Provided are: an intake/exhaust unit which easily controls the flow of air in an intermediate layer of a window having a double skin structure; and a double skin system using the intake/exhaust unit. The intake/exhaust unit is equipped with: a first distribution port for air to enter and exit; a second distribution port which allows air to enter and exit, and is separated from the first distribution port; a third distribution port which allows air to enter and exit, and is separated from the first distribution port and the second distribution port; a fan which blows the sucked air; a negative pressure path which is located on the side where air is sucked by the fan, and has suction holes continuous with the first, second, or third distribution port; and a positive pressure path which is located on the side where air is discharged by the fan, and has exhaust holes continuous with the first, second, or third distribution port. The intake/exhaust unit sucks air from among the first, second, or third distribution port and sends the air to one of the distribution ports other than the distribution port from which the air is sucked among the first, second, and third distribution ports. |
