A method for operating a heat exchanger, in which a first operating mode is carried out in first time periods, and a second operating mode is carried out in second time periods that alternate with the first time periods; in the first operating mode a first fluid flow is formed at a first temperature, is fed into the heat exchanger in a first region at the first temperature, and is partially or completely cooled in the heat exchanger; in the first operating mode a second fluid flow is formed at a second temperature, is fed into the heat exchanger in a second region at the second temperature, and is partially or completely heated in the heat exchanger; and in the second operating mode the feeding of the first fluid flow and of the second fluid flow into the heat exchanger is partially or completely halted.

Method for operating a heat exchanger, arrangement with a heat exchanger, and system with a corresponding arrangement

The invention relates to a method for determining the state of a heat exchanger device () that comprises means for transferring heat with the aid of at least one process stream. A thermohydraulic simulation of the at least one process stream through at least one passage () in the heat exchanger device () is carried out in order to determine temperature and/or heat transfer coefficient profiles of the means for transferring heat.
