Flow-controlled heat accumulator used for storing solar energy, has heat load flow line and heat load return line that are respectively connected with valves with variable opening while traversing heat storage core by working gas flow

摘要

The heat accumulator (10) has an insulated container (12) that includes heat storage core (14) which is integrated with heating modules (44). The heat storage core is traversed by the flow of working gas through flow path (16) formed in the container wall opening. The heat load (22) is lead to a circulation line (24). The flow path is set in fluid communication with the circulation line. A flow line (26) of the heat load is connected with a first valve (30) with variable opening. A return line (28) of the heat load is connected with a second valve (32) with variable opening.
