Abstract: It is proposed, in an industrial process to use the waste heat from electric converters and electric machines for the heating in a further process step. For this purpose, liquid cooling is used for the elements producing the waste heat. By this, electric or fossil-stored energy is saved, this leading in turn to a direct or indirect reduction in emitted greenhouse gasses.
