Method of operating a plant comprising at least one absorption heat pump, and device for carrying out this method
Abstract
Bei einer Anlage mit mindestens einer Absorptions- Wärmepumpe (210) und einem Verfahren zum Betrieb einer solchen Anlage, in der ein Arbeitsmittel in einem Austreiber (214) durch Zuführen von Wärmeenergie relativ hoher Temperatur aus einem Absorptionsmittel ausgetrieben, das ausgetrieben Arbeitsmittel in einem Kondensator (218) kondensiert, das kondensierte Arbeitsmittel in einer Entspannungsvorrichtung (224) entspannt, das entspannte kondensierte Arbeitsmittel in einem Verdampfer (228) unter Zufuhr von Wärmeenergie relativ niedriger Temperatur verdampft und das verdampfte Arbeitsmittel in einem Absorber (234) wieder im Absorptionsmittel absorbiert wird, wird die zum Austreiben des Arbeitsmittels aus dem Absorptionsmittel dienende Wärmeenergie für die Wärmepumpe (210) so gespeichert, daß die aus dem Speicher entnehmbare Wärmeenergie mit einer Temperatur zur Verfügung steht, die für das Austreiben des Arbeitsmittels aus dem Absorptionsmittel ausreicht. Vorzugsweise wird als Wärmespeicher ein Sorptionsspeicher (246) verwendet, der einen Zeolith als Sorptionsmittel enthält und der einen Teil einer absatzweise arbeitenden zusätzlichen Absorptions-Wärmepumpe (212) arbeiten kann. Eine solche mit Zeolith und vorzugsweise H20 als Arbeitsstoffsystem arbeitende Wärmepumpe läßt sich auch für sich alleine mit Vorteil für die Erzeugung von Nutzwärme relativ hoher Temperatur, z.B. 80 bis 100 °C und darüber und ggf. auch zur Kälteerzeugung verwenden.
