Abstract:
To provide a conditioned air duct which can reduce time required for adjustment work of an aperture of an air outlet part and reduce an error of the aperture.SOLUTION: A duct is used to distribute air, and at least one plate material of plate materials forming the duct includes a first porous part formed by multiple open pores through which air passes. The duct has: a movable plate having a second porous part which is placed overlapping with the first porous part; and a bolt which holds the movable plate so that the movable plate can rotate along an upper surface of the plate material. A ratio of an integrated aperture allowing communication between the first porous part and the second porous part is determined by a rotation angle of the movable plate.SELECTED DRAWING: Figure 8
