VENTILATING SYSTEM USING HOLLOW STRUCTURE OF STRUCTURE SKELETON

摘要

PURPOSE: To provide a ventilating system in which the laying distance of duct can be shortened. ;CONSTITUTION: An indoor ventilation port 40 for ventilation which can ventilate a hollow part and indoor communicates with the hollow structure part A of the support 10 or the beam 11 of the structure skeleton of a building. Further, a ventilating fan 20 is provided, in place, at the part A, and an outdoor ventilation port 30 for ventilation which can ventilate the hollow part and outdoor is communicated. The communication passage in which the hollow parts communicated with each other may be shut OFF by a communication passage shut-off member to form a communication system in which the hollow parts do not communicate with each other. As the member, an openable ventilation valve may be used. The interior of the part A may be partitioned by a partition member, and at least two or more hollow parts which do not communicate with each other may be formed.;COPYRIGHT: (C)1996,JPO
