| 摘要 |
The invention relates to a device for temporarily storing gas and heat, comprising at least one pressure container (10), multiple compressors (3, 8, 9), by means of which a gas (1) can be compressed, and multiple compression stages, which are connected in series and each of which comprises one of the compressors (3, 8, 9) and a gas flow path (11, 12, 13) connected downstream of the compressor, wherein the final compression stage of the series is connected upstream of the pressure container (10) in which the gas (1) compressed by means of the compressors (3, 8, 9) can be stored. The device also comprises a heat accumulator arrangement (7) which comprises multiple heat accumulators (4, 5, 6) and by means of which compression heat generated by the compression of the gas (1) can be stored. The heat accumulator arrangement (7) is connected in the gas flow path (11, 12, 13) of each compression stage, a heat accumulator sequence is assigned to the heat accumulators (4, 5, 6), and the gas flow path (11, 12, 13) of each compression stage passes through the heat accumulators (4, 5, 6) successively in the heat accumulator sequence. |
