HEAT ENGINE SYSTEM HAVING A SELECTIVELY CONFIGURABLE WORKING FLUID CIRCUIT

摘要

Heat engine systems having selectively configurable working fluid circuits are provided. One heat engine system includes a pump that circulates a working fluid through a working fluid circuit and an expander that receives the working fluid from a high pressure side of the working fluid circuit and converts a pressure drop in the working fluid to mechanical energy. A plurality of waste heat exchangers are each selectively positioned in or isolated from the high pressure side. A plurality of recuperators are each selectively positioned in or isolated from the high pressure side and the low pressure side. A plurality of valves are actuated to enable selective control over which of the plurality of waste heat exchangers is positioned in the high pressure side, which of the plurality of recuperators is positioned in the high pressure side, and which of the plurality of recuperators is positioned in the low pressure side.
