Abstract

To improve a heat storage system comprising a heat source, a heat storage device and a heat sink between which heat is transported by a heat transporting medium such that satisfactory storage and utilization of heat by a heat transporting medium near its critical temperature is possible, it is proposed that the heat storage device be designed as a Ruths storage device, with a bath of liquid required as heat transporting medium for the Ruths storage device being provided in a storage volume, that the storage volume contain in addition to the bath of liquid a latent heat storage material, that the storage temperature be selected so as to lie in the range of the critical temperature of the heat transporting medium and below it, and that the heat storage system be operable in such a way that during the discharging of the heat storage device via the heat sink, the bath of liquid heat transporting medium constantly surrounds the latent heat storage material essentially with thermal contact.
