Since the air supply duct 111 and the exhaust duct 112 are parallel to the stacking direction of the partition plates 105 of the heat exchange element 107 and perpendicular to the stacking direction of the partition plates 105 of the heat exchange element 107, the air supply duct 111 and exhaust duct 112
The width E of the heat exchanger main body 101 in the direction perpendicular to these ducts is large, and if it is attempted to be installed in the ceiling of a house, it will not be possible to install it in a house with narrow gaps such as the beams 116. However, the problem was that it was impossible and the scope of application was narrow. In addition, from the point of view of effective use of space in houses, ceiling dimensions are on the decline.
There is a demand for a thin, small, and low-noise heat exchange device, but in order to make it thin, in the conventional configuration, instead of reducing the area of the partition plates 105 of the heat exchange element 107, the number of partition plates 105 is reduced. Although it is possible to increase the length of the heat exchange element 107 by increasing the length of the heat exchange element 107, the width E of the ventilation device body 101 increases (as the length of the passage becomes longer and the pressure loss increases). Thick (and air supply fan 103
Since the load on the fan of the exhaust fan 104 increases, it is difficult to downsize the fan, and the heat exchange air device 10
1, it is difficult to obtain a heat exchange air device that is thinner, smaller, and has lower noise.

The outside air A sucked in through the air supply duct 9 by the air supply fan 3 rotated by the motor 2 is discharged from the outlet of the air supply fan 3, and a part of it is heated. A part of the air enters the exchange element 5 directly, and a part of the air flows along the heat exchange element inlet side F of the air supply passage extending in the overlapping direction of the partition plates 6 of the heat exchange element 5, and enters the heat exchange element 5 at an appropriate position. After entering the air, it reaches the outlet of the heat exchange element 5 and becomes an air flow B that is discharged into the room from the outlet 14 of the cassette louver 12 with the diameter of the heat exchange element outlet example G of the air supply passage. , passes through the suction port 13 of the cassette louver 12 and is sucked into the exhaust fan 4,
Part of the air discharged from the exhaust fan 4 directly enters the heat exchange element 5, and part of the air enters the heat exchange element population 11 of the exhaust passage extending in the overlapping direction of the partition plates 6 of the heat exchange element 5.
1H and enters the heat exchange element 5 at an appropriate position. Then, when passing through the heat exchange element 5, after exchanging heat with the outside air A, the air is collected at the heat exchange element outlet fI4I of the exhaust passage extending in the overlapping direction of the partition plates 6 of the heat exchange element 5, and into this passage. After flowing along the line, the air is discharged outdoors through the exhaust duct 11. Here, the air supply fan 3 and the exhaust fan 4 are substantially coaxial, and the air supply duct 9 is also substantially coaxial. In addition, the exhaust duct 11 is parallel to the overlapping direction of the partition plates 6 of the heat exchange element 5, and the air supply duct 9 and the exhaust duct 11 are parallel, so the interval between these ducts can be narrowed. As a result, the width E of the heat exchange device main body 1 can also be reduced.In addition, the overall area of the partition plates 11 of the heat exchange element 5 is kept the same, and instead of reducing the area of each partition plate, By increasing the number of heat exchange elements 5, that is, by lengthening the heat exchange elements 5 in the longitudinal direction J of the heat exchange apparatus main body 1, the width E of the heat exchange apparatus main body 1 can be further narrowed.

隔が狭い住宅に対しても設置が可能となる。Effects of the Invention As is clear from the description of the embodiments above, according to the present invention, an air supply fan and an exhaust fan are coaxially arranged, and a heat exchange element is partitioned in the direction of discharge from both the fans. The overlapping direction of the plates is located at right angles, and the connection direction of the air supply duct and the exhaust duct is parallel to the overlapping direction of the partition plates of the heat exchange element, so the width of the heat exchange device main body is small. This makes it possible to install it even in homes where the spacing between beams in the ceiling of the home is narrow.

どの効果をもたらす熱交換気装置を提供できる。Furthermore, since a rectifying plate is provided in the fan outlet and the passage on the heat exchange element inlet side, the air flowing into the heat exchange element is made uniform, the heat exchange element is effectively utilized, and the size is reduced. It is possible to provide a heat exchange air device that brings about effects such as being able to obtain a small and thin device.
