PROBLEM TO BE SOLVED: To install a heat exchange type ventilating unit in such a way that the fine outside and inside views of a room are not spoiled by installing the unit by utilizing the space between a curtain box and a ceiling material. SOLUTION: The indoor side of a heat-exchange type ventilating unit 12 is provided in the space between a curtain box 14 and a ceiling material 17 so that the indoor side may be communicated with a room and an external wall opening 22 is formed through an external wall material 19 facing the outdoor surface of the unit 12 and connected to the outdoor side of the unit 12 through a supply and exhaust coupling 24. Therefore, the fine inside and outside views of the room are not spoiled, because the unit 12 is not protruded to the outside nor inside of the room. |
