Description
Anwendungsgebiet der ErfindungField of application of the invention
Die Erfindung betrifft einen Antrieb für Heizungsumwfllzpumpen mittels Stirlingmotors zum Einsatz an Haizungaanlagan mit Zwangsumlauf sowie an Schwerkraftheizungsanlagen in der Anhelzphase.The invention relates to a drive for Heizungsumwfllzpumpen means of Stirling engine for use on Haizungaanlagan with forced circulation and gravity heating systems in the Anhelzphase.
Charakteristik des bekannten Standes der TechnikCharacteristic of the known state of the art
Die bekannten technischen Lösungen bezüglich des Antriebes von Heizungsumwälzpumpen basieren auf dem elektrischen Antrieb. So werden in DD 144438, DD 208396, DD 222078, DD 262263 und DE 1653721 durchweg Antriebskombinationen zwischen einem Elektromotor und einer Kreiselpumpe vorgestellt.The known technical solutions regarding the drive of heating circulation pumps are based on the electric drive. Thus DD 144438, DD 208396, DD 222078, DD 262263 and DE 1653721 consistently introduce drive combinations between an electric motor and a centrifugal pump.
Eine bekannte Lösung im Hinblick auf den Ausfall des elektrischen Stromes geht davon aus, eine elektromotorisch angetriebene Heizungsumwälzpumpe zu verwenden und zusätzlich einen elektrischen Akkumulator mit Wechselrichter und Transformator. Nachteile dieser Lösung sind, daß ständig ein vollgeladener Akkumulator installiert sein muß, der euch nur für etwa 3 Stunden die erhebliche Arttriebsleistung aufbringen kann und infolge begrenzter Lebensdauer von Zeit zu Zeit neu angeschafft werden muß. Außerdem sind ständige Wartungsarbeiten an Akkumulatoren erforderlich.A known solution with regard to the failure of the electric current is based on using an electric motor driven heating circulation pump and additionally an electric accumulator with inverter and transformer. Disadvantages of this solution are that constantly a fully charged accumulator must be installed, which can muster you only for about 3 hours, the significant type drive performance and must be purchased from time to time due to limited life. In addition, constant maintenance of batteries is required.
Ziel der ErfindungObject of the invention
Ziel der Erfindung ist es, einen vom elektrischen Stromnetz unabhängigen Antrieb für Heizungsumwälzpumpen zu schaffen, der wartungsarm und zuverlässig ist sowie keine ständigen Zusatzkosten, wie z. B. das Ersetzen überalterter Bleiakkumulatoren, verursacht.The aim of the invention is to provide a separate from the electrical power supply drive for heating circulation pumps, which is low maintenance and reliable and no permanent additional costs, such. As the replacement of obsolete lead-acid batteries caused.
Darlegung des Wesens der ErfindungExplanation of the essence of the invention
Aufgabe der Erfindung ist es, einen nichtelektrischen Antrieb für eine Heizungsumwälzpumpe zu entwickeln. Erfindungsgemäß wird das dadurch gelöst, daß ein Stlrlingmotor verwendet wird, wobei als Antriebsenergie die Ofenabgase genutzt werden. Die Heißgasseite des Stirlingmotors wird im Abzugsrohr zum Schornstein installiert. Die Kaltgasseite wird von einem Bypass des Heizungsrücklaufs gekühlt. Oer Stirlingmotor ist mechanisch in bekannter Weise mit der Heizungsumwälzpumpe verbunden.The object of the invention is to develop a non-electric drive for a heating circulation pump. According to the invention this is achieved in that a Stlrlingmotor is used, the furnace exhaust gases are used as drive energy. The hot gas side of the Stirling engine is installed in the exhaust pipe to the chimney. The cold gas side is cooled by a bypass of the heating return. Oer Stirling engine is mechanically connected in a known manner with the heating circulation pump.

Der Antrieb besteht aus dem Stirlingmotor 2, der mechanisch mit der Heizungsumwälzpumpe 7 verbunden ist. Letztere fördert in den Heizungsvnrlauf 8. Die Heißgasseite 1 ist im Bypass 10zum Abzugsrohr 3 installiert und kann über eine Klappe 9 während der Anheizphase abgeschaltet werden. Die Kaltgasseite 5 wird über einen Bypass 11 des Heizungsrücklaufes 6 zum Heizungsofen 4 gekühlt.The drive consists of the Stirling engine 2, which is mechanically connected to the heating circulation pump 7. The latter promotes in the Heizungsvnrlauf 8. The hot gas side 1 is installed in the bypass 10 to the exhaust pipe 3 and can be switched off via a flap 9 during the heating phase. The cold gas side 5 is cooled via a bypass 11 of the heating return 6 to the heating furnace 4.
