Abstract
A power conversion system including a first working fluid circuit and a second working fluid circuit. Heat, e.g. waste heat from a top, high-temperature thermodynamic cycle, is transferred to working fluid circulating in the first working fluid circuit and expanded in a first expander to generate useful mechanical power. A heat transfer arrangement is provided, between the first working fluid circuit and second working fluid circuit, configured for transferring low-temperature heat from the first working fluid circuit to the second working fluid circuit. In the second working fluid circuit working fluid is processed, which is expanded in at least one expander to generate useful mechanical power which is used to power a pump or compressor of the first working fluid circuit. The heat of the expanded gas is further used in a second recuperator to pre-heat the first working fluid.
