METHOD AND APPARATUS FOR ACQUIRING HEAT FROM MULTIPLE HEAT SOURCES.

摘要

The present invention relates to systems and methods for implementing a closed loop thermodynamic cycle utilizing a multi-component working fluid to acquire heat from two or more external heat source stream in an efficient manner utilizing countercurrent exchange. The liquid multi-component working stream is heated by a first external heat source stream at a first heat exchanger and is subsequently divided into a first substream and a second substream. The first substream is heated by the first working stream at a second external heat source stream at a second heat exchanger. The second substream is heated by the second working stream at a third heat exchanger. The first substream and the second substream are then recombined into a single working stream. The recombined working stream is heated by the second external heat source stream at a fourth heat exchanger.
