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.

Abstract: A heat transfer or storage medium containing a nitrate salt composition including at least one alkali metal nitrate and optionally alkaline earth metal nitrate; and, at least one alkali metal nitrite and optionally alkaline earth metal nitrite in an amount of 1.1 to 15.0 mol %. The molar amount of the alkali metal nitrite and optionally alkaline earth metal nitrite for a desired temperature is calculated by x nitrite = K 6 ⁡ ( T ) K 6 ⁡ ( T ) + P O ⁢ ⁢ 2 Xnitrite is the mole fraction of nitrite, K6(T) is the temperature-dependent equilibrium constant of the reaction nitrate ⇄nitrite+½ oxygen (NO3−⇄ NO2−+½ O2), pO2 is the oxygen partial pressure and T is the temperature of the nitrate salt composition.
