Abstract

At least two series-connected storage cells have hot liquid supplied to or removed from a first cell and cold liquid supplied to, or removed from, a final cell. The liquid temperature decreases from the first cell to the final cell. Individual cells are connected from the warmer cell lower region to the colder cell upper region. At least one cell is closed by a cover forming a gas space between the liquid and the cover. A gas line branches off from the gas space entering into the liquid of a colder cell or into the liquid in the connection of two adjacent cells. At least one of the adjacent cells has a lower temperature than that of the cell from the gas space of which the gas line branches off.
