PROBLEM TO BE SOLVED: To effectually store heat in a driver constituting series passages without wasteful heat dissipation loss by passing air-conditioning air in the series air passages upon heat storage operation at night and so on through series passages of a hollow part of a series air passage void part to a heat storage air passage not passing an air-conditioned space. SOLUTION: The system defines each void part 3 of a void slab 1 with a plate part 4 extending in the length direction to construct a pair of adjacent hollow parts 5a, 5b, and these hollow parts communicate with each other at one end side of the void part to constitute series air passages of the hollow part where opposite ends of the passages are disposed on the other end side of the void part. Herein, air from an air conditioner is passed through the series air passages of the hollow part in a heat storage air passage not passing the air-conditioned space upon heat storage while upon air-conditioning the air is passed through the series air passages of the hollow part in air- conditioning air passages passing through the air-conditioning space. |
