  • Patent number: 10358975
    Abstract: A compressed air energy storage and power generation device comprises a motor, a compressor, a pressure accumulation tank, an expander, and a generator. The motor is driven by a fluctuating input power. The compressor is mechanically connected to the motor and compresses air. The pressure accumulation tank is fluidly connected to the compressor and stores air compressed by the compressor. The expander is fluidly connected to the pressure accumulation tank and is driven by compressed air supplied from the pressure accumulation tank. The generator is mechanically connected to the expander and generates power to be supplied to a user. A cooling water flow path, whereby water flows inside a cooling water pipe for cooling air that is a working fluid, is provided inside a casing of the compressor. As a result, a compressed air energy storage and power generation device can be provided that is capable of efficiently reducing compressive axial force and of reducing power consumption.

  • Patent number: 10330008
    Abstract: A compressed-air storage and power generation method according to the present invention is provided with: a first air-compression step; a first air-storage step; a first air-supply step; a first power-generation step; a first heat-exchange step; a heat-medium storage step; a second heat-exchange step; and an air-discharge step. In the air-discharge step, when the amount of compressed air stored in a pressure-accumulation tank (12) exceeds a prescribed amount in the first air-storage step, the air compressed by a first compressor (10) is discharged outside without being stored in the pressure-accumulation tank (12). Therefore, it is possible to provide a compressed-air storage and power generation method by which fluctuating electrical power can be smoothed efficiently even after compressed air is stored up to the storage capacity of the storage space.

  • Patent number: 10215497
    Abstract: A heat exchanger including a stacking block, including: a first plate surface; a second plate surface opposite to the first plate surface; and first and second flow path plates including respective plural first and second through holes that have a standard shape. The first through holes are arranged to line up in a standard array pattern in a first direction in which a first flow path causes a first fluid to flow. The second through holes are arranged in the first direction in the same standard array pattern as the first through holes. Each of the first through holes have an area with a same overlap with the second through holes positioned on both sides of the first through holes, in the first direction. The first flow path is formed by the first and second through holes being mutually joined in the first direction, in the areas of overlap.

  • Publication number: 20180266315
    Abstract: A compressed air energy storage power generation device includes a first heat exchanger, a heat storage tank, a second heat exchanger, a heating unit, a first power distributor, and a controller. The first heat exchanger performs heat exchange between the compressed air from a compressor and the heating medium. The heat storage tank stores the heating medium heatexchanged by the first heat exchanger. The second heat exchanger performs heat exchange between the compressed air from an accumulator tank and the heating medium from the heat storage tank. The first power distributor distributes the generated power of the power generator to a power system and the heating unit. When the internal pressure of the accumulator tank reaches a predetermined pressure and the generated power is larger than the power demand, the controller supplies a part or all of the generated power to the heating unit by the first power distributor.
