| 摘要 |
It is described a thermal energy storage device (100) comprising a heat exchanger arrangement (110), which is configured for guiding a flow of a heat transfer medium between a first end (112a) of the a heat exchanger arrangement (110) and a second end (114a) of the heat exchanger arrangement (110), and a heat storage material (108), which surrounds the heat exchanger arrangement (110). The heat exchanger arrangement (110) is adapted to (a) transport the heat transfer medium from the first end (112a) to the second end (114a), if the thermal energy storage device (100) is in a first operational mode, in which the heat storage material (108) is supposed to receive thermal energy from the heat transfer medium and (b) transport the heat transfer medium from the second end (114a) to the first end (112a), if the thermal energy storage device (100) is in a second operational mode, in which the heat storage material (108) is supposed to release thermal energy to the heat transfer medium. It is further described a thermal energy storing and recovering system comprising such a thermal energy storage device and a method for operating such a thermal energy storage device. |
