HEAT ENERGY STORAGE Russian patent published in 2017 - IPC F24H7/04 F24J2/42 F24J2/34 

FIELD: heating.

SUBSTANCE: heat energy storage contains a reservoir that is a cavity in the ground filled with solid storing medium, which can be soil, sand, rock, incombustible solid waste, mining overburden rocks, as well as charge and discharge heat exchangers with a heat carrier connected to the heat energy source and consumer, respectively. The reservoir has heat and hydraulic insulation from the environment, the internal volume of the reservoir is divided by horizontal hydro- and heat-insulating partitions into separate sections, each of which has its own charge and discharge circuit portions with a heat carrier. The discharge and charge circuits of each hydro- and heat-insulating section are united in discharge and charge manifolds.

EFFECT: cold or heat storage is characterized by high heat output, short charging time, low heat losses, and also by easiness of fabrication and manufacturability.
