PROBLEM TO BE SOLVED: To store heat efficiently in a slab as a heat storage medium. SOLUTION: In the structural heat storage system for storing heat in the structure of a building, i.e., the slab 1, by blowing heat storage supply air to the surface thereof, a duct 7 passing the heat storage supply air is installed proximately to the lower surface of the slab 1. A large number of air outlets 8 for blowing the heat storage supply air obliquely upward toward the surface of the slab 1 to generate an air flow along the surface of the slab 1 are made at a predetermined interval in the longitudinal direction at the upper part of the heat storage duct 7. When a large number of grooves 6 are formed at a constant interval in one direction by deck plates in the lower surface of the slab 1, the heat storage duct 7 is installed orthogonally to the direction of the grooves 6, and the air outlets 8 are made to blow the heat storage supply air toward each groove 6 to generate an air flow along each groove 6. The heat storage duct 7 has circular cross-section, and the air outlets 8 are made at positions slightly lower than the top thereof on the side thereof. |
