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.

摘要： A refrigeration cycle is operated in conjunction with various thermodynamic cycle working fluid circuits to cool a target fluid that may be used in a separate system or duty. In one embodiment, the refrigeration cycle includes an ejector that extracts a motive fluid from the working fluid cycles in order to entrain a suction fluid that is also extracted from the working fluid circuits. Expanding the suction fluid reduces the pressure and temperature of the suction fluid for cooling the target fluid in an evaporator, which evaporates the suction fluid before being entrained into the ejector by the motive fluid. A mixed fluid is discharged from the ejector and injected into the working fluid circuits upstream from a condenser that cools the mixed fluid and the working fluid circulating throughout the working fluid circuits.
