Description

本発明は、車両に搭載される車両用空調装置に関する。   The present invention relates to a vehicle air conditioner mounted on a vehicle.

車両において、車室内の換気、暖房および冷房を行う場合に、顕熱交換器または全熱交換器などの熱交換器が使用されることがある。これらの熱交換器は、車室内から送出される内気と、車室内へ取り込む外気との間で、熱交換が行われるように設置される。   When a vehicle is ventilated, heated and cooled in a vehicle, a heat exchanger such as a sensible heat exchanger or a total heat exchanger may be used. These heat exchangers are installed so that heat exchange is performed between the inside air sent out from the passenger compartment and the outside air taken into the passenger compartment.

このような熱交換器によれば、外気温が低いときに、排出される内気と吸入される外気との間の熱交換により排出内気の熱回収が行われて、少ないエネルギーで車室内の温度を保つことができる。また、冷房時など、車室内の温度より外気温が高いときには、排出内気の冷熱回収(冷たい熱の回収)が行われて、冷房運転の省エネルギー化を図ることができる。   According to such a heat exchanger, when the outside air temperature is low, heat recovery of the discharged inside air is performed by heat exchange between the discharged inside air and the sucked outside air, and the temperature inside the vehicle interior is reduced with less energy. Can keep. In addition, when the outside air temperature is higher than the temperature in the passenger compartment, such as during cooling, cold air recovery (recovery of cold heat) is performed on the discharged inside air, and energy saving in the cooling operation can be achieved.

一般に、熱交換器による熱交換の効率には限界があり、熱交換後の排出内気には、比較的に多くの熱が残留している。従って、熱交換後の排出内気をそのまま車外に捨ててしまったのでは、冷暖房エネルギーの損出につながる。   Generally, the efficiency of heat exchange by a heat exchanger is limited, and a relatively large amount of heat remains in the exhausted air after heat exchange. Therefore, if the exhausted air after heat exchange is thrown out of the vehicle as it is, it leads to loss of air conditioning energy.

特許文献1には、車両用器空気調和装置の熱利用効率を上げるために、熱交換後の内気を外気導入口に戻す構成が開示されている。   Patent Document 1 discloses a configuration in which the inside air after heat exchange is returned to the outside air inlet in order to increase the heat utilization efficiency of the vehicular air conditioner.

特開2002−200910号公報JP 2002-200910 A

特許文献1の構成では、熱交換後の内気を外気導入口に戻して外気と混合させて車室内に導入するため、熱の利用効率は高くなる。しかしながら、この構成では、排出内気に含まれる二酸化炭素または汚れが車室内へ戻されるため、車室内の空気の質が低下するという課題がある。   In the configuration of Patent Document 1, since the inside air after heat exchange is returned to the outside air inlet and mixed with the outside air and introduced into the vehicle interior, the heat utilization efficiency is increased. However, in this configuration, since carbon dioxide or dirt contained in the exhausted air is returned to the vehicle interior, there is a problem that the quality of the air in the vehicle interior decreases.

本発明の目的は、車室内の空気の質を低下させることなく、熱利用効率を向上させて暖房運転または冷房運転の省エネルギー化を図ることのできる車両用空調装置を提供することである。   An object of the present invention is to provide a vehicle air conditioner capable of improving the heat utilization efficiency and reducing the energy consumption of the heating operation or the cooling operation without deteriorating the air quality in the passenger compartment.

本発明の一態様に係る車両用空調装置は、第1熱交換流路と第2熱交換流路とを有し前記第1熱交換流路に流れる空気と前記第2熱交換流路に流れる空気との間で熱を交換する第1熱交換器と、蒸発器および凝縮器を有するヒートポンプ回路と、前記蒸発器へ空気を流す冷却流路と、外気を順に前記第1熱交換流路および前記凝縮器に通過させて車室内へ送出可能な加温流路と、車室内から送出される内気を前記第2熱交換流路を通過させて前記冷却流路の前記蒸発器の上流へ送出可能な第1内気排出流路と、を具備する構成を採る。   The vehicle air conditioner according to an aspect of the present invention includes a first heat exchange channel and a second heat exchange channel, and flows through the first heat exchange channel and the second heat exchange channel. A first heat exchanger for exchanging heat with air; a heat pump circuit having an evaporator and a condenser; a cooling flow path for flowing air to the evaporator; A heating passage that can be passed through the condenser and sent into the passenger compartment, and an inside air that is sent out from the passenger compartment passes through the second heat exchange passage and is sent upstream of the evaporator in the cooling passage. A possible first inside air discharge flow path is employed.

本発明によれば、熱交換後の内気をヒートポンプ回路の蒸発器を通過させて、さらに、熱の回収を行うことができる。よって、熱利用効率が向上して空調運転の省エネルギー化が図れる。   According to the present invention, it is possible to further recover heat by allowing the inside air after heat exchange to pass through the evaporator of the heat pump circuit. Therefore, heat utilization efficiency is improved and energy saving of the air conditioning operation can be achieved.

図1は、本発明の実施の形態1の車両用空調装置の構成を示す模式図である。図1では暗い矢印により冷たい空気を、明るい矢印により温かい空気を表わしている。
(Embodiment 1)
FIG. 1 is a schematic diagram showing a configuration of a vehicle air conditioner according to Embodiment 1 of the present invention. In FIG. 1, a dark arrow represents cold air, and a bright arrow represents warm air.

この実施の形態1の車両用空調装置は、図1に示すように、第1熱交換器としての顕熱交換器11と、ヒートポンプ回路の凝縮器12および蒸発器13と、加温流路21と、冷却流路22と、内気排出流路(第1内気排出流路に相当)23と、ファン31,32とを備えている。   As shown in FIG. 1, the vehicle air conditioner of Embodiment 1 includes a sensible heat exchanger 11 as a first heat exchanger, a condenser 12 and an evaporator 13 of a heat pump circuit, and a heating channel 21. A cooling passage 22, an inside air discharge passage (corresponding to a first inside air discharge passage) 23, and fans 31 and 32.

図2は、顕熱交換器の一例を示す斜視図である。   FIG. 2 is a perspective view showing an example of a sensible heat exchanger.

顕熱交換器11は、図2に示すように、流路が固定された静止型の熱交換器である。顕熱交換器11は、隣接する2系統の流路A,Bを有し、一方の流路A(第1熱交換流路に相当)に低い温度の空気を流し、他方の流路B(第2熱交換流路に相当)に高い温度の空気を流す。それにより、顕熱交換器11では、流路Aと流路Bとの空気を混合せずに流路Bの空気の熱を流路Aの空気へ移動させることができる。各系統の流路A,Bには多数の細かい流路が設けられ、各系統の細かい流路を互いに交差させて配置することで、2系統の流路A,Bの接触面積が大きくされている。それにより、2系統の流路A,B間の熱交換量が大きくなっている。   As shown in FIG. 2, the sensible heat exchanger 11 is a stationary heat exchanger with a fixed flow path. The sensible heat exchanger 11 has two adjacent channels A and B, and flows low-temperature air through one channel A (corresponding to the first heat exchange channel) and the other channel B ( High temperature air is passed through the second heat exchange channel. Thereby, in the sensible heat exchanger 11, the heat of the air of the flow path B can be moved to the air of the flow path A without mixing the air of the flow path A and the flow path B. A large number of fine channels are provided in the channels A and B of each system, and the contact areas of the channels A and B of the two systems are increased by arranging the fine channels of each system so as to intersect each other. Yes. Thereby, the amount of heat exchange between the two channels A and B is increased.

蒸発器13は、ヒートポンプ回路の冷やされた冷媒を内部に流す一方、空気を大きな面積で接触しながら通過させて、冷媒と空気との間で熱の交換を行う。   The evaporator 13 allows the cooled refrigerant of the heat pump circuit to flow inside, and allows air to pass through in a large area while exchanging heat between the refrigerant and the air.

凝縮器12は、ヒートポンプ回路の熱せられた冷媒を内部に流す一方、空気を大きな面積で接触しながら通過させて、冷媒と空気との間で熱の交換を行う。   The condenser 12 allows the heated refrigerant of the heat pump circuit to flow inside, and allows air to pass through in a large area while exchanging heat between the refrigerant and the air.

加温流路21は、導入口が車外の空気の流入箇所に面し、送出口が車室内へ通じている。加温流路21の内部には、導入口から送出口へ向けて順番に、顕熱交換器11と凝縮器12とが配置されている。また、加温流路21には静圧を発生させて空気を流すファン32が設けられている。加温流路21に導入される外気は、顕熱交換器11の流路Bと凝縮器12とを流れて車室内へ送られる。   The heating channel 21 has an introduction port facing an inflow portion of air outside the vehicle, and a delivery port leading to the vehicle interior. Inside the heating channel 21, a sensible heat exchanger 11 and a condenser 12 are arranged in order from the inlet to the outlet. The heating channel 21 is provided with a fan 32 that generates static pressure and flows air. The outside air introduced into the heating channel 21 flows through the channel B of the sensible heat exchanger 11 and the condenser 12 and is sent to the vehicle interior.

冷却流路22は、導入口が車外の空気の流入箇所に面し、送出口が車外へ空気を排出できる箇所に面している。冷却流路22には、途中に蒸発器13と、空気を流すファン31とが設けられている。冷却流路22に導入される外気は、蒸発器13を通過して車外へ排出される。   The cooling channel 22 has an introduction port facing an inflow location of air outside the vehicle, and an output port facing a location where air can be discharged outside the vehicle. The cooling flow path 22 is provided with an evaporator 13 and a fan 31 through which air flows. The outside air introduced into the cooling flow path 22 passes through the evaporator 13 and is discharged outside the vehicle.

内気排出流路23は、導入口が車室内に通じ、途中で顕熱交換器11の流路Aが連結されて、送出口が冷却流路22における蒸発器13より上流側に通じている。また、内気排出流路23は、その送出口が冷却流路22のファン31より上流側に接続され、ファン31の静圧によって車室内から内気が吸引されるように構成されている。なお、内気排出流路23にファンを設けて空気を流すように構成してもよい。   The inside air discharge flow path 23 has an introduction port communicating with the vehicle interior, and the flow path A of the sensible heat exchanger 11 is connected on the way, and a delivery port communicates upstream of the evaporator 13 in the cooling flow path 22. Further, the inside air discharge passage 23 is configured such that the outlet is connected to the upstream side of the fan 31 of the cooling passage 22 and the inside air is sucked from the vehicle interior by the static pressure of the fan 31. Note that a fan may be provided in the inside air discharge flow path 23 so that air flows.

[Specific configuration example]
FIG. 3 is a diagram showing a specific configuration of the vehicle air conditioner of the first embodiment. In FIG. 3, the configuration above the fans 31 and 32 is indicated by two-dot oblique lines. FIG. 4 is a configuration diagram showing the first fan of the first embodiment and its periphery, and FIG. 5 is a configuration diagram showing the second fan of the first embodiment and its periphery.

図3は、車両に搭載された車両用空調装置を上方から見た配置構成を示している。実施の形態1の車両用空調装置においては、凝縮器12および蒸発器13が車両の内壁W0に沿って水平方向に並んで配置されている。また、この車両用空調装置においては、2つのファン(例えばブロアファン)31,32は、凝縮器12および蒸発器13より内壁W0の反対側にずれた位置にそれぞれ設置されている。   FIG. 3 shows an arrangement configuration of the vehicle air conditioner mounted on the vehicle as viewed from above. In the vehicle air conditioner of the first embodiment, the condenser 12 and the evaporator 13 are arranged in the horizontal direction along the inner wall W0 of the vehicle. Further, in this vehicle air conditioner, the two fans (for example, blower fans) 31 and 32 are respectively installed at positions shifted from the condenser 12 and the evaporator 13 to the opposite side of the inner wall W0.

図4に示すように、顕熱交換器11はファン32の上部(吸気口側)に配置されている。顕熱交換器11は、流路Bが上下方向(図3の紙面に垂直な方向、図4の上下方向)に進み、流路Aが水平方向(図3および図4の左右方向)に進むように配置されている。   As shown in FIG. 4, the sensible heat exchanger 11 is disposed on the upper portion (intake port side) of the fan 32. In the sensible heat exchanger 11, the flow path B proceeds in the vertical direction (the direction perpendicular to the paper surface of FIG. 3, the vertical direction in FIG. 4), and the flow path A travels in the horizontal direction (the horizontal direction in FIGS. 3 and 4). Are arranged as follows.

図3に具体的に示した車両用空調装置は、図1に示した構成に加えて、吸気弁21A,22A、排出弁22B、内気戻し流路23b、および、車室内ダクト101を備えている。   The vehicle air conditioner specifically shown in FIG. 3 includes intake valves 21A and 22A, a discharge valve 22B, an inside air return passage 23b, and a vehicle interior duct 101 in addition to the configuration shown in FIG. .

吸気弁21Aは、加温流路21の導入口を開閉する弁であり、吸気弁21Aが開くことで加温流路21に外気が導入される。また、吸気弁21Aの開度を変更することで、内気戻し流路23bを介して加温流路21に導入される内気の割合を調整することができる。この吸気弁21Aは、電気的な制御、或いは、車両搭乗者の操作によって開度を変更できるように構成されている。加温流路21における内気の導入箇所は、凝縮器12の上流側に設定されている。   The intake valve 21 </ b> A is a valve that opens and closes the inlet of the heating channel 21, and outside air is introduced into the heating channel 21 by opening the intake valve 21 </ b> A. Further, by changing the opening degree of the intake valve 21A, the ratio of the inside air introduced into the warming passage 21 via the inside air return passage 23b can be adjusted. The intake valve 21A is configured to be able to change the opening degree by electrical control or operation of a vehicle occupant. The place where the inside air is introduced in the heating channel 21 is set on the upstream side of the condenser 12.

吸気弁22Aは、冷却流路22の導入口を開閉する弁であり、吸気弁22Aが開くことで冷却流路22に外気が導入される。また、吸気弁22Aの開度を変更することで、内気排出流路23を介して顕熱交換器11を経て送られてくる内気の割合を調整することができる。吸気弁22Aは、電気的な制御、或いは、車両搭乗者の操作によって開度を変更できるように構成されている。   The intake valve 22A is a valve that opens and closes the inlet of the cooling flow path 22, and outside air is introduced into the cooling flow path 22 when the intake valve 22A is opened. Moreover, the ratio of the inside air sent through the sensible heat exchanger 11 via the inside air discharge passage 23 can be adjusted by changing the opening degree of the intake valve 22A. The intake valve 22A is configured to be able to change the opening degree by electrical control or operation of a vehicle occupant.

排出弁22Bは、暖房時に開放されて蒸発器13を通過した冷たい空気を車外へ排出する弁である。   The discharge valve 22B is a valve that discharges cold air that has been opened during heating and passed through the evaporator 13 to the outside of the vehicle.

車室内ダクト101は、車両用空調装置から送出される空気を車室内の所定の送風口まで導くダクトである。   The vehicle interior duct 101 is a duct that guides air sent from the vehicle air conditioner to a predetermined air outlet in the vehicle interior.

[暖房運転動作]
実施の形態1の車両用空調装置では、図3および図4に示すように、暖房運転時に、吸気弁21Aが所定の開度で開いて、加温流路21に外気と内気とが導入される。この外気は、ファン32の静圧により吸気弁21Aの開口から導入され、内気は、ファン32の静圧により内気排出流路23および内気戻し流路23bを介して導入される。加温流路21に導入される外気と内気との割合は、例えば、外気が80パーセント、内気が20パーセントの割合に制御される。
[Heating operation]
In the vehicle air conditioner of the first embodiment, as shown in FIGS. 3 and 4, during the heating operation, the intake valve 21 </ b> A opens at a predetermined opening, and outside air and inside air are introduced into the heating channel 21. The The outside air is introduced from the opening of the intake valve 21A by the static pressure of the fan 32, and the inside air is introduced by the static pressure of the fan 32 via the inside air discharge passage 23 and the inside air return passage 23b. The ratio between the outside air and the inside air introduced into the heating channel 21 is controlled to a ratio of 80% for outside air and 20% for inside air, for example.

なお、内気の戻りが多くなると、車室内の空気の二酸化炭素濃度および湿度が上昇し、汚れも多くなる。よって、加温流路21に導入される内気の割合は、上限30%の範囲で制御される。   Note that when the return of the inside air increases, the carbon dioxide concentration and humidity of the air in the passenger compartment increase and the amount of dirt increases. Therefore, the ratio of the inside air introduced into the heating channel 21 is controlled within the upper limit of 30%.

また、暖房運転時には、図3および図5に示すように、吸気弁22Aが所定の開度で開いて、冷却流路22に外気と内気とが導入される。この外気は、ファン31の静圧により吸気弁22Aの開口から導入され、内気は、ファン31の静圧により内気排出流路23および顕熱交換器11を介して導入される。冷却流路22に導入される外気と内気との割合は、例えば、外気が70パーセント、内気が30%の割合に制御される。   Further, during the heating operation, as shown in FIGS. 3 and 5, the intake valve 22 </ b> A opens at a predetermined opening, and the outside air and the inside air are introduced into the cooling flow path 22. The outside air is introduced from the opening of the intake valve 22 </ b> A due to the static pressure of the fan 31, and the inside air is introduced via the inside air discharge passage 23 and the sensible heat exchanger 11 due to the static pressure of the fan 31. The ratio between the outside air and the inside air introduced into the cooling flow path 22 is controlled, for example, to a ratio of 70% outside air and 30% inside air.

加温流路21に導入された空気は、顕熱交換器11の流路Aを通過して、流路Bの温度の高い内気と熱交換して温められる。さらに、この空気は、凝縮器12を通過して温められて車室内へ供給される。   The air introduced into the heating channel 21 passes through the channel A of the sensible heat exchanger 11 and is warmed by exchanging heat with the internal air having a high temperature in the channel B. Further, the air passes through the condenser 12 and is warmed and supplied to the passenger compartment.

一方、冷却流路22に導入された空気は、蒸発器13を通過して冷媒を温めて車室外へ排出される。ここで、冷却流路22に導入される内気は、顕熱交換器11の流路Bを通過して熱交換により冷やされるものの、熱の残留により外気より温度が高くなる。しかし、その後、この内気は蒸発器13を通過して低温の冷媒を温めてから車外へ排出されることになる。   On the other hand, the air introduced into the cooling flow path 22 passes through the evaporator 13 to warm the refrigerant and is discharged out of the passenger compartment. Here, although the inside air introduced into the cooling flow path 22 passes through the flow path B of the sensible heat exchanger 11 and is cooled by heat exchange, the temperature becomes higher than the outside air due to heat remaining. However, after that, the inside air passes through the evaporator 13 and warms the low-temperature refrigerant, and then is discharged outside the vehicle.

つまり、暖房および換気に伴って車室内から車外に排出される内気は、顕熱交換器11で吸入外気に熱を移動させる熱回収と、蒸発器13で低温の冷媒に熱を移動させる熱回収と、二段階の熱回収を経てから車外に排出される。   That is, the internal air discharged from the vehicle interior to the outside of the vehicle with heating and ventilation is heat recovery for transferring heat to the intake external air by the sensible heat exchanger 11 and heat recovery for transferring heat to the low-temperature refrigerant by the evaporator 13. After two stages of heat recovery, it is discharged outside the vehicle.

従って、実施の形態1の車両用空調装置によれば、暖房運転時の熱の利用効率が向上する。よって、実施の形態1の車両用空調装置によれば、車室内の空気の質を低下させずに、暖房運転の省エネルギー化をより図ることができる。このような暖房運転の省エネルギー化は、車両として熱の発生量の少ない電気自動車あるいはハイブリッド自動車において、特に有用なものとなる。   Therefore, according to the vehicle air conditioner of Embodiment 1, the heat utilization efficiency during the heating operation is improved. Therefore, according to the vehicle air conditioner of the first embodiment, it is possible to further save energy in the heating operation without lowering the air quality in the passenger compartment. Such energy saving in the heating operation is particularly useful in an electric vehicle or a hybrid vehicle that generates a small amount of heat as a vehicle.

The structure of the sensible heat exchanger 14 is the same as that of the sensible heat exchanger 11.

[暖房運転動作]
図10には、実施の形態2の車両用空調装置の暖房運転時の動作例を示す模式図である。
[Heating operation]
FIG. 10 is a schematic diagram illustrating an operation example during heating operation of the vehicle air conditioner according to the second embodiment.

実施の形態2の車両用空調装置では、暖房運転時に、実施の形態1と同様の空気の流れによって、車室内の暖房および換気が行われる。   In the vehicle air conditioner of the second embodiment, the vehicle interior is heated and ventilated by the same air flow as in the first embodiment during the heating operation.

すなわち、図10に示すように、暖房運転時には、流量変更弁24Aが閉じられて内気排出流路24および顕熱交換器14の一方の流路に内気が流されない。顕熱交換器14の一方の流路に空気が流れないことで、顕熱交換器14における熱交換は行われない。   That is, as shown in FIG. 10, during the heating operation, the flow rate change valve 24 </ b> A is closed, and the inside air is not passed through one of the inside air discharge passage 24 and the sensible heat exchanger 14. Since air does not flow through one flow path of the sensible heat exchanger 14, heat exchange in the sensible heat exchanger 14 is not performed.

もう一方の流量変更弁23Aは開かれて、内気排出流路23および顕熱交換器11の一方の流路は内気が流される。   The other flow rate change valve 23 </ b> A is opened, and the inside air flows through the inside air discharge passage 23 and one of the sensible heat exchanger 11.

また、送出先変更弁21C,22Cは、冷却流路22からの空気が車外に排出され、加温流路21からの空気が車室内に送られるように切り替えられる。   The delivery destination changing valves 21C and 22C are switched so that the air from the cooling flow path 22 is discharged outside the vehicle and the air from the heating flow path 21 is sent into the vehicle interior.

そして、ファン31,32が駆動されて、加温流路21と冷却流路22とに空気が流される。   Then, the fans 31 and 32 are driven, and air flows through the heating channel 21 and the cooling channel 22.

このような暖房運転により、実施の形態1と同様に、車室内の換気とヒートポンプ回路による暖房とが行われる。また、暖房および換気に伴って車室内から車外に排出される内気は、顕熱交換器11で吸入外気に熱を移動させる熱回収と、蒸発器13で低温の冷媒に熱を移動させる熱回収と、二段階の熱回収を経てから車外に排出される。よって、暖房運転時の熱の利用効率が向上して、車室内の空気の質を低下させずに、暖房の省エネルギー化を図ることができる。   By such a heating operation, as in the first embodiment, the vehicle interior is ventilated and heated by a heat pump circuit. Moreover, the inside air exhausted from the vehicle interior to the outside of the vehicle with heating and ventilation is heat recovery for transferring heat to the intake outside air by the sensible heat exchanger 11 and heat recovery for transferring heat to the low-temperature refrigerant by the evaporator 13. After two stages of heat recovery, it is discharged outside the vehicle. Therefore, the heat use efficiency during the heating operation is improved, and the energy saving of the heating can be achieved without deteriorating the air quality in the passenger compartment.

[冷房運転動作]
図11には、実施の形態2の車両用空調装置の冷房運転時の動作例を示す模式図である。
[Cooling operation]
FIG. 11 is a schematic diagram illustrating an operation example during the cooling operation of the vehicle air conditioner according to the second embodiment.

実施の形態2の車両用空調装置では、冷房運転時に、次のような空気の流れによって、車室内の冷房および換気が行われる。   In the vehicle air conditioner of the second embodiment, the cooling and ventilation of the passenger compartment is performed by the following air flow during the cooling operation.

すなわち、図11に示すように、冷房運転時には、流量変更弁23Aが閉じられて内気排出流路23および顕熱交換器11の一方の流路に内気が流されない。顕熱交換器11の一方の流路に空気が流れないことで、顕熱交換器11における熱交換は行われない。   That is, as shown in FIG. 11, during the cooling operation, the flow rate change valve 23 </ b> A is closed, and the inside air is not flown into one of the inside air discharge passage 23 and the sensible heat exchanger 11. Since air does not flow through one flow path of the sensible heat exchanger 11, heat exchange in the sensible heat exchanger 11 is not performed.

もう一方の流量変更弁24Aは開かれて、内気排出流路24および顕熱交換器14の一方の流路に内気が流される。   The other flow rate changing valve 24 </ b> A is opened, and the inside air is caused to flow through the inside air discharge passage 24 and one passage of the sensible heat exchanger 14.

また、送出先変更弁21C,22Cは、冷却流路22からの空気が車室内へ送られ、加温流路21からの空気が車外へ排出されるように切り替えられる。   The delivery destination changing valves 21C and 22C are switched so that air from the cooling flow path 22 is sent into the vehicle compartment and air from the heating flow path 21 is discharged outside the vehicle.

そして、ファン31,32が駆動されて、加温流路21と冷却流路22とに空気が流される。   Then, the fans 31 and 32 are driven, and air flows through the heating channel 21 and the cooling channel 22.

このような冷房運転により、温かい外気が、顕熱交換器14において内気と熱交換されて冷やされ、その後、蒸発器13で冷媒と熱交換されてより冷やされる。そして、この冷やされた外気が車室内へ送られて、車室内の換気と冷房とが行われる。   By such a cooling operation, the warm outside air is cooled by exchanging heat with the inside air in the sensible heat exchanger 14, and then is further cooled by exchanging heat with the refrigerant in the evaporator 13. Then, the cooled outside air is sent to the vehicle interior, and ventilation and cooling of the vehicle interior are performed.

また、上記の冷房および換気に伴って車室内から車外に排出される内気は、先ず、顕熱交換器14において吸入外気に冷熱を移動させる冷熱回収が行われる。さらに、その後、後、外気と混合されて凝縮器12を通過することで、高温の冷媒に冷熱を移動させる冷熱回収が行われる。そして、このような二段階の冷熱回収を経てから車外に排出される。   In addition, the internal air discharged from the vehicle interior to the outside of the vehicle in accordance with the cooling and ventilation described above is first subjected to cold energy recovery in which the sensible heat exchanger 14 moves the cold air to the intake external air. Furthermore, after that, cold energy recovery is performed in which the cold energy is transferred to a high-temperature refrigerant by being mixed with outside air and passing through the condenser 12. And after passing through such two-stage cold energy recovery, it is discharged outside the vehicle.

以上のように、実施の形態2の車両用空調装置によれば、暖房運転時および冷房運転時の両方において、排出される内気の熱回収(冷房時は冷熱回収)が多量に行われる。従って、暖房運転時、ならびに、冷房運転時において、熱の利用効率が向上する。よって、実施の形態2の車両用空調装置によれば、車室内の空気の質を低下させずに、空調運転の省エネルギー化をより図ることができる。   As described above, according to the vehicle air conditioner of the second embodiment, a large amount of heat recovery of the discharged inside air (cold heat recovery during cooling) is performed both during the heating operation and during the cooling operation. Therefore, heat utilization efficiency is improved during heating operation and cooling operation. Therefore, according to the vehicle air conditioner of the second embodiment, it is possible to further save energy in the air conditioning operation without deteriorating the air quality in the passenger compartment.

However, a configuration using various known valves can be adopted instead of these configurations. Moreover, the structure which changes the air flow or flow volume of each flow path by the action | operation and stop of a fan, and control of the rotation amount of a fan instead of a valve can also be employ | adopted.

また、上記実施の形態では、熱交換器として、顕熱交換器を適用した構成を例にとって説明したが、全熱交換器を適用した構成を採用することもできる。その他、吸入外気と排出内気との割合、吸入外気と内気の戻し量との割合など、実施の形態で示した細部は発明の趣旨を逸脱しない範囲で変更可能である。   Moreover, although the said embodiment demonstrated as an example the structure which applied the sensible heat exchanger as a heat exchanger, the structure which applied the total heat exchanger is also employable.
