近年、地球温暖化にともなって住宅の空調負荷を削減する要求が高まっており、優れた省エネ性と施工性を併せ持つ熱交換形換気装置が求められている。こうした熱交換形換気装置として、例えば、窓に設置して室内の換気を行う窓用の熱交換形換気装置が知られている（例えば、特許文献１参照）。 In recent years, there has been an increasing demand for reducing the air-conditioning load on houses due to global warming, and there is a demand for heat exchange type ventilation devices having both excellent energy saving and workability. As such a heat exchange type ventilation device, for example, a heat exchange type ventilation device for a window which is installed in a window to ventilate a room is known (see, for example, Patent Document 1).

以下、従来の熱交換形換気装置１０１について、図１２、図１３を参照しながら説明する。図１２は、従来の熱交換形換気装置１０１の設置例を示す概略斜視図である。図１３は、従来の熱交換形換気装置１０１の構成を示す概略斜視図である。 Hereinafter, the conventional heat exchange type ventilator 101 will be described with reference to FIGS. 12 and 13. FIG. 12 is a schematic perspective view showing an installation example of the conventional heat exchange type ventilation device 101. FIG. 13 is a schematic perspective view showing the configuration of the conventional heat exchange type ventilator 101.

図１２に示すように、熱交換形換気装置１０１は窓枠１０２に埋設されている。また、図１３に示すように、熱交換形換気装置１０１は、室内空気を取り込む排気流入口１０３と室内空気を吹き出す排気流出口１０４とを連通する排気風路内に熱交換素子１０５と排気送風機１０６とを備えている。また、熱交換形換気装置１０１は、室外空気を取り込む給気流入口１０７と室外空気を吹き出す給気流出口１０８とを連通する給気風路内に熱交換素子１０５と給気送風機１０９とを備えている。排気送風機１０６と給気送風機１０９とを運転することにより、熱交換素子１０５の内部で、排気流（室内空気）と給気流（室外空気）とが熱交換されるようになっている。 As shown in FIG. 12, the heat exchange type ventilator 101 is embedded in the window frame 102.

しかしながら、従来の熱交換形換気装置１０１は、窓枠１０２の内部に、排気流と給気流とを熱交換する熱交換素子１０５が存在するので、熱交換に必要な面積が窓枠部分に制限される。このため、特に冬季の場合、従来の熱交換形換気装置１０１では、十分な熱交換ができずに、室内への吹き出し温度が低下し、快適性が損なわれるという課題があった。一方、十分な熱交換を行うために窓枠１０２を大型化する場合には、窓としての採光面積が小さくなるという課題が生じることが懸念される。 However, in the conventional heat exchange type ventilation device 101, since the heat exchange element 105 that exchanges heat between the exhaust flow and the supply airflow exists inside the window frame 102, the area required for heat exchange is limited to the window frame portion. Will be done. For this reason, especially in winter, the conventional heat exchange type ventilation device 101 has a problem that sufficient heat exchange cannot be performed, the temperature of the blown air into the room is lowered, and the comfort is impaired. On the other hand, when the window frame 102 is enlarged in order to perform sufficient heat exchange, there is a concern that the lighting area of the window becomes small.

本発明は、上記課題を解決するためになされたものであり、窓枠を小型化しつつ、快適性を向上可能な熱交換形換気装置を提供することを目的とする。 The present invention has been made to solve the above problems, and an object of the present invention is to provide a heat exchange type ventilation device capable of improving comfort while reducing the size of a window frame.

そして、この目的を達成するために、本発明に係る熱交換形換気装置は、室内側に位置する室内側採光部と室外側に位置する室外側採光部とを有する採光部と、室内側採光部と室外側採光部とに挟まれる位置において採光部と並設され、室内側より取り込んで室外側へ排気される室内空気と、室外側より取り込んで室内側へ給気される室外空気との間で熱交換を行う熱交換部とを有して構成される熱交換形換気セルを複数備える。複数の熱交換形換気セルは、窓枠の内側において、熱交換形換気セルの風路が第一方向に沿って直列に連通して構成されている。 Then, in order to achieve this object, the heat exchange type ventilation device according to the present invention has a daylighting unit having an indoor daylighting unit located on the indoor side and an outdoor daylighting unit located on the outdoor side, and an indoor daylighting unit. The indoor air, which is installed side by side with the lighting unit at the position sandwiched between the unit and the outdoor lighting unit, is taken in from the indoor side and exhausted to the outdoor side, and the outdoor air taken in from the outdoor side and supplied to the indoor side. A plurality of heat exchange type ventilation cells configured to include a heat exchange unit that exchanges heat between them are provided. The plurality of heat exchange type ventilation cells are configured such that the air passages of the heat exchange type ventilation cells communicate in series along the first direction inside the window frame.

本発明によれば、窓枠を小型化しつつ、快適性を向上可能な熱交換形換気装置を提供することができる。 According to the present invention, it is possible to provide a heat exchange type ventilation device capable of improving comfort while reducing the size of the window frame.

本発明に係る熱交換形換気装置は、室内側に位置する室内側採光部と室外側に位置する室外側採光部とを有する採光部と、室内側採光部と室外側採光部とに挟まれる位置において採光部と並設され、室内側より取り込んで室外側へ排気される室内空気と、室外側より取り込んで室内側へ給気される室外空気との間で熱交換を行う熱交換部とを有して構成される熱交換形換気セルを複数備える。複数の熱交換形換気セルは、窓枠の内側において、熱交換形換気セルの風路が第一方向に沿って直列に連通して構成されている。 The heat exchange type ventilation device according to the present invention is sandwiched between a lighting unit having an indoor side lighting unit located on the indoor side and an outdoor lighting unit located on the outdoor side, and an indoor side lighting unit and an outdoor lighting unit. A heat exchange unit that is installed side by side with the daylighting unit at the position and exchanges heat between the indoor air that is taken in from the indoor side and exhausted to the outdoor side and the outdoor air that is taken in from the outdoor side and supplied to the indoor side. It is provided with a plurality of heat exchange type ventilation cells configured by the above. The plurality of heat exchange type ventilation cells are configured such that the air passages of the heat exchange type ventilation cells communicate in series along the first direction inside the window frame.

こうした構成によれば、従来の窓枠に熱交換素子を設けた場合と比べ、熱交換が行われる面積を大型化することが可能となり、熱交換効率を向上させることができる。よって、熱交換形換気装置は、換気の際に室内を快適な温度に保つことができ、快適性を向上させることができる。また、採光部に熱交換部を並設することで、従来窓枠に埋設されていた熱交換素子が不要となり、窓枠の小型化が可能となる。この結果、窓枠を小型化しつつ、快適性を向上可能な熱交換形換気装置を提供できる。さらには、熱交換形換気セルを複数連結して熱交換形換気装置を構成するので、熱交換形換気セル単体を大型化して熱交換形換気装置を構成する場合に比べて、装置の大型化も容易に実現できる。 According to such a configuration, it is possible to increase the area where heat exchange is performed and improve the heat exchange efficiency as compared with the case where the heat exchange element is provided in the conventional window frame. Therefore, the heat exchange type ventilation device can keep the room at a comfortable temperature during ventilation, and can improve the comfort. Further, by arranging the heat exchange unit in parallel with the lighting unit, the heat exchange element conventionally embedded in the window frame becomes unnecessary, and the window frame can be miniaturized. As a result, it is possible to provide a heat exchange type ventilation device capable of improving comfort while reducing the size of the window frame. Furthermore, since a plurality of heat exchange type ventilation cells are connected to form a heat exchange type ventilation device, the size of the device is larger than when the heat exchange type ventilation cell is enlarged to form a heat exchange type ventilation device. Can be easily realized.

また、本発明に係る熱交換形換気装置では、第一方向に沿って直列に連通して構成された複数の熱交換形換気セルからなる熱交換形換気セル群を複数備える。そして、複数の熱交換形換気セル群は、第一方向と直交する第二方向に沿って並列に設けられている。このようにすることで、熱交換形換気装置の大型化を第二方向にも容易に実現できる。 Further, the heat exchange type ventilation device according to the present invention includes a plurality of heat exchange type ventilation cell groups including a plurality of heat exchange type ventilation cells configured to communicate in series along the first direction. A plurality of heat exchange type ventilation cell groups are provided in parallel along the second direction orthogonal to the first direction. By doing so, it is possible to easily realize an increase in the size of the heat exchange type ventilation device in the second direction as well.

また、本発明に係る熱交換形換気装置では、第一方向に沿って直列に連通して構成された複数の熱交換形換気セルは、室内側の風路が排気風路で構成され、室外側の風路が給気風路で構成されている。このようにすることで、給気風路に流れる室外空気によって室内空気が冷却されるのを抑制することができる。つまり、室内側採光部の室内側の室内空気の温度が低下することによって生じる結露（室内側採光部の室内側表面での結露）を抑制することができる。 Further, in the heat exchange type ventilation device according to the present invention, in the plurality of heat exchange type ventilation cells configured by communicating in series along the first direction, the air passage on the indoor side is composed of the exhaust air passage, and the room The outer air passage is composed of the air supply air passage. By doing so, it is possible to prevent the indoor air from being cooled by the outdoor air flowing through the air supply air passage. That is, it is possible to suppress dew condensation caused by a decrease in the temperature of the indoor air on the indoor side of the indoor lighting unit (condensation on the indoor surface of the indoor lighting unit).

また、本発明に係る熱交換形換気装置では、窓枠は、室内側に設けられ、室内空気を取り込む排気流入口と、室外側に設けられ、室内空気を吹き出す排気流出口と、室外側に設けられ、室外空気を取り込む給気流入口と、室内側に設けられ、室外空気を吹き出す給気流出口と、排気流入口から排気流出口へと室内空気を送風する排気送風機と、給気流入口から給気流出口へと室外空気を送風する給気送風機とを有する。そして、排気風路は、排気流入口と排気流出口とを連通して構成され、給気風路は、給気流入口と給気流出口とを連通して構成されている。このようにすることで、室内空気または室外空気が流れる風路の断面積を大きくでき、圧力損失を小さく抑えることができる。よって、排気送風機および給気送風機の駆動を小さく抑えることができ、省エネルギー運転と送風機（排気送風機および給気送風機）の静音化を実現できる。 Further, in the heat exchange type ventilation device according to the present invention, the window frame is provided on the indoor side, the exhaust inlet that takes in the indoor air, the exhaust outlet that is provided on the outdoor side and blows out the indoor air, and the outdoor side. An air supply inlet that is provided to take in outdoor air, an air supply outlet that is provided on the indoor side to blow out outdoor air, an exhaust blower that blows indoor air from the exhaust air inlet to the exhaust air outlet, and an exhaust air blower that blows indoor air from the exhaust air inlet. It has an air supply blower that blows outdoor air to the airflow outlet. The exhaust air passage is configured to communicate with the exhaust inlet and the exhaust outlet, and the air supply air passage is configured to communicate with the air supply inlet and the airflow outlet. By doing so, the cross-sectional area of the air passage through which the indoor air or the outdoor air flows can be increased, and the pressure loss can be suppressed to be small. Therefore, the drive of the exhaust blower and the air supply blower can be suppressed to be small, and energy saving operation and noise reduction of the blower (exhaust blower and air supply blower) can be realized.

また、本発明に係る熱交換形換気装置では、室内空気は、窓枠の上辺部に設けられた排気流入口から取り込まれ、排気風路を流通して、窓枠の下辺部に設けられた排気流出口から吹き出される。室外空気は、窓枠の下辺部に設けられた給気流入口から取り込まれ、給気風路を流通して、窓枠の上辺部に設けられた前記給気流出口から吹き出される。そして、排気風路の空気流れ方向と給気風路の空気流れ方向とは互いに対向している。このようにすることで、空気流れに垂直な方向に均一である面温度分布で熱交換することができる。つまり、熱交換部（排気風路を流通する室内空気）の面温度分布の局所的な偏りを軽減することによって、冬季の場合には、室内側採光部の室内側の室内空気の温度の局所的な低下が抑制され、室内側採光部の室内側表面での結露を抑制することができる。 Further, in the heat exchange type ventilation device according to the present invention, the indoor air is taken in from the exhaust inlet provided on the upper side of the window frame, flows through the exhaust air passage, and is provided on the lower side of the window frame. It is blown out from the exhaust outlet. The outdoor air is taken in from the airflow inlet provided at the lower side of the window frame, circulates through the air supply air passage, and is blown out from the airflow outlet provided at the upper side of the window frame. The air flow direction of the exhaust air passage and the air flow direction of the air supply air passage are opposite to each other. By doing so, heat exchange can be performed with a surface temperature distribution that is uniform in the direction perpendicular to the air flow. That is, by reducing the local bias of the surface temperature distribution of the heat exchange section (indoor air flowing through the exhaust air passage), in the case of winter, the temperature of the indoor air inside the indoor lighting section is local. Dew condensation on the indoor surface of the indoor lighting unit can be suppressed.

The heat exchange type ventilation cell 1a corresponding to the location can be selectively replaced or cleaned. As a result, the maintainability of the heat exchange type ventilator 1 can be improved.

（４）熱交換形換気セル１ａの選択的な交換が可能であるので、熱交換形換気装置１に対して、新たな機能／デザイン（ディスプレイ、タッチパネル、太陽パネル、防犯センサ、空質センサ、色付きガラス、摺りガラス、等）の追加が可能となる。 (4) Since the heat exchange type ventilation cell 1a can be selectively replaced, new functions / designs (display, touch panel, solar panel, security sensor, air quality sensor, etc.) are provided for the heat exchange type ventilation device 1. Colored glass, frosted glass, etc.) can be added.

（５）熱交換形換気セル１ａは、運搬／生産／サイズ展開が容易であるので、熱交換形換気セル単体を大型化して熱交換形換気装置１を構成する場合に比べて、熱交換形換気装置１の低コスト化を実現することができる。 (5) Since the heat exchange type ventilation cell 1a is easy to transport / produce / expand in size, it is a heat exchange type as compared with the case where the heat exchange type ventilation cell alone is enlarged to form the heat exchange type ventilation device 1. It is possible to reduce the cost of the ventilation device 1.

（６）熱交換形換気装置１では、上下方向に沿って直列に連通して構成された複数の熱交換形換気セル１ａは、室内側の風路が排気風路１７で構成され、室外側の風路が給気風路１８で構成される。このようにすることで、給気風路１８に流れる室外空気７によって室内空気６が冷却されるのを抑制することができる。つまり、室内側採光部１４ａの室内側の室内空気６の温度が低下することによって生じる結露（室内側採光部１４ａの室内側表面での結露）を抑制することができる。 (6) In the heat exchange type ventilation device 1, the plurality of heat exchange type ventilation cells 1a configured to communicate in series along the vertical direction have an indoor air passage composed of an exhaust air passage 17, and the outdoor side. The air passage is composed of the air supply air passage 18. By doing so, it is possible to prevent the indoor air 6 from being cooled by the outdoor air 7 flowing through the air supply air passage 18. That is, it is possible to suppress dew condensation (condensation on the indoor side surface of the indoor side lighting unit 14a) caused by a decrease in the temperature of the indoor side indoor air 6 of the indoor side lighting unit 14a.

（７）熱交換形換気装置１は、室内側採光部１４と熱交換部５の伝熱板１６との間に排気風路１７が形成され、室外側採光部１５と伝熱板１６との間に給気風路１８が形成されている。これにより、室内空気６または室外空気７が流れる風路の断面積を大きくでき、圧力損失を小さく抑えることができる。よって、排気送風機１２および給気送風機１３の駆動を小さく抑えることができ、省エネルギー運転と送風機（排気送風機１２および給気送風機１３）の静音化を実現できる。 (7) In the heat exchange type ventilation device 1, an exhaust air passage 17 is formed between the indoor side lighting unit 14 and the heat transfer plate 16 of the heat exchange unit 5, and the outdoor light collection unit 15 and the heat transfer plate 16 are connected to each other. An air supply air passage 18 is formed between them. As a result, the cross-sectional area of the air passage through which the indoor air 6 or the outdoor air 7 flows can be increased, and the pressure loss can be suppressed to a small value. Therefore, the drive of the exhaust blower 12 and the air supply blower 13 can be suppressed to be small, and energy saving operation and noise reduction of the blowers (exhaust blower 12 and air supply blower 13) can be realized.

（８）排気風路１７を流通する室内空気６の空気流れ方向と給気風路１８を流通する室外空気７の空気流れ方向とが互いに対向することによって、空気流れに垂直な方向に均一である面温度分布で熱交換することができる。つまり、熱交換部５（排気風路１７を流通する室内空気６）の面温度分布の局所的な偏りを軽減することによって、冬季の場合には、室内側採光部１４の室内側の室内空気６の温度の局所的な低下が抑制され、室内側採光部１４の室内側表面での結露をさらに抑制することができる。 (8) The air flow direction of the indoor air 6 flowing through the exhaust air passage 17 and the air flow direction of the outdoor air 7 flowing through the air supply air passage 18 face each other, so that the air flow direction is uniform in the direction perpendicular to the air flow. Heat can be exchanged by the surface temperature distribution. That is, by reducing the local bias of the surface temperature distribution of the heat exchange unit 5 (indoor air 6 flowing through the exhaust air passage 17), in the case of winter, the indoor air inside the indoor lighting unit 14 The local decrease in the temperature of No. 6 is suppressed, and the dew condensation on the indoor surface of the indoor lighting unit 14 can be further suppressed.

（９）第一中空層２１を介して対向する一対の第一採光板２２で構成された室内側採光部１４を設けたことによって、室内側採光部１４の室内側の室内空気６と、排気風路１７を流通する室内空気６（室外空気７と熱交換して温度が低下した室内空気６）との間での熱伝達が抑制される。このため、冬季など室外空気７の温度が低い場合でも、室内側採光部１４の室内側表面の室内空気６の温度が、室外空気７と熱交換して温度が低下した室内空気６によって低下することが抑制される。この結果、室内側採光部１４の室内側の室内空気６の温度が低下することによって生じる結露（室内側採光部１４の室内側表面での結露）を抑制することができる。つまり、室内側表面での結露を抑制することが可能な熱交換形換気装置１とすることができる。 (9) By providing the indoor side lighting unit 14 composed of a pair of first lighting plates 22 facing each other via the first hollow layer 21, the indoor side indoor air 6 and the exhaust of the indoor side lighting unit 14 Heat transfer between the indoor air 6 flowing through the air passage 17 (indoor air 6 whose temperature has dropped by exchanging heat with the outdoor air 7) is suppressed. Therefore, even when the temperature of the outdoor air 7 is low, such as in winter, the temperature of the indoor air 6 on the indoor surface of the indoor lighting unit 14 is lowered by the indoor air 6 whose temperature has dropped due to heat exchange with the outdoor air 7. Is suppressed. As a result, it is possible to suppress dew condensation (condensation on the indoor surface of the indoor lighting unit 14) caused by a decrease in the temperature of the indoor air 6 of the indoor lighting unit 14. That is, the heat exchange type ventilation device 1 can suppress dew condensation on the indoor surface.

（１０）室外側採光部１５は、第二中空層２３を介して対向する一対の第二採光板２４で構成されている。このため、室外側採光部１５によって、室外から熱交換部５（給気風路１８を流通する室外空気７）への熱伝達を抑制することができる。すなわち、冬季の場合には、給気風路１８を流通する室外空気７（室内空気６と熱交換して温度が上昇した室外空気７）の温度が、室外側採光部１５の室外側の室外空気７によって低下することが抑えられるので、結果として排気風路１７を流通する室内空気６の温度を上昇させることができる。この結果、排気風路１７内の伝熱板１６の表面での結露の発生自体が抑制され、視認性の低下がさらに抑制された熱交換形換気装置１とすることができる。 (10) The outdoor daylighting unit 15 is composed of a pair of second daylighting plates 24 facing each other via the second hollow layer 23. Therefore, the outdoor lighting unit 15 can suppress heat transfer from the outside to the heat exchange unit 5 (outdoor air 7 flowing through the air supply air passage 18). That is, in the winter season, the temperature of the outdoor air 7 (outdoor air 7 whose temperature has risen by exchanging heat with the indoor air 6) flowing through the air supply air passage 18 is the outdoor air outside the outdoor light collecting unit 15. As a result, the temperature of the indoor air 6 flowing through the exhaust air passage 17 can be raised because the temperature is suppressed from being lowered by 7. As a result, the heat exchange type ventilation device 1 can be obtained in which the occurrence of dew condensation on the surface of the heat transfer plate 16 in the exhaust air passage 17 is suppressed and the decrease in visibility is further suppressed.

一方、夏季の場合には、給気風路１８を流通する室外空気７（室内空気６と熱交換して温度が上昇した室外空気７）の温度が、室外側採光部１５の室外側の室外空気７によってさらに上昇することが抑えられる。このため、室外空気７を室内に導入した際に生じる室内温度の上昇を抑制することができる。この結果、熱交換形換気装置１は、室外空気７の導入に伴う室内温度の上昇を補うための室内冷房の負荷を軽減することができる。 On the other hand, in the summer, the temperature of the outdoor air 7 (outdoor air 7 whose temperature has risen by exchanging heat with the indoor air 6) flowing through the air supply air passage 18 is the outdoor air outside the outdoor lighting unit 15. Further increase is suppressed by 7. Therefore, it is possible to suppress an increase in the indoor temperature that occurs when the outdoor air 7 is introduced into the room. As a result, the heat exchange type ventilation device 1 can reduce the load of indoor cooling for compensating for the increase in indoor temperature due to the introduction of the outdoor air 7.

（１１）熱交換形換気装置１は、採光部４に並設した熱交換部５を備える。このため、太陽光（日光）の輻射熱によって熱交換部５の伝熱板１６の表面温度が上昇し、給気風路１８を流通する室外空気７の温度を上昇させることができる。この結果、排気風路１７内の伝熱板１６の表面での結露の発生自体が抑制され、視認性の低下がさらに抑制された熱交換形換気装置１とすることができる。 (11) The heat exchange type ventilation device 1 includes a heat exchange unit 5 arranged in parallel with the daylighting unit 4. Therefore, the surface temperature of the heat transfer plate 16 of the heat exchange unit 5 rises due to the radiant heat of sunlight (sunlight), and the temperature of the outdoor air 7 flowing through the air supply air passage 18 can be raised. As a result, the heat exchange type ventilation device 1 can be obtained in which the occurrence of dew condensation on the surface of the heat transfer plate 16 in the exhaust air passage 17 is suppressed and the decrease in visibility is further suppressed.

（１２）熱交換形換気装置１は、採光部４に並設した熱交換部５を備える。このため、冬季など室外空気７の温度が低い場合、室外空気７が給気風路１８を流通する際に太陽光（日光）の輻射熱によって加熱されるので、室外空気７を室内に導入した際に生じる室内温度の低下を抑制することができる。この結果、熱交換形換気装置１は、室外空気７の導入に伴う室内温度の低下を補うための室内暖房の負荷を軽減することができる。 (12) The heat exchange type ventilation device 1 includes a heat exchange unit 5 arranged in parallel with the daylighting unit 4. Therefore, when the temperature of the outdoor air 7 is low, such as in winter, the outdoor air 7 is heated by the radiant heat of sunlight (sunlight) when it flows through the air supply air passage 18, so that when the outdoor air 7 is introduced into the room, The resulting decrease in indoor temperature can be suppressed. As a result, the heat exchange type ventilator 1 can reduce the load of the indoor heating for compensating for the decrease in the indoor temperature due to the introduction of the outdoor air 7.

（１３）熱交換形換気装置１は、排気流入口８に排気フィルタが設置されるとともに、給気流入口１０に給気フィルタが設置されている。このため、室内空間および室外空間の埃などの固形物が熱交換部５へ流入するのを防止することができる。この結果、熱交換部５の内部に固形物が詰まり、固形物が通風抵抗となることで排気風量および給気風量が減少するのを防止するとともに、伝熱板１６の表面に付着する汚れを防止することができ、窓としての採光機能（または視認性）の低下を抑制することができる。 (13) In the heat exchange type ventilator 1, an exhaust filter is installed at the exhaust inlet 8 and an air supply filter is installed at the air supply inlet 10. Therefore, it is possible to prevent solid materials such as dust in the indoor space and the outdoor space from flowing into the heat exchange unit 5. As a result, the inside of the heat exchange unit 5 is clogged with solid matter, and the solid matter becomes a ventilation resistance to prevent the exhaust air volume and the supply air volume from decreasing, and also to prevent dirt adhering to the surface of the heat transfer plate 16. It can be prevented, and the deterioration of the lighting function (or visibility) as a window can be suppressed.

以上、本発明に関して実施の形態をもとに説明した。これらの実施の形態は例示であり、それらの各構成要素あるいは各処理プロセスの組合せにいろいろな変形例が可能なこと、またそうした変形例も本発明の範囲にあることは当業者に理解されるところである。 The present invention has been described above based on the embodiments. It will be appreciated by those skilled in the art that these embodiments are exemplary and that various variations of each of these components or combinations of processing processes are possible and that such modifications are also within the scope of the present invention. By the way.

本実施の形態では、熱交換形換気セル１ａの採光部４ａとして、第一中空層２１を有する室内側採光部１４ａと第二中空層２３を有する室外側採光部１５ａとからなる構成としたが、これに限られない。例えば、採光部４ａとして、中空層を有さない室内側採光部１４ａ（例えば、単体の第一採光板２２のみ）と第二中空層２３を有する室外側採光部１５とからなる構成にしてもよい。このようにすることで、複数の熱交換形換気セル１ａを連結して構成される熱交換形換気装置１の軽量化・薄型化が可能となる。 In the present embodiment, the lighting unit 4a of the heat exchange type ventilation cell 1a is composed of an indoor lighting unit 14a having the first hollow layer 21 and an outdoor lighting unit 15a having the second hollow layer 23. , Not limited to this. For example, the lighting unit 4a may be composed of an indoor lighting unit 14a having no hollow layer (for example, only a single first lighting plate 22) and an outdoor lighting unit 15 having a second hollow layer 23. Good. By doing so, it is possible to reduce the weight and thickness of the heat exchange type ventilation device 1 configured by connecting a plurality of heat exchange type ventilation cells 1a.

また、採光部４ａとして、中空層が複数並設された室内側採光部１４ａと第二中空層２３を有する室外側採光部１５とからなる構成にしてもよい。このようにすることで、複数の熱交換形換気セル１ａを連結して構成される熱交換形換気装置１の断熱性能を向上させることが可能となる。 Further, the lighting unit 4a may be composed of an indoor side lighting unit 14a in which a plurality of hollow layers are arranged side by side and an outdoor lighting unit 15 having a second hollow layer 23. By doing so, it is possible to improve the heat insulating performance of the heat exchange type ventilation device 1 configured by connecting a plurality of heat exchange type ventilation cells 1a.

本実施の形態では、熱交換形換気セル１ａを構成する伝熱板１６（特に排気風路１７側の伝熱板１６の表面）に親水性の保護層を設けてもよい。このようにすることで、複数の熱交換形換気セル１ａを連結して熱交換形換気装置１を構成した場合、この親水性の保護層によって、排気風路１７内の伝熱板１６の表面では、伝熱板１６の表面に発生する結露水が水玉（水滴）にはならずに、伝熱板１６の表面に薄く拡がった状態となる。これにより、伝熱板１６の表面を透過する光の乱反射（水玉状の結露水に起因した光の乱反射）を抑制することができる。この結果、冬季など室外空気７の温度が低い場合に、採光部４から視認される熱交換部５（伝熱板１６の表面）での結露に起因した視認性の低下を抑制することができる。 In the present embodiment, a hydrophilic protective layer may be provided on the heat transfer plate 16 (particularly the surface of the heat transfer plate 16 on the exhaust air passage 17 side) constituting the heat exchange type ventilation cell 1a. By doing so, when a plurality of heat exchange type ventilation cells 1a are connected to form the heat exchange type ventilation device 1, the surface of the heat transfer plate 16 in the exhaust air passage 17 is provided by the hydrophilic protective layer. Then, the dew condensation water generated on the surface of the heat transfer plate 16 does not become polka dots (water droplets), but spreads thinly on the surface of the heat transfer plate 16. As a result, diffused reflection of light passing through the surface of the heat transfer plate 16 (diffuse reflection of light caused by polka-dot-shaped condensed water) can be suppressed. As a result, when the temperature of the outdoor air 7 is low, such as in winter, it is possible to suppress a decrease in visibility due to dew condensation on the heat exchange unit 5 (the surface of the heat transfer plate 16) that is visible from the lighting unit 4. ..

なお、保護層としては、例えば、光触媒活性を有する粒子が分散されたシリコン酸化物層を用いてもよい。ここで、光触媒活性を有する粒子とは、光（例えば、紫外線）の照射によって親水基（水酸基）を生成する光触媒の粒子である。光触媒としては、例えば、酸化チタン、酸化タングステン等が用いられてもよい。なお、「親水性を有する」とは、少なくとも水との接触角が１０°程度以下となっている状態を示す。 As the protective layer, for example, a silicon oxide layer in which particles having photocatalytic activity are dispersed may be used. Here, the particles having photocatalytic activity are particles of a photocatalyst that generate hydrophilic groups (hydroxyl groups) by irradiation with light (for example, ultraviolet rays). As the photocatalyst, for example, titanium oxide, tungsten oxide and the like may be used. In addition, "having hydrophilicity" means a state in which the contact angle with water is at least about 10 ° or less.

本実施の形態では、排気流入口８（あるいは排気流入口８の近傍の排気風路１７）に排気フィルタを取り付けるとともに、給気流入口１０（あるいは給気流入口１０の近傍の給気風路１８）に給気フィルタを取り付ける構成としたが、これに限られない。例えば、室外空間には室内空間よりも花粉あるいは埃などの固形物が多く存在しているため、給気流入口１０側のみに給気フィルタを取り付ける構成としてもよい。これにより、少なくとも排気風路１７よりも固形物が詰まりやすい給気風路１８への固形物の流入（給気風路１８の給気風量の減少）を防止することができる。 In the present embodiment, an exhaust filter is attached to the exhaust inlet 8 (or the exhaust air passage 17 near the exhaust inlet 8), and the air supply inlet 10 (or the air supply passage 18 near the air supply inlet 10) is provided with an exhaust filter. The configuration is such that an air supply filter is attached, but the configuration is not limited to this. For example, since more solid matter such as pollen or dust is present in the outdoor space than in the indoor space, the air supply filter may be attached only to the air supply inlet 10 side. This makes it possible to prevent at least the inflow of solid matter into the air supply air passage 18 (decrease in the amount of air supply air in the air supply air passage 18), which is more likely to be clogged with solid matter than the exhaust air passage 17.

本発明に係る熱交換形換気装置は、室内空気と室外空気との間での熱交換を可能とする熱交換形換気装置として有用である。主に建物の窓に用いられることで効果を奏する。 The heat exchange type ventilator according to the present invention is useful as a heat exchange type ventilator that enables heat exchange between indoor air and outdoor air. It is effective when it is mainly used for windows of buildings.
