PROBLEM TO BE SOLVED: To provide a blow-out device capable of suppressing lowering of a blown-out air volume within a target value even when a property of air current distributed from a supply opening is changed.SOLUTION: The blow-out device 50 for supplying the air toward an air-conditioned space from the supply opening 52, includes the supply opening 52, a ventilation pipe 54 for allowing the air to pass toward the supply opening 52, and a shutter 55 for making an effective opening area of the supply opening 52 variable. The effective opening area of the supply opening 52 and an effective opening area of the ventilation pipe 54 are determined to satisfy a following formula. X/{(1/h)2+(1/D)2}≤1/{(1/sh)2+(1/D)2} in which h is the effective opening area [m2]of the supply opening 52, D is the effective opening area [m2] of the ventilation pipe, s is an opening ratio of the supply opening 52, and X is a target value of an air distribution ratio under opening ratio s of the supply opening 52. |
