PROBLEM TO BE SOLVED: To provide a heat exchange type ventilation device in which the number of components is suppressed, which has a structure easy for assembly and in which an insulation structure is optimized.SOLUTION: An exterior box 5 includes: a top plate 9 for configuring an upper surface; a bottom plate 10 for configuring a lower surface; a first outer plate 31 for configuring an outside air side front surface, an outside air side lateral surface on which an outside air port 1 and an exhaust air port 2 are formed and an outside air side back surface; a second outer plate 32 for configuring an inside air side front surface, an inside air side lateral surface on which an air supply port 3 and a return air port 4 are formed and an inside air side back surface; a third outer plate 33 for configuring a partition surface which partitions the front surface between the outside air side front surface and the inside air side front surface and the back surface between the outside air side back surface and the inside air side back surface and the inside into a total heat exchange region a in which a heat exchange element is arranged and the other region; and a partition plate 34 for partitioning the other region into a humidification region b in which a humidifier is arranged and an indoor air passage region c in which an exhaust air flow before heat exchange passes through. |
