Abstract
Description
Die Erfindung bezieht sich auf einen Raumtemperaturregler gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a room temperature controller according to the preamble of claim 1.
Der Regler soll derart arbeiten, daß das Verhältnis der Differenzen der Temperaturen an den Fühlern für Umgebungsluft bzw. für die Oberfläche der angegebenen Formel, wie in Anspruch 2 ausgeführt, entspricht.The controller should work in such a way that the ratio of the differences the temperatures at the sensors for ambient air or for the Surface of the formula given, as set out in claim 2, corresponds.
Bisher wurde bei Flächenheizungen lediglich die Temperatur der Heizfläche überwacht und daraus indirekt die Raumtemperatur geregelt.So far, only the temperature of the Monitoring the heating surface and indirectly regulating the room temperature.
Aus der Praxis sind jetzt auch elektronische Differenz-Temperatur regler bekannt, z.B. für Solarheizungen, deren Funktion aus der Differenz zwischen den Fühlertemperaturen abgeleitet wird, wobei ein Fühler die Temperatur des Kollektors und der andere die des Wasserspeichers ermittelt (s. Fig. 2).Electronic differential temperature controllers are now also known in practice, for example for solar heating systems, the function of which is derived from the difference between the sensor temperatures, one sensor determining the temperature of the collector and the other that of the water tank (see FIG. 2).
Der Erfindung liegt nun die Aufgabe zugrunde, einen Raumtemperatur regler für Flächenheizungen zu erstellen, der nach dem Prinzip des Zweipunktreglers mit je einem Fühler für Raum- und Flächen temperatur arbeitet, und zwar derart, daß die Abhängigkeit der Raum- und der Flächentemperatur der Funktion lt. Fig. 1 und damit zugleich der allgemein bekannten Behaglichkeitskurve ent spricht.The invention is based on the object to create a room temperature controller for surface heating, which works on the principle of the two-point controller, each with a sensor for room and surface temperature, in such a way that the dependence of the room and surface temperature of the function Fig. 1 and thus speaks the well-known comfort curve ent.
Die Lösung der der Erfindung zugrunde liegenden Aufgabe erfolgt durch die im Kennzeichen des Anspruchs 1 angegebenen Merkmale. Danach sind zur Messung des Istwertes ein erster Fühler zur Fest stellung der Raumtemperatur und ein zweiter Fühler zur Feststellung der Oberflächentemperatur in Reihe geschaltet, wobei eine gegen seitige Abhängigkeit zwischen Raumtemperatur und Oberflächen temperatur durch geeignete Wahl der Verhältnisse der Fühlerwider stände zueinander hergestellt wird. Maßgebend dabei ist, daß die gegenseitige Abhängigkeit zwischen Raumtemperatur und Ober flächentemperatur der Formel, wie in Anspruch 2 angegeben, entspricht. The object on which the invention is based is achieved by the features specified in the characterizing part of claim 1. After that, a first sensor is fixed to measure the actual value Setting the room temperature and a second sensor to determine the surface temperature connected in series, one against mutual dependence between room temperature and surfaces temperature by suitable selection of the ratios of the sensors stands are made to each other. The decisive factor is that the interdependency between room temperature and upper surface temperature of the formula as stated in claim 2, corresponds.
Besondere Vorteile bei dieser Anordnung der vorbezeichneten Art ergeben sich noch dadurch, daß durch die Reihenschaltung eines Potentiometers zu den beiden Fühlern eine Verschiebung der Kurve längs der (X)-Achse erfolgt.Particular advantages in this arrangement of the type mentioned above result from the fact that the series connection of a potentiometer to the two sensors results in a shift of the curve along the (X) axis.
Einzelheiten der Erfindung sind an einem bevorzugten Ausführungsbei spiel der Zeichnungen erläutert, wobei die Fig. 1 und 2, wie schon angedeutet, den Erkenntnissen eines vorbekannten Standes der Technik entsprechen, während die Fig. 3 und 4 jeweils ein Blockschaltbild aufzeigen, welches in der Anordnung der Komponenten den erfindungsgemäßen Raumtemperaturregler entspricht.Details of the invention are illustrated in a preferred exemplary embodiment of the drawings, wherein FIGS. 1 and 2, as already indicated, correspond to the knowledge of a prior art, while FIGS. 3 and 4 each show a block diagram, which in the arrangement of the components corresponds to the room temperature controller according to the invention.
Wie sich aus Fig. 2 weiter ergibt, wird die Differenz der Temperaturen an den Fühlern R ϑ 1 und R ϑ 2 durch einen Komparator ausgewertet, der als Zweipunktregler wirkt und die Last z.B. über ein oder über mehrere Relais schaltet.As can further be seen from FIG. 2, the difference in temperatures at sensors R ϑ 1 and R ϑ 2 is evaluated by a comparator which acts as a two-point controller and switches the load, for example, via one or more relays.
Im Gegensatz zu Fig. 2 verdeutlicht das Blockschaltbild gemäß Fig. 3 die Anordnung der Fühler R ϑ o und R ϑ u.In contrast to FIG. 2, the block diagram according to FIG. 3 illustrates the arrangement of the sensors R ϑ o and R ϑ u .
Die Gleichung aus Fig. 1 stellt sich dann ein, wenn der Fühler der Oberflächentemperatur R ϑ o den halben Widerstandswert des Raumtemperaturfühlers R ϑ u bei gleichen Temperaturen ϑ o und u aufweist. Für den Raumtemperaturfühler R ϑ u verwendet man in idealer Weise die gleichen Widerstandsfühler wie bei dem Oberflächen fühler R ϑ o. Dabei sind für den Raumtemperaturfühler zwei Fühlerele mente in Reihe geschaltet, so daß die aus Fig. 1 ersichtliche Darstellung vorteilhaft verwirklicht wird. Dies hat ferner den besonderen Vorteil, daß die Kennlinien der Widerstandselemente optimal zusammenpassen.The equation from FIG. 1 arises when the sensor of the surface temperature R ϑ o has half the resistance value of the room temperature sensor R ϑ u at the same temperatures ϑ o and u . For the room temperature sensor R θ and using the same RTD as the sensor surfaces R θ o perfectly. Here, two Fühlerele elements are connected in series for the room temperature sensor, so that the view shown in FIG. 1 is advantageously realized. This also has the particular advantage that the characteristic curves of the resistance elements fit together optimally.
Aus dem Blockschaltbild gemäß Fig. 4 ist eine einfache Möglichkeit der Anpassung der Behaglichkeitskurve nach Fig. 1 an die indi viduellen Erfordernisse des Verbrauchers ersichtlich. Das in Reihe zu den Fühlern R ϑ o und R ϑ u liegende Potentiometer R p bewirkt eine parallele Verschiebung der Behaglichkeitskurve nach Fig. 1. From the block diagram of FIG. 4 is a simple way of adjusting the comfort curve of FIG. 1 can be seen to the indi vidual requirements of the consumer. The potentiometer R p lying in series with the sensors R ϑ o and R ϑ u causes a parallel displacement of the comfort curve according to FIG. 1.
Im übrigen kann auch für die Regelung ein normaler Zweipunktregler verwendet werden, wobei der Sollwert fest eingestellt werden kann (in Fig. 3 durch einen Widerstandsteiler dargestellt).Otherwise, a normal two-point controller can also be used for the control, the setpoint being able to be set permanently (represented by a resistance divider in FIG. 3).
Durch geeignete Wahl der Widerstandswerte der Fühler können beliebige Stufen der Anpassung Δ ϑ/Δ j o an einen bestimmten Behaglichkeits bereich erzielt werden (Fig. 1).By suitable selection of the resistance values of the sensors, any level of adaptation Δ ϑ / Δ j o to a certain comfort range can be achieved ( FIG. 1).
