| 摘要 |
The invention relates to a method of heating a liquid medium by means of a first thermal system (2, 3, 4, 7, 12, 13) and at least one second thermal system (5, 6, 6A, 15, 16) following said first thermal system (2, 3, 4, 7, 12, 13), which thermal systems each have at least one heat exchanger (2, 5) through which the medium flows, and which second thermal system (5, 6, 6A, 15, 16) is operated at a higher temperature level than the first thermal system (2, 3, 4, 7, 12, 13). The method is characterized in that, for the accelerated raising of the temperature of the medium in the first thermal system (2, 3, 4, 7, 12, 13), the direct feed of the medium to the same is reduced and in the extreme case prevented, and in that medium flowing through the first thermal system (2, 3, 4, 7, 12, 13) is directed in a circuit. The invention also relates to a plant for carrying out the method.
