Abstract

The invention relates to a storage system for storing thermal energy, which has a charging circuit that contains a vaporizer, a compressor, a charging heat exchanger coupled to a heat accumulator, and an air regulator, connected directly or indirectly to one another. In order to increase the efficiency of the system, the compression and heat exchange take place in multiple stages. This means that there are numerous assemblies comprising compressors and charging heat exchangers, with downstream connecting lines. According to the invention, the charging circuit has a connection between each separator and the associated connecting lines in order to further increase the efficiency in multiple stages, wherein each separator is located between an air regulator in the subsequent stage and an air regulator belonging to the stage in which it is contained.

Abstract

The invention relates to a storage system for storing thermal energy that has a charging circuit comprising a vaporizer, a compressor, a charging heat exchanger coupled to a heat accumulator, and an air regulator, connected directly or indirectly to one another. It also requires a process steam connecting line with which external systems can be supplied with process steam. The charging circuit also contains a removal air regulator and a separator between the charging heat exchanger and the air regulator, connected directly or indirectly to one another, in which the separator is connected directly or indirectly, via a process steam heat exchanger, to the process steam connecting line.

Abstract

The invention relates to a storage system for storing thermal energy that has a charging circuit, which contains a vaporizer, a compressor, a charging heat exchanger coupled to a heat accumulator, and an air regulator, connected directly or indirectly to one another. A discharge circuit is used to recover the energy stored in the heat accumulator. The discharge circuit contains a pump, a discharge heat exchanger, a steam turbine, and a condenser, connected directly or indirectly to one another. The discharge heat exchanger is coupled to the heat accumulator in order to recover the thermal energy. To optimize the energy recovery, both the vaporizer and the condenser are coupled to the same cold reservoir.
