PROBLEM TO BE SOLVED: To provide an intake/exhaust unit which simply controls an air flow in an interlayer on a window glass of a double skin structure and to provide a double skin system using the intake/exhaust unit.SOLUTION: An intake/exhaust unit includes: a first distribution port through which air goes in and out; a second distribution port partitioned from the first distribution port, through which air goes in and out; a third distribution port partitioned from the first distribution port and the second distribution port, through which air goes in and out; a fan which delivers sucked air; a negative pressure path of the air suction side by means of the fan, on which a suction hole joined to the first, second or third partition port is opened; and a positive pressure path of the air exhaust side by means of the fan, on which an exhaust hole joined to the first, second or third partition port is opened. Therein, air is sucked from any partition port of the first, second or third and air is delivered to any partition port besides the sucking port of the first, second or third.SELECTED DRAWING: Figure 1 |
