摘要： Embodiments of the invention generally provide a heat engine system, a mass management system (MMS), and a method for regulating pressure in the heat engine system while generating electricity. In one embodiment, the MMS contains a tank fluidly coupled to a pump, a turbine, a heat exchanger, an offload terminal, and a working fluid contained in the tank at a storage pressure. The working fluid may be at a system pressure proximal an outlet of the heat exchanger, at a low-side pressure proximal a pump inlet, and at a high-side pressure proximal a pump outlet. The MMS contains a controller communicably coupled to a valve between the tank and the heat exchanger outlet, a valve between the tank and the pump inlet, a valve between the tank and the pump outlet, and a valve between the tank and the offload terminal.

摘要： A method for converting thermal energy into mechanical energy in a thermodynamic cycle includes placing a thermal energy source in thermal communication with a heat exchanger arranged in a working fluid circuit containing a working fluid (e.g., sc-CO2) and having a high pressure side and a low pressure side. The method also includes regulating an amount of working fluid within the working fluid circuit via a mass management system having a working fluid vessel, pumping the working fluid through the working fluid circuit, and expanding the working fluid to generate mechanical energy. The method further includes directing the working fluid away from the expander through the working fluid circuit, controlling a flow of the working fluid in a supercritical state from the high pressure side to the working fluid vessel, and controlling a flow of the working fluid from the working fluid vessel to the low pressure side.

摘要： Aspects of the disclosure generally provide a heat engine system with a working fluid circuit and a method for starting a turbopump disposed in the working fluid circuit. The turbopump has a main pump and may be started and ramped-up using a starter pump arranged in parallel with the main pump of the turbopump. Once the turbopump reaches a self-sustaining speed of operation, a series of valves may be manipulated to deactivate the starter pump and direct additional working fluid to a power turbine for generating electrical power.

摘要： A thermodynamic cycle is disclosed and has a working fluid circuit that converts thermal energy into mechanical energy on hot days. A pump circulates a working fluid to a heat exchanger that heats the working fluid. The heated working fluid is then expanded in a power turbine. The expanded working fluid is then cooled and condensed using one or more compressors interposing at least two intercooling components. The intercooling components cool and condense the working fluid with a cooling medium derived at ambient temperature, where the ambient temperature is above the critical temperature of the working fluid.
