ACCUMULATION SYSTEM OF THERMOELECTRIC ENERGY WITH INTERMEDIATE STORAGE TANK, AND ACCUMULATION METHOD OF THERMOELECTRIC ENERGY Russian patent published in 2014 - IPC F01K3/12 

FIELD: power industry.

SUBSTANCE: accumulation system of thermoelectric energy includes a working liquid circuit intended or circulation of working liquid through heat exchanger (16), and a heat accumulating medium circuit intended for circulation of heat accumulating medium. The heat accumulating medium circulation circuit includes at least one hot storage tank (24), one intermediate storage tank (22) and one cold storage tank (20), which are connected to each other by means of heat exchanger (16). Some part of heat accumulating medium is branched and supplied to the intermediate storage tank from the hot or cold storage tank or from the intermediate storage tank to the hot or cold storage tank, thus being connected to the other part of the heat accumulating medium immediately flowing between cold and hot storage tanks.

EFFECT: high total efficiency coefficient of an accumulation system with minimum temperatures and at the same time minimisation of the amount of used heat accumulating medium and reduction of capital costs.
