Description

本発明は、全熱交換器及びこれを用いた換気システムに係り、より詳細には、構造を改善し熱交換面積を増加させることによって全熱効率を増加させることができる全熱交換器及び換気システムに関する。   The present invention relates to a total heat exchanger and a ventilation system using the total heat exchanger, and more particularly to a total heat exchanger and a ventilation system capable of increasing the total heat efficiency by improving the structure and increasing the heat exchange area. About.

一般に、密閉された室内の空気は、室内で活動する人の呼吸などによって時間が経つにつれ次第に汚染されていく。このため、室内の汚染された空気を室外の新鮮な空気に随時交換しなければならないが、この場合、通常、全熱交換器を用いた換気システムが使用される。   In general, air in a sealed room is gradually polluted over time due to the breathing of a person who is active in the room. For this reason, the contaminated air in the room must be exchanged for fresh air outside the room, but in this case, a ventilation system using a total heat exchanger is usually used.

特に、家庭、大型ビル及び工場建物などには、室内空間を換気するために様々な換気システムが使用される。かかる換気システムは、室外空気を室内に供給するための給気ファン、室内空気を室外に排出するための排気ファン、これら室内空気及び室外空気を室外に導くダクトなどを備えてなる。また、この換気システムは、外部に排出される室内空気に含まれた熱エネルギーの一部を回収するための全熱交換器が設置されることもある。   In particular, various ventilation systems are used to ventilate indoor spaces in homes, large buildings, factory buildings, and the like. Such a ventilation system includes an air supply fan for supplying outdoor air to the room, an exhaust fan for discharging the room air to the outside, a duct for guiding the room air and the outdoor air to the outside, and the like. In addition, this ventilation system may be provided with a total heat exchanger for recovering a part of the heat energy contained in the indoor air discharged to the outside.

しかしながら、上述した従来の全熱交換器は、次のような問題点があった。
第一に、建築設計に当たって天井厚が制限されるため、天井内部に設置される全熱交換器の高さが制限され、また、室内空気と室外空気を熱交換させるために全熱交換器内部に設置される熱交換素子の高さも制限され、結果として、熱交換素子の熱交換面積が小さくなり、全熱交換器の全熱効率が相対的に低くなるという問題点があった。 However, the conventional total heat exchanger described above has the following problems.
First, because the ceiling thickness is limited in building design, the height of the total heat exchanger installed inside the ceiling is limited, and the interior of the total heat exchanger is used to exchange heat between indoor air and outdoor air. As a result, the heat exchange area of the heat exchanger element becomes small, and the total heat efficiency of the total heat exchanger becomes relatively low.

第二に、熱交換素子を通過する空気の流速が高いため、熱交換素子から熱交換が有効に行われず、全熱交換器の効率が低いという問題があった。   Second, since the flow rate of air passing through the heat exchange element is high, heat exchange from the heat exchange element is not performed effectively, and the efficiency of the total heat exchanger is low.

第三に、熱交換素子を通過する室内空気と室外空気の流動方向変化が大きいため、流路抵抗が増加するという問題があった。   Third, there is a problem that the flow resistance increases because the flow direction change between the indoor air and the outdoor air passing through the heat exchange element is large.

本発明は上記の問題点を解決するためのもので、その目的は、全熱効率を増加させることができる全熱交換器及びこれを用いた換気システムを提供することにある。   The present invention is to solve the above-described problems, and an object thereof is to provide a total heat exchanger capable of increasing the total heat efficiency and a ventilation system using the total heat exchanger.

FIG. 3A is a graph schematically showing changes in temperature due to the flow lengths of the indoor air and the outdoor air during the cooling operation for cooling the room, and FIG. 3B shows the indoor air during the heating operation for heating the room. It is a graph which shows roughly the temperature change by the channel length of outdoor air.

図１乃至図３Ｂを参照して、本発明による全熱交換器の第１実施例を説明すると、次の通りである。   A first embodiment of the total heat exchanger according to the present invention will be described with reference to FIGS. 1 to 3B.

全熱交換器１は、室外空気を室内に導く給気ダクト１０、室内空気を室外に導く排気ダクト２０、これら室外空気と室内空気を熱交換させる熱交換素子５０ａを備える。また、全熱交換器１は、室外空気を吸入して室内に排出する給気ファン１３と、室内空気を吸入して室外に排出する排気ファン２３とをさらに備えることができる。   The total heat exchanger 1 includes an air supply duct 10 that guides outdoor air into the room, an exhaust duct 20 that guides indoor air to the outside, and a heat exchange element 50a that exchanges heat between the outdoor air and the room air. The total heat exchanger 1 can further include an air supply fan 13 that sucks outdoor air and discharges it indoors, and an exhaust fan 23 that sucks indoor air and discharges it outdoor.

熱交換素子５０ａは、給気ダクト１０によって導かれる室外空気の流れと排気ダクト２０によって導かれる室内空気の流れとが互いに交差する領域に設置されるもので、これら両空気の温度差を用いた顕熱交換と両空気の湿度差を用いた潜熱交換を通じて室内空気と室外空気を熱交換させる。   The heat exchange element 50a is installed in a region where the flow of outdoor air guided by the air supply duct 10 and the flow of indoor air guided by the exhaust duct 20 intersect each other, and the temperature difference between these two airs is used. Heat is exchanged between indoor air and outdoor air through sensible heat exchange and latent heat exchange using the humidity difference between the two airs.

具体的に、熱交換素子５０ａの内部には、室内空気と室外空気が通過する第１熱交換流路（図示せず）と第２熱交換流路（図示せず）が個別に形成されている。これら第１熱交換流路と第２熱交換流路は、熱的特性に優れた熱交換膜（図示せず）によって区画されている。   Specifically, a first heat exchange channel (not shown) and a second heat exchange channel (not shown) through which room air and outdoor air pass are individually formed inside the heat exchange element 50a. Yes. The first heat exchange channel and the second heat exchange channel are partitioned by a heat exchange membrane (not shown) having excellent thermal characteristics.

したがって、温度及び湿度差を持つ室内空気と室外空気がそれぞれの熱交換流路を通過すると、これら両空気において熱交換膜によって熱交換が発生するようになる。   Therefore, when indoor air and outdoor air having a temperature and humidity difference pass through the respective heat exchange channels, heat exchange occurs between the air and the heat exchange membrane.

一方、熱交換素子５０ａの一側にはフィルタ（図示せず）が設置されても良い。このフィルタは、空気中の異物をろ過する役割を担うもので、全熱交換器とは別に着脱自在に取り付けられる。   On the other hand, a filter (not shown) may be installed on one side of the heat exchange element 50a. This filter plays a role of filtering foreign substances in the air, and is detachably attached separately from the total heat exchanger.

給気ダクト１０の一端には、室外と連通する給気ダクト吸入口１１が形成され、他端には、室内と連通する給気ダクト排出口１２が形成される。また、排気ダクト２０の一端には、室内と連通する排気ダクト吸入口２１が形成され、他端には、室外と連通する排気ダクト排出口２２が形成される。   At one end of the air supply duct 10, an air supply duct suction port 11 communicating with the outside is formed, and at the other end, an air supply duct discharge port 12 communicating with the room is formed. Further, an exhaust duct suction port 21 communicating with the room is formed at one end of the exhaust duct 20, and an exhaust duct discharge port 22 communicating with the outside is formed at the other end.

また、給気ダクト１０上には、室外から室外空気を強制吸入して室内に供給する給気ファン１３が備えられ、排気ダクト２０上には、室内の汚染空気を強制に吸入して室外に排出する排気ファン２３が備えられる。   An air supply fan 13 is provided on the air supply duct 10 to forcibly suck outdoor air from the outside and supply it indoors. On the exhaust duct 20, the indoor air is forcibly sucked to the outside. An exhaust fan 23 for discharging is provided.

給気ファン１３と排気ファン２３は、それぞれの給気ファンハウジングと排気ファンハウジングの内部に配置される。また、給気ファンハウジング及び排気ファンハウジングの前方側には当該ファンを駆動させるモーター（図示せず）が装着される。   The supply fan 13 and the exhaust fan 23 are disposed inside the supply fan housing and the exhaust fan housing, respectively. Further, a motor (not shown) for driving the fan is mounted on the front side of the air supply fan housing and the exhaust fan housing.

以下、上記のように構成された換気システムの作用について説明する。   Hereinafter, the operation of the ventilation system configured as described above will be described.

まず、室内空気がある程度汚染された時に、排気ファン２３に電源が印加されると、室内空気が排気ダクト吸入口２１から排気ダクト２０に流入し、排気ダクト２０を経由した室内空気は、熱交換素子５０ａを対角線方向に通過する。   First, when power is applied to the exhaust fan 23 when the room air is contaminated to some extent, the room air flows into the exhaust duct 20 from the exhaust duct inlet 21, and the indoor air passing through the exhaust duct 20 exchanges heat. It passes through the element 50a in the diagonal direction.

続いて、熱交換素子５０ａを通過した室内空気は、排気ダクト２０に沿って流動し、排気ダクト排出口２２から室外に排出される。これと同時に、室外空気が給気ダクト流入口１１から給気ダクト１０に流入した後、熱交換素子５０ａを対角線方向に通過する。   Subsequently, the room air that has passed through the heat exchange element 50 a flows along the exhaust duct 20 and is discharged to the outside from the exhaust duct outlet 22. At the same time, after outdoor air flows into the air supply duct 10 from the air supply duct inlet 11, it passes through the heat exchange element 50a in a diagonal direction.

続いて、熱交換素子５０ａを通過した室外空気は、給気ダクトに沿って流動し、給気ダクト排出口１２から室内に供給される。このような過程によって熱交換素子５０ａを通過する室内空気と室外空気は相互に熱交換され、これにより、室内に適切な温度の室外空気が供給されるようになる。   Subsequently, the outdoor air that has passed through the heat exchange element 50a flows along the air supply duct and is supplied into the room from the air supply duct discharge port 12. Through such a process, the indoor air and the outdoor air passing through the heat exchange element 50a are mutually heat-exchanged, whereby outdoor air having an appropriate temperature is supplied into the room.

一方、室内空気は、大きく、２つの経路のうち一つを通じて外部に排気される。一番目の経路に対しては、排気ダクト吸入口２１から流入する空気が、排気ダクト第１流入穴２４を経て給気ダクト吸入口１１からの室外空気と熱交換素子５０ａを通過しつつ熱交換されてから外部に排出される。また、２番目の経路に対しては、排気ダクト吸入口２１から流入する室内空気は、熱交換素子５０ａを通過せずに排気ファン２３の強制吸引力によって直接室外に排出される。   On the other hand, room air is largely exhausted to the outside through one of two paths. For the first path, the air flowing from the exhaust duct inlet 21 passes through the exhaust duct first inlet hole 24 and exchanges heat with the outdoor air from the supply duct inlet 11 through the heat exchange element 50a. And then discharged to the outside. For the second path, the indoor air flowing from the exhaust duct suction port 21 is directly discharged to the outside by the forced suction force of the exhaust fan 23 without passing through the heat exchange element 50a.

後者の場合、全熱交換器１は、室内空気を直接排気ダクト排出口２２に流れるようにする排気用バイパス流路２６をさらに備える。したがって、排気ダクト流入口２１から流入した室内空気は、排気ダクト第２流入穴２５を通ってバイパス流路２６を経由して外部に排出される。また、排気ダクト流入口２１には、室内空気をバイパス流路に導くためのダンパーが備えられても良い。   In the latter case, the total heat exchanger 1 further includes an exhaust bypass passage 26 that allows indoor air to flow directly to the exhaust duct outlet 22. Accordingly, the room air flowing in from the exhaust duct inlet 21 passes through the exhaust duct second inflow hole 25 and is discharged to the outside via the bypass channel 26. Further, the exhaust duct inlet 21 may be provided with a damper for guiding the indoor air to the bypass flow path.

このように構成すると、春や秋のように室内空気と室外空気との温度及び湿度差が小さい場合には、室内空気と室外空気が熱交換素子を経由しないようにすることによって熱交換素子による圧力損失を低減可能になる。その結果、ファンにかかる負荷減少によって消費電力を低減し、エネルギーの節約が図られる。   With this configuration, when the temperature and humidity difference between the indoor air and the outdoor air is small as in spring or autumn, the indoor air and the outdoor air are prevented from passing through the heat exchange element. Pressure loss can be reduced. As a result, power consumption is reduced by reducing the load on the fan, and energy can be saved.

一方、全熱交換器の全熱効率は、熱交換素子５０ａにおける室内空気と室外空気との熱交換効率に左右され、したがって、所定の全熱効率を得るためには、熱交換素子５０ａの断面積を増加させなければならない。にもかかわらず、建築設計上の制約のために熱交換素子５０ａの垂直方向の長さ、すなわち熱交換素子の断面高さを増加させるには制限がある。   On the other hand, the total heat efficiency of the total heat exchanger depends on the heat exchange efficiency between the indoor air and the outdoor air in the heat exchange element 50a. Therefore, in order to obtain a predetermined total heat efficiency, the cross-sectional area of the heat exchange element 50a is set. Must be increased. Nevertheless, there is a limitation in increasing the vertical length of the heat exchange element 50a, that is, the cross-sectional height of the heat exchange element, due to architectural design constraints.

このように全熱効率の向上と熱交換素子５０ａの断面高さの最小化は互いに相反する関係にある。そこで、本発明者は、全熱交換器の全熱効率を高める上で、熱交換素子５０ａの断面高さを増加させることなく熱交換素子の断面積を増加させる方法を見出し、本発明を完成するに至った。   Thus, the improvement of the total heat efficiency and the minimization of the cross-sectional height of the heat exchange element 50a are in a mutually contradictory relationship. Therefore, the present inventors have found a method for increasing the cross-sectional area of the heat exchange element without increasing the cross-sectional height of the heat exchange element 50a in order to increase the total heat efficiency of the total heat exchanger, and complete the present invention. It came to.

具体的に、熱交換素子の形状は、該熱交換素子を経由する室外空気の流れと室内空気の流れとが互いに鋭角θをなすようにする。また、熱交換素子は、熱交換素子の断面高さｈよりも熱交換素子の断面幅ｗが大きい形状を有し、本実施例では、図２に示すように、熱交換素子の形状を菱形としている。   Specifically, the shape of the heat exchange element is such that the outdoor air flow and the indoor air flow passing through the heat exchange element form an acute angle θ with each other. The heat exchange element has a shape in which the cross-sectional width w of the heat exchange element is larger than the cross-sectional height h of the heat exchange element. In this embodiment, as shown in FIG. It is said.

ここで、熱交換素子の断面形状は、いずれの形態であっても良く、例えば、曲線形態の断面形状または多角形の断面形状にしても良く、直線部と曲線部が混合された断面形状にしても良い。   Here, the cross-sectional shape of the heat exchange element may be any form. For example, the cross-sectional shape may be a curved cross-sectional shape or a polygonal cross-sectional shape. May be.

熱交換素子の断面幅が断面高さよりも大きい値を有すると、熱交換素子５０ａを流動する空気の流路長さが増加し、流動する空気の流速は減少する。したがって、熱交換素子５０ａを通過する室内空気と室外空気はより效率的に熱交換可能になる。   When the cross-sectional width of the heat exchange element has a value larger than the cross-sectional height, the flow path length of the air flowing through the heat exchange element 50a increases, and the flow velocity of the flowing air decreases. Therefore, the indoor air and the outdoor air passing through the heat exchange element 50a can exchange heat more efficiently.

なお、熱交換素子の断面幅が断面高さよりも大きい値を有すると、給気ダクトと排気ダクトを流れる空気の流動方向の変化が減少し、流路抵抗が低減するさらなる効果がある。   In addition, when the cross-sectional width of the heat exchange element has a value larger than the cross-sectional height, a change in the flow direction of the air flowing through the air supply duct and the exhaust duct is reduced, and there is an additional effect of reducing the flow path resistance.

図３Ａ及び図３Ｂを参照して、本発明による熱交換素子の流路長による温度変化を説明すれると、次の通りである。   With reference to FIG. 3A and FIG. 3B, the temperature change due to the flow path length of the heat exchange element according to the present invention will be described as follows.

図３Ａ及び図３Ｂのそれぞれにおいて、“Ｘ”は、熱交換素子が従来の構成を有する場合、グラフＡで表すように熱交換素子の流路長によって変化する室内空気の温度と、グラフＢで表すように熱交換素子の流路長によって変化する室外空気の温度との差を示し、“Ｙ”は、熱交換素子が本発明の構成を有する場合、グラフＡで表すように熱交換素子の流路長によって変化する室内空気の温度と、グラフＢで表すように熱交換素子の流路長によって変化する室外空気の温度との差を示す。   In each of FIG. 3A and FIG. 3B, “X” indicates the temperature of the indoor air that varies depending on the flow path length of the heat exchange element as represented by graph A and the graph B when the heat exchange element has a conventional configuration. As shown, it shows the difference from the temperature of the outdoor air that changes depending on the flow path length of the heat exchange element, and “Y” indicates that the heat exchange element has the configuration of the present invention, The difference between the temperature of the indoor air that changes depending on the channel length and the temperature of the outdoor air that changes depending on the channel length of the heat exchange element as shown in graph B is shown.

まず、夏の室内冷房運転時（図３Ａ参照）では、室内空気の温度は室外空気の温度よりも相対的に低く設定される。このような室内温度と室外温度との温度差は、全熱交換器の熱交換素子５０ａでの熱交換によって減少し、よって、相対的に温度の高い室外空気は、室外に排出される室内空気と熱交換して実際の外気の温度よりも低い状態で室内に供給されるようになる。   First, during summer indoor cooling operation (see FIG. 3A), the temperature of the room air is set relatively lower than the temperature of the outdoor air. Such a temperature difference between the indoor temperature and the outdoor temperature is reduced by heat exchange in the heat exchange element 50a of the total heat exchanger, so that the outdoor air having a relatively high temperature is discharged to the outside of the room. The heat is exchanged with the indoor air in a state lower than the actual outside air temperature.

図３Ａを参照すると、従来技術による場合に比べて、本発明による熱交換素子の断面形状において熱交換がより有効に起きることが分かる。したがって、本発明による熱交換素子を使用すると、室内に供給される室外空気と室外に排出される室内空気との温度差をさらに低減することが可能になる。   Referring to FIG. 3A, it can be seen that heat exchange occurs more effectively in the cross-sectional shape of the heat exchange element according to the present invention than in the case of the prior art. Therefore, when the heat exchange element according to the present invention is used, it is possible to further reduce the temperature difference between the outdoor air supplied into the room and the indoor air discharged outside the room.

また、冬の室内暖房運転時（図３Ｂ参照）では、室内空気の温度が室外空気の温度よりも相対的に高く設定される。この場合にも、本発明による熱交換素子の断面形状を有する場合が、従来技術による熱交換素子の場合に比べて熱交換がより有効に起きることが分かる。   Further, during the indoor heating operation in winter (see FIG. 3B), the temperature of the indoor air is set relatively higher than the temperature of the outdoor air. Also in this case, it can be seen that heat exchange occurs more effectively in the case of having the cross-sectional shape of the heat exchange element according to the present invention than in the case of the heat exchange element according to the prior art.

本実施例では、全熱交換器を天井の内部に埋め込まれるものとしたが、建物の側面に設置されるものにしても良い。   In this embodiment, the total heat exchanger is embedded in the ceiling, but may be installed on the side of the building.

次に、図４及び図５を参照して、本発明による全熱交換器の第２実施例を説明する。   Next, with reference to FIG.4 and FIG.5, 2nd Example of the total heat exchanger by this invention is described.

本発明による全熱交換器の第２実施例における基本的な構成は、上記の第１実施例と同様である。ただし、熱交換素子５０ｂが複数個からなり、それぞれの熱交換素子５０ｂは、空気の流動方向に対して直列に配置される。   The basic configuration of the second embodiment of the total heat exchanger according to the present invention is the same as that of the first embodiment. However, a plurality of heat exchange elements 50b are provided, and each heat exchange element 50b is arranged in series with respect to the air flow direction.

上述の如く、建築設計上の天井高の制限によって熱交換素子の断面高さは一定の限界を有することになるが、本実施例のように、熱交換素子５０ｂを空気の流動方向に対して直列に配置することによって、熱交換素子５０ｂの断面高さを増加させることなく熱交換量を増加させることができる。   As described above, the cross-sectional height of the heat exchange element has a certain limit due to the ceiling height limitation in the architectural design. However, as in the present embodiment, the heat exchange element 50b is arranged with respect to the air flow direction. By arranging in series, the amount of heat exchange can be increased without increasing the cross-sectional height of the heat exchange element 50b.

給気ダクト１０と排気ダクト２０を流れる空気は、図４に示すように、直列配置された熱交換素子５０ｂをジグザグ形態に通過し、これにより、熱交換素子の全体熱交換面積と空気の流れる移動経路の長さは増加する。   As shown in FIG. 4, the air flowing through the air supply duct 10 and the exhaust duct 20 passes through the heat exchange elements 50 b arranged in series in a zigzag form, whereby the entire heat exchange area of the heat exchange elements and the air flow. The length of the travel path increases.

また、直列配置された熱交換素子５０ｂを通過しつつ空気の流速は次第に減少し、熱交換側面で有利となる。結果として、全体熱交換面積の増加と空気流速の減少によって全熱交換器の全熱効率が高められる効果が得られる。   Further, the air flow rate gradually decreases while passing through the heat exchange elements 50b arranged in series, which is advantageous in terms of heat exchange. As a result, the effect of increasing the total heat efficiency of the total heat exchanger by increasing the total heat exchange area and decreasing the air flow velocity is obtained.

一方、熱交換素子は、全熱交換器に着脱自在に取り付けられることが好ましい。このような着脱構造によって熱交換素子を容易に組み立てたり分離可能になる。   On the other hand, it is preferable that the heat exchange element is detachably attached to the total heat exchanger. With such a detachable structure, the heat exchange element can be easily assembled and separated.

また、全熱交換器１００は、排気用バイパス流路２６を備える。したがって、春や秋のように室内と室外の温度湿度差が小さい場合、室内空気は、熱交換素子５０ｂを通過せずに前記排気用バイパス流路２６を経て外部に排出される。これにより、熱交換素子５０ｂによる圧力損失が発生しないため、排気ファンにかかる負荷が減少し、消費電力が低減する。   Further, the total heat exchanger 100 includes an exhaust bypass passage 26. Therefore, when the temperature / humidity difference between the room and the room is small as in spring or autumn, the room air is discharged to the outside through the exhaust bypass passage 26 without passing through the heat exchange element 50b. As a result, pressure loss due to the heat exchange element 50b does not occur, so the load on the exhaust fan is reduced and power consumption is reduced.

また、全熱交換器１００は、図示してはいないが、外部空気が室内に直接流入するようにする給気用バイパス流路を備えても良い。この場合、給気用バイパス流路の一端には、室外空気の流れを制御するダンパーが取り付けられる。したがって、室外空気が熱交換されない時には、該室外空気は給気ダクトに形成された流入穴を通過し給気用バイパス流路を経由して室内に直接流入する。   Moreover, although not shown in figure, the total heat exchanger 100 may be provided with an air supply bypass passage that allows external air to flow directly into the room. In this case, a damper that controls the flow of outdoor air is attached to one end of the supply air bypass flow path. Therefore, when the outdoor air is not subjected to heat exchange, the outdoor air passes through an inflow hole formed in the air supply duct and directly flows into the room via the air supply bypass flow path.

また、全熱交換器１００は、給気ダクトに流れる空気の流路上に、室外空気中の異物をろ過するフィルタ部（図示せず）を備えても良い。このフィルタ部を通過しつつ室外空気中の異物がろ過され清浄な空気が室内に供給される。   Further, the total heat exchanger 100 may include a filter unit (not shown) for filtering foreign matter in the outdoor air on the flow path of the air flowing through the air supply duct. Foreign matters in the outdoor air are filtered while passing through the filter unit, and clean air is supplied into the room.

ここで、フィルタ部は、ホコリなどの異物を捕集するために繊維マット状に構成された集塵フィルタを備えてなる。さらに、フィルタ部は、空気中の細菌を除去する坑菌フィルタ、フィルタを通過した微細ホコリ及び揮発性有機化合物を除去する光触媒コレクタ、臭いを除去する脱臭フィルタ、陰イオン発生部などを備えて構成されるか、これらの組合によって構成されることができる。   Here, the filter unit includes a dust collection filter configured in a fiber mat shape to collect foreign matters such as dust. In addition, the filter unit includes an antibacterial filter that removes bacteria in the air, a photocatalyst collector that removes fine dust and volatile organic compounds that have passed through the filter, a deodorizing filter that removes odors, an anion generator, and the like. Can be constituted by these unions.

次に、図６を参照して、本発明による全熱交換器の第３実施例について説明する。   Next, a third embodiment of the total heat exchanger according to the present invention will be described with reference to FIG.

The plurality of air supply fans 131 and exhaust fans 231 can be increased in air volume by being driven by a single biaxial motor. In this embodiment, the air supply fan 131 and the exhaust fan 231 are each composed of two.

また、給気ファン１３１側と排気ファン２３１側には、ファンによって排出された空気を貯留する給気チャンバー１７と排気チャンバー２７がそれぞれ備えられる。これら給気チャンバーと排気チャンバーは、給気及び排気される空気を臨時貯留することによって、給気ダクトと排気ダクトの内部に流れる空気の流動を均一にする機能を担う。   In addition, an air supply chamber 17 and an exhaust chamber 27 that store air discharged by the fans are provided on the air supply fan 131 side and the exhaust fan 231 side, respectively. The air supply chamber and the exhaust chamber have a function of making the flow of air flowing inside the air supply duct and the exhaust duct uniform by temporarily storing air supplied and exhausted.

上記の第１及び第２実施例では、給気ファンと排気ファンの回転軸を室外空気の排出方向及び室内空気排出方向と同じ方向に延設したが、本実施例では、給気ファン１３１と排気ファン２３１の回転軸を、室外空気の排出方向及び室内空気の排出方向に対してそれぞれ垂直に設置した。   In the first and second embodiments described above, the rotation shafts of the air supply fan and the exhaust fan are extended in the same direction as the outdoor air discharge direction and the indoor air discharge direction. The rotating shaft of the exhaust fan 231 was installed perpendicular to the outdoor air discharge direction and the indoor air discharge direction.
