摘要

Installation and method for the storage of thermal energy and its supply when required. The thermal energy may be solar or be derived from industry. For storage a pond is used which holds an aqueous saline solution whose concentration and temperature decreases from bottom to top and which is saturated at each level at the temperature there prevailing. Solid solute is provided at the bottom of the pond. Heat extraction is effected from solution at the bottom region and may be effected by heat exchange within the pond or by withdrawal of solution from near the bottom of the pond subjecting the withdrawn solution to heat exchange outside the pond and returning the solution and precipitated solute to the pond.
