The externally-heated turbine engine produces compressed air that is heated by the reactor heat exchanger. The heat recuperating system includes a heat exchanger thermally connected to the externally-heated turbine engine to transfer heat to the compressed air to supplement the reactor heat exchanger.

摘要： Thermal battery systems for management (e.g., load management) of electrical power sources, and related methods, are generally described. Thermal battery systems in certain embodiments have an electric heater, a thermal storage system, a heat exchange system and an electricity generator. The electric heater is configured to be connected in electrical communication with an electric power source, such as an electric power grid and to heat the thermal storage system. The electric heater may be a separate unit from the thermal storage system and heat the thermal storage system indirectly by heating a first fluid that is circulated through the thermal storage system during charging, or the electric heater may be integrated directly into the thermal storage system to heat it directly. The thermal storage system is configured to store thermal energy from the electric heater during a charging mode of the thermal storage system, and to heat the first fluid, which is then supplied to a heat exchange system during a discharging mode of the thermal storage system. The heat exchange system comprises at least one heat exchanger, and in some cases, at least a first and a second heat exchanger connected in series. The heat exchange system is positioned downstream from the thermal storage system and is configured to transfer heat from the heated first fluid to a second compressed fluid. The electricity generator may comprise at least one gas turbine and compressor. The compressor is configured to supply the second compressed fluid to the heat exchange system. The turbine is positioned with an inlet in fluid communication with and downstream from the heat exchange system so that the heated compressed second fluid is discharged from an outlet of the heat exchange system into the inlet of the turbine so that the turbine is able to generate electrical power therefrom. The power generated can be returned to the electrical power source, e.g., an electrical power grid.

摘要： A system includes at least one storage tank configured to store at least one of first compressed air or liquid air. The system also includes a power supply system comprising a turbine, a generator, and a flywheel. The power supply system is configured to receive second compressed air from the at least one storage tank, wherein the second compressed air comprises either the first compressed air or the liquid air which has been heated into a gaseous state; spin the turbine and the flywheel using the second compressed air, wherein the spinning of the turbine generates electrical energy at the generator; provide the electrical energy to a data center for powering electronic devices of the data center; and provide at least a portion of the second compressed air exhausted by the turbine to the data center for cooling the electronic devices of the data center.

摘要： In a main flow passage, a first heat exchanger, a first heat storage unit, a second heat exchanger, and a second heat storage unit are connected by a heating medium flow passage. The main flow passage allows a heating medium to be circulated. A sub flow passage includes a shortened flow passage which is a part of the heating medium flow passage and branches from the heating medium flow passage between the second heat exchanger and the second heat storage unit and extends to the first heat storage unit. The sub flow passage allows circulation of the heating medium between the first heat storage unit and the second heat exchanger. A first heating means in a middle of the shortened flow passage, the first heating means heating a passing heat medium, and a switching means conducting switching between the main flow passage and the sub flow passage are provided.

摘要： A thermal storage subsystem may include at least a first storage reservoir disposed at least partially under ground configured to contain a thermal storage liquid at a storage pressure that is greater than atmospheric pressure. A liquid passage may have an inlet connectable to a thermal storage liquid source and configured to convey the thermal storage liquid to the liquid reservoir. A first heat exchanger may be provided in the liquid inlet passage and may be in fluid communication between the first compression stage and the accumulator, whereby thermal energy can be transferred from a compressed gas stream exiting a gas compressor/expander subsystem to the thermal storage liquid.

摘要： A heat pump includes an electric motor driven by input electric power, a first compressor mechanically connected to the electric motor and compresses air, a first heat exchanger performing heat exchange between compressed air produced by the first compressor and water, and a first hot water outlet through which the water heated by heat exchange in the first heat exchanger is taken out. Thus, in the air refrigerant heat pump, it is possible to use only air and water to supply heating by applying part of compressed air energy storage technology to the heat pump.
