Abstract: A method and arrangement for utilizing waste heat that includes a waste heat exchanger, at least two turbines, at least two recuperators, at least two cooler units, and at least two pumps and/or compressors as components, wherein all components are arranged in a single fluid cycle, where the waste heat exchanger heats up a fluid with heat from a waste heat source, the heated fluid flows through a first set of the at least one turbine, the at least one recuperator, the at least one cooler unit, and the at least one pump and/or compressor, and then flows through at least a second set the at least one turbine, the at least one recuperator, the at least one cooler unit, and the at least one pump and/or compressor with the same components arranged in series downstream of the first set.

Abstract: The present invention relates to an arrangement (1) and method for the utilization of waste heat comprising at least a waste heat exchanger (3, 3?, 3?), at least two turbines (6, 6?, 6?}, at least two recuperators (7, 7?, 7?), and at least a cooler unit (8, 9, 8?, 9?, 8?, 9?) in at least one fluid circuit. A pump and compressor (10, 10?, 10?) in one device is comprised, switchable between a pump and compressor function by a change of the rotational frequency of a rotor of the device.
