VENTILATION ROUTE SWITCHING DEVICE, HEAT EXCHANGE VENTILATION SYSTEM OF BUILDING AND HEAT EXCHANGE VENTILATION METHOD OF BUILDING

摘要

PROBLEM TO BE SOLVED: To provide a ventilation route switching device capable of switching a ventilation route by a simple configuration.;SOLUTION: In the ventilation route switching device 1, inside of a square cylindrical casing 2 having closed both ends is partitioned into two sections 2a, 2b by a central partition wall 3, and the respective sections 2a, 2b are partitioned into two sections by a vertical partition wall 4 and a horizontal partition wall 5, respectively. Ducts D1-D4 are connected to the first to fourth sections partitioned by the three partition walls. The central partition wall 3 is partitioned into four regions by connection lines L1, L2 of the vertical partition wall 4 and horizontal partition wall 5 intersecting with each other to form a cross shape, and one opening is formed on each of the regions E1-E4. By positioning slide plates B1, B2 in a first closing position or a second closing position to close the openings H1, H4 or the openings H2, H3 located in the diagonal position, connection of the ducts D1-D4 is switched.;COPYRIGHT: (C)2010,JPO&INPIT
