摘要:
A method and system for generating power from low- and mid-temperature heat sources using a zeotropic mixture as a working fluid. The zeotropic mixture working fluid is compressed to pressures above critical and heated to a supercritical state. The zeotropic mixture working fluid is then expanded to extract power. The zeotropic mixture working fluid is then condensed, subcooled, and collected for recirculation and recompression.
