Abstract
Provided herein are heat engine systems and methods for transforming energy, such as generating mechanical energy and/or electrical energy from thermal energy. The heat engine systems may have one of several different configurations of a working fluid circuit. One configuration of the heat engine system contains at least four heat exchangers and at least three recuperators sequentially disposed on a high pressure side of the working fluid circuit between a system pump and an expander. Another configuration of the heat engine system contains a low-temperature heat exchanger and a recuperator disposed upstream of a split flowpath and downstream of a recombined flowpath in the high pressure side of the working fluid circuit.
