Abstract

Die Erfindung betrifft ein Verfahren zur Umwandlung und Speicherung von regenerativer Energie oder anderer überschüssiger Energie bei dem eine Flüssigkeit in einem reversiblen Kreisprozess als Speichermedium verwendet wird, das zyklisch mechanisch in ein Druckgefäß, dass mit Gas oder Dampf eines Arbeitsmittels gefüllt ist, der unter gegenüber Umgebungsdruck höherem Druck steht, gehoben und danach unter Gewinn von technischer Arbeit wieder abgelassen wird, wobei das Speichermedium in einem ersten Schritt, der Beladung, durch Zuführung von technischer Arbeit im Druck so angehoben wird, dass es in ein Druckgefäß strömt und dort befindliches dampfförmiges Arbeitsmittel aus diesem verdrängt und der Dampf des Arbeitsmittels an Flächen, die durch das Speichermedium oder ein anderes Kühlmittel indirekt gekühlt werden, kondensiert und danach im flüssigen Zustand gespeichert wird, bevor es in einem zweiten Schritt, der Entladung, durch indirekte Zuführung von Wärme des Speichermediums oder eines anderen Wärmeträgers wieder verdampft, in das Druckgefäß geleitet und das dort befindliche Speichermedium, das durch Wärmeübertragung an des Arbeitsmittel dessen Verdampfung sichert, unter Abgabe von technischer Arbeit aus diesem wieder verdrängt.

Figure imgaf001
The invention relates to a method for converting and storing regenerative energy or other excess energy in which a liquid is used in a reversible cycle as a storage medium cyclically mechanically into a pressure vessel that is filled with gas or vapor of a working medium, the under ambient pressure is higher pressure, lifted and then discharged again with the benefit of technical work, wherein the storage medium is raised in a first step, the loading, by supplying technical work in the pressure so that it flows into a pressure vessel and there befindliches vaporous working medium this displaces and the vapor of the working fluid to areas that are indirectly cooled by the storage medium or other coolant, condensed and then stored in the liquid state, before it in a second step, the discharge, by indirect supply of heat of the memory Ermediums or another heat carrier evaporated again, passed into the pressure vessel and the storage medium located there, which secures its evaporation by heat transfer to the working fluid, it displaced under the release of technical work from this again.
