Abstract

1. A regulating device for heating or refrigeration plants comprising a heating or refrigerator means having a heating refrigerating circuit regulator, consisting of a regulating apparatus (2), at least one thermocouple (1), for example an exterior sensor, at least one energy consumption tester (4), e.g. a thermostat or valve end switch, characterized in that, after the reference temperature that is sensed by the thermocouple (1) and is set on the regulating apparatus (2) has been exceeded, the heating or, resp., refrigerator means (3) is cut off for a cutoff period adjusted in the regulating apparatus independently of the heating or, resp., refrigerating circuit regulation, and in that, after termination of the cutoff time and switching-on of the energy consumption tester (4) during said cutoff period the heating or, resp., refrigerator means (3) is released for a switched-on period that is likewise set in the regulating apparatus (2).

Description

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

Regeleinrichtungen zur Steuerung von Heizungs- und Kälteanlagen sind in den verschiedensten Ausführungen bereits bekannt. Die DE-OS 2.527.2oo 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-OS 2.527.2oo 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-AS 2.226.865 ist eine Regeleinrichtung bekannt, die mit zwei Thermogrenzwertschaltern, die unterschiedlich eingestellt sind, einen Umlaufwasserheizer und eine Umwälzpumpe schaltet.A control device is known from DE-AS 2.226.865, which switches a circulating water heater and a circulating pump with two thermal limit switches that are set differently.

Die erfindungsgemäße Regeleinrichtung hat sich nun zur Aufgabe gestellt, nach dem Überschreiten einer Bezugstemperatur, die vom Temperaturgeber gefühlt und am Regelgerät eingestellt ist, den Wärme- oder Kälteerzeuger für eine, im Regelgerät eingestellte Abschaltzeit, unabhängig von der Heiz- oder Kältekreisregelung, abzuschalten und nach Ablauf der Abschaltzeit und dem Einschalten des Energieprüfers während dieser Abschaltzeit, den Wärme- oder Kälteerzeuger für eine, ebenfalls im Regelgerät eingestellte Einschaltzeit freizugeben.The control device according to the invention has now set itself the task, after exceeding a reference temperature, which is sensed by the temperature sensor and set on the control device, the heat or cold generator for a shutdown time set in the control device, regardless of the heating or cooling circuit control, switch off and, after the switch-off time has elapsed and the energy tester is switched on 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.

Die im Regelgerät eingestellte Abschaltzeit soll sich um eine Periode verlängern,wenn sich der Energieprüfer in der vorhergehenden Abschaltzeit nicht einschaltet.The switch-off time set in the control unit should be extended by one period if the energy tester does not switch on in the previous switch-off time.

Die im Regelgerät eingestellte Einschaltzeit wird um eine Periode verlängert, wenn der Energieprüfer in der vorhergehenden Einschaltzeit nicht abschaltet.The switch-on time set in the control unit is extended by one period if the energy tester does not switch off in the previous switch-on time.

Beim Unterschreiten einer Bezugstemperatur, die vom Temperaturgeber gefühlt und im Regelgerät eingestellt ist, soll der Wärme-oder Kälteerzeuger erst in Betrieb gehen, wenn der Energieprüfer einschaltet.If the temperature falls below a reference temperature, which is sensed by the temperature transmitter and is set in the control device, the heat or cold generator should only go into operation when the energy tester 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 Blockschaltbild zeigt schematisch ein erfindungsgemäßes Regelgerät für die Steuerung eines Wärmeerzeugers (ölbefeuerter Heizkessel) in einem Wohnhaus.The block diagram shows schematically an inventive control device for the control of a heat generator (oil-fired boiler) in a house.

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, 8o 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, 4o oder 8o Min.) den Wärmeerzeuger 3 ab. Der Wärmeerzeuger 3 kann sich durch seine Betriebsregelgeräte nicht in Betrieb setzen. Fühlt der Temperaturgeber 1, nach Ablauf der eingestellten Zeit (z.B. 5, 4o oder 8o Min.), daß die eingestellte Temperatur noch überschritten ist, so wird durch den Energieprüfer 4 kontrolliert, ob der Wärmeverbraucher (z.B. Raumheizungsvorlauf) Energie benötigt. Ist dies der Fall, so wird der Wärmeerzeuger in Betrieb bzw. Betriebsbereitschaft versetzt, wobei der Energieprüfer 4 laufend kontrolliert, ob der Wärmeverbraucher noch Energie benötigt. Wirdleine 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 ist, wieder in Betrieb bzw. Betriebsbereitschaft versetzt. Dies erfolgt jedoch erst, wenn der Energieprüfer 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. In control unit 2 there is a transformer and a counting unit with time outputs (e.g. 5.4 0 , 8o 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 (in the case of refrigeration systems, the temperature falls below), the control device 2 switches off the heat generator 3 for a certain time (for example 5, 4o or 8o min.). The heat generator 3 cannot start up due to its operating control devices. If the temperature sensor 1 feels after the set time (e.g. 5, 4o or 8o min.) That the set temperature is still exceeded, the energy tester 4 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 ready for operation, the energy tester 4 continuously checking whether the heat consumer still requires energy. If a little 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 takes place when the energy tester 4 reports for the first time that the heat consumer needs energy.
