PURPOSE:To permit simultaneous suction and exhaust in one place in a building at all times by a method wherein a positive pressure and a negative pressure, which are generated around the building, is utilized in spite of the direction of the wind around the building. CONSTITUTION:The simultaneous suction and drafting of one place may be effected by a method wherein the suction and exhaust boxes A are attached to the opposing surfaces of the building X and two sets of the suction and exhaust boxes A are connected to a suction and exhaust control terminal box B. This operation may be effected at all times by totalizing two sets of the suction and exhaust boxes A even if the wind blows from any direction. The air, forced into the room from the suction and exhaust box A, passes through an upper room B1 while the air, extracted by the negative pressure of the suction and exhaust box A, passes through a lower room B2. |
