摘要
A thermal energy storage and recovery device includes a heat exchanger arrangement for guiding a flow of a heat transfer medium between first and second ends thereof, and a heat storage material surrounding it, forming thermal interaction region between the heat transfer medium and the heat storage material. The heat exchanger arrangement transports the heat transfer medium from the first end to the second end when the heat storage material receives thermal energy from the heat transfer medium, and transports the heat transfer medium from the second end to the first end when the heat storage material releases thermal energy to the heat transfer medium. A controller operates the device such that that when storing or recovering thermal energy to or from the heat transfer medium within the device there exists a region where the inlet and outlet temperature of the heat transfer medium of this region is kept constant.
