    摘要： In a cryogenic combined cycle power plant electric power drives a cryogenic refrigerator to store energy by cooling air to a liquid state for storage within tanks, followed by subsequent release of the stored energy by first pressurizing the liquid air, then regasifying the liquid air and raising the temperature of the regasified air at least in part with heat exhausted from a combustion turbine, and then expanding the heated regasified air through a hot gas expander to generate power. The expanded regasified air exhausted from the expander may be used to cool and make denser the inlet air to the combustion turbine. The combustion turbine exhaust gases may be used to drive an organic Rankine bottoming cycle. An alternative source of heat such as thermal storage, for example, may be used in place of or in addition to the combustion turbine.

    摘要： The power system comprises a working fluid circuit having a high pressure side and a low pressure side and configured to flow a working fluid therethrough. The working fluid circuit further comprises a heater configured to circulate the working fluid in heat exchange relationship with a hot fluid to vaporize the working fluid. The system further comprises serially arranged first expander and second expander fluidly coupled to the working fluid circuit and disposed between the high pressure side and the low pressure side thereof. One of the expanders drives a load and the other expander drives a pump or compressor fluidly coupled to the working fluid circuit between the low pressure side and the high pressure side thereof. A cooler is further arranged and configured to remove heat from the working fluid in the low pressure side of the working fluid circuit.

    摘要： A method and system using at least two different working fluids to be supplied to an expander to cause it to do mechanical work. The expander is started by providing a compressed gaseous working fluid at a sufficient pressure to the expander. At the same time the compressed gaseous working fluid is provided to the expander, a second working fluid that is liquid at ambient temperatures is provided to a heater to be heated. The second working fluid is heated to its boiling point and converted to pressurized gas Once the pressure is increased to a sufficient level, the second working fluid is injected into the expander to generate power, and the supply of the first working fluid may be stopped. After expansion in the expander, the working fluids are is exhausted from the expander, and the second working fluid may be condensed for separation from the first working fluid. Control circuitry controls the admission of the first and second working fluids responsive to monitoring the load on the expander.Waste heat in the exhaust from the expander can be used to heat or alternatively to dry an element in a device that can be operated as a desiccator to dry air when operated in a summer mode, or to heat air when operated in a winter mode. The air having been dried or alternatively heated is then ducted to an evaporative cooler which cools the dried air in summer mode and humidifies the heated air in winter mode.
