The heat accumulator (1) comprises a container with a wall as outer casing, a heat exchanger as a container insert, inflow and outflow connections extending out of the container and an accumulator medium in the container, partly surrounding the heat exchanger. The container has a double wall, i.e. a fixed outer casing (3) and a flexible inner casing (12). The flexible inner casing acts partly as a limitation of the accumulator medium (15). Between the outer and inner casings is a compensation chamber (27) tightly separated from the accumulator volume (14) and provided with a variable volume. The inner casing is activated by a pressure force and thereby impounds upon the contained accumulator medium, pressing it with a corresponding force onto the heat exchanger. The inner casing, through at least partial evacuation of its inner space, corresponding to a production of sub-atmospheric pressure in the accumulator volume, as activated with pressure force. |
