PROBLEM TO BE SOLVED: To solve such problems that when a protrusion exists on the lower surface of a floor slab, an air flow is cut by the protrusion into pieces, its following flow rate is very reduced, and its thermal storage effect is largely decreased in an air diffusion type skeleton thermal storage air conditioning system utilizing the slab as a thermal storage medium by forming the air flow along the slab by a Coanda effect by diffusing the air from an air outlet to the lower surface of the floor slab in a ceiling. SOLUTION: An air flow control mechanism comprises a first deflector 5 provided and inclined from a projecting end of the protrusion 4 to the lower surface of the floor slab 1 of an upstream side of the air flow and a second deflector 6 disposed under the protrusion with a space. The deflector 6 has a gradient plate 8 provided and inclined upward to guide the air flow to the downstream side in a lower surface direction of the slab. |
