PROBLEM TO BE SOLVED: To enhance the degree of freedom regarding duct piping for a heat- exchanging ventilating device constituted by employing air passage parts on the air supply side and the air exhaust side. SOLUTION: A heat-exchanging ventilating device is provided with an air passage part 1 on the air supply side and an air passage part 12 on the air exhaust side wherein an outlet part 14 extending to the outlet end of an air passage, an inlet part 15 continued to the inlet end of the air passage, and a blower casing part 13 are integrally formed on both sides of the interior of a body casing 2. Outlets continued to the blower casing parts 13 of the air passage part on the air supply side and the air passage part 12 on the air exhaust side are opened in two directions of one being an air supply direction from the blower casing part 13 and the other being a direction extending orthogonally thereto. The inlet part 15 is opened in two directions in a similar manner described above. An outlet end 27 of an exhaust air passage and an inlet end 24 of a supply air passage 4 are situated in a manner to be selectively opened and closed in two directions corresponding to the openings in the two directions of the outlet part 14 and the two directions of the inlet part 15. |
