    By using the biphasic flow, the recirculation wet ss oust row. be lowered compared to those systems in which ice is used single-phase heat transfer medium. This advantage is due, in particular, to the fact that the war me transition kosfficient of the levhea flow is much higher than that of the single-phase flow. A second reason is the temperature changes occurring in single-phase flow, which increase the temperature difference required for the gas and gas reservoirs. The lower heat transfer coefficient of the Einphasenströmnng must therefore be compensated on the one hand by correspondingly higher Mascorstrenn no heat exchange, on the other wet the Meschssenstrom in a single-phase system against the Abkähi- or heating ~ effects anyway set comparatively high ne r

    Fig. I shows a device 1. cub. Caching of thermal energy Nobel the device 1 in the embodiment shown as a Lätentwarmaspeicher is au. The Latettwäme memory 2 has a housing 3 with a insulated outer wall 4, wherein in the housing 3 a Wärmespeichermeäium aufgeriommen is Ais Wärmespeicherm-eäinw in the embodiment shown a Phasenwechselmateriai ("Phase Change Material" * · PCM) provided in the state of the art various such phases λ echso-materia.Vien, for example Witratsaize, are known. The latent heat storage 2 has a Guführeinrichtung S, with softer a heat transfer medium is mentioned, and a discharge device 6, with which the heat transfer medium. is dissipated. The heat transfer medium is guided inside the housing 3 by heat transfer lines 7 (see Fig. 3), which pass through the heat storage medium in the vertical direction. As will be explained further below, the heat transfer fluid is present within the heat transfer lines 7 in a first phase separation which comprises a liquid component 1 and a vapor-impermeable component The heat transfer conduits 7 are connected to heat transfer bodies 8 (see Fig. 9, 10) which are adapted to heat exchanging the heat storage medium.
    When loading the latent heat storage heat energy is stored in the heat storage medium and when unloading the latent heat spei chers 2 heat energy is accumulated on the heat storage medium, the latent heat of the phase transition of the phase change material is used Gur initiating the Einspeichervorgangs the pressure of the Eweiphasenströmung is raised, so that the saturated steam temperature exceeds the melting temperature of the salt. Thus, heat is transferred from the heat transfer medium to the Phasenwecnseimateriai. On the water / Dampi-3exte, however, a condensation process takes place. On the other hand, in order to discharge heat energy, the pressure of the water-vapor mixture is lowered so that the steam vapor temperature is lower than the melting temperature of the phase change material.
