<P>PROBLEM TO BE SOLVED: To provide a simultaneous supply/exhaust type heat exchange ventilation device that can stably control a constant air volume with high accuracy and shortening a maintenance time of an air volume sensor for air supply and an air volume sensor for exhaust. <P>SOLUTION: This ventilation device includes an exhaust flue for exhausting the indoor air outdoors and an air supply flue for supplying the outdoor air indoors, respectively disposed in a box-shaped body housing 1, an air blower 3 for exhausting disposed in the exhaust flue, an air blower 2 for air supplying disposed in the air supply flue, an exhaust-side blade casing block 10 disposed on the air blower 3 for exhausting and forming the exhaust flue, an air supply-side blade casing block 11 disposed on the air blower 2 for air supplying and forming the air supply flue, and a heat exchanger 5 disposed on an intersecting part of the exhaust flue and the air supply flue, and exchanging heat between the indoor air and the outdoor air. The air blower 2 for air supplying and the air blower 3 for exhausting are disposed at a downstream side of the heat exchanger 5, and the air volume sensor 29 for air supply, is disposed at a suction port side of the air supply-side blade casing block 11. <P>COPYRIGHT: (C)2013,JPO&INPIT |
