Abstract

Die Erfindung betrifft ein Verfahren zum Erwärmen eines flüssigen Mediums mittels einem ersten (2,3,4,7,12,13) und mindestens einem diesem nachfolgenden zweiten thermischen System (5,6,6A,15,16), welche thermischen Systeme jeweils mindestens einen vom Medium durchströmten Wärmetauscher (2,5) aufweisen und welches zweite thermische System (5,6,6A, 15,16) auf einem höheren Temperaturniveau als das erste (2,3,4,7,12,13) betrieben wird. Das Verfahren ist dadurch gekennzeichnet, dass zur beschleunigten Anhebung der Temperatur des Mediums im ersten thermischen System (2,3,4,7,12,13) die direkte Zufuhr des Mediums zu demselben vermindert und im Extremfall unterbunden wird, und dass das erste thermische System (2,3,4,7,12,13) durchströmende Medium kreislaufgeführt wird. Die Erfindung betrifft auch eine Anlage zur Durchführung des Verfahrens.

The invention relates to a method for heating a liquid medium by means of a first (2,3,4,7,12,13) and at least one subsequent second thermal system (5,6,6A, 15,16), which thermal systems respectively Have at least one medium flowed through the heat exchanger (2.5) and which second thermal system (5,6,6A, 15,16) at a higher temperature level than the first (2,3,4,7,12,13) is operated , The method is characterized in that for the accelerated increase of the temperature of the medium in the first thermal system (2,3,4,7,12,13), the direct supply of the medium to the same is reduced and prevented in the extreme case, and that the first thermal System (2,3,4,7,12,13) flowing medium is circulated. The invention also relates to a system for carrying out the method.
