It In this way, since the exhaust flow does not pass through the heat exchanger (10), the resistance in the ventilation passage is reduced, and sufficient normal ventilation is performed. Although the heat exchanger (10) becomes dirty and needs to be cleaned by performing the air conditioning ventilation or the normal ventilation as described above, the first maintenance cover (35) provided on the box body (1) is removed to perform heat exchange. It can be cleaned with a vacuum cleaner etc. by pulling out the device (10), and this heat exchanger (10) is inserted and removed in the direction of formation of the suction ports (2) (3) and the air outlets (4) (5). Since it is performed so as to be orthogonal to each other, the piping for air supply and exhaust does not interfere. Further, since the rotating shafts of the exhaust blower (8) and the air supply blower (9) are provided orthogonally to the insertion / removal direction of the heat exchanger (10), a large-sized vane casing (11) Will be arranged in parallel with the heat exchanger (10),
The depth of the box (1) becomes smaller. The width dimension is a heat exchanger
Determined by the dimension of (10). In this way the heat exchanger (10)
When the heat exchanger (10) cannot be inserted / removed due to the structure of the building in this insertion / removal direction, the side plate (33), the first maintenance as shown in Figs. 5 and 6 If the cover (35) and the second maintenance cover (37) are exchanged, the heat exchanger (10) can be inserted and removed in a different direction. Further, since the bypass passage is provided in the second maintenance cover (37), its manufacture is easy.

In the above embodiment, one side of the insertion / removal opening (32) is attached to the side plate (33).
And the first maintenance cover (35) and the other is covered with the second maintenance cover (37), both of which have substantially the same shape as the second maintenance cover (37) as shown in FIG. Formed and one second maintenance cover
The opening (39) may be omitted only in (37).

Also, the damper (14) is the box (1) and the second maintenance cover.
The damper (14) may be provided on any one of (37), but when the damper (14) is provided on the second maintenance cover (37), as described above,
Maintenance cover (35) and second maintenance cover (37)
Since the damper (14) is also replaced at the same time by simply replacing and, it becomes easy to replace the bypass passage (13), and the same air passage switching operation can be performed regardless of which passage is provided with the maintenance cover.

Further, the second maintenance cover (37) is formed to be the same,
A bypass passage (13) may be formed in both the exhaust passage (6) and the air supply passage (7).

Furthermore, the damper (14) may be rotated by the connector (15) and the driving machine (16) as in the conventional case.
