Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Nachstehende Erfindung soll zur Bestimmung der von einer Warmwasserheizung abgegebenen Wärmemenge dienen.The following invention is intended to determine the output of a hot water heater Serve amount of heat.

Es sind in letzter Zeit verschiedene Apparate zu diesem Zweck konstruiert worden, bei denen die abgegebene Wärmemenge sich als Produkt aus der die Heizung durchfließenden Wassermenge und der Temperaturdifferenz zwischen Zulauf und Rücklauf ergibt.Various apparatus have recently been designed for this purpose at where the amount of heat given off is the product of the amount of heat flowing through the heater The amount of water and the temperature difference between the inlet and return flow results.

ίο Ein anderer Apparat regelt den Zufluß des Wassers zu einem Wassermesser proportional der Temperaturdifferenz zwischen Zulauf und Rücklauf, so daß die abgegebene Wärmemenge der Angabe des Wassermessers direkt proportional ist. ,ίο Another device regulates the inflow of the Water to a water meter proportional to the temperature difference between inlet and Return, so that the amount of heat given off is directly proportional to the indication of the water meter is. ,

Diese Apparate benutzen für die Messung die wissenschaftliche Definition der Wärmeeinheit: Wassergewicht mal Temperaturdifferenz. These devices use the scientific definition of the unit of heat for measurement: Water weight times temperature difference.

Der hier abgebildete Apparat benutzt zur Wärrhemessung die volumverändernde Eigenschaft der Wärme.The apparatus shown here uses the volume-changing property to measure heat the warmth.

Es ist klar und durch Messungen erwiesen, daß in dem kälteren Rücklauf einer Warmwasser heizung das durchfließende Wasser ein kleineres Volumen und infolgedessen bei gleicher Lichtweite eine geringere Geschwindigkeit hat, als im Zulauf. Da das Wassergewicht in beiden Rohren, Zulauf und Rücklauf, das gleiche ist, ist die abgegebene Wärmemenge direkt proportional der Differenz der beiden Volumina im Zulauf und Rücklauf und damit auch proportional der Differenz der Geschwindigkeiten im Zulauf und Rücklauf.It is clear and proven by measurements that in the colder return there is a hot water heating the water flowing through a smaller volume and, as a result, the same Clearance has a lower speed than in the inflow. As the water weight in both pipes, inlet and return, is the same, is the amount of heat given off directly proportional to the difference between the two volumes in the inlet and outlet and thus also proportional to the difference in the velocities in the supply and return.

Der einzubauende Apparat braucht also nur diese Geschwindigkeitsdifferenz erkennen zu lassen und läßt sich dann direkt auf Wärmeeinheiten eichen.The device to be installed only needs to recognize this speed difference and can then be calibrated directly to thermal units.

Der Apparat selbst besteht aus zwei im Zulauf und Rücklauf eingesetzten Stauscheiben oder Drosselscheiben, welche je eine der Wassergeschwindigkeit entgegengerichtete Öffnung besitzen. Diese Öffnungen stehen durch Rohre mit einem Differentialmanometer oder einer anderen geeigneten Meßvorrichtung in Verbindung, dessen Meniskus oder Zeiger sich entsprechend der Verschiedenheit der Strömungsgeschwindigkeit verschiebt, was, wie eingangs geschildert, der abgegebenen Wärmemenge direkt entspricht. Die beiden Figuren zeigen den Apparat in schematischer Form und in seinem Einbau in eine Warmwasserheizung. The apparatus itself consists of two baffles installed in the inlet and the return or throttle discs, which each have an opening that is opposite to the water speed own. These openings are through pipes with a differential manometer or another suitable measuring device in connection, the meniscus or pointer according to the difference in flow velocity, what shifts, as at the beginning described, corresponds directly to the amount of heat given off. The two figures show the apparatus in schematic form and in its installation in a hot water heater.
