Description
Die Erfindung bezieht sich auf eine Wärmepumpe.The invention relates to a heat pump.
Adsorptions-Wärmepumpen mit einem Sorber, der in der Adsorptionsphase als Adsorber und der Desorptionsphase als Desorber agiert, der in einem Behälter mit einem Wärmetauscher untergebracht ist, wobei dieser Wärmetauscher in der Adsorptionsphase als Verdampfer und der Desorptionsphase als Kondensator agiert, ist beispielsweise aus
Bei Adsorptions-Wärmepumpen wird ein von einer Umweltwärmequelle verdampftes Kältemittel von einem Adsorber adsorbiert, wodurch dieser sich bei der Adsorption erhitzt. Diese Wärme wird als Nutzwärme abgeführt. Anschließend muss das Kältemittel bei der Desorption wieder aus dem Adsorber, der dann als Desorber fungiert, durch Wärmezufuhr ausgetrieben werden. Das Kältemittel kondensiert an einem Kondensator, der wiederum die Wärme als Nutzwärme abgibt. Der Adsorber / Desorber strebt stets einen Gleichgewichtszustand an. Ein trockener Adsorber wird daher immer so viel Kältemittel aufnehmen, bis er sich im Gleichgewichtszustand befindet. Entscheidend für den Sorptionsprozess ist die Druckdifferenz des Partialdrucks des Kältemittels im Behälter und Sorbens. In der Adsorptionsphase sollte der Partialdruck des Kältemittels im Behälter hoch und der im Sorbens niedrig sein. Bei der Desorption sollte es möglichst umgekehrt sein. Der Partialdruck des Kältemittels im Sorbens ist ladungs- sowie temperaturabhängig. Bei konstanter Kältemittelmenge ist der Partialdruck im Behälter vom Beladungszustand des Sorbers sowie der Temperatur des Verdampfers / Kondensators abhängig. Für eine optimale Adsorption ist die Verdampfertemperatur möglichst hoch; für eine optimale Desorption die Kondensatortemperatur möglichst niedrig. In adsorption heat pumps, a refrigerant vaporized by an environmental heat source is adsorbed by an adsorber, causing it to heat upon adsorption. This heat is dissipated as useful heat. Afterwards, the refrigerant has to be expelled from the adsorber during desorption, which then acts as a desorber, by supplying heat. The refrigerant condenses on a condenser, which in turn releases the heat as useful heat. The adsorber / desorber always strives for a state of equilibrium. A dry adsorber will therefore always take in so much refrigerant until it is in equilibrium. Decisive for the sorption process is the pressure difference of the partial pressure of the refrigerant in the container and sorbent. In the adsorption phase, the partial pressure of the refrigerant should be high in the container and low in the sorbent. When desorbing it should be as reversed as possible. The partial pressure of the refrigerant in the sorbent is dependent on charge and temperature. With a constant amount of refrigerant, the partial pressure in the container depends on the loading state of the sorber and the temperature of the evaporator / condenser. For optimal adsorption, the evaporator temperature is as high as possible; for optimal desorption, the condenser temperature as low as possible.
Hierbei werden jedoch durch die Einsatzbedingungen Grenzen gegeben. In der Adsorptionsphase wird die Verdampfertemperatur durch die Umweltwärmequelle bestimmt. Bei niedriger Wärmequellentemperatur ist auch die Verdampfertemperatur gering. Bei der Desorption begünstigt eine hohe Temperatur des Sorbers (ca. 120°C) den Prozess; dies hat jedoch zur Folge, dass die Wärmequellle mit niedrigem Wirkungsgrad betrieben werden muss. Eine vergleichsweise niedrige Sorpertemperatur und somit hohen Wirkungsgrad der Wärmequelle hätte zur Folge, dass auch die Temperatur des Kondensators gering wäre und somit ein Heizkreislauf nicht damit bedient werden könnte. However, limits are given by the conditions of use. In the adsorption phase, the evaporator temperature is determined by the environmental heat source. At low heat source temperature, the evaporator temperature is low. During desorption, a high temperature of the sorber (about 120 ° C) favors the process; However, this has the consequence that the heat source must be operated with low efficiency. A comparatively low Sorpertemperatur and thus high efficiency of the heat source would have the consequence that the temperature of the capacitor would be low and thus a heating circuit could not be served with it.
Der Erfindung liegt somit die Aufgabe zugrunde, den Einsatzbereich einer Adsorptions-Wärmepumpe zu vergrößern und dabei bestimmte Parameter zu optimieren.The invention is therefore based on the object to increase the range of application of an adsorption heat pump and to optimize certain parameters.
