熱交換型換気装置に備えられる熱交換素子の性能の指標となる熱交換効率は、一般に７０％程度であるために、換気に必要な風量が増大するにつれて、熱交換素子も大型にする必要がある。   The heat exchange efficiency, which is an index of the performance of the heat exchange element provided in the heat exchange type ventilator, is generally about 70%. Therefore, as the air volume required for ventilation increases, it is necessary to increase the size of the heat exchange element. is there.

このため、熱交換型換気装置が大型化するという問題があり、部屋の壁に設置される形態の熱交換型換気装置では、室内の美観を損ねてしまう。また、壁に埋め込む形態とした場合、熱交換型換気装置が大型化すると、外気の壁の厚い建物でないと設置できない。   For this reason, there exists a problem that a heat exchange type | mold ventilation apparatus enlarges, and in the heat exchange type | mold ventilation apparatus of the form installed in the wall of a room, the indoor beauty | look will be spoiled. Moreover, when it is set as the form embedded in a wall, if a heat exchange type | mold ventilation apparatus enlarges, it can be installed only if it is a building with a thick wall of outside air.

上述した課題を解決するため、本発明の熱交換型換気装置は、室外の空気を吸入し、外気導入経路を通して室内給気口から室内に給気する給気ファンと、室内吸込口から室内の空気を吸入し、内気排出経路を通して室外へ排気する排気ファンと、隔絶された第１の流路と第２の流路が沿った向きで積層され、第１の流路を外気導入経路と連通させ、第２の流路を内気排出経路と連通させて、室内へ給気される空気と室外へ排気される空気との間で熱交換が行われる熱交換素子とを備え、熱交換素子は、給気ファンで吸入されて第１の流路を通る空気と、排気ファンで吸入されて第２の流路を通る空気の流れる方向を対向流とした熱交換経路が構成されることを特徴とする。   In order to solve the above-described problems, a heat exchange ventilator according to the present invention sucks outdoor air and supplies air from the indoor air supply port into the room through the outside air introduction path, and the indoor intake port to the indoor space. An exhaust fan that sucks in air and exhausts the air through the inside air discharge path, and the separated first and second flow paths are stacked in a direction along the first flow path, and the first flow path communicates with the outside air introduction path. A heat exchange element that communicates heat between the air supplied to the room and the air exhausted to the outside by communicating the second flow path with the inside air discharge path, The heat exchange path is configured such that the air flowing through the first flow path after being sucked by the air supply fan and the air flowing through the second flow path after being sucked by the exhaust fan are opposed to each other. And

これに対して、第１の流路２２ａの吹出口２１ａと、第２の流路２２ｂの吸込口２０ｂは、熱交換素子２Ａの他方の端部に上下方向に分かれて構成される。吹出口２１ａが形成される面は、第１の流路２２ａと対向する部位は開口し、第２の流路２２ｂと対向する部位は塞がれて、吹出口２１ａと第１の流路２２ａが連通する。   On the other hand, the blower outlet 21a of the first flow path 22a and the suction port 20b of the second flow path 22b are configured separately in the vertical direction at the other end of the heat exchange element 2A. The surface on which the air outlet 21a is formed is open at a portion facing the first flow path 22a, and is closed at a portion facing the second flow path 22b, so that the air outlet 21a and the first flow path 22a are closed. Communicate.

また、吸込口２０ｂが形成される面は、第２の流路２２ｂと対向する部位は開口し、第１の流路２２ａと対向する部位は塞がれて、吸込口２０ｂと第２の流路２２ｂが連通する。   Further, the surface on which the suction port 20b is formed is opened at a portion facing the second flow path 22b, and a portion facing the first flow path 22a is closed, so that the suction port 20b and the second flow path are closed. The path 22b communicates.

これにより、熱交換素子２Ａは、吸込口２０ａから吸い込まれた空気が、第１の流路２２ａを通って吹出口２１ａから吹き出し、吸込口２０ｂから吸い込まれた空気が、第２の流路２２ｂを通って吹出口２１ｂから吹き出すことで、第１の流路２２ａを流れる空気と第２の流路２２ｂを流れる空気が対向流となる。   Thereby, in the heat exchange element 2A, the air sucked from the suction port 20a blows out from the blowout port 21a through the first flow path 22a, and the air sucked from the suction port 20b becomes the second flow path 22b. The air flowing through the first flow path 22a and the air flowing through the second flow path 22b are opposed to each other by being blown out from the outlet 21b.

そして、第１の流路２２ａと第２の流路２２ｂが隔壁２４で仕切られていることで、第１の流路２２ａを流れる空気と第２の流路２２ｂを流れる空気との間で熱交換が行われる。   Since the first flow path 22a and the second flow path 22b are partitioned by the partition wall 24, heat is generated between the air flowing through the first flow path 22a and the air flowing through the second flow path 22b. Exchange is performed.

このように、熱交換素子２Ａでは、熱交換される空気が通る第１の流路２２ａと第２の流路２２ｂで、空気の流れを対向流としている。   As described above, in the heat exchange element 2A, the air flow is opposed to the first flow path 22a and the second flow path 22b through which the air to be heat-exchanged passes.

また、熱交換素子２Ａでは、第１の流路２２ａと第２の流路２２ｂは、隔壁２４及び流路形成板２４ａ，２４ｂを熱伝導率の高い金属素材で構成することで、熱交換効率を向上させている。   In the heat exchange element 2A, the first flow path 22a and the second flow path 22b are configured such that the partition wall 24 and the flow path forming plates 24a and 24b are made of a metal material having a high thermal conductivity, so that the heat exchange efficiency can be improved. Has improved.

これにより、熱交換素子２Ａでは、熱交換される空気が通る流路が樹脂素材で構成され、かつ、空気の流れる方向が直交流である直交型の熱交換素子と比較して、第１の流路２２ａと第２の流路２２ｂを積層する数を減らし、かつ、必要な熱交換効率は維持している。   Thereby, in the heat exchange element 2A, the flow path through which the heat exchanged air is made of a resin material, and the first direction of the heat exchange element of the orthogonal type in which the flow direction of the air is an orthogonal flow is The number of stacked channels 22a and second channels 22b is reduced, and the necessary heat exchange efficiency is maintained.

また、隔壁２４及び流路形成板２４ａ，２４ｂを構成する板材は、金属素材とすることで、強度を落とすことなく板厚を薄くしている。   Moreover, the plate | board material which comprises the partition 24 and the flow-path formation board 24a, 24b is made into a metal raw material, and is reducing plate | board thickness, without reducing intensity | strength.

従って、熱交換素子２Ａは、直交型の熱交換素子と比較して、第１の流路２２ａと第２の流路２２ｂが積層される方向の幅が薄く抑えられる。   Therefore, in the heat exchange element 2A, the width in the direction in which the first flow path 22a and the second flow path 22b are stacked is reduced compared to the orthogonal heat exchange element.

なお、並列した第１の流路２２ａの間を貫通する図示しないスリットを流路形成板２４ａに形成すると共に、並列した第２の流路２２ｂの間を貫通する図示しないスリットを流路形成板２４ｂに形成することで、空気の流れに乱流を発生させ、熱交換効率を向上させることができる。   A slit (not shown) penetrating between the parallel first flow paths 22a is formed on the flow path forming plate 24a, and a slit (not shown) penetrating between the parallel second flow paths 22b is formed on the flow path forming plate. By forming in 24b, a turbulent flow can be generated in the air flow and the heat exchange efficiency can be improved.

ここで、熱交換素子２Ａの一方の端部に形成される吸込口２０ａと吹出口２１ｂは、上下に別れて六角形状の異なる面に配置されることで、簡単な構成で外気導入経路３と内気排出経路４が確実に分離され、第１の流路２２ａに吸い込まれる空気と第２の流路２２ｂから吹き出す空気は混合しない。   Here, the suction port 20a and the blower port 21b formed at one end of the heat exchange element 2A are separated from each other vertically and arranged on different hexagonal surfaces, so that the outside air introduction path 3 can be easily configured. The inside air discharge path 4 is reliably separated, and the air sucked into the first flow path 22a and the air blown out from the second flow path 22b are not mixed.

同様に、熱交換素子２Ａの他方の端部に形成される吹出口２１ａと吸込口２０ｂは、上下に別れて六角形状の異なる面に配置されることで、簡単な構成で外気導入経路３と内気排出経路４が確実に分離され、第１の流路２２ｂから吹き出す空気と第２の流路２２ｂに吸い込まれる空気は混合しない。   Similarly, the air outlet 21a and the inlet 20b formed at the other end of the heat exchange element 2A are separated from each other vertically and arranged on different hexagonal surfaces, so that the outside air introduction path 3 can be easily configured. The inside air discharge path 4 is reliably separated, and the air blown out from the first flow path 22b and the air sucked into the second flow path 22b are not mixed.

＜熱交換素子を着脱可能とした構成例＞
図５は、熱交換素子２Ａの着脱構成を示す斜視図である。熱交換素子２Ａは、ケース２４ｄの正面に着脱タブ２４ｅを備える。着脱タブ２４ｅを引き起こすことで、セル２４ｃの着脱が可能である。また、熱交換素子２Ａ全体が、換気装置１Ａの素子取付部１２に対して着脱可能で、これにより、熱交換素子２Ａのメンテナンスやセル２４ｃの交換等が可能である。 <Example of configuration in which the heat exchange element is removable>
FIG. 5 is a perspective view showing a configuration for attaching and detaching the heat exchange element 2A. The heat exchange element 2A includes a detachable tab 24e on the front surface of the case 24d. By causing the attachment / detachment tab 24e, the attachment / detachment of the cell 24c is possible. In addition, the entire heat exchange element 2A can be attached to and detached from the element mounting portion 12 of the ventilation device 1A, whereby maintenance of the heat exchange element 2A, replacement of the cell 24c, and the like are possible.

＜第１の実施の形態の熱交換型換気装置の設置例＞
図６は、第１の実施の形態の換気装置１Ａの設置例を示す構成図、図７は、換気装置１Ａが設置された建物の一例を示す構成図で、次に、第１の実施の形態の換気装置１Ａの設置例について説明する。 <Installation example of the heat exchange type ventilator according to the first embodiment>
FIG. 6 is a configuration diagram showing an installation example of the ventilation device 1A of the first embodiment, and FIG. 7 is a configuration diagram showing an example of a building in which the ventilation device 1A is installed. Next, the first embodiment An installation example of the ventilator 1 </ b> A in the form will be described.

換気装置１Ａは、建物５０において、居室等の部屋５１の壁５２に設置される。換気装置１Ａが設置される部屋５１の壁５２には、換気装置１Ａに取り付けられている給排気ダクト１３を通す壁穴５２ａが開けられる。   The ventilation device 1A is installed on a wall 52 of a room 51 such as a living room in a building 50. A wall hole 52a through which the air supply / exhaust duct 13 attached to the ventilation device 1A is passed is formed in the wall 52 of the room 51 where the ventilation device 1A is installed.

換気装置１Ａは、壁穴５２ａに給排気ダクト１３を通し、壁５２の内壁側に掛ける形態で取り付けられる。これにより、換気装置１Ａは、部屋５１の室内に面した正面に室内給気口３２が配置されると共に、壁５２に面した側面に室内吸込口４１が配置される。   The ventilation device 1 </ b> A is attached in such a manner that the air supply / exhaust duct 13 is passed through the wall hole 52 a and hung on the inner wall side of the wall 52. Thus, in the ventilator 1 </ b> A, the indoor air supply port 32 is disposed on the front surface facing the room 51, and the indoor suction port 41 is disposed on the side surface facing the wall 52.

換気装置１Ａを設置する壁５２は、外壁側が屋外に面しており、壁穴５２ａは、壁５２を貫通して開けられているので、換気装置１Ａは、外気吸込口３１と排気口４２が給排気ダクト１３を介して屋外と連通している。   The wall 52 on which the ventilator 1A is installed has an outer wall facing the outdoors, and the wall hole 52a is opened through the wall 52. Therefore, the ventilator 1A has the outside air inlet 31 and the exhaust port 42. It communicates with the outside through the air supply / exhaust duct 13.

これにより、換気装置１Ａは、天井へのダクト等の設置を行わず、外気の取り入れ及び室内からの給気の排気が行える構成である。なお、換気装置１Ａは、自機が設置された部屋５１の換気を行う能力を有する。   Thereby, 1 A of ventilation apparatuses are the structures which can take in external air and exhaust the supply air from room | chamber interior, without installing the duct etc. to a ceiling. In addition, 1 A of ventilation apparatuses have the capability to ventilate the room 51 in which the own machine was installed.

ここで、換気装置１Ａは、熱交換経路２３を対向流とし、また、熱交換素子２Ａにおいて第１の流路２２ａと第２の流路２２ｂを積層する数を減らしており、換気装置１Ａでは、熱交換素子２Ａにおいて、第１の流路２２ａと第２の流路２２ｂの積層方向の幅を、直交型の熱交換素子より薄くすることができる。従って、直交型の熱交換素子を使用する場合と比較して、換気装置１Ａの奥行き方向の厚みを薄く抑えることができる。   Here, the ventilation device 1A uses the heat exchange path 23 as a counterflow, and reduces the number of first flow paths 22a and second flow paths 22b stacked in the heat exchange element 2A. In the heat exchange element 2A, the width in the stacking direction of the first flow path 22a and the second flow path 22b can be made thinner than that of the orthogonal heat exchange element. Therefore, compared with the case where an orthogonal type heat exchange element is used, the thickness of the ventilator 1A in the depth direction can be reduced.

よって、壁５２からの突出量が少なくなり、室内で目立ちにくくなって、室内の美観が向上する。   Therefore, the amount of protrusion from the wall 52 is reduced, it is less noticeable in the room, and the indoor aesthetics are improved.

なお、換気装置１Ａは、奥行き方向の厚みが薄く抑えられることで、外壁の薄い建物であっても、図示しないが壁に埋め込む形態で設置が可能となる。   Note that the ventilation device 1A can be installed in a form that is embedded in a wall (not shown), even if the building has a thin outer wall, by suppressing the thickness in the depth direction to be thin.

＜第１の実施の形態の熱交換型換気装置の動作例＞
次に、各図を参照して第１の実施の形態の換気装置１Ａの動作について説明する。 <Operation example of the heat exchange type ventilator according to the first embodiment>
Next, the operation of the ventilation device 1A according to the first embodiment will be described with reference to the drawings.

換気装置１Ａは、ファンモータ３３ａにより給気ファン３３が回転駆動されると、外気導入経路３において、外気吸込口３１から空気を吸入して、室内給気口３２から給気する空気の流れが発生する。   In the ventilator 1A, when the air supply fan 33 is rotationally driven by the fan motor 33a, the flow of air supplied from the indoor air intake port 32 is sucked in from the outside air intake port 31 in the outside air introduction path 3. appear.

これにより、ケース１１の背面側の外気吸込口３１から、給排気ダクト１３を介して外気ＯＡが吸入され、外気吸込口３１から吸入された外気ＯＡは、外気導入経路３を通り、熱交換素子２Ａの一方の端部において吸込口２０ａに送り込まれる。   As a result, the outside air OA is sucked from the outside air suction port 31 on the back side of the case 11 through the air supply / exhaust duct 13, and the outside air OA sucked from the outside air suction port 31 passes through the outside air introduction path 3 and becomes a heat exchange element. It is fed into the suction port 20a at one end of 2A.

熱交換素子２Ａの吸込口２０ａに送り込まれた外気ＯＡは、第１の流路２２ａを通り、他方の端部側において吹出口２１ａから吹き出す。熱交換素子２Ａの吹出口２１ａから吹き出した外気ＯＡは、給気風向調整部材３４により風向がケース１１の正面側に向けられて、ケース１１の正面側の室内給気口３２から、給気ＳＡとして前方へ向けて吹き出される。   The outside air OA sent to the suction port 20a of the heat exchange element 2A passes through the first flow path 22a and blows out from the blowout port 21a on the other end side. The outside air OA blown out from the air outlet 21a of the heat exchange element 2A is directed toward the front side of the case 11 by the air supply air direction adjusting member 34, and supplied from the indoor air supply port 32 on the front side of the case 11 to the air supply SA. And blown out forward.

また、換気装置１Ａは、ファンモータ４３ａにより排気ファン４３が回転駆動されると、内気排出経路４において、室内吸込口４１から空気を吸入して、排気口４２から排出する空気の流れが発生する。   Further, in the ventilator 1A, when the exhaust fan 43 is rotationally driven by the fan motor 43a, in the inside air discharge path 4, a flow of air that is sucked from the indoor suction port 41 and discharged from the exhaust port 42 is generated. .

これにより、室内からの還気ＲＡが、吸込風向調整部材４４によってケース１１の側面後方側から廻り込むようにして、室内吸込口４１から吸入される。室内吸込口４１から吸入された還気ＲＡは、内気排出経路４を通り、熱交換素子２Ａの他方の端部において吸込口２０ｂから吸い込まれる。   Thus, the return air RA from the room is sucked from the indoor suction port 41 so as to go around from the rear side of the side surface of the case 11 by the suction air direction adjusting member 44. The return air RA sucked from the indoor suction port 41 passes through the inside air discharge path 4 and is sucked from the suction port 20b at the other end of the heat exchange element 2A.

熱交換素子２Ａの吸込口２０ｂに吸い込まれた還気ＲＡは、第２の流路２２ｂを通り、一方の端部において吹出口２１ｂから吹き出す。熱交換素子２Ａの吹出口２１ｂから吹き出した還気ＲＡは、ケース１１の背面側の排気口４２から、給排気ダクト１３を介して排気ＥＡとして排出される。   The return air RA sucked into the suction port 20b of the heat exchange element 2A passes through the second flow path 22b and blows out from the blowout port 21b at one end. The return air RA blown out from the air outlet 21b of the heat exchange element 2A is exhausted from the exhaust port 42 on the back side of the case 11 as exhaust EA through the air supply / exhaust duct 13.

さて、空気調和された室内の空気は、夏季は外気より温度が低く、冬季は外気より温度が高い。熱交換素子２Ａでは、第１の流路２２ａを通る外気ＯＡと第２の流路２２ｂを通る室内からの還気ＲＡの間で熱交換が行われることで、夏季は、温度の高い外気と冷却された室内の空気との間で熱交換が行われ、外気ＯＡの温度が下げられる。また、冬季は、温度の低い外気と暖房された室内の空気との間で熱交換が行われ、外気ＯＡの温度が上げられる。   Now, the air in the air-conditioned room has a lower temperature than the outside air in summer and a higher temperature than the outside air in winter. In the heat exchange element 2A, heat exchange is performed between the outside air OA passing through the first flow path 22a and the return air RA from the room passing through the second flow path 22b. Heat exchange is performed with the cooled indoor air, and the temperature of the outside air OA is lowered. In winter, heat is exchanged between the low temperature outside air and the heated indoor air, and the temperature of the outside air OA is raised.

これにより、換気装置１Ａでは、外気を室内の温度に近づけて、給気を行いながら室内の換気を行うことができる。   Thereby, in the ventilator 1A, it is possible to ventilate the room while supplying air by bringing the outside air close to the room temperature.

上述したように、熱交換素子２Ａでは、第１の流路２２ａを通る外気ＯＡと第２の流路２２ｂを通る室内からの還気ＲＡを対向流としている。また、第１の流路２２ａと第２の流路２２ｂは、熱伝導率の高い金属素材で構成されることで、熱交換効率を向上させている。   As described above, in the heat exchange element 2A, the outside air OA passing through the first flow path 22a and the return air RA from the room passing through the second flow path 22b are used as counterflows. Moreover, the 1st flow path 22a and the 2nd flow path 22b are improving the heat exchange efficiency by being comprised with a metal material with high heat conductivity.

これにより、熱交換素子２Ａは、第１の流路２２ａと第２の流路２２ｂを積層する数を減らしても、必要な熱交換効率を得ることができ、換気装置１Ａは、図７に示すような自機が設置される部屋５１の換気に必要な風量を確保しつつ、薄型化が可能である。   As a result, the heat exchange element 2A can obtain the necessary heat exchange efficiency even if the number of the first flow paths 22a and the second flow paths 22b stacked is reduced. It is possible to reduce the thickness while securing the air volume necessary for ventilation of the room 51 where the own machine is installed.

また、第１の実施の形態の換気装置１Ａでは、空気を吹き出す室内給気口３２が正面に配置されると共に、空気を吸い込む室内吸込口４１が側面に配置され、更に、室内吸込口４１から吸い込まれる空気は、吸込風向調整部材４４によって図７に示す壁５２に沿って後方側から廻り込む。   Moreover, in 1 A of ventilation apparatus of 1st Embodiment, while the indoor air supply port 32 which blows off air is arrange | positioned in the front, the indoor air intake port 41 which inhales air is arrange | positioned at the side surface, Furthermore, from the indoor air intake port 41, The sucked air flows from the rear side along the wall 52 shown in FIG.

これにより、室内給気口３２から吹き出す空気が室内吸込口４１から吸い込まれるショートサーキットを抑えることができる。   Thereby, the short circuit in which the air which blows off from the indoor air supply port 32 is sucked in from the indoor suction port 41 can be suppressed.

ここで、イオン発生器１５で略同数の正イオンと負イオンを発生させ、略同数の正イオンと負イオンを含む空気を送風することで、給気ＳＡに含まれる浮遊細菌等が除去され、カビの発生等を抑えることができる。   Here, by generating approximately the same number of positive ions and negative ions in the ion generator 15 and blowing air containing approximately the same number of positive ions and negative ions, suspended bacteria contained in the supply air SA are removed, Generation of mold and the like can be suppressed.

＜第１の実施の形態の熱交換型換気装置の変形例＞
換気装置１Ａでは、室内給気口３２に備えた給気風向調整部材３４を、向きが可変となる電動ルーバとすることで、室内給気口３２からの空気の吹き出し方向を任意の方向に切り替えたり、スイングさせたりすることができる。 <Modification of the heat exchange type ventilator according to the first embodiment>
In the ventilation device 1A, the air supply direction adjustment member 34 provided in the indoor air supply port 32 is an electric louver whose direction is variable, so that the direction of blowing air from the indoor air supply port 32 can be switched to an arbitrary direction. Or swing.

また、本例では、室内給気口３２を換気装置１Ａの正面に設置したが、室内給気口３２は、換気装置１Ａの上面または下面、あるいは上下両面に設置する構成として、換気装置１Ａの上方または下方、あるいは上下両方に空気が吹き出されるようにしても良い。   In this example, the indoor air inlet 32 is installed in front of the ventilator 1A. However, the indoor air inlet 32 is installed on the upper surface or lower surface of the ventilator 1A, or on both upper and lower surfaces. Air may be blown out upward, downward, or both above and below.

換気装置１Ａの上面または下面、あるいは上下両面に室内給気口３２を設置する構成では、装置正面側から室内給気口３２を見えなくすることができ、外観性が向上する。また、室内吸込口４１が上述したように装置側面に設置されることで、ショートサーキットを抑えることができる。   In the configuration in which the indoor air supply ports 32 are installed on the upper surface or the lower surface or both the upper and lower surfaces of the ventilation device 1A, the indoor air supply ports 32 can be made invisible from the front side of the device, and the appearance is improved. Moreover, a short circuit can be suppressed because the indoor suction port 41 is installed on the side of the apparatus as described above.

＜シャッタの開閉動作例＞
図８は、外気吸込口３１と排気口４２を開閉するシャッタ１４の動作説明図である。 <Example of shutter opening / closing operation>
FIG. 8 is an operation explanatory view of the shutter 14 that opens and closes the outside air inlet 31 and the exhaust port 42.

シャッタ１４は、外気吸込口３１を開閉する給気側シャッタ１４ａと、排気口４２を開閉する排気側シャッタ１４ｂを独立して備え、レバー１４ｃの動作が、図示しない駆動力伝達機構を介して伝達されて、例えば回転運動で開閉する。   The shutter 14 includes an air supply side shutter 14a that opens and closes the outside air inlet 31 and an exhaust side shutter 14b that opens and closes the exhaust port 42, and the operation of the lever 14c is transmitted via a driving force transmission mechanism (not shown). For example, it opens and closes by rotational movement.

図８（ａ）では、外気吸込口３１と排気口４２の双方を全閉した状態を示す。外気吸込口３１を給気側シャッタ１４ａで閉じ、排気口４２を排気側シャッタ１４ｂで閉じることで、換気運転停止時の外気の侵入を防ぐ。   FIG. 8A shows a state in which both the outside air intake port 31 and the exhaust port 42 are fully closed. The outside air inlet 31 is closed by the supply side shutter 14a, and the exhaust port 42 is closed by the exhaust side shutter 14b, thereby preventing outside air from entering when the ventilation operation is stopped.

図８（ｂ）では、外気吸込口３１と排気口４２の双方を全開した状態を示す。給気側シャッタ１４ａと排気側シャッタ１４ｂを全開すると、例えば重なり合った位置に退避する構成として、シャッタの開閉に必要なスペースを小さくしている。   FIG. 8B shows a state where both the outside air intake port 31 and the exhaust port 42 are fully opened. When the supply-side shutter 14a and the exhaust-side shutter 14b are fully opened, for example, the space required for opening and closing the shutter is reduced by retracting to the overlapping position.

図８（ｃ）では、外気吸込口３１と排気口４２の双方を半開した状態を示す。また、図８（ｄ）では、外気吸込口３１を半開し、排気口４２を全開した状態を示す。更に、図８（ｅ）では、外気吸込口３１を全開し、排気口４２を半開した状態を示す。このように、給気側シャッタ１４ａと排気側シャッタ１４ｂの開度を調整することで、換気回数の調整が可能である。   FIG. 8C shows a state where both the outside air intake port 31 and the exhaust port 42 are half opened. FIG. 8D shows a state where the outside air inlet 31 is half-opened and the exhaust port 42 is fully opened. Further, FIG. 8E shows a state where the outside air inlet 31 is fully opened and the exhaust port 42 is half-opened. In this manner, the number of ventilations can be adjusted by adjusting the opening degree of the supply side shutter 14a and the exhaust side shutter 14b.

図８（ｆ）では、外気吸込口３１は全開し、排気口４２は全閉した状態を示す。これにより、機械による給気と自然排気を組み合わせた２種換気が行われる。   FIG. 8F shows a state in which the outside air inlet 31 is fully opened and the exhaust port 42 is fully closed. As a result, two types of ventilation are performed in combination with mechanical air supply and natural exhaust.

図８（ｇ）では、外気吸込口３１は全閉し、排気口４２は全開した状態を示す。これにより、自然給気と機械による排気を組み合わせた３種換気が行われる。   In FIG. 8G, the outside air inlet 31 is fully closed and the exhaust port 42 is fully open. Thereby, 3 types of ventilation which combined natural supply and exhaust with a machine is performed.

＜第２の実施の形態の熱交換型換気装置の構成例＞

FIGS. 9 and 10 are configuration diagrams showing an example of a heat exchange type ventilator according to the second embodiment, and FIG. 9A shows an internal configuration of the ventilator 1B according to the second embodiment. FIG. 9B is a plan view showing the internal configuration of the ventilation device 1B, and FIG. 10 is a perspective view showing a heat exchange element 2B according to another embodiment.

ここで、以下の説明では、第１の実施の形態の換気装置１Ａと同等の構成の部品については、同じ番号を付して詳細な説明は省略する。   Here, in the following description, the same number is attached | subjected about the component of the structure equivalent to 1 A of ventilation apparatuses of 1st Embodiment, and detailed description is abbreviate | omitted.

第２の実施の形態の換気装置１Ｂは、室内給排部１１ｂの他の実施の形態を示し、ケース１１の側面に室内給気口３２が形成されると共に、ケース１１の上面もしくは下面のどちらか一方あるいは両方に室内吸込口４１が形成される。   The ventilator 1B of the second embodiment shows another embodiment of the indoor supply / exhaust part 11b, and an indoor air supply port 32 is formed on the side surface of the case 11, and either the upper surface or the lower surface of the case 11 is formed. An indoor suction port 41 is formed in one or both of them.

熱交換素子２Ｂは、空気の流れを対向流とした第１の流路２２ａと第２の流路２２ｂを備え、第２の流路２２ｂの間に隔壁を介して第１の流路２２ａを挟んで構成される例えば３層構造で、第１の流路２２ａの他方の端部側に風路形成部材２５が例えば一体に形成される。   The heat exchange element 2B includes a first flow path 22a and a second flow path 22b in which the air flow is a counter flow, and the first flow path 22a is provided between the second flow path 22b via a partition wall. For example, the air path forming member 25 is integrally formed on the other end side of the first flow path 22a, for example, in a three-layer structure sandwiched therebetween.

熱交換素子２Ｂは、風路形成部材２５が室内給排部１１ｂに突出して、室内給気口３２と接続される。これにより、室内給排部１１ｂは、風路形成部材２５により還気導入部１１ｒと仕切られた外気給気部１１ｓが構成される。   In the heat exchange element 2B, the air passage forming member 25 protrudes from the indoor supply / exhaust portion 11b and is connected to the indoor air supply port 32. As a result, the indoor air supply / exhaust portion 11b includes an outside air supply portion 11s partitioned from the return air introduction portion 11r by the air passage forming member 25.

熱交換素子２Ｂの第１の流路２２ａは、風路形成部材２５を介して吹出口２１ａが室内給気口３２と連通する。また、第２の流路２２ｂは、還気導入部１１ｒを構成する空間を介して吸込口２０ｂが室内吸込口４１と連通する。   In the first flow path 22 a of the heat exchange element 2 </ b> B, the air outlet 21 a communicates with the indoor air inlet 32 via the air path forming member 25. In addition, in the second flow path 22b, the suction port 20b communicates with the indoor suction port 41 through a space constituting the return air introduction part 11r.

なお、熱交換素子２Ｂの一方の端部側は、図２（ｂ）に示す構造と同様に、第１の流路２２ａの吸込口２０ａと、第２の流路２２ｂの吹出口２１ｂが上下方向に分かれて構成される。   Note that, on the one end side of the heat exchange element 2B, similarly to the structure shown in FIG. 2B, the suction port 20a of the first flow path 22a and the air outlet 21b of the second flow path 22b are vertically moved. Divided into directions.

＜第２の実施の形態の熱交換型換気装置の動作例＞
次に、各図を参照して第２の実施の形態の換気装置１Ｂの動作について説明する。 <Operation example of the heat exchange type ventilator of the second embodiment>
Next, the operation of the ventilation device 1B according to the second embodiment will be described with reference to the drawings.

換気装置１Ｂは、ファンモータ３３ａにより給気ファン３３が回転駆動されると共に、ファンモータ４３ａにより排気ファン４３が回転駆動される。   In the ventilation device 1B, the air supply fan 33 is rotationally driven by the fan motor 33a, and the exhaust fan 43 is rotationally driven by the fan motor 43a.

外気導入経路３側では、給気ファン３３が回転駆動されると、ケース１１の背面に形成された外気吸込口３１から、給排気ダクト１３を介して外気ＯＡが吸入される。   On the outside air introduction path 3 side, when the air supply fan 33 is driven to rotate, outside air OA is sucked from the outside air inlet 31 formed on the back surface of the case 11 through the air supply / exhaust duct 13.

外気吸込口３１から吸入された外気ＯＡは、熱交換素子２Ｂの一方の端部側で吸込口２０ａから送り込まれて第１の流路２２ａを通り、風路形成部材２５を介して他方の端部側で吹出口２１ａから吹き出すことで、ケース１１の側面の室内給気口３２から、給気ＳＡとして側方へ向けて吹き出される。   The outside air OA sucked from the outside air suction port 31 is sent from the suction port 20a on one end side of the heat exchange element 2B, passes through the first flow path 22a, and passes through the air passage forming member 25 to the other end. By blowing from the blower outlet 21a on the part side, the air is blown out sideways as the air supply SA from the indoor air supply port 32 on the side surface of the case 11.

内気排出経路４側では、排気ファン４３が回転駆動されると、ケース１１の上面と下面の何れかあるいは双方に形成された室内吸込口４１を通して、ケース１１の上方と下方の何れかあるいは双方から、室内からの還気ＲＡが吸入される。   On the inside air discharge path 4 side, when the exhaust fan 43 is rotationally driven, it passes through the indoor suction port 41 formed on either or both of the upper surface and the lower surface of the case 11 and from either or both above and below the case 11. The return air RA from the room is inhaled.

室内吸込口４１から吸入された還気ＲＡは、熱交換素子２Ｂの他方の端部側で吸込口２０ｂから吸い込まれて第２の流路２２ｂを通り、一方の端部側で吹出口２１ｂから吹き出すことで、ケース１１の背面の排気口４２から、給排気ダクト１３を介して排気ＥＡとして排出される。   The return air RA sucked from the indoor suction port 41 is sucked from the suction port 20b on the other end side of the heat exchange element 2B, passes through the second flow path 22b, and from the blowout port 21b on the one end side. By being blown out, it is discharged from the exhaust port 42 on the back surface of the case 11 as exhaust EA through the air supply / exhaust duct 13.

熱交換素子２Ｂでも、第１の流路２２ａを通る外気ＯＡと第２の流路２２ｂを通る室内からの還気ＲＡを対向流とすることで、換気装置１Ｂは、図７に示すような自機が設置される部屋５１の換気に必要な風量を確保しつつ、薄型化が可能である。   Also in the heat exchange element 2B, the ventilation device 1B is configured as shown in FIG. 7 by making the outside air OA passing through the first flow path 22a and the return air RA from the room passing through the second flow path 22b counterflow. It is possible to reduce the thickness while securing the air volume necessary for ventilation of the room 51 where the own machine is installed.

また、空気の吹き出し方向を換気装置１Ｂの側方からとし、空気の吸い込み方向を換気装置１Ｂの上下方向からとすることで、ショートサーキットを抑えることができる。   Moreover, the short circuit can be suppressed by setting the air blowing direction from the side of the ventilator 1B and the air sucking direction from the vertical direction of the ventilator 1B.

第３の実施の形態の換気装置１Ｃは、室内給排部１１ｂの他の実施の形態を示し、熱交換素子２Ｃの他方の端部に風路開閉部材２６を備え、第１の流路２２ａの吹出口２１ａと、第２の流路２２ｂの吸込口２０ｂの向きを切り替えて、給気方向が切り替えられる。   A ventilator 1C according to the third embodiment shows another embodiment of the indoor supply / exhaust part 11b, and includes an air path opening / closing member 26 at the other end of the heat exchange element 2C, and the first flow path 22a. The air supply direction is switched by switching the direction of the air outlet 21a and the suction port 20b of the second flow path 22b.

風路開閉部材２６は、第１の流路２２ａと第２の流路２２ｂにそれぞれ対応して備えられ、図示しない駆動機構により作動する。   The air path opening / closing member 26 is provided corresponding to each of the first flow path 22a and the second flow path 22b, and is operated by a drive mechanism (not shown).

Open and close.

換気装置１Ｃは、室内給排部１１ｂが上下に仕切られており、風路開閉部材２６の動作で、外気給気部１１ｓと還気導入部１１ｒが入れ替わる。これにより、ケース１１の下面の吹出・吸込口を室内給気口３１とし、上面の吹出・吸込口を室内吸込口４２とするか、ケース１１の上面の吹出・吸込口を室内給気口３１とし、下面の吹出・吸込口を室内吸込口４２とするかが切り替えられる。   In the ventilator 1C, the indoor supply / exhaust part 11b is partitioned vertically, and the operation of the air passage opening / closing member 26 exchanges the outside air supply part 11s and the return air introduction part 11r. Accordingly, the blowout / suction port on the lower surface of the case 11 is used as the indoor air supply port 31, and the blowout / suction port on the upper surface is used as the indoor suction port 42, or the blowout / suction port on the upper surface of the case 11 is used as the indoor air supply port 31. And whether the blowout / suction port on the lower surface is the indoor suction port 42 is switched.

＜第３の実施の形態の熱交換型換気装置の動作例＞
次に、各図を参照して第３の実施の形態の換気装置１Ｃの動作について説明する。 <Operation example of the heat exchange type ventilator of the third embodiment>
Next, the operation of the ventilator 1C of the third embodiment will be described with reference to the drawings.

換気装置１Ｃは、風路開閉部材２６を動かすことで、例えば季節に応じて空気の吹き出し方向が切り替えられる。空気の吹き出し方向を下方からとする場合は、図１２（ａ）に示すように、第１の流路２２ａに対向する上部風路形成面２７ａを風路開閉部材２６で塞ぎ、図示されないが、第２の流路２２ｂに対向する下部風路形成面２７ｂを風路開閉部材２６で塞ぐ。   The ventilator 1 </ b> C moves the air path opening / closing member 26 to switch the air blowing direction according to, for example, the season. When the air blowing direction is from below, as shown in FIG. 12 (a), the upper air passage forming surface 27a facing the first flow path 22a is closed by the air passage opening and closing member 26, which is not shown. The lower air passage forming surface 27 b facing the second flow passage 22 b is closed with the air passage opening / closing member 26.

これにより、上部風路形成面２７ａに第２の流路２２ｂの吸込口２０ｂが形成され、下部風路形成面２７ｂに第１の流路２２ａの吹出口２１ａが形成される。   Thereby, the suction inlet 20b of the 2nd flow path 22b is formed in the upper air path formation surface 27a, and the blower outlet 21a of the 1st flow path 22a is formed in the lower air path formation surface 27b.

これに対して、空気の吹き出し方向を上方からとする場合は、図１２（ｂ）に示すように、第２の流路２２ｂに対向する上部風路形成面２７ａを風路開閉部材２６で塞ぎ、図示されないが、第１の流路２２ａに対向する下部風路形成面２７ｂを風路開閉部材２６で塞ぐ。   On the other hand, when the air blowing direction is from above, the upper air passage forming surface 27a facing the second flow path 22b is closed with the air passage opening / closing member 26 as shown in FIG. Although not shown, the lower air passage forming surface 27 b facing the first flow passage 22 a is closed by the air passage opening / closing member 26.

これにより、上部風路形成面２７ａに第１の流路２２ａの吹出口２１ａが形成され、下部風路形成面２７ｂに第２の流路２２ｂの吸込口２０ｂが形成される。   Thereby, the blower outlet 21a of the 1st flow path 22a is formed in the upper air path formation surface 27a, and the suction inlet 20b of the 2nd flow path 22b is formed in the lower air path formation surface 27b.

換気装置１Ｃは、ファンモータ３３ａにより給気ファン３３が回転駆動されると共に、ファンモータ４３ａにより排気ファン４３が回転駆動される。   In the ventilator 1C, the air supply fan 33 is rotationally driven by the fan motor 33a, and the exhaust fan 43 is rotationally driven by the fan motor 43a.

外気導入経路３側では、給気ファン３３が回転駆動されると、ケース１１の背面に形成された外気吸込口３１から外気ＯＡが吸入される。外気吸込口３１から吸入された外気ＯＡは、熱交換素子２Ｃの一方の端部側で吸込口２０ａから第１の流路２２ａに送り込まれ、第１の流路２２ａを通って他方の端部側で吹出口２１ａから吹き出す。   On the outside air introduction path 3 side, when the air supply fan 33 is driven to rotate, outside air OA is sucked from the outside air inlet 31 formed on the back surface of the case 11. The outside air OA sucked from the outside air suction port 31 is sent from the suction port 20a to the first flow path 22a on one end side of the heat exchange element 2C, and passes through the first flow path 22a to the other end. It blows out from the blower outlet 21a by the side.

風路開閉部材２６の動作によって、吹出口２１ａを下部風路形成面２７ｂに形成した場合は、第１の流路２２ａを通る外気ＯＡは、ケース１１の下面の室内給気口３２から、給気ＳＡとして下方へ向けて吹き出される。   When the air outlet 21a is formed in the lower air passage forming surface 27b by the operation of the air passage opening / closing member 26, the outside air OA passing through the first flow path 22a is supplied from the indoor air inlet 32 on the lower surface of the case 11. It is blown out downward as Qi SA.

From the port 32, it blows upward as supply air SA.

内気排出経路４側では、排気ファン４３が回転駆動されると、風路開閉部材２６の動作によって吸込口２０ｂを上部風路形成面２７ａに形成した場合は、ケース１１の上面の室内吸込口４１を通して、ケース１１の上方から室内からの還気ＲＡが吸入される。   On the side of the inside air discharge path 4, when the exhaust fan 43 is driven to rotate, when the air inlet 20 b is formed in the upper air path forming surface 27 a by the operation of the air path opening / closing member 26, the indoor air inlet 41 on the upper surface of the case 11. The return air RA from the room is sucked in from above the case 11.

また、風路開閉部材２６の動作によって吸込口２０ｂを下部風路形成面２７ｂに形成した場合は、ケース１１の下面の室内吸込口４１を通して、ケース１１の下方から室内からの還気ＲＡが吸入される。   Further, when the suction port 20b is formed in the lower air passage forming surface 27b by the operation of the air passage opening / closing member 26, the return air RA from the room is sucked from below the case 11 through the indoor suction port 41 on the lower surface of the case 11.

室内吸込口４１から吸入された還気ＲＡは、熱交換素子２Ｃの他方の端部側で吸込口２０ｂから第２の流路２２ｂに吸い込まれ、第２の流路２２ｂを通って一方の端部側で吹出口２１ｂから吹き出すことで、ケース１１の背面の排気口４２から、給排気ダクト１３を介して排気ＥＡとして排出される。   The return air RA sucked from the indoor suction port 41 is sucked into the second flow path 22b from the suction port 20b on the other end side of the heat exchange element 2C, and passes through the second flow path 22b to one end. By blowing out from the blower outlet 21b on the part side, it is discharged from the exhaust port 42 on the back surface of the case 11 as exhaust EA through the air supply / exhaust duct 13.

熱交換素子２Ｃでも、第１の流路２２ａを通る外気ＯＡと第２の流路２２ｂを通る室内からの還気ＲＡを対向流とすることで、換気装置１Ｃは、図７に示すような自機が設置される部屋５１の換気に必要な風量を確保しつつ、薄型化が可能である。   Even in the heat exchange element 2C, the outside air OA passing through the first flow path 22a and the return air RA from the room passing through the second flow path 22b are opposed to each other, so that the ventilator 1C is configured as shown in FIG. It is possible to reduce the thickness while securing the air volume necessary for ventilation of the room 51 where the own machine is installed.

また、空気の吹き出し方向を、例えば夏季と冬季で切り替えることができる。   Also, the air blowing direction can be switched between, for example, summer and winter.

＜第５の実施の形態の熱交換型換気装置の動作例＞
次に、各図を参照して第５の実施の形態の換気装置１Ｅの動作について説明する。 <Operation example of heat exchange type ventilator according to fifth embodiment>
Next, the operation of the ventilator 1E according to the fifth embodiment will be described with reference to the drawings.

換気装置１Ｅは、給気ファン３３と排気ファン４３が回転駆動される。外気導入経路３側では、給気ファン３３が回転駆動されると、外気吸込口３１から外気ＯＡが吸入される。外気吸込口３１から吸入された外気ＯＡは、熱交換素子２Ｅの一方の端部側で吸込口２０ａから第１の流路２２ａに送り込まれ、第１の流路２２ａを通って他方の端部側で吹出口２１ａから吹き出す。   In the ventilation device 1E, the air supply fan 33 and the exhaust fan 43 are rotationally driven. On the outside air introduction path 3 side, when the air supply fan 33 is driven to rotate, outside air OA is sucked from the outside air inlet 31. The outside air OA sucked from the outside air inlet 31 is sent from the inlet 20a to the first channel 22a on one end side of the heat exchange element 2E, and passes through the first channel 22a to the other end. It blows out from the blower outlet 21a by the side.

吹出口２１ａから吹き出した外気ＯＡは、熱交換素子２Ｅの他方の端部側で折り返され、吸込口２０ｃから第３の流路２２ｃに送り込まれ、第３の流路２２ｃを通って一方の端部側において吹出口２１ｃから吹き出す。   The outside air OA blown out from the air outlet 21a is folded back on the other end side of the heat exchange element 2E, sent to the third flow path 22c from the suction port 20c, and passed through the third flow path 22c to one end. It blows out from the blower outlet 21c in the part side.

熱交換素子２Ｅの吹出口２１ｃから吹き出した外気ＯＡは、室内給気口３２から、給気ＳＡとして例えば前方へ向けて吹き出される。   The outside air OA blown out from the air outlet 21c of the heat exchange element 2E is blown out, for example, forward from the indoor air inlet 32 as the air supply SA.

内気排出経路４及び還気循環経路５側では、排気ファン４３が回転駆動されると、室内吸込口４１を通して例えば側方から室内からの還気ＲＡが吸入される。   On the side of the inside air discharge path 4 and the return air circulation path 5, when the exhaust fan 43 is driven to rotate, the return air RA from the room is sucked from the side, for example, through the indoor suction port 41.

室内吸込口４１から吸入された還気ＲＡの一部は、熱交換素子２Ｅの他方の端部側で吸込口２０ｂから第２の流路２２ｂに吸い込まれ、第２の流路２２ｂを通って一方の端部側で吹出口２１ｂから吹き出すことで、排気口４２から排気ＥＡとして排出される。   A part of the return air RA sucked from the indoor suction port 41 is sucked into the second channel 22b from the suction port 20b on the other end side of the heat exchange element 2E, and passes through the second channel 22b. By being blown out from the air outlet 21b on one end side, the air is exhausted from the exhaust port 42 as exhaust EA.

室内吸込口４１から吸入された還気ＲＡの残部は、熱交換素子２Ｅの他方の端部側で吸込口２０ｄから第４の流路２２ｄに吸い込まれ、第４の流路２２ｄを通って一方の端部側で吹出口２１ｄから吹き出すことで、第３の流路２２ｃの吹出口２１ｃから吹き出した外気ＯＡと混合されて、室内給気口３２から、給気ＳＡとして例えば前方へ向けて吹き出される。   The remaining portion of the return air RA sucked from the indoor suction port 41 is sucked from the suction port 20d into the fourth flow path 22d on the other end side of the heat exchange element 2E, and passes through the fourth flow path 22d. The air is blown out from the air outlet 21d on the end side of the air, so that it is mixed with the outside air OA blown out from the air outlet 21c of the third flow path 22c, and blown out from the indoor air inlet 32, for example, forward as the air supply SA. Is done.

熱交換素子２Ｅでも、第１の流路２２ａを通る外気ＯＡと第２の流路２２ｂを通る室内からの還気ＲＡを対向流とすることで、換気装置１Ｅは、図７に示すような自機が設置される部屋５１の換気に必要な風量を確保しつつ、薄型化が可能である。   Also in the heat exchange element 2E, the outside air OA passing through the first flow path 22a and the return air RA from the room passing through the second flow path 22b are made to counter flow, so that the ventilator 1E is as shown in FIG. It is possible to reduce the thickness while securing the air volume necessary for ventilation of the room 51 where the own machine is installed.

また、空気調和されている室内の空気の一部を循環させることで、換気に伴う室温の上昇や低下を抑えることができる。   Further, by circulating a part of indoor air that is air-conditioned, an increase or decrease in room temperature due to ventilation can be suppressed.

FIG. 16A is a cross-sectional view showing the outline of the first flow path 22a, and FIG. 16B is a cross-sectional view showing the outline of the second flow path 22b.

ここで、以下の説明では、第１の実施の形態の換気装置１Ａと同等の構成の部品については、同じ番号を付して詳細な説明は省略する。   Here, in the following description, the same number is attached | subjected about the component of the structure equivalent to 1 A of ventilation apparatuses of 1st Embodiment, and detailed description is abbreviate | omitted.

第６の実施の形態の換気装置１Ｆは、室内給排部１１ｂの他の実施の形態を示し、熱交換素子２Ｆの正面に室内給気口３２を備えたものである。   A ventilator 1F of the sixth embodiment shows another embodiment of the indoor supply / exhaust unit 11b, and includes an indoor air supply port 32 in front of the heat exchange element 2F.

熱交換素子２Ｆは、空気の流れを対向流とした第１の流路２２ａと第２の流路２２ｂを備え、本例では、第２の流路２２ｂの間に隔壁２４を介して第１の流路２２ａを挟んで構成される例えば３層構造で、第１の流路２２ａと連通する吹出口２１ａを、他方の端部側の正面に備えると共に、第２の流路２２ｂと連通する吸込口２０ｂを、他方の端部側の側面に備える。   The heat exchange element 2F includes a first flow path 22a and a second flow path 22b in which the air flow is a counter flow. In this example, the first flow path 22b is interposed between the first flow path 22b and the first flow path 22b. For example, it has a three-layer structure configured to sandwich the flow path 22a, and a blower outlet 21a communicating with the first flow path 22a is provided on the front surface on the other end side, and is communicated with the second flow path 22b. The suction port 20b is provided on the side surface on the other end side.

吸込口２０ｂは、熱交換素子２Ｆの他方の端部で第２の流路２２ｂと対向する部位を開口して形成される。   The suction port 20b is formed by opening a portion facing the second flow path 22b at the other end of the heat exchange element 2F.

吹出口２１ａは、熱交換素子２Ｆの正面の一部を開口し、第１の流路２２ａに対して正面側に位置する第２の流路２２ｂを貫通して形成される。   The blower outlet 21a is formed by opening a part of the front surface of the heat exchange element 2F and penetrating the second flow path 22b located on the front side with respect to the first flow path 22a.

室内給気口３２は、吹出口２１ａと連通して熱交換素子２Ｆの正面に形成され、第１の流路２２ａと連通している。ここで、室内給気口３２による流路が、第２の流路２２ｂとは隔絶されて、正面側の第２の流路２２ｂ内を横切っており、第１の流路２２ａに対して正面側に位置する第２の流路２２ｂは、室内給気口３２を迂回して吸込口２０ｂと繋がっている。   The indoor air supply port 32 communicates with the air outlet 21a, is formed in front of the heat exchange element 2F, and communicates with the first flow path 22a. Here, the flow path by the indoor air supply port 32 is isolated from the second flow path 22b and crosses the inside of the second flow path 22b on the front side, and is in front of the first flow path 22a. The second flow path 22b located on the side bypasses the indoor air supply port 32 and is connected to the suction port 20b.

熱交換素子２Ｆは、第１の流路２２ａを塞ぐ風路封止部材２９ａを、他方の端部側の側面に備える。風路封止部材２９ａは、熱交換素子２Ｆの他方の端部で第１の流路２２ａと対向する部位を塞ぎ、第１の流路２２ａに対しては、熱交換素子２Ｆの正面側の吹出口２１ａから空気が吹き出されるようになっている。   The heat exchange element 2F includes an air path sealing member 29a that closes the first flow path 22a on the side surface on the other end side. The air path sealing member 29a closes a portion facing the first flow path 22a at the other end of the heat exchange element 2F, and the first flow path 22a is located on the front side of the heat exchange element 2F. Air is blown out from the air outlet 21a.

なお、熱交換素子２Ｆの一方の端部側は、図２（ｂ）に示す構造と同様に、第１の流路２２ａの吸込口２０ａと、第２の流路２２ｂの吹出口２１ｂが上下方向に分かれて構成される。   Note that, on the one end side of the heat exchange element 2F, similarly to the structure shown in FIG. 2B, the suction port 20a of the first flow path 22a and the air outlet 21b of the second flow path 22b are vertically moved. Divided into directions.

＜第６の実施の形態の熱交換型換気装置の動作例＞
次に、各図を参照して第６の実施の形態の換気装置１Ｆの動作について説明する。 <Operation Example of Heat Exchanger Ventilator of Sixth Embodiment>
Next, the operation of the ventilation device 1F according to the sixth embodiment will be described with reference to the drawings.

換気装置１Ｆは、ファンモータ３３ａにより給気ファン３３が回転駆動されると共に、ファンモータ４３ａにより排気ファン４３が回転駆動される。   In the ventilation device 1F, the air supply fan 33 is rotationally driven by the fan motor 33a, and the exhaust fan 43 is rotationally driven by the fan motor 43a.

外気導入経路３側では、給気ファン３３が回転駆動されると、ケース１１の背面に形成された外気吸込口３１から外気ＯＡが吸入される。外気吸込口３１から吸入された外気ＯＡは、熱交換素子２Ｆの一方の端部側で吸込口２０ａから第１の流路２２ａに送り込まれ、第１の流路２２ａを通る。第１の流路２２ａを通る外気ＯＡは、第１の流路２２ａの他方の端部側が風路封止部材２９ａで封止されていることで風向が変わり、室内給気口３２から給気ＳＡとして前方へ向けて吹き出される。   On the outside air introduction path 3 side, when the air supply fan 33 is driven to rotate, outside air OA is sucked from the outside air inlet 31 formed on the back surface of the case 11. The outside air OA sucked from the outside air inlet 31 is sent from the inlet 20a to the first channel 22a on one end side of the heat exchange element 2F, and passes through the first channel 22a. The outside air OA passing through the first flow path 22a is changed in air direction by the other end side of the first flow path 22a being sealed with the air path sealing member 29a, and is supplied from the indoor air supply port 32. It is blown out forward as SA.

内気排出経路４側では、排気ファン４３が回転駆動されると、ケース１１の側面の室内吸込口４１を通して、側方から室内からの還気ＲＡが吸入される。室内吸込口４１から吸入された還気ＲＡは、熱交換素子２Ｆの他方の端部側で吸込口２０ｂから第２の流路２２ｂに吸い込まれ、第２の流路２２ｂを通って一方の端部側で吹出口２１ｂから吹き出すことで、ケース１１の背面の排気口４２から、給排気ダクト１３を介して排気ＥＡとして排出される。ここで、第１の流路２２ａに対して正面側に位置する第２の流路２２ｂでは、還気ＲＡは、室内給気口３２を迂回して吸入される。   On the side of the inside air discharge path 4, when the exhaust fan 43 is rotationally driven, the return air RA from the room is sucked from the side through the room air inlet 41 on the side surface of the case 11. The return air RA sucked from the indoor suction port 41 is sucked into the second flow path 22b from the suction port 20b on the other end side of the heat exchange element 2F, and passes through the second flow path 22b to one end. By blowing out from the blower outlet 21b on the part side, it is discharged from the exhaust port 42 on the back surface of the case 11 as exhaust EA through the air supply / exhaust duct 13. Here, in the second flow path 22b located on the front side with respect to the first flow path 22a, the return air RA is sucked in by bypassing the indoor air supply port 32.

熱交換素子２Ｆでも、第１の流路２２ａを通る外気ＯＡと第２の流路２２ｂを通る室内からの還気ＲＡを対向流とすることで、換気装置１Ｆは、図７に示すような自機が設置される部屋５１の換気に必要な風量を確保しつつ、薄型化が可能である。   Even in the heat exchange element 2F, the ventilator 1F has an external flow OA that passes through the first flow path 22a and a return air RA from the room that passes through the second flow path 22b as counterflows. It is possible to reduce the thickness while securing the air volume necessary for ventilation of the room 51 where the own machine is installed.

また、給気ＳＡの吹出方向を換気装置１Ｆの正面からとし、還気ＲＡの吸入方向を換気装置１Ｆの側方からとすることで、ショートサーキットを抑えることができる。   Moreover, the short circuit can be suppressed by setting the blowing direction of the supply air SA from the front of the ventilator 1F and the intake direction of the return air RA from the side of the ventilator 1F.

なお、本例では、還気ＲＡの吸入方向を換気装置１Ｆの側方からとしたが、上方や下方からとしても良い。   In this example, the intake direction of the return air RA is from the side of the ventilator 1F, but it may be from above or below.

図１７は、熱交換素子２Ｆの変形例を示す断面図で、第６の実施の形態の換気装置１Ｆの変形例について説明する。図１５及び図１６で説明したように、第６の実施の形態の換気装置１Ｆでは、第１の流路２２ａに対して正面側に位置する第２の流路２２ｂは、室内給気口３２を迂回して吸込口２０ｂと繋がっている。   FIG. 17 is a cross-sectional view showing a modification of the heat exchange element 2F, and a modification of the ventilation device 1F of the sixth embodiment will be described. As described with reference to FIGS. 15 and 16, in the ventilation device 1F of the sixth embodiment, the second flow path 22b located on the front side with respect to the first flow path 22a has the indoor air inlet 32. And is connected to the suction port 20b.

このため、還気ＲＡの流入を妨げないようにするため、図１７（ａ）に示すように、室内給気口３２を、還気ＲＡの流入方向に沿って横長の楕円形状とすると良い。また、図１７（ｂ）に示すように、室内給気口３２を、還気ＲＡの流入方向に沿って水滴型形状としても良い。   For this reason, in order not to prevent the inflow of the return air RA, as shown in FIG. 17A, it is preferable that the indoor air supply port 32 has a horizontally long elliptical shape along the inflow direction of the return air RA. Moreover, as shown in FIG.17 (b), it is good also considering the indoor air supply port 32 as a water drop shape along the inflow direction of return air RA.

第７の実施の形態の換気装置１Ｇは、室内給排部１１ｂの他の実施の形態を示し、熱交換素子２Ｇの正面に室内吸込口４１を備えたものである。   A ventilator 1G of the seventh embodiment shows another embodiment of the indoor supply / exhaust section 11b, and includes an indoor suction port 41 in front of the heat exchange element 2G.

熱交換素子２Ｇは、空気の流れを対向流とした第１の流路２２ａと第２の流路２２ｂを備え、本例では、第２の流路２２ｂの間に隔壁２４を介して第１の流路２２ａを挟んで構成される例えば３層構造で、第１の流路２２ａと連通する吹出口２１ａを、他方の端部側の側面に備えると共に、第２の流路２２ｂと連通する吸込口２０ｂを、他方の端部側の正面に備える。   The heat exchange element 2G includes a first flow path 22a and a second flow path 22b in which the air flow is a counter flow. In this example, the first flow path 22b is interposed between the first flow path 22b and the first flow path 22b. For example, it has a three-layer structure configured with the flow path 22a interposed therebetween, and has an air outlet 21a communicating with the first flow path 22a on the side surface on the other end side, and also communicates with the second flow path 22b. The suction port 20b is provided in the front of the other end side.

吹出口２１ａは、熱交換素子２Ｇの他方の端部で第１の流路２２ａと対向する部位を開口して形成される。   The blower outlet 21a is formed by opening a portion facing the first flow path 22a at the other end of the heat exchange element 2G.

吸込口２０ｂは、熱交換素子２Ｇの正面の一部を開口し、第１の流路２２ａを貫通して形成される。   The suction port 20b is formed by opening a part of the front surface of the heat exchange element 2G and penetrating the first flow path 22a.

室内吸込口４１は、吸込口２０ｂと連通して熱交換素子２Ｇの正面に形成され、第１の流路２２ａに対して正面側に位置する第２の流路２２ｂと、背面側に位置する第２の流路２２ｂの双方と連通している。ここで、室内吸込口４１による流路が、第１の流路２２ａとは隔絶されて、第１の流路２２ａ内を横切っており、第１の流路２２ａは、室内吸込口４１を迂回して吹出口２１ａと繋がっている。   The indoor suction port 41 communicates with the suction port 20b and is formed on the front surface of the heat exchange element 2G. The indoor suction port 41 is positioned on the rear surface side with the second flow channel 22b positioned on the front side with respect to the first flow channel 22a. It communicates with both of the second flow paths 22b. Here, the flow path by the indoor suction port 41 is isolated from the first flow path 22a and crosses the inside of the first flow path 22a, and the first flow path 22a bypasses the indoor suction port 41. And it is connected with the blower outlet 21a.

熱交換素子２Ｇは、第２の流路２２ｂを塞ぐ風路封止部材２９ｂを、他方の端部側の側面に備える。風路封止部材２９ｂは、熱交換素子２Ｇの他方の端部で第２の流路２２ｂと対向する部位を塞ぎ、第２の流路２２ｂに対しては、熱交換素子２Ｇの正面側の吸込口２０ｂから空気が吸い込まれるようになっている。   The heat exchange element 2G includes an air path sealing member 29b that closes the second flow path 22b on the side surface on the other end side. The air path sealing member 29b closes a portion facing the second flow path 22b at the other end of the heat exchange element 2G, and the second flow path 22b is located on the front side of the heat exchange element 2G. Air is sucked from the suction port 20b.

なお、熱交換素子２Ｇの一方の端部側は、図２（ｂ）に示す構造と同様に、第１の流路２２ａの吸込口２０ａと、第２の流路２２ｂの吹出口２１ｂが上下方向に分かれて構成される。   Note that, on the one end side of the heat exchange element 2G, similarly to the structure shown in FIG. 2B, the suction port 20a of the first flow path 22a and the air outlet 21b of the second flow path 22b are vertically moved. Divided into directions.

＜第７の実施の形態の熱交換型換気装置の動作例＞
次に、各図を参照して第７の実施の形態の換気装置１Ｇの動作について説明する。 <Operation Example of Heat Exchanger Ventilator of Seventh Embodiment>
Next, the operation of the ventilation device 1G according to the seventh embodiment will be described with reference to the drawings.

換気装置１Ｇは、ファンモータ３３ａにより給気ファン３３が回転駆動されると共に、ファンモータ４３ａにより排気ファン４３が回転駆動される。   In the ventilation device 1G, the air supply fan 33 is rotationally driven by the fan motor 33a, and the exhaust fan 43 is rotationally driven by the fan motor 43a.

外気導入経路３側では、給気ファン３３が回転駆動されると、ケース１１の背面に形成された外気吸込口３１から外気ＯＡが吸入される。外気吸込口３１から吸入された外気ＯＡは、熱交換素子２Ｇの一方の端部側で吸込口２０ａから第１の流路２２ａに送り込まれ、第１の流路２２ａを通る。第１の流路２２ａを通る外気ＯＡは、第１の流路２２ａの他方の端部側で吹出口２１ａから吹き出し、室内給気口３２から給気ＳＡとして側方へ向けて吹き出される。ここで、第１の流路２２ａでは、外気ＯＡは室内吸込口４１を迂回して給気される。   On the outside air introduction path 3 side, when the air supply fan 33 is driven to rotate, outside air OA is sucked from the outside air inlet 31 formed on the back surface of the case 11. The outside air OA sucked from the outside air inlet 31 is sent to the first channel 22a from the inlet 20a on one end side of the heat exchange element 2G, and passes through the first channel 22a. The outside air OA passing through the first flow path 22a is blown out from the air outlet 21a on the other end side of the first flow path 22a, and blown out sideways as the air supply SA from the indoor air supply port 32. Here, in the first flow path 22a, the outside air OA is supplied by bypassing the indoor suction port 41.

内気排出経路４側では、排気ファン４３が回転駆動されると、ケース１１の正面の室内吸込口４１を通して、前方から室内からの還気ＲＡが吸入される。室内吸込口４１から吸入された還気ＲＡは、熱交換素子２Ｇの他方の端部側で正面の吸込口２０ｂから第２の流路２２ｂに吸い込まれ、第２の流路２２ｂを通って一方の端部側で吹出口２１ｂから吹き出すことで、ケース１１の背面の排気口４２から、給排気ダクト１３を介して排気ＥＡとして排出される。   On the inside air discharge path 4 side, when the exhaust fan 43 is driven to rotate, the return air RA from the room is sucked from the front through the room air inlet 41 in front of the case 11. The return air RA sucked from the indoor suction port 41 is sucked into the second flow path 22b from the front suction port 20b on the other end side of the heat exchange element 2G, and passes through the second flow path 22b. By being blown out from the blowout port 21b on the end side, the exhaust gas is discharged from the exhaust port 42 on the back surface of the case 11 through the air supply / exhaust duct 13 as exhaust EA.

熱交換素子２Ｇでも、第１の流路２２ａを通る外気ＯＡと第２の流路２２ｂを通る室内からの還気ＲＡを対向流とすることで、換気装置１Ｇは、図７に示すような自機が設置される部屋５１の換気に必要な風量を確保しつつ、薄型化が可能である。   Even in the heat exchange element 2G, the ventilation device 1G is configured as shown in FIG. 7 by making the outside air OA passing through the first flow path 22a and the return air RA from the room passing through the second flow path 22b counterflow. It is possible to reduce the thickness while securing the air volume necessary for ventilation of the room 51 where the own machine is installed.

また、給気ＳＡの吹出方向を換気装置１Ｇの側方からとし、還気ＲＡの吸入方向を換気装置１Ｇの正面からとすることで、ショートサーキットを抑えることができると共に、換気装置１Ｇの前方に居る人に対して、風が直接当たることを抑えることができる。   Further, by setting the blowing direction of the supply air SA from the side of the ventilator 1G and the intake direction of the return air RA from the front of the ventilator 1G, a short circuit can be suppressed and the front side of the ventilator 1G can be suppressed. It is possible to prevent the wind from directly hitting those who are in the area.

なお、本例では、給気ＳＡの吹出方向を換気装置１Ｇの側方からとしたが、上方や下方からとしても良い。   In addition, in this example, although the blowing direction of supply air SA was made from the side of the ventilation apparatus 1G, it is good also from upper direction or the downward direction.

図２０は、熱交換素子２Ｇの変形例を示す断面図で、第７の実施の形態の換気装置１Ｇの変形例について説明する。図１８及び図１９で説明したように、第７の実施の形態の換気装置１Ｇでは、第１の流路２２ａは、室内吸込口４１を迂回して吹出口２１ａと繋がっている。   FIG. 20 is a cross-sectional view showing a modification of the heat exchange element 2G, and a modification of the ventilation device 1G of the seventh embodiment will be described. As described with reference to FIGS. 18 and 19, in the ventilation device 1G of the seventh embodiment, the first flow path 22a bypasses the indoor suction port 41 and is connected to the air outlet 21a.

このため、外気ＯＡの流入を妨げないようにするため、図２０（ａ）に示すように、室内吸込口４１を、外気ＯＡの流入方向に沿って横長の楕円形状とすると良い。また、図２０（ｂ）に示すように、室内吸込口４１を、外気ＯＡの流入方向に沿って水滴型形状としても良い。   For this reason, in order not to prevent the inflow of the outside air OA, as shown in FIG. 20A, it is preferable that the indoor suction port 41 has a horizontally long elliptical shape along the inflow direction of the outside air OA. Moreover, as shown in FIG.20 (b), it is good also considering the indoor suction inlet 41 as a water drop shape along the inflow direction of external air OA.

By blowing out from the blower outlet 21b on the part side, it is discharged from the exhaust port 42 on the back surface of the case 11 as exhaust EA through the air supply / exhaust duct 13.

熱交換素子２Ｈでも、第１の流路２２ａを通る外気ＯＡと第２の流路２２ｂを通る室内からの還気ＲＡを対向流とすることで、換気装置１Ｈは、図７に示すような自機が設置される部屋５１の換気に必要な風量を確保しつつ、薄型化が可能である。   Even in the heat exchange element 2H, the outside air OA passing through the first flow path 22a and the return air RA from the room passing through the second flow path 22b are made to counter flow, so that the ventilator 1H has a configuration as shown in FIG. It is possible to reduce the thickness while securing the air volume necessary for ventilation of the room 51 where the own machine is installed.

FIG.22 (b) is sectional drawing which shows the principal part structure of the heat exchange element 2J integrated in the ventilator 1J.

ここで、以下の説明では、第１の実施の形態の換気装置１Ａと同等の構成の部品については、同じ番号を付して詳細な説明は省略する。   Here, in the following description, the same number is attached | subjected about the component of the structure equivalent to 1 A of ventilation apparatuses of 1st Embodiment, and detailed description is abbreviate | omitted.

第９の実施の形態の換気装置１Ｊは、外気ＯＡと還気ＲＡの温度や湿度を測定し、熱交換素子２Ｊで結露が生じる可能性がある場合は、熱交換素子２Ｊを加熱して結露の発生を抑えるものである。   The ventilator 1J of the ninth embodiment measures the temperature and humidity of the outside air OA and the return air RA, and if there is a possibility that condensation occurs in the heat exchange element 2J, the heat exchange element 2J is heated to cause condensation. Is to suppress the occurrence of.

換気装置１Ｊは、熱交換前の外気ＯＡが通る外気導入部１１ｏに外気温度センサ７０ａを備える。また、熱交換前の還気ＲＡが通る室内導入部１１ｒに還気温度センサ７０ｂを備える。外気温度センサ７０ａと還気温度センサ７０ｂは、状態検出手段の一例で、外気温度センサ７０ａは、熱交換素子２Ｊの第１の流路２２ａに導入される前の外気ＯＡの温度を測定する。また、還気温度センサ７０ｂは、熱交換素子２Ｊの第２の流路２２ｂに導入される前の還気ＲＡの温度を測定する。   The ventilator 1J includes an outside air temperature sensor 70a in the outside air introduction part 11o through which the outside air OA before heat exchange passes. Moreover, the return air temperature sensor 70b is provided in the indoor introduction part 11r through which the return air RA before heat exchange passes. The outside air temperature sensor 70a and the return air temperature sensor 70b are examples of state detection means, and the outside air temperature sensor 70a measures the temperature of the outside air OA before being introduced into the first flow path 22a of the heat exchange element 2J. The return air temperature sensor 70b measures the temperature of the return air RA before being introduced into the second flow path 22b of the heat exchange element 2J.

熱交換素子２Ｊは、第１の流路２２ａと第２の流路２２ｂが、隔壁２４を挟んで交互に積層される。第１の流路２２ａは、隔壁２４の間が金属素材で構成された流路形成板２４ａによって仕切られて、複数本の平行な流路が直線状に形成される。   In the heat exchange element 2J, the first flow path 22a and the second flow path 22b are alternately stacked with the partition wall 24 interposed therebetween. The first flow path 22a is partitioned between the partition walls 24 by a flow path forming plate 24a made of a metal material, and a plurality of parallel flow paths are linearly formed.

また、第２の流路２２ｂは、隔壁２４の間が金属素材で構成された流路形成板２４ｂによって仕切られて、複数本の平行な流路が、第１の流路２２ａに沿った平行な向きで直線状に形成される。   The second flow path 22b is partitioned between the partition walls 24 by a flow path forming plate 24b made of a metal material, and a plurality of parallel flow paths are parallel to the first flow path 22a. It is formed in a straight line in any direction.

第１の流路２２ａは、流路形成板２４ａの間に面状発熱体７１ａを備える。また、第２の流路２２ｂは、流路形成板２４ｂの間に面状発熱体７１ｂを備える。面状発熱体７１ａ，７１ｂは温度制御手段の一例で、面状発熱体７１ａは、流路形成板２４ａの温度を制御する。また、面状発熱体７１ｂは、流路形成板２４ｂの温度を制御する。   The first flow path 22a includes a planar heating element 71a between the flow path forming plates 24a.

＜第９の実施の形態の熱交換型換気装置の動作例＞
次に、各図を参照して第９の実施の形態の換気装置１Ｊの動作について説明する。 <Operation Example of Heat Exchanger Ventilator of Ninth Embodiment>
Next, with reference to each figure, operation | movement of the ventilation apparatus 1J of 9th Embodiment is demonstrated.

換気装置１Ｊは、ファンモータ３３ａにより給気ファン３３が回転駆動されると共に、ファンモータ４３ａにより排気ファン４３が回転駆動される。   In the ventilator 1J, the air supply fan 33 is rotationally driven by the fan motor 33a, and the exhaust fan 43 is rotationally driven by the fan motor 43a.

外気導入経路３側では、給気ファン３３が回転駆動されると、ケース１１の背面に形成された外気吸込口３１から外気ＯＡが吸入される。外気吸込口３１から吸入された外気ＯＡは、熱交換素子２Ｊの一方の端部側で吸込口２０ａから第１の流路２２ａに送り込まれ、第１の流路２２ａを通る。   On the outside air introduction path 3 side, when the air supply fan 33 is driven to rotate, outside air OA is sucked from the outside air inlet 31 formed on the back surface of the case 11. The outside air OA sucked from the outside air suction port 31 is sent from the suction port 20a to the first flow path 22a on one end side of the heat exchange element 2J, and passes through the first flow path 22a.

第１の流路２２ａを通る外気ＯＡは、熱交換素子２Ｊの他方の端部側において吹出口２１ａから吹き出し、例えばケース１１の正面側の室内給気口３２から、給気ＳＡとして前方へ向けて吹き出される。   The outside air OA passing through the first flow path 22a is blown out from the air outlet 21a on the other end side of the heat exchange element 2J, for example, from the indoor air inlet 32 on the front side of the case 11 toward the front as the air supply SA. And blown out.

内気排出経路４側では、排気ファン４３が回転駆動されると、室内からの還気ＲＡが、ケース１１の側方から室内吸込口４１へと吸入される。室内吸込口４１から吸入された還気ＲＡは、内気排出経路４を通り、熱交換素子２Ａの他方の端部において吸込口２０ｂから吸い込まれる。   On the side of the inside air discharge path 4, when the exhaust fan 43 is rotationally driven, the return air RA from the room is sucked from the side of the case 11 into the room air inlet 41. The return air RA sucked from the indoor suction port 41 passes through the inside air discharge path 4 and is sucked from the suction port 20b at the other end of the heat exchange element 2A.

熱交換素子２Ａの吸込口２０ｂに吸い込まれた還気ＲＡは、第２の流路２２ｂを通り、一方の端部において吹出口２１ｂから吹き出す。熱交換素子２Ｊの吹出口２１ｂから吹き出した還気ＲＡは、ケース１１の背面側の排気口４２から、給排気ダクト１３を介して排気ＥＡとして排出される。   The return air RA sucked into the suction port 20b of the heat exchange element 2A passes through the second flow path 22b and blows out from the blowout port 21b at one end. The return air RA blown out from the air outlet 21b of the heat exchange element 2J is exhausted from the exhaust port 42 on the back side of the case 11 as exhaust EA through the air supply / exhaust duct 13.

さて、空気調和された室内の空気は、夏季は外気より温度が低く、冬季は外気より温度が高い。熱交換素子２Ｊでは、第１の流路２２ａを通る外気ＯＡと第２の流路２２ｂを通る室内からの還気ＲＡの間で熱交換が行われることで、夏季は、温度の高い外気と冷却された室内の空気との間で熱交換が行われ、外気ＯＡの温度が下げられる。また、冬季は、温度の低い外気と暖房された室内の空気との間で熱交換が行われ、外気ＯＡの温度が上げられる。   Now, the air in the air-conditioned room has a lower temperature than the outside air in summer and a higher temperature than the outside air in winter. In the heat exchange element 2J, heat exchange is performed between the outside air OA passing through the first flow path 22a and the return air RA from the room passing through the second flow path 22b. Heat exchange is performed with the cooled indoor air, and the temperature of the outside air OA is lowered. In winter, heat is exchanged between the low temperature outside air and the heated indoor air, and the temperature of the outside air OA is raised.

これにより、換気装置１Ｊでは、外気を室内の温度に近づけて、給気を行いながら室内の換気を行うことができる。   Thereby, in the ventilator 1J, indoor air can be ventilated while supplying external air by bringing the outside air close to the room temperature.

ここで、熱交換前の外気ＯＡは、外気温度センサ７０ａで温度が測定される。また、熱交換前の還気ＲＡは、還気温度センサ７０ｂで温度が測定される。そして、外気温度センサ７０ａで測定した外気ＯＡの温度と、還気温度センサ７０ｂで測定した還気ＲＡの温度が、所定の結露発生温度差以上であることを検出すると、図示しない制御部は、面状発熱体７１ａ及び面状発熱体７１ｂを制御して、流路形成板２４ａと流路形成板２４ｂの何れか、あるいは双方を加熱する。   Here, the temperature of the outside air OA before heat exchange is measured by the outside air temperature sensor 70a. Further, the temperature of the return air RA before heat exchange is measured by the return air temperature sensor 70b. When detecting that the temperature of the outside air OA measured by the outside air temperature sensor 70a and the temperature of the return air RA measured by the return air temperature sensor 70b are equal to or greater than a predetermined dew condensation temperature difference, The sheet heating element 71a and the sheet heating element 71b are controlled to heat either or both of the flow path forming plate 24a and the flow path forming plate 24b.

これにより、流路形成板２４ａと流路形成板２４ｂの温度が上げられて、第１の流路２２ａを通る外気ＯＡと第２の流路２２ｂを通る還気ＲＡとの温度差による結露の発生を抑制することができる。   As a result, the temperatures of the flow path forming plate 24a and the flow path forming plate 24b are raised, and dew condensation due to the temperature difference between the outside air OA passing through the first flow path 22a and the return air RA passing through the second flow path 22b. Occurrence can be suppressed.

このように、熱交換素子２Ｊでも、第１の流路２２ａを通る外気ＯＡと第２の流路２２ｂを通る室内からの還気ＲＡを対向流とすることで、換気装置１Ｊは、図７に示すような自機が設置される部屋５１の換気に必要な風量を確保しつつ、薄型化が可能である。   In this way, also in the heat exchange element 2J, the ventilator 1J is configured so that the outside air OA passing through the first flow path 22a and the return air RA from the room passing through the second flow path 22b are opposed to each other. It is possible to reduce the thickness while securing the air volume necessary for ventilation of the room 51 where the own machine is installed as shown in FIG.

また、換気装置１Ｊは、熱交換素子２Ｊでの結露の発生を抑えることができるので、カビの発生等を抑えることができる。   Moreover, since the ventilator 1J can suppress the occurrence of dew condensation on the heat exchange element 2J, it can suppress the occurrence of mold and the like.

なお、以上の例では、結露が発生する状態か否かを検出する状態検出手段として、温度を測定する温度センサを備えたが、湿度を測定する湿度センサを備えても良い。   In the above example, the temperature sensor for measuring the temperature is provided as the state detection means for detecting whether or not condensation occurs. However, a humidity sensor for measuring the humidity may be provided.

本発明は、住宅の居室等の壁面に設置され、熱交換機能を有する換気装置に適用される。   The present invention is applied to a ventilator that is installed on a wall surface of a residential room or the like and has a heat exchange function.
