Abstract:
1. A system for implementing a thermodynamic cycle comprising: a condenser subsystem comprising at least one first heat exchange unit that condenses a spent working fluid stream to form a condensed working fluid stream, a working fluid pressure and flow control subsystem comprising at least a feed pump, a control valve, a bypass valve, a first temperature sensor, a second temperature sensor, a dividing valve, and a mixing valve, where a processing unit adjusts a flow rate and a pressure of a vaporization subsystem input stream from the condensed working fluid stream, a vaporization or boiling subsystem comprising at least one heat exchange unit that vaporizes the flow rate and pressure adjusted vaporization subsystem input stream to form a vaporized energy conversion subsystem input stream, and an energy conversion subsystem comprising at least one turbine that extracts a portion of thermal energy from the vaporized energy conversion subsystem input stream to form the spent working fluid stream, where the mixing valve combines the condensed working fluid stream and a pressure adjusted recirculation stream exiting the bypass valve to form a feed pump input stream, where the feed pump pumps the feed pump input stream to a higher pressure to form a pressurized stream, where the bypass valve adjusts a pressure and a flow rate of the recirculation stream to form the pressure adjusted recirculation stream, where the working fluid comprises a base component and an effective amount of a lower boiling point component, where the effective amount is sufficient to increase a power utilization efficiency of the system, without substantially changing a weight of the fluid, reducing turbine efficiency for the particular base component, and where the control valve and the bypass valve are flow control valves and are controlled by the processing unit controlled in such a way as to optimize the pressure and flow rate of the flow rate and pressure adjusted vaporization subsystem input stream optimizing a power output of the system based on a condensation temperature of the condensed working fluid stream and a final heat source temperature increasing system output between about 3% and 6% on a yearly basis.
