High temperature thermal energy exchange system with horizontal heat exchange chamber and method for exchanging thermal energy by using the high temperature thermal energy exchange system

A method for exchanging thermal energy by using a high temperature thermal energy exchange system, comprising:

• providing at least one horizontal heat exchange chamber with chamber boundaries which surround at least one heat exchange chamber interior of the heat exchange chamber, wherein the chamber boundaries comprise at least one inlet openings for guiding in an inflow of at least one heat transfer fluid into the heat exchange chamber interior and at least one outlet openings for guiding out an outflow of the at least one heat transfer fluid out of the heat exchange chamber interior;
• wherein at least one heat storage material is arranged in the heat exchange chamber interior such that a heat exchange mass flow of the at least one heat transfer fluid through the heat exchange chamber interior causes a heat exchange between the heat storage material and the at least one heat transfer fluid, and
• wherein the high temperature thermal energy exchange system is developed such that the heat exchange mass flow of the at least one heat transfer fluid through the heat exchange chamber interior horizontal heat exchange flows differ from each other in a vertical direction,
• wherein in an operating mode of the high temperature thermal energy exchange system a heat exchange mass flow of the at least one heat transfer fluid is guided through the heat exchange chamber interior, whereby a heat exchange between the heat storage material and the at least one heat transfer fluid is caused,
• wherein the operating mode is selected from the group consisting of charging mode with a heat transfer from the at least one heat transfer fluid to the heat storage material and a discharging mode with a heat transfer from the heat storage material to the at least one heat transfer fluid,
• wherein in the charging mode a lower heat transfer flow is larger than the upper heat transfer flow, and wherein in the discharging mode an upper heat transfer flow is larger than the lower heat transfer flow.
