The air supply panel 9 and the ring air panel 10 are held by the panel holding portion 11 on the louver frame 14.

The louver 7 has an air supply port 12 on the air supply panel 9 side and a ring air port 13 on the ring air panel 10 side.

Further, the louver 7 has an air passage partition 32 between the main body 1 and the air supply panel 9 and the ring air panel 10. The air passage partition 32 has, for example, a flat plate shape, and partitions the space in which the air supplied to the room flows and the space in which the air exhausted from the room flows, below the main body 1.

The main body 1 and the inspection panel 16 are provided above the ceiling 17.

A part of the louver frame 14, the panel holding portion 11, the air supply panel 9, and the ring air panel 10 are provided below the ceiling 17 and are exposed in the indoor space.

The main body 1 includes a ring air suction port 34 that communicates with the ring air port 13 and sucks indoor air.

The ring air panel 10 is provided directly below the ring air suction port 34.

An outside air port 4 and an exhaust port 5 are provided on the first side surface 28 of the main body 1.

A maintenance panel 15 is provided on the second side surface 29 of the main body 1.

The air supply blower 2 and the exhaust blower 3 are provided in the main body 1.

The air supply blower 2 has an air supply / discharge port 33 that discharges outside air. The air supply / discharge port 33 may be provided so as to face downward and discharge the outside air downward.

The air supply blower 2 blows outdoor air from the outside air port 4 to the air supply port 12. This air flow A passes through the air supply air passage 30 that supplies fresh air into the room.

The exhaust blower 3 blows indoor air from the ring port 13 to the exhaust port 5. This air flow B passes through an exhaust air passage 31 that discharges indoor air to the outside.

In the main body 1, the total heat exchange element 6 is provided at a position where the air supply air passage 30 and the exhaust air passage 31 intersect. The total heat exchange element 6 has a heat recovery function of supplying the amount of heat of the exhaust gas to the supply air or supplying the amount of heat of the supply air to the amount of heat of the exhaust gas.

The air supply panel 9 of the louver 7 includes an extension portion 18 and a non-extension portion 19.

The extension portion 18 is a portion that is extended to a position that protrudes (protrudes) from the second side surface 29 of the main body 1. That is, the extension portion 18 is a portion that is not located directly below the main body 1.

The air supply panel end portion 23 is an end portion of the air supply panel 9 on the air supply port 12 side. The air supply panel end portion 23 may be a part of the extension portion 18.

The non-extension portion 19 is a portion that does not protrude from the second side surface 29. That is, the non-extension portion 19 is a portion located directly below the main body 1.

The louver frame 14 forms an inspection opening 25.

The inspection panel 16 is provided in the inspection opening 25. That is, when the inspection panel 16 is provided in the inspection opening 25, for example, the inspection panel 16 covers the inspection opening 25 from above.

The inspection panel 16 may be removable.

The inspection panel 16 may be opened (removed) during maintenance, and may be closed (attached) when air is supplied from the air supply port, for example.

The inspection opening 25 and the inspection panel 16 are located directly above the extension portion 18.

Here, the air flow in the present embodiment will be described.

The air flow A indicates the flow of outdoor air blown from the outside air port 4 to the air supply port 12 by the air supply blower 2. The air taken in from the outside air port 4 by the air supply blower 2 is discharged from the air supply discharge port 33 and flows in a direction parallel to the ceiling 17. At this time, the air discharged from the air supply port 33 may flow into the room from the air supply port 12 after the traveling direction is changed by hitting the non-extension portion 19 of the air supply panel 9. That is, the air discharged from the air supply / discharge port 33 may flow from the air supply port 12 after passing through the region surrounded by the panel holding portion 11 and the air supply panel 9.

The inspection panel 16 and the louver frame 14 may cover the upper part of the area surrounded by the panel holding portion 11 and the air supply panel 9. That is, the air discharged from the air supply / discharge port 33 may flow through a space partitioned by the inspection panel 16 and the louver frame 14 at the upper portion, the air supply panel 9 at the lower portion, and the panel holding portion 11 at the side portion. ..

The air supply port 12 may not be provided on the non-extension portion 19 side, but may be provided on the extension portion 18 side. As a result, the distance between the main body 1 and the air supply port 12 becomes long. Therefore, the noise generated in the main body 1 of the air supply blower 2 and the exhaust blower 3 is less likely to reach the room.

Further, the air supply port 12 may have an air supply port front portion 26 and an air supply port side surface portion 21. The air supply port front surface portion 26 is a portion that mainly blows air along a direction parallel to the first side surface 28, and the air supply port side surface portion 21 mainly blows air along a direction parallel to the second side surface 29. This is the part that blows out.

By having the air supply port front portion 26 and the air supply port side surface portion 21, air can be blown from a plurality of directions (for example, three directions), and air can be supplied to the room more efficiently.

The air flow B indicates the flow of air in the room that is blown from the ring port 13 to the exhaust port 5 by the exhaust blower 3. The air taken in from the ring air port 13 by the exhaust blower 3 is sucked into the main body 1 from the ring air suction port 34.

The ring air opening 13 may have a ring air opening front surface portion 27 and a ring air opening side surface portion 22. The ring air opening front surface portion 27 is a portion that mainly sucks air along the direction parallel to the first side surface 28, and the ring air opening side surface portion 22 mainly sucks air along the direction parallel to the second side surface 29. This is the part that sucks in.

By having the ring air port front portion 27 and the ring air port side surface portion 22, air can be sucked in from a plurality of directions (for example, three directions), and the air can be exhausted to the outside more efficiently.

Further, the panel holding portion 11 may be provided so as to extend so as to overlap a part of the extension portion 18. That is, the end portion 24 of the panel holding portion may be located at a position protruding from the second side surface 29 and may be located above the extension portion 18. At this time, the panel holding portion end portion 24 is located directly below the inspection opening 25.

Further, the panel holding portion 11 may be provided so as to extend so as to overlap 50% to 95% of the extension portion 18. That is, the end portion 24 of the panel holding portion may be located at a position of 50% to 95% of the extension portion 18 starting from the second side surface 29.

By extending the panel holding portion 11 so as to overlap the extension portion 18, it is possible to reduce the noise reaching the room while ensuring the amount of air blown from the air supply port 12.

The air supply panel 9 and the ring air panel 10 may be integrated. As a result, the design of the heat exchange device can be improved.

Although the heat exchange apparatus according to the present invention has been described above based on the embodiment, the present invention is not limited to this embodiment. As long as the gist of the present invention is not deviated, various modifications that can be conceived by those skilled in the art are applied to the present embodiment, and a form constructed by combining components in different embodiments is also included in the scope of the present invention. ..

Since the heat exchange device according to the present invention improves workability during maintenance, it is also useful for heat exchange devices such as houses and buildings.
