Description

Die Erfindung bezieht sich auf ein Verfahren und eine Vorrichtung zur Gleichhaltung der Temperatur eines abgeschlossenen, auf einem vorbestimmten einstellbaren Wärmegrad zu haltenden Raumes.The invention relates to a method and an apparatus to keep the temperature of a closed, on a predetermined one adjustable degree of warmth of the room to be kept.

Bei dem Verfahren der Erfindung wird zu diesem Zweck die elektrisch leitende Säule eines der zu regelnden Wärme ausgesetzten Flüssigkeitsthermometers (Quecksilber) als kapazitives Kopplungsglied zwischen einem Hochfrequenzgenerator und einem abgestimmten, die Zu- und Abschaltung von Wärme- bzw. Kältequellen besorgenden Verstärker verwendet.In the method of the invention, for this purpose, the electrical Conductive column of a liquid thermometer exposed to the heat to be controlled (Mercury) as a capacitive coupling element between a high frequency generator and a coordinated one that takes care of the connection and disconnection of heat and cold sources Amplifier used.

Die Zeichnung zeigt beispielsweise schematisch eine Vorrichtung zur Ausübung dieses Verfahrens. In dieser Zeichnung ist S der von Hand längs einer in Wärmegraden geeichten Skala verstellbare Zeiger, dessen Verschiebung längs der Thermometersäule M eine Mi2tallscheibe K bewegt. Von der Metallscheibe K, die die Belegung eines Kondensators bildet, dessen andere Belegung durch den Quecksilberspiegel der Thermometersäule dargestellt wird, führt eine Leitung nach einem Verstärker V. Der Verstärker ist auf eine bestimmte Frequenz abgestimmt, so daß sich sein Verstärkungsgrad mit der Frequenz ändert. Der durch den Quecksilberspiegel der Thermometersäule M einerseits und die Metallscheibe K andererseits gebildete Kondensator bildet ein Kopplungsglied zwischen dem Verstärker h und dem Generator E, der mit der Thermometerkugel T elektrisch verbunden ist. Mit Hilfe des Verstärkers werden in bekannter Weise Wärme- oder Kältequellen zu-oder abgeschaltet und so die Temperatur eines Raumes auf einem bestimmten, durch den Schieber S einstellbaren Wärmegrad gehalten.The drawing shows, for example, schematically a device for Exercise this procedure. In this drawing, S is the one by hand along an in Calibrated temperature scale adjustable pointer, its displacement along the thermometer column M moves a metal disk K. From the metal disk K, which is the occupancy of a Capacitor forms whose other occupancy by the mercury level of the thermometer column is shown, a line leads to an amplifier V. The amplifier is tuned to a certain frequency, so that its gain with the Frequency changes. The one by the mercury level of the thermometer column M on the one hand and the capacitor formed on the other hand, the metal disk K constitutes a coupling member between the amplifier h and the generator E, which is connected to the thermometer ball T electrically connected is. With the aid of the amplifier, heat or cold sources are generated in a known manner switched on or off and so the temperature of a room on a certain, by the slider S kept adjustable heat level.
