Ball circulating heat accumulator for storing heat from renewable energy sources, has balls that are used in heat exchanger, such that geometrically defined guidance of balls to closed pipes or open channels system is performed

摘要

The ball circulating heat accumulator has non-pressurized or pressurized heat exchanger (1) that is operated according to the counterflow principle. The balls are used as a solid storage medium in heat exchanger, such that geometrically defined guidance of balls to closed pipes and/or open channels system, and separation of the balls within heat exchangers connected to storage tank (2) and the reservoir (5).
