Description

Die Erfindung betrifft eine Regeleinrichtung für Heizungs-oder Kälteanlagen mit mindestens einem Wärme- oder Kälteerzeuger mit einem Heiz-oder Kältekreis regler, bestehend aus einem Regelgerät, mindestens eine, Temperaturgeber, z.B. Außenfühler, mindestens einem Energieverbrauchs prüfer, z.B. Thermostat oder Ventilendschalter.The invention relates to a control device for heating or cooling systems with at least one heat or cold generator with a heating or cooling circuit controller, consisting of a control device, at least one, temperature sensor, e.g. Outside sensor, at least one energy consumption tester, e.g. Thermostat or valve limit switch.

Regeleinrichtungen zur Steuerung von Heizungs- und Kälteanlagen sind in den verschiedensten Ausführungen bereits bekannt. Die DE-A-2.527.200 zeigt eine Regeleinrichtung für Verdampfungsbrenner durch die die Bimetall Heizwicklung des Ölreglers und die Erregerwicklung des Magnetventiles gegenüber der Zündstabanspeisung zeitverzögert an die Netzspannung anschaltbar ist.Control devices for controlling heating and cooling systems are already known in a wide variety of designs. DE-A-2.527.200 shows a control device for evaporative burners by means of which the bimetal heating winding of the oil regulator and the excitation winding of the solenoid valve can be connected to the mains voltage with a time delay compared to the ignition rod supply.

Aus der DE-B-2.226.865 ist ein Regeleinrichtung bekannt, die mit zwei Thermgrenzwertschaltern, die unterschiedlich eingestellt sind, einen Umlaufwasserheizer und eine Umwälzpumpe schaltet.From DE-B-2.226.865 a control device is known which switches a circulating water heater and a circulating pump with two thermal limit switches which are set differently.

Die erfindungsgemäße Regeleinrichtung zeichnet sich dadurch aus, dass nach dem Überschreiten einer Bezugstemperatur, die vom Temperaturgeber, z.B. Aussen fühler, gefühlt und am Regelgerät eingestellt ist, den Wärme- bzw Kälteerzeuger für eine im Regelgerät eingestellte Abschaltzeit, unabhängig von der Heizbze Kältekreisregelung, abgeschaltet wird und nach Ablauf der Abschaltzeit und dem Einschalten des Energieverbrauchs prüfers, z.B., Thermostat oder Ventilendschalter während dieser Abschaltzeit, den Wärme- bzw. Kälteerzeuger für eine ebenfalls im Regelgerät eingestellte Einschaltzeit freigegeben wird. Die im Regelgerät eingestellte Abschaltzeit soll sich um eine Periode verlängern, wenn sich der Energieverbrauchs prüfer in der vorhergehenden Abschaltzeit nicht einschaltet. Die im Regelgerät eingestellte Einschaltzeit wird um eine Periode verlängert, wenn der Energieverbrauchs prüfer in der vorhergehenden Einschaltzeit nicht abschaltet. Beim Unterschreiten einer Bezugstemperatur, die vom Temperaturgeber gefühlt und im Regelgerät eingestellt ist, soll der Wärme-wbz Kälteerzeuger erst in Betrieb gehen, wenn der Energieverbrauch prüfer einschaltet.The control device according to the invention is characterized in that after a reference temperature which is exceeded by the temperature transmitter, e.g. Outside sensor, sensed and set on the control unit, the heat or cold generator is switched off for a switch-off time set in the control unit, regardless of the heating circuit cooling circuit control, and after the switch-off time has elapsed and the energy consumption tester has been switched on, e.g. thermostat or valve limit switch during this switch-off time , the heat or cold generator is released for a switch-on time that is also set in the control unit. The switch-off time set in the control unit should be extended by one period if the energy consumption tester does not switch on in the previous switch-off time. The switch-on time set in the control unit is extended by one period if the energy consumption tester does not switch off in the previous switch-on time. If the temperature falls below a reference temperature, which is sensed by the temperature sensor and is set in the control unit, the heat and cold generator should only go into operation when the energy consumption switches on.

Nachstehend wird nun die Erfindung an Hand der Zeichnung, näher beschrieben, ohne jedoch darauf beschränkt zu sein.The invention will now be described in more detail below with the aid of the drawing, but without being restricted thereto.

Das Bockschaltbild zeigt schematisch eine erfindungsgemäße Regeleinrichtung für die Steuerung eines Wärmeerzeugers (ölbefeuerter Heizkessel) in einem Wohnhaus.The block diagram schematically shows a control device according to the invention for controlling a heat generator (oil-fired boiler) in a residential building.

Das Regelgerät 2 ist an das Stromversorgungsnetz 5 des Gebäudes angeschlossen. Im Regelgerät 2 befindet sich ein Transformator und eine Zähleinheit mit Zeitausgängen (z.B. 5,40, 80 Min). Der Temperaturgeber 1 meldet an das Regelgerät 2, ob die eingestellte Temperatur (in diesem Fall die Außenlufttemperatur), unter- oder überschritten ist. Ist die Temperatur überschritten (bei Kälteanlagen Unterschritten) so schaltet das Regelgerät 2 für eine bestimmte Zeit (z.B. 5, 40 oder 80 Min.) den Wärmeerzeuger 3 ab. Der Wärmeerzeuger 3 kann sich durch seinen Betriebsregler nicht in Betrieb setzen. Fühlt der Temperaturgeber 1, nach Ablauf der eingestellten Zeit (z.B, 5, 40 oder 80 Min.), daß die eingestellte Temperatur noch überschritten ist, so wird durch den Energieverbrauchs prüfer A kontrolliert, ob der Wärmeverbraucher (z.B. Raumheizungsvorlauf) Energie benötigt. Ist dies der Fall, so wird der Wärmeerzeuger in Betrieb bzw. Betriebsbereitschaft versetzt, wobei der Energieverbrauchs prüfer 4 laufend kontrolliert, ob der Wärmeverbraucher noch Energie benötigt. Wird keine zusätzliche Energie mehr benötigt, so wird, falls der Temperaturgeber 1 meldet, daß die eingestellte Temperatur noch überschritten ist, der Wärmeerzeuger 3 wieder für die eingestellte Zeit außer Betrieb gesetzt. Meldet der Temperaturgeber 1, daß die eingestellte Temperatur unterschritten ist, so wird die Anlage, unabhängig ob die eingestellte Zeit abgelaufen sit, wider in Betrieb bzw. Betriebsbereitschaft versetzt. Dies erfolgt jedoch erst, wenn der Energierverbrauchs prüfer 4 das erste Mal meldet, daß der Wärmeverbraucher Energie benötigt.The control device 2 is connected to the power supply network 5 of the building. Control unit 2 contains a transformer and a counting unit with time outputs (e.g. 5.40, 80 min). The temperature sensor 1 reports to the control device 2 whether the set temperature (in this case the outside air temperature) is below or exceeded. If the temperature is exceeded (for refrigeration systems, the temperature falls below), the control unit 2 switches off the heat generator 3 for a certain time (e.g. 5, 40 or 80 minutes). The heat generator 3 cannot operate due to its operating controller. If the temperature sensor 1 feels after the set time (e.g., 5, 40 or 80 minutes) that the set temperature is still exceeded, the energy consumption tester A checks whether the heat consumer (e.g. space heating flow) requires energy. If this is the case, the heat generator is put into operation or readiness for operation, the energy consumption tester 4 continuously checking whether the heat consumer still requires energy. If no additional energy is required, if the temperature sensor 1 reports that the set temperature has still been exceeded, the heat generator 3 is put out of operation again for the set time. If the temperature sensor 1 reports that the set temperature has fallen below, the system is put back into operation or ready for operation, regardless of whether the set time has expired. However, this only occurs when the energy consumption tester 4 reports for the first time that the heat consumer needs energy.
