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.

摘要： Aspects of the invention generally provide a heat engine system and a method for activating a turbopump within the heat engine system during a start-up process. The heat engine system utilizes a working fluid circulated within a working fluid circuit for capturing thermal energy. In one exemplary aspect, a start-up process for a turbopump in the heat engine system is provided such that the turbopump achieves self-sustained operation in a supercritical Rankine cycle. Bypass and check valves of a start pump and the turbopump, a drive turbine throttle valve, and other valves, lines, or pumps within the working fluid circuit are controlled during the turbopump start-up process. A process control system may utilize advanced control techniques of the control sequence to provide a successful start-up process of the turbopump without over pressurizing the working fluid circuit or damaging the turbopump via low bearing pressure.
