なる。The ceiling-mounted heat exchange ventilation system of this example configured as described above can simultaneously exhaust indoor air to the outdoors and supply outdoor air indoors through the heat exchange element 10 on the ceiling side. It is possible to perform ventilation that suppresses fluctuations in state variables such as temperature. In addition, when heat exchange ventilation is not required, such as in the middle of the season, or when you want to quickly exhaust cigarette smoke, etc., you can close the damper 2o and open the switching damper 13 to open the bypass passage 3. The indoor air suction port 9 and the suction side of the exhaust blower 11 are connected through the bypass passage 3, and exhaust can be exhausted without passing through the heat exchange element 10.

When the heat exchange element 10 is removed from the indoor air suction port 9, the indoor air inflow side of the heat exchange element 10 is exposed to the indoor air suction port 9. Therefore, maintenance work on the heat exchange element 10 can be performed using a suction cleaner or the like without removing the heat exchange element 10. The air inlet side of the other air filter 15 and heat exchange element 10 can also be cleaned by opening the front end portion 14 of the shielding plate 4 by rotating it toward the indoor air intake port 9.
If the air filter 15 is exposed and removed from the indoor air suction port 9, the outside air inflow side of the heat exchange element 10 will be exposed to the indoor air suction port 9.
This can be done by operating from .

Even if the hanging fixture 24 should come off due to damage to the tightening member, the suspended-supported main body outer casing 5 will not fall off unless the suspension fixture 25 comes off. will be prevented from falling. In the final installed state, both the hanging fixture 24 and the suspension fixture 25 are attached to a decorative cover 22 that covers both sides of the main body outer casing 5.
This will minimize the damage to the interior decoration.

Since the suspension fixture prevents this falling off, the outer casing of the main body will not fall unless the suspension fixture also comes off, resulting in high safety. In addition, when working on suspending and fixing the outer casing of the main body, unfixed parts can be temporarily placed on the stepped part of the hanging fixing bracket, making the work easier and ultimately Since the suspension fixing fittings are hidden by the decorative covers that cover both sides of the outer casing of the main body, the decorativeness of the interior is less likely to be impaired and the design is improved.
