The low-temperature air in the low-temperature zone 18 then flows through the solid heat storage body 20 of the basic-stage heat storage box 3, the inter-stage connecting area 17, and the solid heat storage body 20 of the middle-stage heat storage box 2 in sequence, and forms high-temperature hot air again to enter the high-temperature zone 16, and repeat the above-mentioned cycle process. Finally, the heat energy stored in the solid heat storage body 20 of the basic-stage heat storage box 3 and the solid heat storage body 20 of the middle-stage heat storage box 2 is output through the heat exchange component 12 in the form of required heat medium for heat supply.

The low-temperature air in the low-temperature zone 18 flows through the solid heat storage body 20 of the basic-stage heat storage box 3, and forms high-temperature hot air again to enter the high-temperature zone 16, and the above-mentioned cycle process is repeated. Finally, the heat energy stored in the solid heat storage body 20 of the basic-stage heat storage box 3 is output through the heat exchange component 12 in the form of required heat medium for heat supply.
