  • Patent number: 11851316
    Abstract: The invention relates to a tank system for cooling, storing and removing a liquid, comprising a tank for cooling the liquid and storing the liquid in a volume along a stratification axis of the volume for thermal stratification along the stratification axis, wherein the tank can be filled through a filling device having a filling inlet in an inlet region along the stratification axis and can be emptied via an outlet in an outlet region opposite the inlet region along the stratification axis. For the purpose of flexible handling, in order to prevent mixing, the supplied liquid is conveyed into a flow, which extends completely or partly in a plane perpendicular to the stratification axis, and is supplied to the liquid stored in the tank, such that the flow runs tangentially to a circular arc that extends in a plane perpendicular to the stratification axis.
