgezweigt wird. Die gesamte Vorrichtung' wird mit Quecksilber, ähnlich wie bei einem Thermometer, angefüllt. Am Rohr d ist ein Schauglas angebracht. In der Falleitung wird das Quecksilber weniger erwärmt als in der Steigleitung. Infolgedessen zeigt die Quecksilbersäule im Rohr d weder die Temperatur in der Steigleitung noch diejenige in der Falleitung, sondern eine mittlere Temperatur an (Fig. 1). Eine andere Ausführungsform, durch welche eine Schreib- und Anzeigevorrichtung betätigt wird, ist in Fig. 2 gezeigt. Das Rohr d, °in welches die Hohlkörper c2, C3 enden, ist oben erweitert und durch eine Membran e geschlossen. Die verschiedene Ausdehnung der in den Hohlkörpern enthaltenen Ausdehnungsflüssigkeit regelt sich nach der Differenz der Temperaturen in den beiden Leitungen. Fig. 3 zeigt eine Vorrichtung, in welcher die Ausdehnungskörper getrennt für jede Leitung angeordnet und jeder mit einer Membran versehen ist. Die Differenzbewegung dieser Membran bzw. der damit verbundenen gemeinsamen Anzeigevorrichtung ergibt dann den Temperaturunterschied. A hollow body c (Fig. 1) is arranged in the riser a, a second hollow body C 1 in the downpipe b , both bodies are connected to one another by a common pipe, from which a pipe d is branched off. The entire device is filled with mercury, similar to a thermometer. A sight glass is attached to tube d. The mercury is heated less in the downpipe than in the riser. As a result, the mercury column in pipe d shows neither the temperature in the riser nor that in the downpipe, but an average temperature (FIG. 1). Another embodiment by which a writing and display device is operated is shown in FIG. The tube d ° in which the hollow bodies c 2 , C 3 end is widened at the top and closed by a membrane e . The different expansion of the expansion fluid contained in the hollow bodies is regulated according to the difference in temperatures in the two lines. Fig. 3 shows a device in which the expansion body is arranged separately for each line and each is provided with a membrane. The differential movement of this membrane or the associated common display device then gives the temperature difference.
