Abstract
Description
Titel: Langzeitwärmespeicher mit Aggregatzustands-Title: Long-term heat storage with state of aggregation
umwandlung in Form eines Behälters oder Beckens Beschreibung Die Erfindung betrifft einen Langzeitwärmespeicher mit Aggregatzustandsumwandlung in Form eines Behälters oder Beckens, welcher das Speichermedium insbesondere Wasser enthält, wobei in dessen Boden Wärmetauscher integriert sind, welche mit einer WElrmepumpe und vorzugsweise einer Sonnenkollektoranlage zur Wärmeentladung bzw. -ladung in Verbindung stehen. conversion in the form of a container or basin Description The The invention relates to a long-term heat storage device with state conversion in In the form of a container or basin, which holds the storage medium, in particular water contains, with heat exchangers being integrated in the bottom, which are equipped with a heat pump and preferably a solar collector system for heat discharge or charge in Connected.
Bekannt sind verschiedene Latentspeicherkonstruktionen, die im Zusammenhang mit Solaranlagen ihre Anwendung finden. Neben chemischen Latentspeichern werden auch Wasserspeicher als intermittierende Eisspeicher vor geschlagen. Ein derartig vorgeschlagener Eisspeicher weist auf dem Boden Kühlplatten auf, die mit einer Wärmepumpe in Verbindung stehen. Durch Wärmeentzug über diese Kühlplatten bildet sich eine Eisschicht, die durch kurzzeitiges Abtauen aufschwimmt und so wiederum den Wärmeentzug über die Kühiplatte ermöglicht. Eine derartige intermittierende Wärmeentnahme erfordert eine geeignete Regelungsart.Various latent storage structures are known which are related find their application with solar systems. In addition to chemical latent storage water storage as intermittent ice storage is also proposed. One of those The proposed ice store has cooling plates on the floor with a heat pump stay in contact. A heat is extracted from these cooling plates Layer of ice that floats up through brief defrosting and thus, in turn, the removal of heat made possible via the cooling plate. Such intermittent heat extraction requires a suitable type of regulation.
Dies wird erfindungsgemäß dadurch erreicht, daß der Wärmeentzug periodisch einstellbar und zur Abtauung Wärme zuführbar istD wobei der Zeitperiode zum Abtauen eine Thermostatsteuerung übergeordnet ist, die den Abtauvorgang bei Erreichen einer bestimmten Rücklauftemperatur des Heizmediums beendet und wieder auf Wärmeentzug umschaltet.According to the invention, this is achieved in that the heat is extracted periodically adjustable and heat can be supplied for defrosting D where the time period to the Defrosting is superordinated to a thermostat control, which starts the defrosting process when it is reached a certain return temperature of the heating medium ended and again on heat extraction switches.
Durch diese Kombination der Ausldsung und Beendigung des Abtauvorganges von einer Zeitintervallsteuerung mit einer Messung der Verdampfungstemperatur wird eine optimale Wärmeentnahme aus dem Speicher ermöglicht.Through this combination of the initiation and termination of the defrosting process from a time interval control with a measurement of the evaporation temperature enables optimal heat extraction from the storage tank.
Das in der Zeichnung dargestellte Regelablaufschema zeigt den Ablauf der Abtauschaltung. Für die Vereisungsdauer wird als Zeitintervall ZE gesetzt. In dieser Zeit wird ein Vierwegmagnetventil des KSlteaggregates oder die Wärmepumpe auf Vereisungsbetrieb, d.h. Wärmeentzug geschaltet. In dieser Periode wird der Latentspeicher abgekühlt. Nach Ablauf des Zeitintervalls ZE wird das Abtauintervall ZA gesetzt. Ist nun die Solerücklauftemperatur TRL unter dem Sollwert TS, wird entweder das Vierwege-Magnetventil auf Heißgasabtauung geschaltet oder die Wärmepumpe als Ganzes abgeschaltet und aus einem Wärmespeicher warme Sole der Kühlplatte zugeführt. Die Soletemperatur wird durch den Thermostat TS kontrolliert und bei einem bestimmten Wert der Abtauvorgang beendet. Sollte dieser Thermostat aus irgendeinem Grunde nicht ansprechen, wird nach Ablauf von ZA wieder auf Sühlbetrieb geschaltet.The control flow diagram shown in the drawing shows the process the defrosting. ZE is set as the time interval for the duration of icing. In During this time, a four-way solenoid valve of the cooling unit or the heat pump is activated switched to icing mode, i.e. heat extraction. During this period the latent storage cooled down. After the time interval ZE has elapsed, the defrosting interval ZA is set. If the brine return temperature TRL is below the setpoint TS, either that is Four-way solenoid valve switched to hot gas defrosting or the heat pump as a whole switched off and warm brine fed to the cooling plate from a heat accumulator. the Brine temperature is controlled by the thermostat TS and at a certain Value the defrosting process ended. For some reason this thermostat shouldn't respond, after ZA has elapsed, it is switched back to sensor mode.
