Description

車両用換気装置Vehicle ventilation system
　本発明は、自動車の車内の換気を行う車両用換気装置に関する。 The present invention relates to a vehicle ventilation device that ventilates the inside of an automobile.
　従来、自動車の空気調和換気システムでは、車内空気の清浄化とフロントガラスの防曇とを目的とした外気導入、および空気調和運転の実施時における温熱空気の車外への排出の抑制と排気ガスの車内への侵入防止とを目的とした内気循環が行われている。 Conventionally, in an air-conditioned ventilation system of an automobile, outside air is introduced for the purpose of purifying the air inside the vehicle and preventing fogging of the windshield, and the emission of hot air to the outside of the vehicle during air-conditioned operation is suppressed and exhaust gas is discharged. The inside air is circulated for the purpose of preventing intrusion into the vehicle.
　近年、環境問題が重視されるようになるにつれて、自動車は、電気を使用する電気自動車が普及しつつある。しかしながら、電気自動車は、ガソリン車と比較してエンジンの排熱利用による車内の暖房がされ難い。特に冬季では、電気自動車は、暖房負荷を電気から賄うこととなるため１回の充電で走行できる走行距離が短くなる、といった問題がある。このため、電気自動車では、空気調和負荷を低減させるために、熱交換を利用して給気流を暖める換気システムの利用が考えられる。 In recent years, as environmental issues have become more important, electric vehicles that use electricity are becoming widespread. However, compared to gasoline-powered vehicles, electric vehicles are less likely to be heated inside by utilizing the exhaust heat of the engine. Especially in winter, the electric vehicle has a problem that the mileage that can be traveled on one charge is shortened because the heating load is covered by electricity. Therefore, in an electric vehicle, in order to reduce the air conditioning load, it is conceivable to use a ventilation system that warms the air supply by using heat exchange.
　熱交換を利用して自動車の空気調和を行う技術として、特許文献１には、自動車において車外の空気を取り入れ、車室内の空気調和を行う空気調和装置の熱交換器に空気清浄作用を行なわせることにより車室内の空気を迅速に清浄化し、しかもそのエネルギーロスが少なく、かつ、寿命の長い自動車における空気清浄熱交換装置が開示されている。 As a technique for air-conditioning an automobile by using heat exchange, Patent Document 1 describes that the heat exchanger of an air conditioner that takes in the air outside the vehicle and harmonizes the air inside the vehicle performs an air purifying action. Disclosed is an air purifying heat exchange device for an automobile that quickly purifies the air in the vehicle interior, has a small energy loss, and has a long life.
　ここで、特許文献１に開示された熱交換器の間隔板は、臭気成分の吸着性を有する活性炭繊維等で成形されているが、再生手段がないため、活性炭繊維等の吸着性が飽和した場合には車内に臭気成分が侵入して乗務者の快適性が損なわれる。 Here, the interval plate of the heat exchanger disclosed in Patent Document 1 is formed of activated carbon fiber or the like having an odor component adsorptive property, but the adsorptivity of the activated carbon fiber or the like is saturated because there is no regenerating means. In some cases, the odor component invades the inside of the vehicle and the comfort of the crew is impaired.
　一方、特許文献２には、再生可能な熱交換素子により室内空気と外気の熱交換を行う熱交換換気扇が記載されている。特許文献２に記載された熱交換換気扇は、通常運転時は外気中に含まれる窒素酸化物の除去を行う。また、熱交換換気扇は、吸着体の窒素酸化物吸着性能が低下した時点で発熱体を加熱し、同時に吸引ファンを通常時と逆回転させることにより吸着体から脱着した窒素酸化物を戸外に排出することにより吸着体の再生を行う。 On the other hand, Patent Document 2 describes a heat exchange ventilation fan that exchanges heat between indoor air and outside air using a renewable heat exchange element. The heat exchange ventilation fan described in Patent Document 2 removes nitrogen oxides contained in the outside air during normal operation. In addition, the heat exchange ventilation fan heats the heating element when the nitrogen oxide adsorption performance of the adsorbent deteriorates, and at the same time, rotates the suction fan in the reverse direction to discharge the nitrogen oxides desorbed from the adsorbent to the outside. By doing so, the adsorbent is regenerated.

　しかしながら、上記特許文献２に開示された熱交換換気扇は、吸着体の再生を行う際に、発熱体を加熱すると同時に吸引ファンを通常時と逆回転させることによって、吸着体から脱着した窒素酸化物を戸外に排出する。このため、吸着体の再生を行う際の吸引ファンのファン効率が悪く、発生する風量が少ないため、吸着体から脱着した窒素酸化物を戸外に排出することができない可能性がある。また、特許文献２に開示された熱交換換気扇は、発熱体を加熱することによって窒素酸化物を脱着させているため、エネルギーの消費が大きくなる。 However, in the heat exchange ventilation fan disclosed in Patent Document 2, when the adsorbent is regenerated, the nitrogen oxides desorbed from the adsorbent are desorbed by heating the heating element and at the same time rotating the suction fan in the reverse direction to the normal state. To the outside. For this reason, the fan efficiency of the suction fan when regenerating the adsorbent is poor, and the amount of air generated is small, so that the nitrogen oxides desorbed from the adsorbent may not be discharged to the outside. Further, the heat exchange ventilation fan disclosed in Patent Document 2 desorbs nitrogen oxides by heating a heating element, so that energy consumption increases.
　本発明は、上記に鑑みてなされたものであって、車両の空気調和負荷を低減しつつ、長期間にわたって臭気成分の吸着性を維持して換気が可能な車両用換気装置を得ることを目的とする。 The present invention has been made in view of the above, and an object of the present invention is to obtain a vehicle ventilation device capable of ventilating by maintaining the adsorptivity of odorous components for a long period of time while reducing the air conditioning load of the vehicle. And.
　上述した課題を解決し、目的を達成するために、本発明にかかる車両用換気装置は、車両の外部である車外と車両の内部である車内とを結ぶ給気風路と、車外と車内とを結び給気風路と交差された排気風路と、給気風路に設けられて車内に向かう給気流を給気風路の内部に発生させる給気用送風機と、排気風路に設けられて車内から車外に向かう排気流を排気風路の内部に発生させる排気用送風機と、を備える。車両用換気装置は、給気流と排気流とのうち一方が流れる第１の気体流路と、給気流と排気流とのうち他方が流れる第２の気体流路と、を備えて第１の気体流路を流れる気流と第２の気体流路を流れる気流との間で熱交換させる熱交換素子と、第１の気体流路および第２の気体流路のうち少なくとも一方に配置されて臭気成分を吸着する吸着剤と、熱交換素子における給気流と排気流の流路を切り換える風路切換弁と、を備える。風路切換弁は、給気流が第１の気体流路を流れるとともに排気流が第２の気体流路を流れる第１の切換え状態と、排気流が第１の気体流路を流れるとともに給気流が第２の気体流路を流れる第２の切換え状態と、に切り換えられる。 In order to solve the above-mentioned problems and achieve the object, the vehicle ventilation device according to the present invention has an air supply air passage connecting the outside of the vehicle and the inside of the vehicle, and the outside and the inside of the vehicle. An exhaust air passage that intersects the knot air passage, an air supply blower that is installed in the air supply air passage and generates airflow toward the inside of the vehicle inside the air supply air passage, and an air supply blower that is installed in the exhaust air passage from the inside of the vehicle to the outside of the vehicle.

　車両用空気調和換気装置２０は、車内１０２の換気を行う車両用換気装置１０と、車内１０２の暖房または冷房といった空気調和を行うための空気調和部１４と、を備える。車両用換気装置１０は、給気風路２１と、排気風路２２と、を備える。 The vehicle air-conditioning ventilation device 20 includes a vehicle ventilation device 10 that ventilates the inside of the vehicle 102, and an air-conditioning unit 14 for performing air conditioning such as heating or cooling of the inside of the vehicle 102. The vehicle ventilation device 10 includes an air supply air passage 21 and an exhaust air passage 22.
　給気風路２１は、車内１０２に開放された開口である車内給気口１４２と、新鮮な空気である外気を取り込むために車外に開放された開口である給気用車外開口１２１と、を後述する熱交換素子１１５を介して結ぶ風路である。すなわち、給気風路２１は、車両１００の外部である車外と車両１００の内部である車内１０２とを、熱交換素子１１５を介して連通させる。 The air supply air passage 21 will be described later with an in-vehicle air supply port 142 which is an opening opened to the inside 102 of the vehicle and an outside air supply port 121 which is an opening opened to the outside of the vehicle to take in the outside air which is fresh air. It is an air passage connected via a heat exchange element 115. That is, the air supply air passage 21 communicates the outside of the vehicle 100 outside the vehicle and the inside 102 of the vehicle 100 with each other via the heat exchange element 115.
　給気風路２１は、熱交換素子１１５よりも給気流５６の流れ方向における上流側に設けられた上流側給気風路２１１と、熱交換素子１１５よりも給気流５６の流れ方向における下流に設けられた下流側給気風路２１２と、を有する。 The air supply air passage 21 is provided on the upstream side air supply air passage 211 provided on the upstream side in the flow direction of the air flow 56 with respect to the heat exchange element 115, and on the downstream side in the flow direction of the air flow 56 with respect to the heat exchange element 115. It has a downstream air supply air passage 212.
　排気風路２２は、車内１０２に開放された開口である排気用車内開口１２４と、車外に開放された開口である排気用車外開口１２２とを、熱交換素子１１５を介して結ぶ風路である。すなわち、排気風路２２は、車外と車内１０２とを、熱交換素子１１５を介して連通させる。給気風路２１と排気風路２２とは風路の途中で交差している。 The exhaust air passage 22 is an air passage that connects the exhaust vehicle interior opening 124, which is an opening opened to the vehicle interior 102, and the exhaust vehicle exterior opening 122, which is an opening opened to the outside of the vehicle, via a heat exchange element 115. .. That is, the exhaust air passage 22 communicates the outside of the vehicle with the inside of the vehicle 102 via the heat exchange element 115. The air supply air passage 21 and the exhaust air passage 22 intersect in the middle of the air passage.
　排気風路２２は、熱交換素子１１５よりも排気流５７の流れ方向における上流側に設けられた上流側排気風路２２１と、熱交換素子１１５よりも排気流５７の流れ方向における下流に設けられた下流側排気風路２２２と、を有する。 The exhaust air passage 22 is provided on the upstream side exhaust air passage 221 provided on the upstream side in the flow direction of the exhaust flow 57 from the heat exchange element 115, and on the downstream side in the flow direction of the exhaust flow 57 from the heat exchange element 115. It has an exhaust air passage 222 on the downstream side.
　給気用車外開口１２１は、車両１００の外面における上面に設けられることが好ましい。給気用車外開口１２１を車両１００の外面における上面に設けることにより、車外の清浄な空気を取り入れることができる。特に、給気用車外開口１２１をフロントガラス１０１の下端付近に設けることにより、給気用車外開口１２１の開口部を容易に設けることができる。 The air supply vehicle outer opening 121 is preferably provided on the upper surface of the outer surface of the vehicle 100. By providing the air supply vehicle outer opening 121 on the upper surface of the outer surface of the vehicle 100, clean air outside the vehicle can be taken in. In particular, by providing the air supply vehicle outer opening 121 near the lower end of the windshield 101, the opening of the air supply vehicle outer opening 121 can be easily provided.
　車内給気口１４２は、デフロスタ吹出口７、フェイス吹出口８およびフット吹出口９である。車内給気口１４２は、車内１０２の前方に設けられることが好ましい。車内給気口１４２を車内１０２の前方に設けることにより、運転席および助手席を効果的に空気調和することが可能になる。デフロスタ吹出口７からは、フロントガラス１０１へ向かって風が吹き出される。フェイス吹出口８からは、乗員の上半身へ向かって風が吹き出される。フット吹出口９からは、乗員の足下に向かって風が吹き出される。 The in-vehicle air supply port 142 is a defroster outlet 7, a face outlet 8, and a foot outlet 9. The in-vehicle air supply port 142 is preferably provided in front of the in-vehicle 102. By providing the in-vehicle air supply port 142 in front of the in-vehicle 102, the driver's seat and the passenger's seat can be effectively air-conditioned. Wind is blown from the defroster outlet 7 toward the windshield 101. From the face outlet 8, wind is blown toward the upper body of the occupant. From the foot outlet 9, wind is blown toward the feet of the occupant.
　排気用車内開口１２４は、車内１０２の後方に設けられることが好ましい。車内給気口１４２を車内１０２の前方に設け、且つ排気用車内開口１２４を車内１０２の後方に設けることにより、車内給気口１４２から排気用車内開口１２４に向けて車内１０２に空気の流れが形成されるので、車内１０２全体を空気調和することが容易になる。 It is preferable that the exhaust vehicle interior opening 124 is provided behind the vehicle interior 102. By providing the in-vehicle air supply port 142 in front of the in-vehicle 102 and providing the exhaust in-vehicle opening 124 in the rear of the in-vehicle 102, air flow from the in-vehicle air supply port 142 toward the exhaust in-vehicle opening 124 flows into the in-vehicle 102. Since it is formed, it becomes easy to air-condition the entire interior 102 of the vehicle.
　排気用車外開口１２２は、車両１００の外面における下面に設けられることが好ましい。排気用車外開口１２２が給気用車外開口１２１の近くに設けられた場合には、車両１００から車外に排出された車外排気と車外の空気である外気とで短絡が発生し、排気用車外開口１２２から車外に排気した排気が再度車内に給気されてしまう可能性がある。したがって、排気用車外開口１２２を給気用車外開口１２１の近くに設けることは、不適切である。給気用車外開口１２１を車両１００の外面における上面に設け、且つ排気用車外開口１２２を車両１００の外面における下面に設けることにより、車外排気と車外外気との短絡を抑制することができる。 It is preferable that the exhaust vehicle outer opening 122 is provided on the lower surface of the outer surface of the vehicle 100. When the exhaust vehicle outer opening 122 is provided near the air supply vehicle outer opening 121, a short circuit occurs between the vehicle outer exhaust discharged from the vehicle 100 to the outside of the vehicle and the outside air which is the air outside the vehicle, and the exhaust vehicle outer opening There is a possibility that the exhaust gas exhausted from 122 to the outside of the vehicle will be supplied to the inside of the vehicle again. Therefore, it is inappropriate to provide the exhaust vehicle outer opening 122 near the air supply vehicle outer opening 121. By providing the air supply vehicle outer opening 121 on the upper surface of the outer surface of the vehicle 100 and the exhaust vehicle outer opening 122 on the lower surface of the vehicle 100, it is possible to suppress a short circuit between the vehicle outer exhaust and the vehicle outer air.
　また、冬場では、車外排気は、車外の空気である外気よりも温度および湿度が高く、排気を車外に排出する際に排気に結露が発生する場合がある。ここで、排気用車外開口１２２を車両１００の外面における下面に設けることにより、排気を車外に排出する際に排気が結露しても、結露した水を車両１００の下側に排出することが容易になる。 Also, in winter, the temperature and humidity of the exhaust outside the vehicle are higher than the outside air, which is the air outside the vehicle, and dew condensation may occur on the exhaust when the exhaust is discharged to the outside of the vehicle. Here, by providing the exhaust vehicle outer opening 122 on the lower surface of the outer surface of the vehicle 100, even if the exhaust is condensed when the exhaust is discharged to the outside of the vehicle, the condensed water can be easily discharged to the lower side of the vehicle 100. become.

　第１の給気用送風機４は、給気風路２１である下流側給気風路２１２に設けられる。第１の給気用送風機４は、デフロスタ吹出口７、フェイス吹出口８およびフット吹出口９に向かう給気流５６を給気風路２１の内部に発生させる。第１の給気用送風機４は、給気風路２１と排気風路２２とが交差する交差部よりも給気流５６の流れ方向における下流の位置に設けられる。 The first air supply blower 4 is provided in the downstream air supply air passage 212, which is the air supply air passage 21. The first air supply blower 4 generates an air flow 56 toward the defroster air outlet 7, the face air outlet 8, and the foot air outlet 9 inside the air supply air passage 21. The first air supply blower 4 is provided at a position downstream of the intersection where the air supply air passage 21 and the exhaust air passage 22 intersect in the flow direction of the air supply air 56.
　第２の給気用送風機１１１ａは、給気風路２１である上流側給気風路２１１に設けられる。第２の給気用送風機１１１ａは、給気用車外開口１２１からデフロスタ吹出口７、フェイス吹出口８およびフット吹出口９に向かう給気流５６を給気風路２１の内部に発生させる。第２の給気用送風機１１１ａは、給気風路２１と排気風路２２とが交差する交差部よりも給気流５６の流れ方向における上流の位置に設けられる。 The second air supply blower 111a is provided in the upstream air supply air passage 211, which is the air supply air passage 21. The second air supply blower 111a generates an air flow 56 from the air supply vehicle outer opening 121 toward the defroster air outlet 7, the face air outlet 8 and the foot air outlet 9 inside the air supply air passage 21. The second air supply blower 111a is provided at a position upstream in the flow direction of the air supply air 56 from the intersection where the air supply air passage 21 and the exhaust air passage 22 intersect.

The exhaust blower 111b generates an exhaust flow 57 from the exhaust vehicle inner opening 124 toward the exhaust vehicle outer opening 122. The exhaust blower 111b is provided at a position downstream of the intersection where the air supply air passage 21 and the exhaust air passage 22 intersect in the flow direction of the exhaust flow 57.
　本実施の形態１では、１つの電動機３１で、上流側給気風路２１１に設けられた羽根車と、下流側排気風路２２２に設けられた羽根車とを回転させることで、上流側給気風路２１１に設けられた羽根車を第２の給気用送風機１１１ａとして機能させ、下流側排気風路２２２に設けられた羽根車を排気用送風機１１１ｂとして機能させている。 In the first embodiment, one electric motor 31 rotates an impeller provided in the upstream air supply air passage 211 and an impeller provided in the downstream exhaust air passage 222 to rotate the upstream air supply air. The impeller provided on the road 211 functions as the second air supply blower 111a, and the impeller provided on the downstream exhaust air passage 222 functions as the exhaust blower 111b.

The cooler 5 is provided at a position downstream of the first air supply blower 4 in the flow direction of the air flow 56. The cooler 5 cools the air supply 56 below the dew point temperature. The air supply 56 is cooled to a dew point temperature or lower by the cooler 5, so that dew condensation occurs and the humidity decreases. That is, the air supply 56 can be dehumidified by the cooler 5. The heater 6 is provided in the downstream air supply air passage 212, which is the air supply air passage 21, and performs air conditioning of the air supply air flow 56 flowing in the vehicle interior 102.

In this case, the cooler 5 is an evaporator that evaporates the refrigerant by endothermic heat. The heater 6 is a condenser that condenses the refrigerant by heat dissipation. The heater 6 may be an electric heater such as a PTC (Positive Temperature Coafficient) heater, or may be a condenser using an electric heater as an auxiliary heat source.
　車両用換気装置１０は、内気合流風路２３を備える。内気合流風路２３は、下流側給気風路２１２に合流される風路である。内気合流風路２３は、給気流５６の流れにおける熱交換素子１１５よりも下流かつ第１の給気用送風機４よりも上流の位置で下流側給気風路２１２に合流される。内気合流風路２３では、下流側給気風路２１２と合流する端部とは反対側となる端部が、図２に示すように、排気用車内開口１２４とは異なる、独立して車内１０２に開放された開口である合流用車内開口１２３となっている。内気合流風路２３は、下流側給気風路２１２と車内１０２とを結ぶ。 The vehicle ventilation device 10 includes an inside air confluence air passage 23. The internal air confluence air passage 23 is an air passage that merges with the downstream air supply air passage 212. The internal air confluence air passage 23 merges with the downstream air supply air passage 212 at a position downstream of the heat exchange element 115 in the flow of the air supply 56 and upstream of the first air supply blower 4. In the inside air merging air passage 23, the end portion opposite to the end portion merging with the downstream side air supply air passage 212 is independently located in the in-vehicle 102, which is different from the exhaust in-vehicle opening 124, as shown in FIG.

　車両用換気装置１０は、熱交換素子１１５を備える。熱交換素子１１５は、給気風路２１と排気風路２２とが交差する交差部に設けられている。熱交換素子１１５は、給気風路２１を流れる給気流５６と、排気風路２２を流れる排気流５７との間で熱交換させる熱交換器である。 The vehicle ventilation device 10 includes a heat exchange element 115. The heat exchange element 115 is provided at an intersection where the air supply air passage 21 and the exhaust air passage 22 intersect. The heat exchange element 115 is a heat exchanger that exchanges heat between the air supply 56 flowing through the air supply air passage 21 and the exhaust flow 57 flowing through the exhaust air passage 22.
　図１４は、本発明の実施の形態１における熱交換素子１１５の斜視図である。熱交換素子１１５は、交互に重ねられた仕切部材５１と間隔保持部材５２とを備える。仕切部材５１と間隔保持部材５２とは接着剤で接着されている。仕切部材５１を挟んだ一方側には、第１の層状気体流路５４が形成されている。第１の層状気体流路５４は、熱交換素子１１５における第１の気体流路であり、給気流５６と排気流５７とのうち一方が流れる。第１の層状気体流路５４は、給気風路２１の一部を構成する。 FIG. 14 is a perspective view of the heat exchange element 115 according to the first embodiment of the present invention. The heat exchange element 115 includes partition members 51 and spacing members 52 that are alternately stacked. The partition member 51 and the interval holding member 52 are adhered to each other with an adhesive. A first layered gas flow path 54 is formed on one side of the partition member 51. The first layered gas flow path 54 is the first gas flow path in the heat exchange element 115, and one of the supply air flow 56 and the exhaust flow 57 flows. The first layered gas flow path 54 forms a part of the air supply air passage 21.
　仕切部材５１を挟んだ他方側には、第２の層状気体流路５５が形成されている。第２の層状気体流路５５は、熱交換素子１１５における第２の気体流路であり、給気流５６と排気流５７とのうち他方が流れる。第２の層状気体流路５５は、排気風路２２の一部を構成する。第１の層状気体流路５４の延在方向と、第２の層状気体流路５５の延在方向とは、直交している。そして、熱交換素子１１５は、第１の層状気体流路５４を流れる気流と、第２の層状気体流路５５を流れる気流と、の間で熱交換させる。 A second layered gas flow path 55 is formed on the other side of the partition member 51. The second layered gas flow path 55 is the second gas flow path in the heat exchange element 115, and the other of the supply air flow 56 and the exhaust flow 57 flows. The second layered gas flow path 55 constitutes a part of the exhaust air passage 22. The extending direction of the first layered gas flow path 54 and the extending direction of the second layered gas flow path 55 are orthogonal to each other. Then, the heat exchange element 115 exchanges heat between the air flow flowing through the first layered gas flow path 54 and the air flow flowing through the second layered gas flow path 55.
　熱交換素子１１５が、給気流５６と排気流５７との間で温度および湿度を交換させる全熱交換の素材で構成される場合は、仕切部材５１を媒体にして給気流５６と排気流５７との間で潜熱および顕熱が交換される。 When the heat exchange element 115 is made of a material for total heat exchange that exchanges temperature and humidity between the air supply 56 and the exhaust flow 57, the air supply 56 and the exhaust flow 57 and the partition member 51 are used as a medium. Latent heat and sensible heat are exchanged between.
　熱交換素子１１５が、湿度を透過させず、温度だけを交換させる顕熱交換の素材で構成される場合は、給気流５６と排気流５７との間で仕切部材５１を媒体にして顕熱だけが交換される。顕熱交換の素材としては、例えばプラスティックが用いられる。車内１０２の空気調和換気において湿度の排出が重要視される場合には、顕熱のみが交換される熱交換素子１１５を用いることが好ましい。 When the heat exchange element 115 is made of a material for sensible heat exchange that does not allow humidity to pass through and exchanges only temperature, only sensible heat is generated using the partition member 51 as a medium between the supply airflow 56 and the exhaust flow 57. Is exchanged. As a material for sensible heat exchange, for example, plastic is used. When the discharge of humidity is important in the air-conditioned ventilation of the vehicle interior 102, it is preferable to use the heat exchange element 115 in which only sensible heat is exchanged.
　ガソリン車、またはディーゼル車の排気ガスには、窒素酸化物および未燃焼の揮発性有機化合物といった臭気成分が含まれている。そして、臭気成分である窒素酸化物および未燃焼の揮発性有機化合物が車内１０２に侵入すると、乗務者の快適性を著しく損なう。このため、車両用換気装置１０における外気導入時に、外気に含まれる臭気成分を吸着除去するために、熱交換素子１１５の仕切部材５１と間隔保持部材５２との両方、または仕切部材５１と間隔保持部材５２とのうちのどちらか一方に、臭気成分を吸着する吸着剤５８が添着されている。すなわち、熱交換素子１１５は、仕切部材５１と間隔保持部材５２との内の少なくとも一方に臭気成分を吸着する吸着剤５８が配置されている。本実施の形態１では、第１の層状気体流路５４に吸着剤５８が配置されているものとする。 Exhaust gas from gasoline-powered vehicles or diesel-powered vehicles contains odorous components such as nitrogen oxides and unburned volatile organic compounds. When nitrogen oxides and unburned volatile organic compounds, which are odorous components, invade the inside of the vehicle 102, the comfort of the crew is significantly impaired. Therefore, in order to adsorb and remove the odor component contained in the outside air when the outside air is introduced in the vehicle ventilation device 10, both the partition member 51 and the spacing member 52 of the heat exchange element 115, or the spacing between the partition member 51 and the spacing is maintained. An adsorbent 58 that adsorbs an odor component is attached to either one of the members 52. That is, in the heat exchange element 115, an adsorbent 58 that adsorbs an odor component is arranged on at least one of the partition member 51 and the interval holding member 52. In the first embodiment, it is assumed that the adsorbent 58 is arranged in the first layered gas flow path 54.
　臭気成分を吸着する吸着剤５８としては、シリカ、酸化アルミニウム、疎水性ゼオライト、親水性ゼオライト、活性炭などを単体で用いてもよいし、これらの材料の混合物などを用いてもよい。吸着剤５８は、熱交換素子１１５の基材である紙、不織布、多孔質材、樹脂などに添着されればよい。 As the adsorbent 58 that adsorbs the odor component, silica, aluminum oxide, hydrophobic zeolite, hydrophilic zeolite, activated carbon or the like may be used alone, or a mixture of these materials may be used. The adsorbent 58 may be attached to paper, a non-woven fabric, a porous material, a resin, or the like, which is the base material of the heat exchange element 115.
　これにより、車両用換気装置１０では、外気導入時に、熱交換素子１１５の仕切部材５１と間隔保持部材５２との両方、または仕切部材５１と間隔保持部材５２とのうちのどちらか一方に配置された吸着剤５８によって、給気流５６に含まれる臭気成分を除去しつつ、給気流５６と排気流５７との間の熱交換を行うことができる。すなわち、車両用換気装置１０では、外気導入時に、給気流５６と排気流５７との間の熱交換と、外気に含まれる臭気成分の除去と、を同時に行うことができる。 As a result, in the vehicle ventilation device 10, when the outside air is introduced, the heat exchange element 115 is arranged on both the partition member 51 and the interval holding member 52, or on either the partition member 51 and the interval holding member 52. The adsorbent 58 can exchange heat between the supply airflow 56 and the exhaust flow 57 while removing the odorous component contained in the supply airflow 56. That is, in the vehicle ventilation device 10, when the outside air is introduced, the heat exchange between the supply air flow 56 and the exhaust flow 57 and the removal of the odor component contained in the outside air can be performed at the same time.
　つぎに、熱交換部１１３の動作について説明する。図１５は、本発明の実施の形態１にかかる熱交換部１１３の第１の風路を説明する模式図である。図１６は、本発明の実施の形態１にかかる熱交換部１１３の第２の風路を説明する模式図である。図１５および図１６において、矢印は、車両用換気装置１０の熱交換部１１３における空気の流れを示している。図１５および図１６において、中太矢印は、熱交換素子１１５における給気流５６および排気流５７の流れを示している。 Next, the operation of the heat exchange unit 113 will be described. FIG. 15 is a schematic view illustrating a first air passage of the heat exchange unit 113 according to the first embodiment of the present invention. FIG. 16 is a schematic view illustrating a second air passage of the heat exchange unit 113 according to the first embodiment of the present invention. In FIGS. 15 and 16, the arrows indicate the air flow in the heat exchange section 113 of the vehicle ventilator 10. In FIGS. 15 and 16, the thick arrow indicates the flow of the supply airflow 56 and the exhaust flow 57 in the heat exchange element 115.
　車両用換気装置１０において、風路Ａは、上流側給気風路２１１である。風路Ｂは、熱交換素子１１５の第１の層状気体流路５４と第１の風路切換弁１１４ａとを結ぶ風路である。風路Ｃは、熱交換素子１１５の第２の層状気体流路５５と第２の風路切換弁１１４ｂとを結ぶ風路である。風路Ｄは、上流側排気風路２２１である。風路Ｅは、下流側排気風路２２２である。風路Ｆは、熱交換素子１１５の第２の層状気体流路５５と第１の風路切換弁１１４ａとを結ぶ風路である。風路Ｇは、熱交換素子１１５の第１の層状気体流路５４と第２の風路切換弁１１４ｂとを結ぶ風路である。風路Ｈは、下流側給気風路２１２である。 In the vehicle ventilation device 10, the air passage A is the upstream air supply air passage 211. The air passage B is an air passage connecting the first layered gas flow path 54 of the heat exchange element 115 and the first air passage switching valve 114a. The air passage C is an air passage connecting the second layered gas flow path 55 of the heat exchange element 115 and the second air passage switching valve 114b. The air passage D is an upstream exhaust air passage 221. The air passage E is a downstream exhaust air passage 222. The air passage F is an air passage connecting the second layered gas flow path 55 of the heat exchange element 115 and the first air passage switching valve 114a. The air passage G is an air passage connecting the first layered gas flow path 54 of the heat exchange element 115 and the second air passage switching valve 114b. The air passage H is a downstream air supply air passage 212.
　図１５に示すように、熱交換部１１３が第１の風路となっている場合、すなわち、第１の風路切換弁１１４ａおよび第２の風路切換弁１１４ｂが第１の切換え状態となっている場合、車外から車両用換気装置１０に取り込まれて風路Ａを流れる給気流５６である外気には臭気成分が含まれている。外気は、風路Ａから、第１の風路切換弁１１４ａによって構成される第１の給排気風路１１７、風路Ｂ、熱交換素子１１５の第１の層状気体流路５４を通って風路Ｇまで移動する間に、熱交換素子１１５の吸着剤５８に臭気成分が除去される。風路Ｇまで移動した外気は、さらに第２の風路切換弁１１４ｂによって構成される第２の給排気風路１１８を通って風路Ｈへ給気される。 As shown in FIG. 15, when the heat exchange unit 113 is the first air passage, that is, the first air passage switching valve 114a and the second air passage switching valve 114b are in the first switching state. In this case, the outside air, which is the airflow 56 taken into the vehicle ventilation device 10 from the outside of the vehicle and flows through the air passage A, contains an odor component. The outside air is blown from the air passage A through the first air supply / exhaust air passage 117 composed of the first air passage switching valve 114a, the air passage B, and the first layered gas flow path 54 of the heat exchange element 115. While moving to the path G, the odor component is removed by the adsorbent 58 of the heat exchange element 115. The outside air that has moved to the air passage G is further supplied to the air passage H through the second air supply / exhaust air passage 118 configured by the second air passage switching valve 114b.
　一方、熱交換部１１３の風路が第１の風路となっている場合、車内１０２から車両用換気装置１０に取り込まれて風路Ｄを流れる排気流５７である車内１０２の内気は、第２の風路切換弁１１４ｂによって構成される第２の給排気風路１１８、風路Ｃ、熱交換素子１１５の第２の層状気体流路５５、風路Ｆ、第１の風路切換弁１１４ａによって構成される第１の給排気風路１１７、風路Ｅを通って車外へ排気される。このとき、熱交換素子１１５の第１の層状気体流路５４を流れる外気と、熱交換素子１１５の第２の層状気体流路５５を流れる内気との間で熱交換がなされる。 On the other hand, when the air passage of the heat exchange unit 113 is the first air passage, the inside air of the vehicle interior 102, which is the exhaust flow 57 taken into the vehicle ventilation device 10 from the vehicle interior 102 and flows through the air passage D, is the first. The second air supply / exhaust air passage 118, the air passage C, the second layered gas flow path 55 of the heat exchange element 115, the air passage F, and the first air passage switching valve 114a, which are composed of the two air passage switching valves 114b. It is exhausted to the outside of the vehicle through the first air supply / exhaust air passage 117 and the air passage E composed of the above. At this time, heat exchange is performed between the outside air flowing through the first layered gas flow path 54 of the heat exchange element 115 and the inside air flowing through the second layered gas flow path 55 of the heat exchange element 115.
　吸着剤５８が添着された熱交換素子１１５は、吸着剤５８が物理吸着によって臭気成分を吸着除去する。吸着剤５８は、長期間の使用にともなって臭気成分の吸着能力が低下する。そして、吸着剤５８における臭気成分の吸着能力が低下した場合には、車内１０２に侵入する臭気成分が増加する。 In the heat exchange element 115 to which the adsorbent 58 is attached, the adsorbent 58 adsorbs and removes the odor component by physical adsorption. The adsorbent 58 has a reduced ability to adsorb odorous components with long-term use. Then, when the adsorbing ability of the odorous component in the adsorbent 58 decreases, the odorous component invading the vehicle interior 102 increases.
　そこで、車両用換気装置１０では、第１の給排気風路１１７および第２の給排気風路１１８を第１の風路と第２の風路との間で切り換える。車両用換気装置１０は、制御部２０１の制御により第１の風路切換弁１１４ａおよび第２の風路切換弁１１４ｂの隔壁開口部３３２の開閉を変更することにより、第１の風路切換弁１１４ａおよび第２の風路切換弁１１４ｂを第１の切換え状態または第２の切換え状態に切り換えることが可能である。すなわち、車両用換気装置１０は、制御部２０１の制御により第１の風路切換弁１１４ａおよび第２の風路切換弁１１４ｂの隔壁開口部３３２の開閉を変更することにより、第１の風路切換弁１１４ａおよび第２の風路切換弁１１４ｂを、第１の風路または第２の風路に切り換えることが可能である。 Therefore, in the vehicle ventilation device 10, the first air supply / exhaust air passage 117 and the second air supply / exhaust air passage 118 are switched between the first air passage and the second air passage. The vehicle ventilation device 10 changes the opening and closing of the partition wall opening 332 of the first air passage switching valve 114a and the second air passage switching valve 114b under the control of the control unit 201, thereby changing the opening and closing of the first air passage switching valve. It is possible to switch the 114a and the second air passage switching valve 114b to the first switching state or the second switching state. That is, the vehicle ventilation device 10 changes the opening and closing of the partition wall opening 332 of the first air passage switching valve 114a and the second air passage switching valve 114b under the control of the control unit 201, thereby changing the opening and closing of the first air passage. It is possible to switch the switching valve 114a and the second air passage switching valve 114b to the first air passage or the second air passage.
　図１６に示すように、熱交換部１１３の風路が第２の風路となっている場合、すなわち、第１の風路切換弁１１４ａおよび第２の風路切換弁１１４ｂが第２の切換え状態となっている場合、車外から車両用換気装置１０に取り込まれて風路Ａを流れる給気流５６である外気には臭気成分が含まれている。外気は、風路Ａから、第１の風路切換弁１１４ａによって構成される第１の給排気風路１１７、風路Ｆ、熱交換素子１１５の第２の層状気体流路５５を通って風路Ｃまで移動する。風路Ｃまで移動した外気は、さらに第２の風路切換弁１１４ｂによって構成される第２の給排気風路１１８を通って風路Ｈへ給気される。 As shown in FIG. 16, when the air passage of the heat exchange unit 113 is the second air passage, that is, the first air passage switching valve 114a and the second air passage switching valve 114b are the second switching. In this state, the outside air, which is the airflow 56 taken into the vehicle ventilation device 10 from the outside of the vehicle and flows through the air passage A, contains an odor component. The outside air is blown from the air passage A through the first air supply / exhaust air passage 117 composed of the first air passage switching valve 114a, the air passage F, and the second layered gas flow path 55 of the heat exchange element 115. Move to Road C. The outside air that has moved to the air passage C is further supplied to the air passage H through the second air supply / exhaust air passage 118 configured by the second air passage switching valve 114b.
　一方、熱交換部１１３の風路が第２の風路となっている場合、車内１０２から車両用換気装置１０に取り込まれて風路Ｄを流れる排気流５７である車内１０２の内気は、第２の風路切換弁１１４ｂによって構成される第２の給排気風路１１８、風路Ｇ、熱交換素子１１５の第１の層状気体流路５４、風路Ｂ、第１の風路切換弁１１４ａによって構成される第１の給排気風路１１７、風路Ｅを通って車外へ排気される。このとき、熱交換素子１１５の第１の層状気体流路５４を流れる外気と、熱交換素子１１５の第２の層状気体流路５５を流れる内気との間で熱交換がなされる。 On the other hand, when the air passage of the heat exchange unit 113 is the second air passage, the inside air of the vehicle interior 102, which is the exhaust flow 57 taken into the vehicle ventilation device 10 from the vehicle interior 102 and flows through the air passage D, is the second. The second air supply / exhaust air passage 118, the air passage G, the first layered gas flow path 54 of the heat exchange element 115, the air passage B, and the first air passage switching valve 114a, which are composed of the two air passage switching valves 114b. It is exhausted to the outside of the vehicle through the first air supply / exhaust air passage 117 and the air passage E composed of the above. At this time, heat exchange is performed between the outside air flowing through the first layered gas flow path 54 of the heat exchange element 115 and the inside air flowing through the second layered gas flow path 55 of the heat exchange element 115.
　熱交換部１１３の風路が第１の風路となっている場合、外気は、吸着剤５８が配置されている第１の層状気体流路５４を通過する。吸着剤５８は、第１の層状気体流路５４を通過する外気に含まれる臭気成分を吸着して外気から除去する。吸着剤５８に吸着された臭気成分は、徐々に吸着剤５８から脱着されて車内１０２へ排出される。 When the air passage of the heat exchange unit 113 is the first air passage, the outside air passes through the first layered gas flow path 54 in which the adsorbent 58 is arranged. The adsorbent 58 adsorbs the odorous component contained in the outside air passing through the first layered gas flow path 54 and removes it from the outside air. The odorous component adsorbed on the adsorbent 58 is gradually desorbed from the adsorbent 58 and discharged into the vehicle 102.
　一方、熱交換部１１３の風路を第２の風路に変更することにより、排気流５７が、吸着剤５８が配置されている第１の層状気体流路５４を、外気が第１の層状気体流路５４を通過する方向と逆の方向に通過する。これにより、通過する排気流５７に含まれる臭気成分と吸着剤５８に吸着濃縮されている臭気成分との濃度差が駆動力となり、吸着剤５８に吸着されている臭気成分の一部が脱着されて、排気流５７とともに車外に排出される。これにより、車両用換気装置１０は、第１の層状気体流路５４に配置された吸着剤５８に吸着されている臭気成分を低減させて、吸着剤５８における臭気成分の吸着容量を回復させることができる。 On the other hand, by changing the air passage of the heat exchange unit 113 to the second air passage, the exhaust flow 57 is in the first layered gas flow path 54 in which the adsorbent 58 is arranged, and the outside air is in the first layer. It passes in the direction opposite to the direction in which it passes through the gas flow path 54. As a result, the concentration difference between the odorous component contained in the passing exhaust flow 57 and the odorous component adsorbed and concentrated on the adsorbent 58 serves as a driving force, and a part of the odorous component adsorbed on the adsorbent 58 is desorbed. Then, it is discharged to the outside of the vehicle together with the exhaust flow 57. As a result, the vehicle ventilation device 10 reduces the odorous component adsorbed on the adsorbent 58 arranged in the first layered gas flow path 54, and restores the adsorbed capacity of the odorous component in the adsorbent 58. Can be done.
　熱交換部１１３の風路が第２の風路となっている場合、排気用送風機１１１ｂは、熱交換部１１３の風路が第１の風路となっているときと同じ運転をする。このため、第１の層状気体流路５４には、熱交換部１１３の風路が第１の風路となっているときと逆向きに排気流５７が流れるが、第１の層状気体流路５４を通過する排気流５７の風量は、熱交換部１１３の風路が第１の風路となっている場合と変わらない。したがって、たとえば第１の給気用送風機４または第２の給気用送風機１１１ａを逆回転させた場合に発生できる風量と比べて大きな風量が得られる。 When the air passage of the heat exchange unit 113 is the second air passage, the exhaust blower 111b operates in the same manner as when the air passage of the heat exchange unit 113 is the first air passage. Therefore, the exhaust flow 57 flows through the first layered gas flow path 54 in the opposite direction to that when the air passage of the heat exchange unit 113 is the first air passage, but the first layered gas flow path The air volume of the exhaust flow 57 passing through the 54 is the same as that in the case where the air passage of the heat exchange unit 113 is the first air passage. Therefore, for example, a larger air volume can be obtained as compared with the air volume that can be generated when the first air supply blower 4 or the second air supply blower 111a is rotated in the reverse direction.
　また、車両用換気装置１０は、熱交換部１１３の風路が第１の風路となっている場合と、熱交換部１１３の風路が第２の風路となっている場合との両方の場合において、車内１０２の換気を行うことができる。このため、吸着剤５８における臭気成分の吸着容量を回復させるために、車内１０２の換気が実施できないといったことが発生しない。 Further, in the vehicle ventilation device 10, both the case where the air passage of the heat exchange unit 113 is the first air passage and the case where the air passage of the heat exchange unit 113 is the second air passage. In the case of, the inside of the vehicle 102 can be ventilated. Therefore, in order to restore the adsorption capacity of the odorous component in the adsorbent 58, it does not occur that the inside of the vehicle 102 cannot be ventilated.
　また、吸着剤５８が第２の層状気体流路５５に配置されている場合には、熱交換部１１３の風路が第２の風路となっているときに、吸着剤５８が、第２の層状気体流路５５を通過する外気に含まれる臭気成分を吸着して外気から除去する。そして、熱交換部１１３の風路が第１の風路となっているときに、排気流５７が、吸着剤５８が配置されている第２の層状気体流路５５を、外気が第２の層状気体流路５５を通過する方向と逆の方向に通過する。これにより、通過する排気流５７に含まれる臭気成分と吸着剤５８に吸着濃縮されている臭気成分との濃度差が駆動力となり、吸着剤５８に吸着されている臭気成分の一部が脱着されて、排気流５７とともに車外に排出される。これにより、車両用換気装置１０は、第２の層状気体流路５５に配置された吸着剤５８に吸着されている臭気成分を低減させて、吸着剤５８における臭気成分の吸着容量を回復させることができる。 Further, when the adsorbent 58 is arranged in the second layered gas flow path 55, when the air passage of the heat exchange unit 113 is the second air passage, the adsorbent 58 is second. The odorous component contained in the outside air passing through the layered gas flow path 55 is adsorbed and removed from the outside air. Then, when the air passage of the heat exchange unit 113 is the first air passage, the exhaust flow 57 passes through the second layered gas flow path 55 in which the adsorbent 58 is arranged, and the outside air is second. It passes in the direction opposite to the direction in which it passes through the layered gas flow path 55. As a result, the concentration difference between the odorous component contained in the passing exhaust flow 57 and the odorous component adsorbed and concentrated on the adsorbent 58 serves as a driving force, and a part of the odorous component adsorbed on the adsorbent 58 is desorbed. Then, it is discharged to the outside of the vehicle together with the exhaust flow 57. As a result, the vehicle ventilation device 10 reduces the odorous component adsorbed on the adsorbent 58 arranged in the second layered gas flow path 55, and restores the adsorbed capacity of the odorous component in the adsorbent 58. Can be done.
　吸着剤５８が第２の層状気体流路５５に配置されている場合も、車両用換気装置１０は、熱交換部１１３の風路が第１の風路となっている場合と、熱交換部１１３の風路が第２の風路となっている場合との両方の場合において、車内１０２の換気を行うことができる。このため、吸着剤５８における臭気成分の吸着容量を回復させるために、車内１０２の換気が実施できないといったことが発生しない。 Even when the adsorbent 58 is arranged in the second layered gas flow path 55, the vehicle ventilation device 10 has a case where the air passage of the heat exchange unit 113 is the first air passage and a heat exchange unit. Ventilation of the vehicle interior 102 can be performed in both cases where the air passage 113 is the second air passage. Therefore, in order to restore the adsorption capacity of the odorous component in the adsorbent 58, it does not occur that the inside of the vehicle 102 cannot be ventilated.
　また、熱交換素子１１５における第１の層状気体流路５４と第２の層状気体流路５５との両方の風路に吸着剤５８を配置しておくことが好ましい。これにより、車両用換気装置１０は、熱交換部１１３の風路が第１の風路となっている場合および熱交換部１１３の風路が第２の風路となっている場合のいずれの場合においても、第１の層状気体流路５４と第２の層状気体流路５５とのうちの一方の風路において外気に含まれる臭気成分を吸着して外気から除去し、且つ第１の層状気体流路５４と第２の層状気体流路５５とのうちの他方の風路において吸着剤５８における臭気成分の吸着容量を回復させることができる。したがって、熱交換部１１３の風路を第１の風路と第２の風路との間で切り換えても外気に含まれる臭気成分を連続的に吸着除去しながら、車内１０２の換気が可能である。 Further, it is preferable to arrange the adsorbent 58 in both the air passages of the first layered gas flow path 54 and the second layered gas flow path 55 in the heat exchange element 115. As a result, in the vehicle ventilation device 10, either the case where the air passage of the heat exchange unit 113 is the first air passage or the case where the air passage of the heat exchange unit 113 is the second air passage. Even in this case, the odorous component contained in the outside air is adsorbed and removed from the outside air in one of the air passages of the first layered gas flow path 54 and the second layered gas flow path 55, and the first layered gas flow path is formed. The adsorption capacity of the odorous component in the adsorbent 58 can be restored in the other air passage of the gas flow path 54 and the second layered gas flow path 55. Therefore, even if the air passage of the heat exchange unit 113 is switched between the first air passage and the second air passage, it is possible to ventilate the inside of the vehicle 102 while continuously adsorbing and removing the odor component contained in the outside air. is there.
　したがって、車両用換気装置１０は、熱交換部１１３の風路を第１の風路と第２の風路との間で切り換えることで、車両用換気装置１０における給気風路２１および排気風路２２自体を切り換えることなく、且つ熱交換素子１１５を移動させることなく、熱交換素子１１５に対する給気流５６と排気流５７との逆方向にでき、車内の暖かい空気により吸着剤５８における臭気成分の脱着性能が向上し、吸着剤５８の吸着容量を回復することができる。 Therefore, the vehicle ventilation device 10 switches the air passage of the heat exchange unit 113 between the first air passage and the second air passage, whereby the air supply air passage 21 and the exhaust air passage in the vehicle ventilation device 10 are switched. The supply airflow 56 and the exhaust flow 57 with respect to the heat exchange element 115 can be formed in the opposite directions without switching the 22 itself and without moving the heat exchange element 115, and the odorous component in the adsorbent 58 is desorbed by the warm air in the vehicle. The performance is improved, and the adsorption capacity of the adsorbent 58 can be recovered.
　第１の風路と第２の風路との間での熱交換部１１３の風路変更、すなわち第１の風路切換弁１１４ａおよび第２の風路切換弁１１４ｂの隔壁開口部３３２の開閉の切り換えとしては、手動による風路変更、または自動風路変更がある。 Changing the air passage of the heat exchange unit 113 between the first air passage and the second air passage, that is, opening and closing the partition wall opening 332 of the first air passage switching valve 114a and the second air passage switching valve 114b. There are manual air passage change and automatic air passage change as switching between.
　手動による風路変更の場合は、乗務員が不快と感じた際に、スイッチ等を用いて第１の風路と第２の風路との間での熱交換部１１３の風路変更を行えばよい。すなわち、乗務員が不快と感じた際に、スイッチ等を用いて第１の風路切換弁１１４ａおよび第２の風路切換弁１１４ｂの隔壁開口部３３２の開閉を切り換えればよい。 In the case of manual air passage change, when the crew feels uncomfortable, the air passage of the heat exchange unit 113 between the first air passage and the second air passage can be changed by using a switch or the like. Good. That is, when the crew feels uncomfortable, the opening and closing of the partition wall opening 332 of the first air passage switching valve 114a and the second air passage switching valve 114b may be switched by using a switch or the like.
　また、自動風路変更の場合は、例えば、上流側給気風路２１１および上流側排気風路２２１にガスセンサ１５を配置し、各ガスセンサ１５の出力信号を制御部２０１へ送信し、出力信号の差分または出力信号から算出される臭気成分の濃度の差分により、第１の風路切換弁１１４ａおよび第２の風路切換弁１１４ｂの隔壁開口部３３２の開閉を制御部２０１が制御する。図１７は、本発明の実施の形態１にかかる車両用換気装置１０における空気中の臭気成分の濃度に基づいた熱交換部１１３の風路の自動切換制御の手順を示すフローチャートである。制御部２０１は、車両１００の外部に設置されて外気の臭気成分の濃度を検知する車外のガスセンサ１５と、車両１００の内部に配置されて車両１００の内気の臭気成分の濃度を検知する車内１０２のガスセンサ１５と、の検知結果の差分に基づいて、風路切換弁１１４を切り換えるタイミングを決定する。 Further, in the case of automatic air passage change, for example, gas sensors 15 are arranged in the upstream air supply air passage 211 and the upstream exhaust air passage 221 and the output signals of the gas sensors 15 are transmitted to the control unit 201 to make a difference between the output signals. Alternatively, the control unit 201 controls the opening and closing of the partition wall opening 332 of the first air passage switching valve 114a and the second air passage switching valve 114b by the difference in the concentration of the odor component calculated from the output signal. FIG. 17 is a flowchart showing a procedure of automatic switching control of the air passage of the heat exchange unit 113 based on the concentration of the odor component in the air in the vehicle ventilation device 10 according to the first embodiment of the present invention. The control unit 201 is installed outside the vehicle 100 to detect the concentration of the odor component of the outside air, and the gas sensor 15 outside the vehicle and is arranged inside the vehicle 100 to detect the concentration of the odor component of the inside air of the vehicle 100. The timing of switching the air passage switching valve 114 is determined based on the difference between the gas sensor 15 and the detection result of the above.
　ステップＳ１０において、制御部２０１がガスセンサ１５から臭気成分の検出結果の電気信号の出力を取得する。すなわち、車外のガスセンサ１５が、車外のガスセンサ１５で検出された外気における臭気成分である窒素酸化物の濃度に対応する大きさの電気信号を制御部２０１へ出力する。また、車内１０２のガスセンサ１５が、車内１０２のガスセンサ１５で検出された内気における臭気成分である窒素酸化物の濃度に対応する大きさの電気信号を制御部２０１へ出力する。車外のガスセンサ１５と車内１０２のガスセンサ１５とは、予め決められた周期で窒素酸化物の濃度を検出して、電気信号を制御部２０１へ送信する。なお、ここでは、臭気成分が窒素酸化物である場合を例に説明しているが、臭気成分が揮発性有機化合物である場合も、および臭気成分がその他の物質である場合においても、上記と同様にステップＳ１０が実施される。 In step S10, the control unit 201 acquires the output of the electric signal of the detection result of the odor component from the gas sensor 15. That is, the gas sensor 15 outside the vehicle outputs an electric signal having a magnitude corresponding to the concentration of nitrogen oxides, which is an odor component in the outside air, detected by the gas sensor 15 outside the vehicle to the control unit 201. Further, the gas sensor 15 in the vehicle interior 102 outputs an electric signal having a magnitude corresponding to the concentration of nitrogen oxides, which is an odor component in the inside air, detected by the gas sensor 15 in the vehicle interior 102 to the control unit 201. The gas sensor 15 outside the vehicle and the gas sensor 15 inside the vehicle 102 detect the concentration of nitrogen oxides at a predetermined cycle, and transmit an electric signal to the control unit 201. Here, the case where the odor component is a nitrogen oxide is described as an example, but the above applies even when the odor component is a volatile organic compound and the odor component is another substance. Similarly, step S10 is carried out.
　ステップＳ２０において、制御部２０１は、車外のガスセンサ１５から出力された電気信号と、車内１０２のガスセンサ１５から出力された電気信号との出力の差分である出力差分を算出する。 In step S20, the control unit 201 calculates the output difference, which is the difference between the outputs of the electric signal output from the gas sensor 15 outside the vehicle and the electric signal output from the gas sensor 15 inside the vehicle 102.
　ステップＳ３０において、制御部２０１は、予め決められた出力差分の閾値である第１の閾値と、算出した出力差分とを比較し、算出した出力差分が第１の閾値以下であるか否かを判定する。第１の閾値は、制御部２０１が車両用換気装置１０における風路を第１の風路と第２の風路とで切り換える風路切換制御を実施するか否かを判定するための、出力差分の閾値である。制御部２０１は、算出した出力差分が第１の閾値以下である場合には、熱交換素子１１５に配置された吸着剤５８における臭気成分の吸着能力が低下していると判定する。制御部２０１は、算出した出力差分が第１の閾値より大きい場合には、熱交換素子１１５に配置された吸着剤５８における臭気成分の吸着能力が低下していないと判定する。 In step S30, the control unit 201 compares the first threshold value, which is a predetermined output difference threshold value, with the calculated output difference, and determines whether or not the calculated output difference is equal to or less than the first threshold value. judge. The first threshold value is an output for determining whether or not the control unit 201 executes air passage switching control for switching the air passage in the vehicle ventilation device 10 between the first air passage and the second air passage. This is the threshold of the difference. When the calculated output difference is equal to or less than the first threshold value, the control unit 201 determines that the adsorbing ability of the odorous component in the adsorbent 58 arranged in the heat exchange element 115 is reduced. When the calculated output difference is larger than the first threshold value, the control unit 201 determines that the adsorbing ability of the odorous component in the adsorbent 58 arranged in the heat exchange element 115 has not decreased.
　算出した出力差分が第１の閾値より大きいと判定された場合は、ステップＳ３０においてＮｏとなり、ステップＳ２０に戻る。算出した出力差分が第１の閾値以下であると判定された場合は、ステップＳ３０においてＹｅｓとなり、ステップＳ４０に進む。 If it is determined that the calculated output difference is larger than the first threshold value, the result is No in step S30, and the process returns to step S20. If it is determined that the calculated output difference is equal to or less than the first threshold value, the result is Yes in step S30, and the process proceeds to step S40.
　ステップＳ４０において、制御部２０１は、車両用換気装置１０における風路を、第１の風路と第２の風路とで切り換える風路切換制御を実施する。すなわち、制御部２０１は、現在の車両用換気装置１０における風路が第１の風路である場合には、車両用換気装置１０における風路を第２の風路に切り換える制御を行う。また、制御部２０１は、現在の車両用換気装置１０における風路が第２の風路である場合には、車両用換気装置１０における風路を第１の風路に切り換える制御を行う。 In step S40, the control unit 201 performs air passage switching control for switching the air passage in the vehicle ventilation device 10 between the first air passage and the second air passage. That is, when the air passage in the current vehicle ventilation device 10 is the first air passage, the control unit 201 controls to switch the air passage in the vehicle ventilation device 10 to the second air passage. Further, when the air passage in the current vehicle ventilation device 10 is the second air passage, the control unit 201 controls to switch the air passage in the vehicle ventilation device 10 to the first air passage.
　以上の処理が実施されることにより、車両用換気装置１０では、車両用換気装置１０における風路の切換を自動で行うことができ、吸着剤５８の吸着容量を回復させることができる。この場合、上述したように熱交換素子１１５における第１の層状気体流路５４と第２の層状気体流路５５との両方の風路に吸着剤５８を配置しておくことが好ましい。 By performing the above processing, the vehicle ventilation device 10 can automatically switch the air passage in the vehicle ventilation device 10, and can recover the adsorption capacity of the adsorbent 58. In this case, as described above, it is preferable to dispose the adsorbent 58 in both the air passages of the first layered gas flow path 54 and the second layered gas flow path 55 in the heat exchange element 115.
　なお、上記においては、車外のガスセンサ１５と車内１０２のガスセンサ１５とが窒素酸化物の濃度を検出する場合について説明したが、車外のガスセンサ１５と車内１０２のガスセンサ１５とは、揮発性有機化合物の濃度を検出してもよく、窒素酸化物の濃度と揮発性有機化合物の濃度との両方を検出してもよい。この場合も、制御部２０１は、上述した手順によって、自動で車両用換気装置１０における熱交換部１１３の風路を切り換える制御を行うことができる。 In the above, the case where the gas sensor 15 outside the vehicle and the gas sensor 15 inside the vehicle 102 detect the concentration of nitrogen oxides has been described, but the gas sensor 15 outside the vehicle and the gas sensor 15 inside the vehicle 102 are volatile organic compounds. The concentration may be detected, or both the concentration of nitrogen oxides and the concentration of volatile organic compounds may be detected. In this case as well, the control unit 201 can automatically control the air passage of the heat exchange unit 113 in the vehicle ventilation device 10 by the above-mentioned procedure.
　また、制御部２０１は、車両１００に搭載されている走行距離メーター１０４における走行距離に基づいて、自動で熱交換部１１３の風路を切り換える制御を行ってもよい。図１８は、本発明の実施の形態１にかかる車両用換気装置１０における車両１００の走行距離に基づいた熱交換部１１３の風路の自動切換制御の手順を示すフローチャートである。制御部２０１は、前回に第１の切換え状態と第２の切換え状態とを切り換えた後の車両１００の走行距離に基づいて、風路切換弁１１４を切り換えるタイミングを決定する。 Further, the control unit 201 may automatically switch the air passage of the heat exchange unit 113 based on the mileage of the mileage meter 104 mounted on the vehicle 100. FIG. 18 is a flowchart showing a procedure for automatic switching control of the air passage of the heat exchange unit 113 based on the mileage of the vehicle 100 in the vehicle ventilation device 10 according to the first embodiment of the present invention. The control unit 201 determines the timing for switching the air passage switching valve 114 based on the mileage of the vehicle 100 after the previous switching between the first switching state and the second switching state.
　ステップＳ１１０において、制御部２０１は、車両１００に搭載されている走行距離メーター１０４から車両１００の現在の走行距離を取得する。また、制御部２０１は、前回に自動で車両用換気装置１０における風路を切り換えた際の車両１００の走行距離を記憶している。 In step S110, the control unit 201 acquires the current mileage of the vehicle 100 from the mileage meter 104 mounted on the vehicle 100. Further, the control unit 201 stores the mileage of the vehicle 100 when the air passage in the vehicle ventilation device 10 was automatically switched last time.
　ステップＳ１２０において、制御部２０１は、前回に自動で熱交換部１１３の風路を切り換えた際の走行距離と、現在の走行距離と、の差分である走行距離の差分を算出する。走行距離の差分は、前回に自動で熱交換部１１３の風路を切り換えた後の車両１００の走行距離である。 In step S120, the control unit 201 calculates the difference in mileage, which is the difference between the mileage when the air passage of the heat exchange unit 113 was automatically switched last time and the current mileage. The difference in the mileage is the mileage of the vehicle 100 after the air passage of the heat exchange unit 113 was automatically switched last time.
　ステップＳ１３０において、制御部２０１は、算出した走行距離の差分と、予め決められた走行距離の差分の閾値である第２の閾値とを比較し、算出した走行距離の差分が第２の閾値以上であるか否かを判定する。第２の閾値は、制御部２０１が熱交換部１１３の風路を第１の風路と第２の風路との間で切り換える風路切換制御を実施するか否かを判定するための、走行距離の差分の閾値である。制御部２０１は、算出した走行距離の差分が第２の閾値以上である場合には、熱交換素子１１５に配置された吸着剤５８における臭気成分の吸着能力が低下していると判定する。制御部２０１は、算出した走行距離の差分が第２の閾値より小さい場合には、熱交換素子１１５に配置された吸着剤５８における臭気成分の吸着能力が低下していないと判定する。 In step S130, the control unit 201 compares the calculated difference in mileage with the second threshold value which is the threshold value of the difference in mileage determined in advance, and the difference in the calculated mileage is equal to or greater than the second threshold value. It is determined whether or not it is. The second threshold value is for determining whether or not the control unit 201 executes the air passage switching control for switching the air passage of the heat exchange unit 113 between the first air passage and the second air passage. This is the threshold value for the difference in mileage. When the difference in the calculated mileage is equal to or greater than the second threshold value, the control unit 201 determines that the adsorbing ability of the odorous component in the adsorbent 58 arranged in the heat exchange element 115 is reduced. When the difference in the calculated mileage is smaller than the second threshold value, the control unit 201 determines that the adsorbing ability of the odor component in the adsorbent 58 arranged in the heat exchange element 115 has not decreased.
　算出した出力差分が第２の閾値より小さいと判定された場合は、ステップＳ１３０においてＮｏとなり、ステップＳ１２０に戻る。算出した出力差分が第２の閾値以上であると判定された場合は、ステップＳ１３０においてＹｅｓとなり、ステップＳ１４０に進む。 If it is determined that the calculated output difference is smaller than the second threshold value, the result becomes No in step S130, and the process returns to step S120. If it is determined that the calculated output difference is equal to or greater than the second threshold value, the result is Yes in step S130, and the process proceeds to step S140.
　ステップＳ１４０は、上述したステップＳ４０と同様である。 Step S140 is the same as step S40 described above.
　以上の処理が実施されることにより、車両用換気装置１０では、熱交換部１１３の風路の切換を自動で行うことができ、吸着剤５８の吸着容量を回復させることができる。 By performing the above processing, the vehicle ventilation device 10 can automatically switch the air passage of the heat exchange unit 113, and can recover the adsorption capacity of the adsorbent 58.
　つぎに、車両用換気装置１０において内気合流風路２３と外気合流風路２４とを閉じた外気熱交換モードでの、給気風路２１と排気風路２２とを説明する。制御部２０１の制御によって行われる車両用空気調和換気装置２０の空気調和および換気の種類には、空気の流れの異なる４種類のモードがある。具体的には、内外気混合モードと、外気モードと、内気モードと、外気熱交換モードである。外気が導入される外気熱交換モードでは、制御部２０１は、第１の開度調整部１２８を制御して、内気合流風路２３を閉鎖する位置に第１の開度調整部１２８を配置する。また、制御部２０１は、第２の開度調整部１２９を制御して、外気合流風路２４を塞ぐ位置に第２の開度調整部１２９を配置する。また、制御部２０１は、第１の給気用送風機４、第２の給気用送風機１１１ａおよび排気用送風機１１１ｂを駆動させる。 Next, the air supply air passage 21 and the exhaust air passage 22 in the outside air heat exchange mode in which the inside air confluence air passage 23 and the outside air confluence air passage 24 are closed in the vehicle ventilation device 10 will be described. There are four types of air conditioning and ventilation of the vehicle air conditioning ventilation device 20 controlled by the control unit 201, which have different air flows. Specifically, there are an inside / outside air mixing mode, an outside air mode, an inside air mode, and an outside air heat exchange mode. In the outside air heat exchange mode in which the outside air is introduced, the control unit 201 controls the first opening degree adjusting unit 128 and arranges the first opening degree adjusting unit 128 at a position where the inside air confluence air passage 23 is closed. .. Further, the control unit 201 controls the second opening degree adjusting unit 129, and arranges the second opening degree adjusting unit 129 at a position that closes the outside air confluence air passage 24. Further, the control unit 201 drives the first air supply blower 4, the second air supply blower 111a, and the exhaust blower 111b.
　給気風路２１では、車外から、給気用車外開口１２１、第２の給気用送風機１１１ａ、第１の風路切換弁１１４ａ、熱交換素子１１５、第２の風路切換弁１１４ｂ、第１の給気用送風機４、冷却器５、加熱器６、車内給気口１４２、車内１０２の順に空気が流れる。 In the air supply air passage 21, from the outside of the vehicle, the air supply outside opening 121, the second air supply blower 111a, the first air passage switching valve 114a, the heat exchange element 115, the second air passage switching valve 114b, the first Air flows in the order of the air supply blower 4, the cooler 5, the heater 6, the in-vehicle air supply port 142, and the in-vehicle 102.
　排気風路２２では、車内１０２から、排気用車内開口１２４、第２の風路切換弁１１４ｂ、熱交換素子１１５、第１の風路切換弁１１４ａ、排気用送風機１１１ｂ、排気用車外開口１２２、車外の順に空気が流れる。 In the exhaust air passage 22, from the inside of the vehicle 102, the exhaust vehicle interior opening 124, the second air passage switching valve 114b, the heat exchange element 115, the first air passage switching valve 114a, the exhaust blower 111b, the exhaust vehicle exterior opening 122, Air flows in the order outside the vehicle.
　そして、外気熱交換モードにおいて、制御部２０１は、上述したように第１の風路切換弁１１４ａおよび第２の風路切換弁１１４ｂの隔壁開口部３３２の開閉状態を切り換えることにより、給気流５６および排気流５７の熱交換素子１１５への通気方向を変えて、第１の切換え状態と第２の切換え状態とを切り換えることができる。すなわち、制御部２０１は、第１の風路切換弁１１４ａと第２の風路切換弁１１４ｂの隔壁開口部３３２の開閉状態を切り換えることにより、熱交換部１１３の風路を第１の風路と第２の風路との間で切り換え、熱交換素子１１５の内部の風路を切り換えることができる。 Then, in the outside air heat exchange mode, the control unit 201 switches the open / closed state of the partition wall opening 332 of the first air passage switching valve 114a and the second air passage switching valve 114b as described above, so that the air supply airflow 56 The first switching state and the second switching state can be switched by changing the ventilation direction of the exhaust flow 57 to the heat exchange element 115. That is, the control unit 201 switches the open / closed state of the partition wall opening 332 of the first air passage switching valve 114a and the second air passage switching valve 114b to change the air passage of the heat exchange unit 113 to the first air passage. It is possible to switch between the air passage and the second air passage to switch the air passage inside the heat exchange element 115.
　ここで、車両用空気調和換気装置２０では、給気風路２１および排気風路２２における熱交換素子１１５の前後に、すなわち給気風路２１および排気風路２２における熱交換素子１１５の上流側と下流側とに、風路切換弁１１４により構成される給排気風路を備える。このため、車両用空気調和換気装置２０では、第１の給排気風路１１７と第２の給排気風路１１８とを固定したまま、熱交換素子１１５の内部の風路を切り換えることができる。 Here, in the vehicle air-conditioning ventilation device 20, before and after the heat exchange elements 115 in the air supply air passage 21 and the exhaust air passage 22, that is, upstream and downstream of the heat exchange elements 115 in the air supply air passage 21 and the exhaust air passage 22. An air supply / exhaust air passage composed of an air passage switching valve 114 is provided on the side. Therefore, in the vehicle air-conditioned ventilation device 20, the air passage inside the heat exchange element 115 can be switched while the first air supply / exhaust air passage 117 and the second air supply / exhaust air passage 118 are fixed.
　また、外気熱交換モードでは、熱交換素子１１５を通過した後の給気流５６への内気および外気の混合がなされない。したがって、外気熱交換モードでは、熱交換素子１１５での熱交換によって暖房運転時の空気調和負荷の低減が図られる。 Further, in the outside air heat exchange mode, the inside air and the outside air are not mixed with the supply airflow 56 after passing through the heat exchange element 115. Therefore, in the outside air heat exchange mode, the air conditioning load during the heating operation can be reduced by heat exchange with the heat exchange element 115.
　図１９および図２０に、車両用空気調和換気装置２０に臭気を含む外気を給気した際の熱交換素子１１５による臭気除去を説明するための概念図を示す。図１９は、本発明の実施の形態１にかかる車両用空気調和換気装置２０の上流側給気風路２１１における給気流５６である外気に含まれる有機物量と時間との関係を示す特性図である。図２０は、本発明の実施の形態１にかかる車両用空気調和換気装置２０の下流側給気風路２１２における給気流５６に含まれる有機物量と時間との関係を示す特性図である。 19 and 20 show conceptual diagrams for explaining the removal of odor by the heat exchange element 115 when the vehicle air-conditioned ventilation device 20 is supplied with outside air containing odor.

SS4 is the amount of organic matter at time T4. SS5 is the amount of organic matter at time T5. SS6 is the amount of organic matter at time T6. SS7 is the amount of organic matter at time T7.
　臭気を含む外気が上流側給気風路２１１に流入したとき、熱交換素子１１５で外気に含まれる臭気成分である有機物が、熱交換素子１１５に配置された吸着剤５８に吸着される。これにより、下流側給気風路２１２を流れる給気流５６では、有機物量は減少する。吸着剤５８に吸着された有機物は、徐々に吸着剤５８から脱着されて車内１０２へ排出される。 When the outside air containing odor flows into the upstream air supply air passage 211, the organic matter which is an odor component contained in the outside air is adsorbed by the adsorbent 58 arranged in the heat exchange element 115 by the heat exchange element 115. As a result, the amount of organic matter is reduced in the airflow 56 flowing through the downstream air supply air passage 212. The organic matter adsorbed on the adsorbent 58 is gradually desorbed from the adsorbent 58 and discharged into the vehicle 102.
　時間の間隔を空けて臭気を含む外気が上流側給気風路２１１に流入した場合、下流側給気風路２１２を流れる給気流５６では、有機物量が平均化される。例えば、時刻Ｔ２、時刻Ｔ４および時刻Ｔ６に、臭気を含む外気が上流側給気風路２１１に流入した場合、ＳＯ２＞ＳＳ２、ＳＯ３＜ＳＳ３、ＳＯ４＞ＳＳ４、ＳＯ５＜ＳＳ５、ＳＯ６＞ＳＳ６、ＳＯ７＜ＳＳ７となる。 When outside air containing odor flows into the upstream air supply air passage 211 at intervals of time, the amount of organic matter is averaged in the air flow 56 flowing through the downstream air supply air passage 212. For example, when outside air containing odor flows into the upstream air supply air passage 211 at time T2, time T4, and time T6, SO2> SS2, SO3 <SS3, SO4> SS4, SO5 <SS5, SO6> SS6, SO7 < It becomes SS7.
　熱交換素子１１５の吸着剤５８において、臭気成分である有機物の吸着量は、徐々に蓄積され、時間とともに増加する。すなわち、上流側給気風路２１１に臭気が流入しない状態での下流側給気風路２１２を流れる給気流５６に含まれる有機物量は徐々に増加し、車内１０２に流れる給気流５６の臭気量は徐々に増加する。したがって、ＳＳ３＜ＳＳ５＜ＳＳ７となる。ここで、下流側給気風路２１２を流れる給気流５６に含まれる有機物量が閾値レベルＳＬを超えると、車内１０２の人が不快感を抱くことになる。 In the adsorbent 58 of the heat exchange element 115, the adsorbed amount of the organic substance which is an odor component is gradually accumulated and increases with time. That is, the amount of organic matter contained in the air flow 56 flowing through the downstream air supply air passage 212 in a state where the odor does not flow into the upstream air supply air passage 211 gradually increases, and the odor amount of the air supply air 56 flowing through the vehicle interior 102 gradually increases. Increase to. Therefore, SS3 <SS5 <SS7. Here, if the amount of organic matter contained in the air flow 56 flowing through the downstream air supply air passage 212 exceeds the threshold level SL, the person in the vehicle 102 will feel uncomfortable.
　車両用空気調和換気装置２０では、閾値レベルＳＬを超えないように、熱交換部１１３の風路を第１の風路と第２の風路との間で定期的に切り換える。熱交換部１１３の風路が第１の風路である場合、熱交換素子１１５の第１の層状気体流路５４に配置された吸着剤５８に有機物が吸着される。熱交換部１１３の風路が第２の風路である場合、吸着剤５８に吸着された有機物は排気流５７により脱着排気され、減少する。 In the vehicle air-conditioned ventilation device 20, the air passage of the heat exchange unit 113 is periodically switched between the first air passage and the second air passage so as not to exceed the threshold level SL. When the air passage of the heat exchange unit 113 is the first air passage, the organic substance is adsorbed by the adsorbent 58 arranged in the first layered gas flow path 54 of the heat exchange element 115. When the air passage of the heat exchange unit 113 is the second air passage, the organic matter adsorbed on the adsorbent 58 is desorbed and exhausted by the exhaust flow 57, and the amount is reduced.
　このように、車両用空気調和換気装置２０では、給気流５６である外気に含まれる臭気成分を熱交換素子１１５の吸着剤５８に吸着させて除去して車内１０２に供給するとともに、熱交換部１１３の風路を第１の風路と第２の風路との間で定期的に切り換えることによって、吸着剤５８に吸着した臭気成分を車外に排出することで、外気に含まれる臭気成分に起因した給気流５６による車内１０２の不快感を抑制することができる。 As described above, in the vehicle air-conditioning ventilation device 20, the odor component contained in the outside air, which is the air supply 56, is adsorbed by the adsorbent 58 of the heat exchange element 115 to be removed and supplied to the vehicle interior 102, and the heat exchange unit is provided. By periodically switching the air passage of 113 between the first air passage and the second air passage, the odor component adsorbed on the adsorbent 58 is discharged to the outside of the vehicle, thereby becoming the odor component contained in the outside air. It is possible to suppress the discomfort of the vehicle interior 102 due to the resulting air supply 56.

Such recording media include one or more of non-volatile or volatile semiconductor memories, magnetic disks, flexible memories, optical disks, compact disks, and DVDs (Digital Versailles Disc).
　上述したように、本実施の形態１にかかる車両用空気調和換気装置２０では、熱交換部１１３の風路を第１の風路と第２の風路との間で切り換えることができる。このため、車両用空気調和換気装置２０では、給気流５６である外気に含まれる臭気成分を熱交換素子１１５の吸着剤５８に吸着させて除去して車内１０２に供給するとともに、吸着剤５８に吸着した臭気成分を車外に排出することができる。そして、外気に含まれる臭気成分に起因した給気流５６による車内１０２の不快感を抑制することができる。これにより、車両用空気調和換気装置２０では、車内１０２の不快感を抑制するとともに、吸着剤５８における臭気成分の吸着容量を回復させることができ、長期間にわたって吸着剤５８を使用可能である。 As described above, in the vehicle air-conditioned ventilation device 20 according to the first embodiment, the air passage of the heat exchange unit 113 can be switched between the first air passage and the second air passage. Therefore, in the vehicle air-conditioning ventilation device 20, the odor component contained in the outside air, which is the air flow 56, is adsorbed by the adsorbent 58 of the heat exchange element 115 to be removed and supplied to the vehicle interior 102, and is also supplied to the adsorbent 58. The adsorbed odor component can be discharged to the outside of the vehicle. Then, it is possible to suppress the discomfort of the vehicle interior 102 due to the air flow 56 caused by the odor component contained in the outside air. As a result, the vehicle air-conditioned ventilation device 20 can suppress the discomfort of the vehicle interior 102 and restore the adsorption capacity of the odorous component in the adsorbent 58, so that the adsorbent 58 can be used for a long period of time.
　これにより、車両用空気調和換気装置２０では、車内１０２の空気清浄化およびフロントガラス１０１の防曇対策となる車内１０２の換気において、熱交換素子１１５による熱交換を利用して給気流５６を暖めることができ、暖房負荷を電気から得る電気自動車における空気調和負荷低減を実現できる。 As a result, in the vehicle air-conditioning ventilation device 20, the air supply air 56 is warmed by utilizing heat exchange by the heat exchange element 115 in the ventilation of the vehicle interior 102, which is an air purification measure for the vehicle interior 102 and an antifogging measure for the front glass 101. This makes it possible to reduce the air-conditioning load in an electric vehicle in which the heating load is obtained from electricity.
　また、車両用空気調和換気装置２０は、車内１０２への外気の導入時に問題となる臭気成分の車内１０２への侵入を抑制することができる。 Further, the vehicle air-conditioned ventilation device 20 can suppress the invasion of the odor component into the vehicle interior 102, which is a problem when the outside air is introduced into the vehicle interior 102.
　また、車両用空気調和換気装置２０は、予め決められた周期間隔で、または任意の間隔で、熱交換部１１３の風路の第１の風路と第２の風路との間での切り換えを実施することにより、熱交換素子１１５の吸着剤５８における臭気成分の吸着と脱着とを繰り返し実施することができ、臭気成分が吸着した吸着剤５８の吸着容量を回復させることができる。これにより、車両用空気調和換気装置２０は、吸着剤５８の長寿命化を図ることができる。なお、吸着剤５８の寿命とは、臭気成分の吸着容量が予め決められた基準以上である状態に回復できる状態にある時間長さであり、臭気成分の脱着により予め決められた基準以上の臭気成分を吸着除去できる状態にある時間長さである。 Further, the vehicle air-conditioning ventilation device 20 switches the air passage of the heat exchange unit 113 between the first air passage and the second air passage at a predetermined periodic interval or at an arbitrary interval. By carrying out the above, the adsorption and desorption of the odorous component in the adsorbent 58 of the heat exchange element 115 can be repeatedly carried out, and the adsorption capacity of the adsorbent 58 to which the odorous component is adsorbed can be recovered. As a result, the vehicle air-conditioned ventilation device 20 can extend the life of the adsorbent 58. The life of the adsorbent 58 is the length of time during which the adsorption capacity of the odorous component can be restored to a state of being equal to or higher than a predetermined standard, and the odor is equal to or higher than the predetermined standard due to the desorption of the odorous component. It is the length of time that the component can be adsorbed and removed.
　したがって、本実施の形態１にかかる車両用空気調和換気装置２０および車両用換気装置１０は、車両１００の空気調和負荷を低減しつつ、長期間にわたって臭気成分の吸着性を維持して換気が可能である、という効果を奏する。 Therefore, the vehicle air-conditioning ventilation device 20 and the vehicle ventilation device 10 according to the first embodiment can ventilate while maintaining the adsorptivity of the odor component for a long period of time while reducing the air-conditioning load of the vehicle 100. It has the effect of being.
実施の形態２．
　本実施の形態２では、車両１００が車両用ナビゲーション装置４００を備える場合について説明する。図２３は、本発明の実施の形態２における車両用換気装置１０と車両用ナビゲーション装置４００との機能構成を示す図である。車両用換気装置１０と車両用ナビゲーション装置４００とは通信可能である。制御部２０１は、車両用ナビゲーション装置４００からの出力信号に基づいて、車両用換気装置１０を制御する。すなわち、制御部２０１は、後述するように、地理的位置情報と、地理的位置情報により特定される地点の空気に含まれる臭気成分量の情報である臭気成分量情報と、が関連付けられた臭気情報に基づいて、風路切換弁１１４を切り換えるタイミングを決定する。 Embodiment 2.
In the second embodiment, the case where the vehicle 100 includes the vehicle navigation device 400 will be described. FIG. 23 is a diagram showing a functional configuration of the vehicle ventilation device 10 and the vehicle navigation device 400 according to the second embodiment of the present invention. The vehicle ventilation device 10 and the vehicle navigation device 400 can communicate with each other. The control unit 201 controls the vehicle ventilation device 10 based on the output signal from the vehicle navigation device 400. That is, as will be described later, the control unit 201 has an odor associated with the geographical position information and the odor component amount information which is the information of the odor component amount contained in the air at the point specified by the geographical position information. Based on the information, the timing for switching the air passage switching valve 114 is determined.
　車両用ナビゲーション装置４００を利用した車両用換気装置１０の具体的な制御例について説明する。車両用ナビゲーション装置４００は、車両１００のナビゲーション制御に用いられる地図情報が記憶された地図データベース４０１と、車両用換気装置１０と通信を行うナビゲーション通信部４０２と、ユーザから車両用ナビゲーション装置４００に入力される地理情報と、地図データベース４０１に記憶された地図情報とを用いて車両１００のナビゲーション制御を行うナビゲーション制御部４０３と、を備える。 A specific control example of the vehicle ventilation device 10 using the vehicle navigation device 400 will be described. The vehicle navigation device 400 is input to the vehicle navigation device 400 by the user, the map database 401 that stores the map information used for the navigation control of the vehicle 100, the navigation communication unit 402 that communicates with the vehicle ventilation device 10. The navigation control unit 403 that controls the navigation of the vehicle 100 by using the geographic information to be generated and the map information stored in the map database 401 is provided.
　地図データベース４０１には、地理的位置情報と臭気成分量情報とが関連付けられた臭気情報が、記憶されている。臭気成分量情報は、ある地点の空気に含まれる臭気成分量の情報である。例えば、トンネル内は空気に含まれる臭気成分量が多くなり、臭気が強くなる。また、郊外よりも市街部の方が、空気に含まれる臭気成分量が多くなり、臭気が強くなる。また、熱交換素子１１５においては、第１の層状気体流路５４に吸着剤５８が配置されている。 The map database 401 stores odor information in which geographical location information and odor component amount information are associated with each other. The odor component amount information is information on the odor component amount contained in the air at a certain point. For example, the amount of odorous components contained in the air increases in the tunnel, and the odor becomes stronger. In addition, the amount of odorous components contained in the air is larger in the urban area than in the suburbs, and the odor becomes stronger. Further, in the heat exchange element 115, the adsorbent 58 is arranged in the first layered gas flow path 54.
　車両１００が、車両用ナビゲーション装置４００に設定された走行ルートに従ってナビゲーション走行する際に、制御部２０１は、予め決められた周期で車両用ナビゲーション装置４００の地図データベース４０１から、臭気情報を取得する。車両用ナビゲーション装置４００のナビゲーション制御部４０３は、ナビゲーション通信部４０２と車両用換気装置１０の通信部２０４とを介して、制御部２０１に臭気情報を送信する。 When the vehicle 100 navigates according to the travel route set in the vehicle navigation device 400, the control unit 201 acquires odor information from the map database 401 of the vehicle navigation device 400 at a predetermined cycle. The navigation control unit 403 of the vehicle navigation device 400 transmits odor information to the control unit 201 via the navigation communication unit 402 and the communication unit 204 of the vehicle ventilation device 10.
　制御部２０１は、臭気情報に基づいて空気に含まれる臭気成分量が多くなると予測される地域を通行する際には、熱交換部１１３の風路を第１の風路とする。これにより、熱交換素子１１５の風路は、給気流５６が第１の層状気体流路５４を流れるとともに排気流５７が第２の層状気体流路５５を流れる状態となる。この状態で車両用換気装置１０が外気熱交換モードで運転することにより、第１の層状気体流路５４に配置された吸着剤５８に臭気成分が効果的に吸着される。 The control unit 201 uses the air passage of the heat exchange unit 113 as the first air passage when passing through an area where the amount of odor components contained in the air is expected to increase based on the odor information. As a result, the air passage of the heat exchange element 115 is in a state in which the supply airflow 56 flows through the first layered gas flow path 54 and the exhaust flow 57 flows through the second layered gas flow path 55. By operating the vehicle ventilation device 10 in the outside air heat exchange mode in this state, the odor component is effectively adsorbed on the adsorbent 58 arranged in the first layered gas flow path 54.
　一方、制御部２０１は、臭気情報に基づいて空気に含まれる臭気成分量が少なくなると予想される地域を通行する際には、熱交換部１１３の風路を第２の風路とする。これにより、熱交換素子１１５の風路は、排気流５７が第１の層状気体流路５４を流れるとともに給気流５６が第２の層状気体流路５５を流れる状態となる。この状態で車両用換気装置１０が外気熱交換モードで運転することにより、第１の層状気体流路５４に配置された吸着剤５８から脱着した臭気成分が、排気流５７と共に車外に排出される。 On the other hand, the control unit 201 uses the air passage of the heat exchange unit 113 as the second air passage when passing through an area where the amount of odor components contained in the air is expected to decrease based on the odor information. As a result, the air passage of the heat exchange element 115 is in a state in which the exhaust flow 57 flows through the first layered gas flow path 54 and the supply air flow 56 flows through the second layered gas flow path 55. When the vehicle ventilation device 10 operates in the outside air heat exchange mode in this state, the odor component desorbed from the adsorbent 58 arranged in the first layered gas flow path 54 is discharged to the outside of the vehicle together with the exhaust flow 57. ..
　自動車の周辺の空気に含まれる臭気成分の主要因は、他の自動車が排出する排気ガスである。特に、トンネル内では、自動車から排出された排気ガスが周囲の大気中に拡散されにくい。このため、トンネル内の空気中の臭気成分濃度は、高くなる傾向にある。そして、トンネル内では、車内への臭気成分の流入が増加する傾向がある。そこで、例えば、車両１００がトンネルに入る前に熱交換部１１３の風路を第１の風路に切換え、トンネルから出た時点で熱交換部１１３の風路を第２の風路に切り換えることにより、臭気成分による車内１０２の不快感を抑制するとともに吸着剤５８に吸着された臭気成分を車外に排出することができる。 The main factor of the odor component contained in the air around the automobile is the exhaust gas emitted by other automobiles. In particular, in a tunnel, the exhaust gas discharged from an automobile is unlikely to be diffused into the surrounding atmosphere. Therefore, the concentration of odorous components in the air in the tunnel tends to be high. Then, in the tunnel, the inflow of odorous components into the vehicle tends to increase. Therefore, for example, the air passage of the heat exchange unit 113 is switched to the first air passage before the vehicle 100 enters the tunnel, and the air passage of the heat exchange unit 113 is switched to the second air passage when the vehicle 100 exits the tunnel. As a result, the discomfort of the vehicle interior 102 due to the odor component can be suppressed, and the odor component adsorbed by the adsorbent 58 can be discharged to the outside of the vehicle.
　市街地と郊外を比較すると、郊外よりも市街地のほうが自動車の交通量が多く、走行する自動車の数量が多い。このため、郊外よりも市街地のほうが、排気ガスにより大気中の臭気成分濃度が高くなる傾向にある。そして、郊外よりも市街地のほうが、車内への臭気成分の流入が、増加する傾向がある。そこで、また、車両１００が市街部から郊外に移動する際には、郊外で熱交換部１１３の風路を第２の風路に切り換える。これにより、市街部で第１の層状気体流路５４に配置された吸着剤５８に吸着された臭気成分を脱着させて、排気流５７と共に車外に排出することができる。 Comparing the urban area and the suburbs, the traffic volume of automobiles is heavier in the urban area than in the suburbs, and the number of automobiles traveling is larger. For this reason, the concentration of odorous components in the atmosphere tends to be higher due to exhaust gas in urban areas than in suburbs. And, the inflow of odorous components into the car tends to increase in the urban area than in the suburbs. Therefore, when the vehicle 100 moves from the urban area to the suburbs, the air passage of the heat exchange unit 113 is switched to the second air passage in the suburbs. As a result, the odorous component adsorbed on the adsorbent 58 arranged in the first layered gas flow path 54 in the urban area can be desorbed and discharged to the outside of the vehicle together with the exhaust flow 57.
　なお、第２の層状気体流路５５に吸着剤５８が配置されている場合は、上記において第１の風路と第２の風路とを入れ替えた制御が行われることにより、上記と同様の効果が得られる。 When the adsorbent 58 is arranged in the second layered gas flow path 55, the same as above is performed by controlling the first air passage and the second air passage to be exchanged in the above. The effect is obtained.
　また、第１の層状気体流路５４および第２の層状気体流路５５の両方に吸着剤５８が配置されている場合は、上記の制御、または上記において第１の風路と第２の風路とを入れ替えた制御が行われることにより、第１の層状気体流路５４に配置された吸着剤５８と、第２の層状気体流路５５に配置された吸着剤５８とに、交互に臭気成分を吸着させるとともに、交互に臭気成分を脱着させて車外に排出することができる。 Further, when the adsorbent 58 is arranged in both the first layered gas flow path 54 and the second layered gas flow path 55, the above control, or the first air passage and the second wind in the above. By performing control in which the paths are exchanged, the adsorbent 58 arranged in the first layered gas flow path 54 and the adsorbent 58 arranged in the second layered gas flow path 55 alternately have an odor. While adsorbing the components, the odorous components can be alternately desorbed and discharged to the outside of the vehicle.
　以下、熱交換部１１３の風路を第１の風路と第２の風路とで切り換えることによる効果について説明する。図２４から図２７に、熱交換部１１３の風路を第１の風路と第２の風路とで切り換えない場合の、車両用空気調和換気装置２０に臭気を含む外気を給気した際の熱交換素子１１５による臭気除去を説明するための概念図を示す。図２４は、本発明の実施の形態２にかかる臭気成分量情報における外気に含まれる有機物量と時間との関係を示す特性図である。図２５は、本発明の実施の形態２にかかる車両用空気調和換気装置２０の上流側給気風路２１１における給気流５６である外気に含まれる有機物量と時間との関係を示す特性図である。図２６は、本発明の実施の形態２にかかる車両用空気調和換気装置２０の下流側給気風路２１２における給気流５６に含まれる有機物量と時間との関係を示す特性図である。図２７は、本発明の実施の形態２にかかる車両用空気調和換気装置２０の下流側排気風路２２２における排気流５７に含まれる有機物量と時間との関係を示す特性図である。 Hereinafter, the effect of switching the air passage of the heat exchange unit 113 between the first air passage and the second air passage will be described. From FIG. 24 to FIG. 27, when the air-conditioned ventilation device 20 for a vehicle is supplied with outside air containing odor when the air passage of the heat exchange unit 113 is not switched between the first air passage and the second air passage. A conceptual diagram for explaining the removal of odor by the heat exchange element 115 of the above is shown.

FIG. 25 is a characteristic diagram showing the relationship between the amount of organic matter contained in the outside air, which is the airflow 56 in the upstream air-conditioned air passage 211 of the vehicle air-conditioned ventilation device 20 according to the second embodiment of the present invention, and time. ..

　車両１００が、車両用ナビゲーション装置４００で指定される走行ルートに従って走行し、時刻Ｔ１１から時刻Ｔ１２でトンネルを通過する。トンネル内は空気に含まれる臭気成分量が多くなり、図２４に示すように臭気成分量情報における外気に含まれる有機物量が多くなる。このとき、外気に含まれる有機物量が増加するので、図２５に示すように給気流５６に含まれる有機物量も増加する。 The vehicle 100 travels according to the travel route specified by the vehicle navigation device 400, and passes through the tunnel from time T11 to time T12. The amount of odorous components contained in the air increases in the tunnel, and as shown in FIG. 24, the amount of organic substances contained in the outside air in the odorous component amount information increases. At this time, since the amount of organic matter contained in the outside air increases, the amount of organic matter contained in the airflow 56 also increases as shown in FIG. 25.
　そして、熱交換素子１１５で外気に含まれる有機物が、熱交換素子１１５に配置された吸着剤５８に吸着される。これにより、図２６に示すように下流側給気風路２１２を流れる給気流５６に含まれる有機物量は、外気に含まれる有機物量に比べて減少する。そして、吸着剤５８に吸着された有機物は、時刻Ｔ１２以降に徐々に吸着剤５８から脱着されて車内１０２へ排出される。図２７に示すように、下流側排気風路２２２を流れる排気流５７に含まれる有機物量は、変化しない。 Then, the organic matter contained in the outside air is adsorbed by the adsorbent 58 arranged on the heat exchange element 115. As a result, as shown in FIG. 26, the amount of organic matter contained in the airflow 56 flowing through the downstream air supply air passage 212 is reduced as compared with the amount of organic matter contained in the outside air. Then, the organic matter adsorbed on the adsorbent 58 is gradually desorbed from the adsorbent 58 after time T12 and discharged into the vehicle 102. As shown in FIG. 27, the amount of organic matter contained in the exhaust flow 57 flowing through the downstream exhaust air passage 222 does not change.

A conceptual diagram for explaining the odor removal by the heat exchange element 115 is shown. FIG. 28 is a characteristic diagram showing the relationship between the amount of organic matter contained in the outside air and time in the odor component amount information according to the second embodiment of the present invention. FIG. 29 is a characteristic diagram showing the relationship between the amount of organic matter contained in the outside air, which is the airflow 56 in the upstream air-conditioned air passage 211 of the vehicle air-conditioned ventilation device 20 according to the second embodiment of the present invention, and time. .. FIG. 30 is a characteristic diagram showing the relationship between the amount of organic matter contained in the airflow 56 in the downstream air-conditioning air passage 212 of the vehicle air-conditioned ventilation device 20 according to the second embodiment of the present invention and the time. FIG. 31 is a characteristic diagram showing the relationship between the amount of organic matter contained in the exhaust flow 57 in the downstream exhaust air passage 222 of the vehicle air-conditioned ventilation device 20 according to the second embodiment of the present invention and time.
　車両１００が、車両用ナビゲーション装置４００で指定される走行ルートに従って走行し、時刻Ｔ１１から時刻Ｔ１２でトンネルを通過する。トンネル内は空気に含まれる臭気成分量が多くなり、図２８に示すように臭気成分量情報における外気に含まれる有機物量が多くなる。このとき、外気に含まれる有機物量が増加するので、図２９に示すように給気流５６に含まれる有機物量も増加する。そして、熱交換素子１１５で外気に含まれる有機物が、熱交換素子１１５に配置された吸着剤５８に吸着される。これにより、図３０に示すように、時刻Ｔ１１から時刻Ｔ１２において下流側給気風路２１２を流れる給気流５６に含まれる有機物量は、外気に含まれる有機物量に比べて減少する。 The vehicle 100 travels according to the travel route specified by the vehicle navigation device 400, and passes through the tunnel from time T11 to time T12. The amount of odorous components contained in the air increases in the tunnel, and as shown in FIG. 28, the amount of organic substances contained in the outside air in the odorous component amount information increases. At this time, since the amount of organic matter contained in the outside air increases, the amount of organic matter contained in the airflow 56 also increases as shown in FIG. 29. Then, the organic matter contained in the outside air in the heat exchange element 115 is adsorbed by the adsorbent 58 arranged in the heat exchange element 115. As a result, as shown in FIG. 30, the amount of organic matter contained in the airflow 56 flowing through the downstream air supply air passage 212 from time T11 to time T12 is smaller than the amount of organic matter contained in the outside air.
　ここで、トンネルを通過した時刻Ｔ１２において、熱交換部１１３の風路を第１の風路から第２の風路に切り換える。そして、給気流５６は、有機物量が吸着された吸着剤５８が配置されていない第２の層状気体流路５５を通過する。これにより、図３０に示すように、時刻Ｔ１２以降においては下流側給気風路２１２における給気流５６に含まれる有機物量は、図２６の場合と比べて減少する。 Here, at the time T12 when the tunnel is passed, the air passage of the heat exchange unit 113 is switched from the first air passage to the second air passage. Then, the air flow 56 passes through the second layered gas flow path 55 in which the adsorbent 58 on which the amount of organic matter is adsorbed is not arranged. As a result, as shown in FIG. 30, after time T12, the amount of organic matter contained in the air flow 56 in the downstream air supply air passage 212 is reduced as compared with the case of FIG. 26.
　そして、吸着剤５８に吸着された有機物は、通過する排気流５７に含まれる臭気成分と吸着剤５８に吸着濃縮されている臭気成分との濃度差が駆動力となり、一部が時刻Ｔ１２以降に吸着剤５８から脱着され、排気流５７の風圧によって脱着されて、排気流５７とともに車外に排出される。したがって、図３１に示すように、下流側排気風路２２２を流れる排気流５７に含まれる有機物量は、時刻Ｔ１２以降において増加する。 The organic matter adsorbed on the adsorbent 58 is driven by the difference in concentration between the odorous component contained in the passing exhaust flow 57 and the odorous component adsorbed and concentrated on the adsorbent 58, and a part of the organic matter is after time T12. It is desorbed from the adsorbent 58, desorbed by the wind pressure of the exhaust flow 57, and discharged to the outside of the vehicle together with the exhaust flow 57. Therefore, as shown in FIG. 31, the amount of organic matter contained in the exhaust flow 57 flowing through the downstream exhaust air passage 222 increases after the time T12.
　上記のように、臭気成分量情報に基づいて熱交換部１１３の風路を第１の風路と第２の風路との間で切り換えることにより、熱交換素子１１５の吸着剤５８に吸着された臭気成分が給気流５６に排出するのを抑制することができる。 As described above, by switching the air passage of the heat exchange unit 113 between the first air passage and the second air passage based on the odor component amount information, the heat exchange element 115 is adsorbed by the adsorbent 58. It is possible to suppress the discharge of the odorous component into the supply airflow 56.
　なお、制御部２０１は、上述した技術を組み合わせて、車外のガスセンサ１５と車内１０２のガスセンサ１５との検知結果の差分と、走行距離メーター１０４における走行距離と、の両方の情報に基づいて風路切換弁１１４を切り換える制御を行ってもよい。また、制御部２０１は、上述した技術を組み合わせて、車外のガスセンサ１５と車内１０２のガスセンサ１５との検知結果の差分と、走行距離メーター１０４における走行距離と、車両用ナビゲーション装置４００に記憶されている地理的位置情報と臭気成分量情報とが関連付けられた臭気情報と、に基づいて風路切換弁１１４を切り換える制御を行ってもよい。 In addition, the control unit 201 combines the above-mentioned technologies and is based on both information of the difference between the detection results of the gas sensor 15 outside the vehicle and the gas sensor 15 inside the vehicle 102 and the mileage of the mileage meter 104. Control to switch the switching valve 114 may be performed. Further, the control unit 201 combines the above-mentioned technologies and stores the difference between the detection results of the gas sensor 15 outside the vehicle and the gas sensor 15 inside the vehicle 102, the mileage in the mileage meter 104, and the mileage in the vehicle navigation device 400. Control may be performed to switch the air passage switching valve 114 based on the odor information associated with the geographical position information and the odor component amount information.
