Abstract

The method involves using an average value of temperature, which is detected by an external temperature sensor over a time period of an even number of a whole day for switching between a heating mode, cooling mode and a standby mode. A predetermined time period is adjustable, where a good thermal insulation and a high storage capacity of a building in which a heat pump is operated is used for a long time. The times of night phase remains unconsidered or considered with less weight.

Description

Die Erfindung bezieht sich auf ein Verfahren zur Betriebsarteinstellung einer Wärmepumpe.The invention relates to a method for operating mode adjustment of a heat pump.

Wärmepumpen können zu Heiz- oder Kühlzwecken eingesetzt werden. Beim Heizbetrieb wird Energie in der Regel aus einer Umweltwärmequelle auf ein höheres Temperaturniveau angehoben, so dass Brauch- oder Heizungswasser erhitzt werden kann. Beim Kühlbetrieb wird dem zu kühlenden Raum gezielt Wärme entzogen, die an einer anderen Stelle abgeführt wird. Letztendlich kann eine Wärmepumpe sich in der Bereitschaft befinden. Dies ist ein Betriebszustand, in dem weder eine Heiz- noch eine Kühlanforderung vorliegen.Heat pumps can be used for heating or cooling purposes. In heating operation, energy is usually raised from an environmental heat source to a higher temperature level so that service or heating water can be heated. During cooling operation, the room to be cooled is specifically deprived of heat, which is dissipated at another location. Finally, a heat pump can be in standby. This is an operating condition in which there is neither a heating nor a cooling request.

Bei konventionellen Heizgeräten gemäß dem Stand der Technik wird häufig mit einem manuell zu bedienenden Schalter zwischen dem Winterbetrieb und Sommerbetrieb unterschieden. Während im Sommerbetrieb lediglich Brauchwasser erwärmt wird, wird im Winter Wärme sowohl für Brauchwasser als auch für die Raumheizung zur Verfügung gestellt. Einige Heizgeräte verfügen über einen Außentemperaturfühler, welcher automatisch die Heizung vom Sommer- auf den Winterbetrieb umschaltet. Überschreitet die Außentemperatur einen voreingestellten Wert, so wird auf Sommerbetrieb umgeschaltet. Unterschreitet die gemessene Außentemperatur wiederum einen Wert, wird auf Winterbetrieb umgeschaltet.In conventional heating devices according to the prior art, a manual switch is often used to distinguish between winter operation and summer operation. While in summer mode only service water is heated, in the winter heat is provided both for service water as well as for space heating. Some heaters have an outdoor temperature sensor, which automatically switches the heating from summer to winter operation. If the outside temperature exceeds a preset value, summer mode is switched over. If the measured outside temperature falls below a value again, the system switches over to winter operation.

Wärmepumpen können zusätzlich zum Heizbetrieb auch im Kühlbetrieb betrieben werden. Überschreitet die Außentemperatur einen bestimmten Wert, so kann eine Wärmepumpe vom Heiz- auf den Kühlbetrieb umgeschaltet werden. Hierbei ergibt sich der Nachteil, dass Außentemperaturschwankungen im Laufe eines Tages zum ständigen Umschalten führen.Heat pumps can also be operated in cooling mode in addition to the heating mode. If the outside temperature exceeds a certain value, a heat pump can be switched from heating to cooling mode. This has the disadvantage that outside temperature fluctuations in the course of a day lead to constant switching.

Die Druckschrift US 5 924 289 A zeigt ein Verfahren zur Umschaltung zwischen Heiz- und Kühlbetrieb bei einer Wärmepumpe, bei dem das Signal eines Außenfühlers zur Umschaltung dient.The publication US 5,924,289 A shows a method for switching between heating and cooling operation in a heat pump, in which the signal of an outdoor sensor is used for switching.

Aus Druckschrift JP 2004-028440 A ist bekannt, dass bei einer Klimaanlage der Mittelwert des Messsignals eines Außentemperaturfühlers der letzten 20 Tage zur Umschaltung zwischen dem Heiz- und Kühlbetrieb dient.From publication JP 2004-028440 A It is known that in an air conditioner, the mean value of the measuring signal of an outdoor temperature sensor of the last 20 days is used for switching between the heating and cooling operation.

Die Druckschrift JP 59-035745 A offenbart ein Verfahren zum Betrieb einer Klimaanlage, bei der jeden Tag zu einer bestimmten Zeit die Temperatur der Umgebung mit der Vortagstemperatur zu der gleichen Zeit verglichen wird. Ist die Temperaturdifferenz kleiner als ein Schwellgrenzwert, so wird die Anlage unverändert weiterbetrieben, andernfalls werden die Betriebsparameter angepasst. Ferner wird gleichzeitig die gemessene Temperatur mit einer Temperatur, welche der Durchschnittstemperatur im März zwischen 9 und 17 Uhr in einem durchschnittlichen Jahr entspricht, verglichen. Ist die gemessene Temperatur geringer, so schaltet die Anlage in den Winter-Modus. Ist die gemessene Temperatur hingegen größer als die Durchschnittstemperatur im Juni zwischen 9 und 17 Uhr in einem durchschnittlichen Jahr, so schaltet die Anlage in den Sommer-Modus.The publication JP 59-035745 A discloses a method of operating an air conditioner wherein each day at a certain time the temperature of the environment is compared with the pre-heating temperature at the same time. If the temperature difference is less than a threshold limit value, the system continues to operate unchanged, otherwise the operating parameters are adjusted. At the same time, the measured temperature is compared with a temperature corresponding to the average temperature in March between 9 and 17 o'clock in an average year. If the measured temperature is lower, the system switches to winter mode. On the other hand, if the measured temperature is higher than the average temperature in June between 9 am and 5 pm in an average year, the system switches to summer mode.

Aufgabe der vorliegenden Erfindung ist daher, ein Verfahren zu finden, welches eine automatische Umschaltung der Betriebsmodi bedarfsgerecht ermöglicht und hierbei die thermische Trägheit des Gesamtsystems berücksichtigt.The object of the present invention is therefore to find a method which enables an automatic changeover of the operating modes as needed and in this case takes into account the thermal inertia of the overall system.

Erfindungsgemäß wird dies gemäß den Merkmalen des unabhängigen Anspruchs 1 dadurch gelöst, dass die Betriebsarteinstellung einer Wärmepumpe in Abhängigkeit des Mittelwerts der in einem vorgegebenen Zeitraum durch einen Außentemperaturfühler erfassten Temperatur zur Umschaltung zwischen dem Heizbetrieb, dem Kühlbetrieb und der Bereitschaft genutzt wird. Um den gesamten Tagesverlauf zu berücksichtigen, ist es zweckmäßig, als vorgegebene Zeit einen gesamten Tag zu wählen. Es ist sinnvoll eine gerade Zahl ganzer Tage zu wählen, um tageszeitliche Schwankungen nicht überproportional zu berücksichtigen.According to the invention, this is achieved according to the features of independent claim 1 in that the operating mode setting of a heat pump is used as a function of the average value of the temperature detected by an external temperature sensor in a predetermined period for switching between the heating mode, the cooling mode and the standby. In order to take into account the whole course of the day, it is expedient to select a whole day as the given time. It makes sense to choose an even number of whole days in order not to disproportionately take into account daily fluctuations.

Hierbei kann gemäß Anspruch 2 die Nachtphase unberücksichtigt bleiben, da in dieser in der Regel nicht auf die Solltemperatur geregelt werden muss. Dies ist vor allem bei gut gedämmten Häusern sinnvoll, während bei schlecht gedämmten Häusern auch das Auskühlen im Winter beziehungsweise das Aufheizen im Sommer während der Nachphase berücksichtigt werden muss. In diesen Fällen kann die Regelung die Nachphasen mit geringerer Gewichtung berücksichtigen. Unter der Nachphase können generell eine bestimmte Zeitspanne oder die Zeiten der Nachtabsenkung betrachtet werden.In this case, the night phase can be disregarded according to claim 2, since in this usually does not have to be regulated to the target temperature. This is particularly useful in well-insulated houses, while in poorly insulated houses and the cooling in winter or heating in the summer during the post-phase must be considered. In these cases, the control can take into account the post-phases with a lower weighting. Under the post-phase, a certain period of time or the periods of night reduction can generally be considered.

Gemäß Anspruch 3 kann die vorgegebene Zeit einstellbar sein. Bei einer guten Wärmedämmung eines Gebäudes ist es möglich, einen lange vorgegebenen Zeitraum zu wählen, da die thermische Trägheit des Gebäudes in diesem Fall größere Schwankungen verhindert. Ist hingegen die Wärmedämmung eines Gebäudes schlecht, so muss die vorgegebene Zeit entsprechend klein gewählt werden, um ein Auskühlen oder ein Überhitzen zu vermeiden.According to claim 3, the predetermined time can be adjustable. With a good thermal insulation of a building, it is possible to choose a long predetermined period, since the thermal inertia of the building in this case prevents greater fluctuations. If, on the other hand, the thermal insulation of a building is poor, then the given time must be selected to be correspondingly small in order to avoid cooling down or overheating.

Die Erfindung wird nun anhand der Figur erläutert. Die Figur zeigt einerseits die Aufnahme der momentan gemessenen Außentemperatur Tcurrent an einem Objekt und andererseits die über die letzten 24 Std. gemittelte Außentemperaturlinie Taverage,24h, welche definitionsgemäß geringeren Schwankungen unterliegt. Es wird im Ausführungsbeispiel davon ausgegangen, dass unterhalb von 18° C (Theat) ein Heizbetrieb stattfinden soll, während oberhalb von 22° C (Tcool,on/off) der Kühlbetrieb einsetzt. Die Betriebsartenkennlinie zeigt, dass hierdurch nur wenige Umschaltungen des Betriebsmodus (standby, heating mode, cooling mode) erfolgen müssen. Zudem wird ein manuelles Umschalten des Benutzers zwischen Heizung und Kühlung überflüssig.The invention will now be explained with reference to the figure. The figure shows on the one hand the recording of the currently measured outside temperature T current on an object and on the other hand the over the last 24 hours averaged outside temperature line T average, 24h , which by definition is subject to lower fluctuations. It is assumed in the embodiment, that a heating operation should take place below 18 ° C (T heat ), while above 22 ° C (T cool, on / off ) the cooling mode starts. The operating mode characteristic shows that this means that only a few changes of the operating mode (standby, heating mode, cooling mode) must take place. In addition, a manual switching of the user between heating and cooling is unnecessary.

Wenn sich die Wärmepumpe im Heizbetrieb befindet, so bedeutet dies nicht zwangsläufig, dass sie stets betrieben werden muss, sondern auch lediglich auf eine Wärmeanforderung warten kann. Gleiches gilt für den Kühlbetrieb. Der Betriebsmodus gibt jedoch die Verschaltung der Anlage vor, so dass bei Bedarf die Wärmepumpe heizend oder kühlend für den Benutzer betrieben werden kann. Im Kühlbetrieb kann die von einem Raum abgeführte Wärme in der Regel zu Brauchwasserzwecken verwendet werden.When the heat pump is in heating mode, it does not necessarily mean that it always has to be operated but can only wait for a heat request. The same applies to the cooling operation. However, the operating mode specifies the connection of the system, so that if necessary, the heat pump can be operated heating or cooling for the user. In cooling mode, the heat dissipated from a room can usually be used for service water purposes.
