Abstract (en)

A thermal energy storage system (2) is provided. The thermal energy storage system comprises an energy storage device (4) configured to store thermal energy; a charging flow path (16) configured to provide thermal energy from a heat source (6) to the energy storage device (4) via a heat transfer medium, wherein the thermal energy storage system (2) is operable in a charging mode in which the heat transfer medium is transported along the charging flow path (16); and a discharging flow path (14) configured to provide thermal energy from the energy storage device (4) to a first heat consumer (12) via the heat transfer medium and to return the heat transfer medium at least partially to the energy storage device (4). The thermal energy storage system (2) is operable in a discharging mode in which the heat transfer medium is transported along the discharging flow path (14). The thermal energy storage system (2) further includes a second heat consumer (10) arranged in the charging flow path (16) and in the discharging flow path (14) such that the heat transfer medium passes through the second heat consumer (10) both during operation in the charging mode and during operation in the discharging mode.
