　室内空気[interior air]が吸込口１０２から吸い込まれ、吸い込まれた空気はエバポレータ１０６及びヒータ１０７によって所望温度の空調風[conditioned air]とされる。空調風は、吹出口１０３から吹き出される。吹き出された空調風は、乗員の周囲を通って再び吸込口１０２から吸い込まれる。このような空調風の循環によって乗員の周囲に空調風の流れが形成され、ゾーン空調が実現される。ゾーン空調によって即冷性[quick cooling performance]及び即暖性[quick heating performance]が向上される。 Indoor air [interior air] is sucked from the suction port 102, and the sucked air is converted into conditioned air at a desired temperature by the evaporator 106 and the heater 107. The conditioned air is blown out from the air outlet 103. The conditioned air blown out is sucked again from the suction port 102 through the occupant. By such circulation of the conditioned air, a flow of conditioned air is formed around the occupant, and zone air conditioning is realized. Zone air conditioning improves quick cooling performance and quick heating performance.
　下記特許文献２は、他の従来のゾーン空調システムを開示している。特許文献２に開示されている車両用空気調和システム１１０は、図１２に示されるように、インストルメントパネル内に配置されたメイン空調装置[main air-conditioner]（図示せず）と、シート空調装置[in-seat air-conditioner]１１１とを備えている。シート空調装置１１１は、シート１１２のシートバック１１２ｂの上部に開口された第１吸込口１１３、シートバック１１２ｂの下部に開口された第１吹出口１１４、第１吸込口１１３と第１吹出口１１４とを連通させる第１送風路１１５、シートクッション１１２ａの下面に開口された第２吸込口１２０、シートクッション１１２ａの上面に開口された第２吹出口１２１、及び、第２吸込口１２０と第２吹出口１２１とを連通させる第２送風路１２２を備えている。第１送風路１１５には、送風機１１６及び熱交換器１１７が配置され、第２送風路１２２には、送風機１２３及び熱交換器１２４が配置されている。第２吸込口１２０の下方には、メイン空調装置から延設されたダクト１３０の先端が開口されている。 The following Patent Document 2 discloses another conventional zone air conditioning system. As shown in FIG. 12, a vehicle air conditioning system 110 disclosed in Patent Document 2 includes a main air conditioner [main air-conditioner] (not shown) disposed in an instrument panel, and a seat air conditioner. A device [in-seat air-conditioner] 111. The seat air conditioner 111 includes a first suction port 113 opened at the upper part of the seat back 112b of the seat 112, a first air outlet 114 opened at the lower part of the seat back 112b, the first air inlet 113 and the first air outlet 114. The first air passage 115 that communicates with the second air inlet 120, the second air inlet 120 that is opened on the lower surface of the seat cushion 112a, the second air outlet 121 that is opened on the upper surface of the seat cushion 112a, and the second air inlet 120 and second The 2nd ventilation path 122 which connects the blower outlet 121 is provided. A blower 116 and a heat exchanger 117 are disposed in the first air passage 115, and a blower 123 and a heat exchanger 124 are disposed in the second air passage 122. Below the second suction port 120, a tip of a duct 130 extending from the main air conditioner is opened.
　メイン空調装置からの所望温度の空調風は、車室前部から車室へと吹き出される。吹き出された空調風は、乗員の周辺を通って第１吸込口１１３から吸い込まれて、回収されるる。これにより、第１吸込口１１３より後方の車室空間への空調風の流れが抑制される。第１吸込口１１３から吸い込まれた空調風は、熱交換器１１７を通過して第１吹出口１１４から車室へと吹き出される。また、メイン空調装置からの所望温度の空調風は、ダクト１３０からシートクッション１１２ａの下面へと吹き出される。空調風は、第２吸込口１２０から吸い込まれ、熱交換器１２４を通過して第２吹出口１２１から車室へと吹き出される。第１吹出口１１４及び第２吹出口１２１から吹き出された空調風は、乗員の周辺を通って車室内前方に流れて、再びメイン空調装置へと戻される。このような空調風の循環によって、乗員の周囲に空調風の強い流れが形成され、ゾーン空調が実現される。ゾーン空調によって即冷性及び即暖性が向上される。 Conditioned air from the main air conditioner is blown out from the front of the passenger compartment to the passenger compartment. The conditioned air blown out is sucked from the first suction port 113 through the periphery of the occupant and collected. Thereby, the flow of the conditioned air to the passenger compartment space behind the first suction port 113 is suppressed. The conditioned air sucked from the first suction port 113 passes through the heat exchanger 117 and is blown out from the first air outlet 114 to the passenger compartment. Further, the conditioned air from the main air conditioner is blown out from the duct 130 to the lower surface of the seat cushion 112a.

The conditioned air blown from the first air outlet 114 and the second air outlet 121 flows to the front of the passenger compartment through the periphery of the occupant and is returned to the main air conditioner again. By such circulation of the conditioned air, a strong flow of the conditioned air is formed around the occupant, thereby realizing zone air conditioning. Immediate cooling and warming are improved by zone air conditioning.

　しかし、上述した図１１に示される空気調和システム１００では、ゾーン空調専用のエバポレータ１０６及びヒータ１０７を設ける必要があるので、システムの複雑化や高コスト化を招いてしまう。 However, in the air conditioning system 100 shown in FIG. 11 described above, since it is necessary to provide the evaporator 106 and the heater 107 dedicated to zone air conditioning, the system becomes complicated and expensive.
　また、上述した図１２に示される空気調和システム１１０では、メイン空調装置（図示せず）の熱交換器を利用して空調風が生成される。また、第１吹出口１１４や第２吹出口１２１から吹き出された空調風は、メイン空調装置の内気導入口の吸込力のみによって車室内部を流れてメイン空調装置に戻される。車室内部を流れる間に熱を大きく損失した空調風がメイン空調装置に戻されるので、ゾーン空調であるのにもかかわらずメイン空調装置への負荷が大きい。また、シート１１２の第１吹出口１１４や第２吹出口１２１から吹き出された空調風は、メイン空調装置の内気導入口よりも近い位置に開口されているシート１１２の第１吸込口１１３や第２吸込口１２０から吸い込まれ易く、第１吹出口１１４や第２吹出口１２１から吹き出された空調風がメイン空調装置に戻らない。従って、シート空調装置１１１の熱交換器１１７，１２４がないと、所望温度でない室内空気の循環流が形成されてしまう。すなわち、所望温度でない室内空気の循環流を防止して快適なゾーン空調を実現するためにはシート空調装置１１１の熱交換器１１７，１２４が必要となり、システムの複雑化や高コスト化を招いてしまう。 In the air conditioning system 110 shown in FIG. 12 described above, conditioned air is generated using a heat exchanger of a main air conditioner (not shown). In addition, the conditioned air blown from the first air outlet 114 and the second air outlet 121 flows through the vehicle interior only by the suction force of the inside air introduction port of the main air conditioner and is returned to the main air conditioner. Since the conditioned air that has lost a large amount of heat while flowing through the passenger compartment is returned to the main air conditioner, the load on the main air conditioner is large despite the zone air conditioning. In addition, the conditioned air blown from the first air outlet 114 and the second air outlet 121 of the seat 112 is opened at a position closer to the inside air inlet of the main air conditioner and the first air inlet 113 and the second air outlet of the seat 112. The air-conditioning air blown out from the first air outlet 114 and the second air outlet 121 does not return to the main air conditioner because it is easily sucked from the second air inlet 120. Therefore, without the heat exchangers 117 and 124 of the seat air conditioner 111, a circulating flow of indoor air that is not at a desired temperature is formed. In other words, heat exchangers 117 and 124 of the seat air conditioner 111 are required to prevent the circulation of indoor air that is not at a desired temperature and to realize comfortable zone air conditioning, resulting in a complicated system and high cost. End up.
　また、図１１や図１２に示される空気調和システム１００又は１１０が、乗員一人毎にゾーン空調を行うように構成されると、非常に複雑化すると共に、コストが増加する。一方、空気調和システム１００又は１１０が、複数の乗員（例えば運転席と助手席の乗員）に対してゾーン空調を行うように構成されると、乗員一人毎にゾーン空調を行うことができず、エネルギーやコストの観点からは過剰なゾーン空調システムとなる。また、乗用車の平均乗車率が１．４人である（日本の場合）ことや、乗員の様々な空調に対する要望に対応することを考慮すると、ゾーン空調領域を簡単に可変できるシステムが望まれている。 Further, if the air conditioning system 100 or 110 shown in FIG. 11 or FIG. 12 is configured to perform zone air conditioning for each occupant, the air conditioning system 100 or 110 becomes very complicated and the cost increases. On the other hand, if the air conditioning system 100 or 110 is configured to perform zone air conditioning for a plurality of passengers (for example, a driver seat and a passenger seat passenger), zone air conditioning cannot be performed for each passenger, From the viewpoint of energy and cost, it becomes an excessive zone air conditioning system. In addition, considering that the average occupancy rate of passenger cars is 1.4 (in Japan) and responding to passengers' various requests for air conditioning, a system that can easily change the zone air-conditioning area is desired. Yes.
　本発明の目的は、システムの単純化及び低コスト化を実現できると共に、空調負荷の低減による省エネルギー化の可能な快適なゾーン空調を行うことができ、かつ、ゾーン空調領域を簡単に可変できる車両用空気調和システムを提供することにある。 An object of the present invention is to realize a vehicle that can realize a simplified system and a low cost, can perform comfortable zone air conditioning that can save energy by reducing an air conditioning load, and can easily change the zone air conditioning region. It is to provide an air conditioning system for use.
　本発明の特徴は、車両用空気調和システムであって、メイン送風機、メインダクト及び熱交換部を有し、前記送風機によって前記メインダクト内に吸い込んだ空気を前記熱交換部によって所望の空調風に変換して車室内に吹き出すよう構成された空気調和装置と、乗員のシート周辺に配置された複数の吸込口と、一側の端部が前記複数の吸込口に接続され、前記複数の吸込口から前記空調風を吸い込んで前記空気調和装置に戻すことの可能なサブダクトと、前記複数の吸込口の中から、前記空調風の吸い込みに使用される少なくとも一つの吸込口を選択する吸込口選択器と、を備えている車両用空気調和システムを提供する。 A feature of the present invention is an air conditioning system for a vehicle, which includes a main blower, a main duct, and a heat exchange unit, and converts the air sucked into the main duct by the blower into a desired conditioned air by the heat exchange unit. An air conditioner configured to be converted and blown into the passenger compartment, a plurality of suction ports arranged around the occupant's seat, and one end portion connected to the plurality of suction ports, the plurality of suction ports A sub duct capable of sucking the conditioned air and returning it to the air conditioner, and a suction port selector for selecting at least one suction port used for sucking the conditioned air from the plurality of suction ports And an air conditioning system for a vehicle comprising:
　上記特徴によれば、空気調和装置によって車室内に吹き出された空調風は、乗員のシート周辺に配置された吸込口から吸い込まれる。これにより、空調風が回収されると共に吸込口より後方に流れる空調風が抑制され、強く快適なゾーン空調を行うことができる。また、吸込口から吸い込まれた空調風は、サブダクトを通って空気調和装置に戻される。このような空調風の循環によって、乗員の周囲に空調風の快適な流れが形成され、好適なゾーン空調が形成される。 According to the above feature, the conditioned air blown into the passenger compartment by the air conditioner is sucked from the suction port arranged around the passenger's seat. As a result, the conditioned air is recovered and the conditioned air flowing backward from the suction port is suppressed, and strong and comfortable zone air conditioning can be performed. In addition, the conditioned air sucked from the suction port is returned to the air conditioner through the sub duct. By such circulation of the conditioned air, a comfortable flow of the conditioned air is formed around the occupant, and a suitable zone air conditioner is formed.
　また、ゾーン空調モードでは、空気調和装置の熱交換部によって所望温度の空調風が生成できるので、ゾーン空調専用の熱交換部の設置が必須ではなく、システムの単純化や低コスト化を実現できる。さらに、吸込口から吸い込まれた空調風は、車室内に一切吹き出されないので、上述した図１２に示される空気調和システム１１０のように所望温度でない循環流が乗員周辺に形成されることがない。 In the zone air-conditioning mode, air-conditioning air at a desired temperature can be generated by the heat exchange unit of the air conditioner. Therefore, installation of a heat exchange unit dedicated to zone air-conditioning is not essential, and simplification and cost reduction of the system can be realized. . Furthermore, since the conditioned air sucked from the suction port is not blown out into the passenger compartment, a circulating flow having an undesired temperature is not formed around the occupant unlike the air conditioning system 110 shown in FIG. 12 described above.
　また、吸込口選択器によって空調風の吸込口を選択できるため、ゾーン空調領域を可変制御できる。 Also, since the air inlet can be selected by the air inlet selector, the zone air conditioning area can be variably controlled.

Both of the suction ports around the side seat, (ii) only the suction port around the driver seat side seat, or (ii) only the suction port around the passenger seat side seat It is preferable to select the at least one suction port used for suction.
　さらに、前記空気調和装置が、前記運転手側シートの周辺に前記空調風を吹き出す吹出口と、前記助手席側シートの周辺に前記空調風を吹き出す吹出口と、前記吸込口の中から、前記空調風の吹き出しに使用される少なくとも一つの吹出口を選択する吹出口選択器とをさらに備えており、前記吹出口選択器が、前記吸込口選択器によって選択された前記少なくとも一つの吸込口に対応させて、前記空調風の吹き出しに使用される前記少なくとも一つの吹出口を協調選択する、ことが好ましい。 Further, the air conditioner includes an air outlet that blows the conditioned air around the driver side seat, an air outlet that blows the conditioned air around the passenger seat, and the suction port. An air outlet selector that selects at least one air outlet used for blowing out the conditioned air, and the air outlet selector is connected to the at least one air inlet selected by the air inlet selector. Correspondingly, it is preferable to cooperatively select the at least one outlet used for blowing the conditioned air.
　ここで、前記吹出口がベント吹出口である場合、前記吹出口がフット吹出口である場合、前記吹出口がベント吹出口及びフット吹出口である場合、がある。 Here, when the air outlet is a vent air outlet, when the air outlet is a foot air outlet, the air outlet may be a vent air outlet and a foot air outlet.
　また、前記サブダクトの他側の端部が、前記メイン送風機より上流で前記メインダクトと接続されている、ことが好ましい。 Further, it is preferable that the other end of the sub duct is connected to the main duct upstream from the main blower.
　あるいは、前記サブダクトの他側の端部が、前記送風機と前記熱交換部との間で前記メインダクトと接続されており、前記吸込口選択器によって選択された前記少なくとも一つの吸込口から前記サブダクト内に空気を流入させるサブ送風機を備えている、ことが好ましい。 Alternatively, the other end of the sub duct is connected to the main duct between the blower and the heat exchanging unit, and the sub duct is selected from the at least one suction port selected by the suction port selector. It is preferable that a sub-blower that allows air to flow in is provided.

　ベント吹出口選択ドア６０及びフット吹出口選択ドア６１は、制御部[controller]５０によって制御される。 The vent outlet selection door 60 and the foot outlet selection door 61 are controlled by a controller 50.
　図１及び図２に示されるように、右フロントシート４の吸込口３０Ａ（又は、左フロントシート４の吸込口３０Ｂ）は、シートバック４ｂの上部[upper portion]で、ヘッドレスト４ｃの両側に設けられている。合計四つの吸込口３０Ａ及び３０Ｂは、フロントシート４の乗員の上半身のすぐ後に開口している。 As shown in FIGS. 1 and 2, the suction port 30A of the right front seat 4 (or the suction port 30B of the left front seat 4) is provided on both sides of the headrest 4c at the upper part of the seat back 4b. It has been. A total of four inlets 30 </ b> A and 30 </ b> B are opened immediately after the upper body of the occupant of the front seat 4.
　図３に示されるように、サブダクト４０の一端は、吸込口３０Ａ及び３０Ｂに接続されている。サブダクト４０の他端は、送風機１７より上流でメインダクト１３に接続されている。サブダクト４０のメインダクト１３との接続位置には、選択ドア[selector door]４１が配されている。選択ドア４１は、サブダクト４０の内部とメインダクト１３の内部との連通を遮蔽可能である。選択ドア４１の動作は、制御部５０によって制御される。 As shown in FIG. 3, one end of the sub duct 40 is connected to the suction ports 30A and 30B. The other end of the sub duct 40 is connected to the main duct 13 upstream from the blower 17. A selection door 41 is arranged at a connection position of the sub duct 40 with the main duct 13. The selection door 41 can block communication between the inside of the sub duct 40 and the inside of the main duct 13. The operation of the selection door 41 is controlled by the control unit 50.
　また、吸込口選択器[suction port selector]として設けられた吸込口選択ドア６２が、サブダクト４０内の運転席側吸込口３０Ａと助手席側吸込口３０Ｂとの合流位置に配置されている。吸込口選択ドア６２は、運転席側吸込口３０Ａから空調風を吸い込む運転席側位置と、助手席側の吸込口３０Ｂから空調風を吸い込む助手席側位置と、運転席側吸込口３０Ａ及び助手席側吸込口３０Ｂの双方から空調風を吸い込む中間位置とに切り替え可能である。吸込口選択ドア６２は、制御部５０によって制御される。 Further, a suction port selection door 62 provided as a suction port selector [suction port selector] is arranged at a confluence position between the driver seat side suction port 30A and the passenger seat side suction port 30B in the sub duct 40. The suction port selection door 62 includes a driver seat side position for sucking conditioned air from the driver seat side suction port 30A, a passenger seat side position for sucking conditioned air from the passenger seat side suction port 30B, and the driver seat side suction port 30A and the assistant. It is possible to switch to an intermediate position for sucking conditioned air from both of the seat side suction ports 30B. The suction port selection door 62 is controlled by the control unit 50.
　また、サブダクト４０内には、温度センサＳ１が配されている。温度センサＳ１は、吸込口３０Ａ及び３０Ｂから吸い込まれた空調風の温度を検出する。温度センサＳ１の検出データは、制御部５０に出力される。 Also, a temperature sensor S1 is arranged in the sub duct 40. The temperature sensor S1 detects the temperature of the conditioned air sucked from the suction ports 30A and 30B. The detection data of the temperature sensor S1 is output to the control unit 50.
　操作パネル（図示せず）には、空調に関する種々の指令（設定）が入力される。操作パネルによって、車室２全体空間を空調する全体空調モード、又は、前席空間を優先的に空調するゾーン空調モードが選択できる。なお、ゾーン空調モードでは、運転席側及び助手席側、運転席側のみ、助手席側のみの三種類のゾーンを指定できる。 Various commands (settings) related to air conditioning are input to the operation panel (not shown). By the operation panel, an overall air conditioning mode for air-conditioning the entire space of the passenger compartment 2 or a zone air conditioning mode for preferentially air-conditioning the front seat space can be selected. In the zone air-conditioning mode, three types of zones can be specified: the driver side, the passenger side, the driver side only, and the passenger side only.
　制御部５０は、操作パネルからの指令等によって空気調和装置１１の動作や選択ドア４１、ベント吹出口選択ドア６０、フット吹出口選択ドア６１及び吸込口選択ドア６２の選択位置を制御する。例えば、制御部５０は、全体空調モードが選択されると、ベント吹出口選択ドア６０、フット吹出口選択ドア６１及び吸込口選択ドア６２をそれぞれ中間位置に設定すると共に選択ドア４１を閉じて、インストルメントパネル３の近くの温度センサ（図示せず）を利用して空調風の吹き出し温度等を制御する。一方、制御部５０は、ゾーン空調モードが選択されると、選択ドア４１を開いて、サブダクト４０内の温度センサＳ１を利用して空調風の吹き出し温度等を制御する。制御部５０は、ゾーン空調モードでの指定領域（運転席側及び助手席側、運転席側のみ、助手席側のみ）に応じてベント吹出口選択ドア６０、フット吹出口選択ドア６１及び吸込口選択ドア６２の位置を制御する。 The control unit 50 controls the operation of the air conditioner 11 and the selection positions of the selection door 41, the vent outlet selection door 60, the foot outlet selection door 61, and the suction inlet selection door 62 according to a command from the operation panel. For example, when the overall air conditioning mode is selected, the control unit 50 sets the vent outlet selection door 60, the foot outlet selection door 61, and the inlet selection door 62 to the intermediate positions and closes the selection door 41, A temperature sensor (not shown) in the vicinity of the instrument panel 3 is used to control the blowout temperature of the conditioned air. On the other hand, when the zone air-conditioning mode is selected, the control unit 50 opens the selection door 41 and controls the air-conditioning air blowing temperature and the like using the temperature sensor S1 in the sub duct 40. The control unit 50 determines whether the vent air outlet selection door 60, the foot air outlet selection door 61, and the air inlet according to the designated area in the zone air-conditioning mode (driver seat side and passenger seat side, driver seat side only, passenger seat side only). The position of the selection door 62 is controlled.
　上述した空気調和システム１０Ａの動作を説明する。空気調和装置１１が駆動されると、送風機１７によって外気導入口１４や内気導入口１５から空気がメインダクト１３内に吸い込まれる。吸い込まれた空気は、エバポレータ１８及びヒータコア１９によって所望温度の空調風にされ、その空調風が少なくとも一つの吹出口２１，２２ａ，２２ｂ，２３ａ，２３ｂ（例えば、ベント吹出口２２ａ，２２ｂ）から車室２内に吹き出される。 The operation of the above-described air conditioning system 10A will be described. When the air conditioner 11 is driven, air is sucked into the main duct 13 from the outside air inlet 14 and the inside air inlet 15 by the blower 17. The sucked air is converted into conditioned air at a desired temperature by the evaporator 18 and the heater core 19, and the conditioned air is supplied to the vehicle from at least one outlet 21, 22 a, 22 b, 23 a, 23 b (for example, vent outlet 22 a, 22 b). It is blown out into the chamber 2.
　全体空調モードでは、選択ドア４１が閉じられる。これにより、吸込口３０Ａ及び３０Ｂから空調風は吸い込まれない。従って、空気調和装置１１によって車室２内に吹き出された空調風は、車室２内のほぼ全域に行き渡る流れを形成し、車室２全体が空調される。 In the general air conditioning mode, the selection door 41 is closed. Thereby, the conditioned air is not sucked from the suction ports 30A and 30B. Therefore, the conditioned air blown into the passenger compartment 2 by the air conditioner 11 forms a flow that reaches almost the entire interior of the passenger compartment 2, and the entire passenger compartment 2 is air-conditioned.
　ゾーン空調モード（運転席側及び助手席側）では、選択ドア４１が開かれる。また、吸込口選択ドア６２、ベント吹出口選択ドア６０及びフット吹出口選択ドア６１が中間位置に設定される。これにより、図２に示されるように、空調モードの他に設定される空調風の吹出モードがベントモードの場合は、運転席側ベント吹出口２２ａ及び助手席側ベント吹出口２２ｂの双方から空調風が車室２内に吹き出される。一方、吹出モードがフットモードの場合は、運転席側フット吹出口２３ａ及び助手席側フット吹出口２３ｂの双方から空調風が車室２内に吹き出される。 In the zone air-conditioning mode (driver seat side and passenger seat side), the selection door 41 is opened. Moreover, the suction inlet selection door 62, the vent blower outlet selection door 60, and the foot blower outlet selection door 61 are set to an intermediate position. Accordingly, as shown in FIG. 2, when the air-conditioning air blowing mode set in addition to the air-conditioning mode is the vent mode, the air-conditioning is performed from both the driver seat side vent air outlet 22a and the passenger seat side vent air outlet 22b. Wind is blown into the passenger compartment 2. On the other hand, when the blowing mode is the foot mode, conditioned air is blown into the passenger compartment 2 from both the driver's seat side foot outlet 23a and the passenger's seat side foot outlet 23b.
　車室２内に吹き出された空調風は、送風機１７の吸引力によって、運転席側吸込口３０Ａ及び助手席側吸込口３０Ｂの双方から吸い込まれる。吸い込まれた空調風は、サブダクト４０を通って空調ユニット１２に戻される。空調風は運転席側フロントシート４上の乗員及び助手席側フロントシート４上の乗員の周辺を集中的（優先的）に流れて吸込口３０Ａ及び３０Ｂから回収される。また、吸込口３０Ａ及び３０Ｂより後方の車室空間への空調風の流れも抑制される。この結果、車室２内の運転席側フロントシート４及び助手席側フロントシート４の周囲にゾーン空調領域が形成される。 The conditioned air blown into the passenger compartment 2 is sucked from both the driver seat side suction port 30A and the passenger seat side suction port 30B by the suction force of the blower 17. The sucked conditioned air is returned to the air conditioning unit 12 through the sub duct 40. The conditioned air flows intensively (preferentially) around the passenger on the driver's seat side front seat 4 and the passenger on the passenger seat side front seat 4 and is collected from the suction ports 30A and 30B. Moreover, the flow of the conditioned air to the passenger compartment space behind the suction ports 30A and 30B is also suppressed. As a result, a zone air-conditioning region is formed around the driver seat side front seat 4 and the passenger seat side front seat 4 in the passenger compartment 2.
　ゾーン空調モード（運転席側のみ）では、選択ドア４１が開かれる。また、吸込口選択ドア６２、ベント吹出口選択ドア６０及びフット吹出口選択ドア６１が運転席側位置に設定される。これにより、図４に示されるように、ベントモードの場合は、運転席側ベント吹出口２２ａのみから空調風が車室２内に吹き出される。一方、フットモードの場合は、運転席側フット吹出口２３ａのみから空調風が車室２内に吹き出される。 In the zone air conditioning mode (driver's side only), the selection door 41 is opened. Moreover, the suction inlet selection door 62, the vent outlet selection door 60, and the foot outlet selection door 61 are set to the driver's seat side position. Thereby, as shown in FIG. 4, in the vent mode, the conditioned air is blown into the passenger compartment 2 only from the driver's seat side vent outlet 22a. On the other hand, in the foot mode, conditioned air is blown into the passenger compartment 2 only from the driver's seat side foot outlet 23a.
　車室２内に吹き出された空調風は、送風機１７の吸引力によって、運転席側吸込口３０Ａからのみ吸い込まれる。吸い込まれた空調風は、サブダクト４０を通って空調ユニット１２に戻される。空調風は運転席側フロントシート４上の乗員の周辺を集中的（優先的）に流れて吸込口３０Ａから回収される。また、吸込口３０Ａより後方の車室空間への流れも抑制される。この結果、車室２内の運転席側フロントシート４の周囲にゾーン空調領域が形成される。 The conditioned air blown into the passenger compartment 2 is sucked only from the driver seat side suction port 30 </ b> A by the suction force of the blower 17. The sucked conditioned air is returned to the air conditioning unit 12 through the sub duct 40. The conditioned air flows intensively (preferentially) around the passenger on the driver's seat side front seat 4 and is collected from the suction port 30A. Moreover, the flow to the passenger compartment space behind the suction port 30A is also suppressed. As a result, a zone air-conditioning region is formed around the driver seat side front seat 4 in the passenger compartment 2.
　ゾーン空調モード（助手席側のみ）では、吸込選択ドア４１が開かれる。また、吸込口選択ドア６２、ベント吹出口選択ドア６０及びフット吹出口選択ドア６１が助手席側位置に設定される。これにより、図５に示されるように、ベントモードの場合は、助手席側ベント吹出口２２ｂのみから空調風が車室２内に吹き出される。一方、フットモードの場合は、助手席側フット吹出口２３ｂのみから空調風が車室２内に吹き出される。 In the zone air conditioning mode (passenger side only), the suction selection door 41 is opened. Moreover, the suction inlet selection door 62, the vent outlet selection door 60, and the foot outlet selection door 61 are set to a passenger seat side position. Thus, as shown in FIG. 5, in the vent mode, the conditioned air is blown into the passenger compartment 2 only from the passenger seat side vent outlet 22b. On the other hand, in the foot mode, conditioned air is blown into the passenger compartment 2 only from the passenger seat side foot outlet 23b.
　車室２内に吹き出された空調風は、送風機１７の吸引力によって、助手席側吸込口３０Ｂからのみ吸い込まれる。吸い込まれた空調風は、サブダクト４０を通って空調ユニット１２に戻される。空調風は助手席側フロントシート４上の乗員の周辺を集中的（優先的）に流れて吸込口３０Ｂより回収される。また、吸込口３０Ｂより後方の車室空間への流れも抑制される。この結果、車室２内の助手席側フロントシート４の周囲にゾーン空調領域が形成される。 The conditioned air blown into the passenger compartment 2 is sucked only from the passenger seat side suction port 30 </ b> B by the suction force of the blower 17. The sucked conditioned air is returned to the air conditioning unit 12 through the sub duct 40. The conditioned air flows intensively (preferentially) around the passenger on the passenger seat side front seat 4 and is collected from the inlet 30B. Moreover, the flow to the passenger compartment space behind the suction port 30B is also suppressed. As a result, a zone air-conditioning region is formed around the front passenger seat 4 in the passenger compartment 2.
　ゾーン空調モード（運転席側及び助手席側、運転席側のみ、助手席側のみ）では、空調ユニット１２のエバポレータ１８やヒータコア１９を利用して所望温度の空調風が生成されるので、ゾーン空調専用の熱交換部の設置が必須ではなく、システムの単純化や低コスト化を実現できる。吸込口３０Ａ及び３０Ｂから吸い込まれた空調風は、空気調和装置１１に戻される全経路にわたってサブダクト４０内を流れ、熱損失が極力抑制されつつ空気調和装置１１に戻される。この結果、空気調和装置１１の空調負荷が低減する。また、吸込口３０Ａ及び３０Ｂから吸い込まれた空調風は、車室２内に一切吹き出されないので、所望温度でない循環流が乗員周辺に形成されることがない。さらに、吸込口選択ドア６２によって、吸込口３０Ａ，３０Ｂのどちら（双方を含む）から空調風を吸い込むかを選択できるので、上述したようにゾーン空調領域を可変制御できる。 In the zone air-conditioning mode (driver seat side and passenger seat side, driver seat side only, passenger seat side only), the conditioned air at the desired temperature is generated using the evaporator 18 and the heater core 19 of the air conditioning unit 12. Installation of a dedicated heat exchange unit is not essential, and simplification and cost reduction of the system can be realized. The conditioned air sucked from the suction ports 30 </ b> A and 30 </ b> B flows through the sub duct 40 over the entire path returned to the air conditioner 11, and is returned to the air conditioner 11 while suppressing heat loss as much as possible. As a result, the air conditioning load of the air conditioner 11 is reduced. In addition, since the conditioned air sucked from the suction ports 30A and 30B is not blown into the passenger compartment 2 at all, a circulation flow not having a desired temperature is not formed around the passenger. Furthermore, since the suction port selection door 62 can select from which of the suction ports 30A and 30B (including both) the conditioned air is sucked, the zone air conditioning region can be variably controlled as described above.
　従って、空気調和システム１０Ａによれば、システム構成の単純化や低コスト化を実現できる。また、空調負荷の低減による省エネルギー化を実現しつつ快適なゾーン空調を行うことができ、かつ、ゾーン空調領域を簡単に可変制御できる。さらに、ゾーン空調によって即冷性及び即暖性が向上される。 Therefore, according to the air conditioning system 10A, the system configuration can be simplified and the cost can be reduced. In addition, it is possible to perform comfortable zone air-conditioning while realizing energy saving by reducing the air-conditioning load, and to easily variably control the zone air-conditioning region. Furthermore, immediate cooling and immediate warming are improved by zone air conditioning.
　空気調和装置が既に搭載されている車両では吸込口３０Ａ及び３０Ｂ並びにサブダクト４０等を設置するだけで上記実施形態を実現でき、後付け設置が簡単に行える。 In a vehicle already equipped with an air conditioner, the above embodiment can be realized simply by installing the suction ports 30A and 30B, the sub duct 40, etc., and retrofit installation can be easily performed.
　また、サブダクト４０の内部とメインダクト１３の内部との連通を遮蔽可能な選択ドア４１が設けられたので、選択ドア４１によって全体空調モード及びゾーン空調モードを選択的に実行できる。しかも、選択ドア４１の動作を制御するだけで、全体空調モードとゾーン空調モードとを容易に切り替えることができる。 Further, since the selection door 41 capable of shielding the communication between the inside of the sub duct 40 and the inside of the main duct 13 is provided, the entire air conditioning mode and the zone air conditioning mode can be selectively executed by the selection door 41. Moreover, it is possible to easily switch between the overall air conditioning mode and the zone air conditioning mode simply by controlling the operation of the selection door 41.
　空調風の吸い込みは、吸込口選択ドア６２によって、運転席側吸込口３０Ａ及び助手席側吸込口３０Ｂの双方、又は、運転席側吸込口３０Ａ及び助手席側吸込口３０Ｂのいずれか一方から選択的に行われる。従って、ゾーン空調モードでは、三つのゾーン空調領域（運転席側及び助手席側、運転席側のみ、助手席側のみ）から一つの領域を選択できる。 The suction of air-conditioned air is selected from either the driver seat side suction port 30A and the passenger seat side suction port 30B, or either the driver seat side suction port 30A or the passenger seat side suction port 30B by the suction port selection door 62. Done. Therefore, in the zone air-conditioning mode, one area can be selected from the three zone air-conditioning areas (driver seat side and passenger seat side, driver seat side only, passenger seat side only).
　空気調和装置１１では、吸込口選択器（吸込口選択ドア６２）と吹出口選択器（ベント吹出口選択ドア６０又はフット吹出口選択ドア６１）とによって、互いに対応する吸込口及び吹出口（運転席側吸込口３０Ａ、及び、運転席ベント吹出口２２ａ又は運転席フット吹出口２３ａ：助手席側吸込口３０Ｂ、及び、助手席側ベント吹出口２２ｂ又は助手席側フット吹出口２３ｂ）が連動的に選択され得る。従って、ゾーン空調に寄与しない空調風の空調ユニット１２からの吹き出しが抑制され、ゾーン空調に有効に寄与する空調風のみが空調ユニット１２から吹き出される。この結果、空気調和装置１１の空調負荷が更に低減され、省エネルギー化を実現できる。 In the air conditioner 11, the suction inlet and the outlet (operating) corresponding to each other by the inlet selector (suction inlet selection door 62) and the outlet selector (the vent outlet selecting door 60 or the foot outlet selecting door 61). The seat side suction port 30A and the driver seat vent outlet 22a or the driver seat foot outlet 23a: the passenger seat side inlet 30B and the passenger seat side vent outlet 22b or the passenger seat side foot outlet 23b) are interlocked. Can be selected. Therefore, the blowing of the conditioned air that does not contribute to the zone air conditioning from the air conditioning unit 12 is suppressed, and only the conditioned air that effectively contributes to the zone air conditioning is blown out from the air conditioning unit 12. As a result, the air conditioning load of the air conditioner 11 is further reduced, and energy saving can be realized.
　また、サブダクト４０の他端が、送風機１７より上流でメインダクト１３に接続されているので、送風機１７の吸込力を利用して空調風を吸込口３０Ａ及び３０Ｂから吸い込むことができる。このため、吸込口３０Ａ及び３０Ｂからの吸い込みのためだけに送風機を別途設ける必要がない。この結果、システム構成の更なる単純化や低コスト化を実現できる。 Also, since the other end of the sub duct 40 is connected to the main duct 13 upstream from the blower 17, the conditioned air can be sucked from the suction ports 30A and 30B by using the suction force of the blower 17. For this reason, it is not necessary to separately provide a blower only for suction from the suction ports 30A and 30B. As a result, further simplification and cost reduction of the system configuration can be realized.
　また、吸込口３０Ａ及び３０Ｂは、フロントシート４に設けられている。フロントシート４は、必ず設けられる既存の部品であり、吸込口３０Ａ及び３０Ｂを配置するのに最も適しており、吸込口３０Ａ及び３０Ｂを設置し易い。 Further, the suction ports 30A and 30B are provided in the front seat 4. The front seat 4 is an existing component that is always provided, and is most suitable for disposing the suction ports 30A and 30B, and the suction ports 30A and 30B are easy to install.
　また、吸込口３０Ａ及び３０Ｂは、シートバック４ｂの上部に設けられている。ベント吹出口２２ａ及び２２ｂから吹き出された空調風（暖風、冷風）の気流は、遮蔽物のない車室２の上方に集まり易い。従って、シートバック４ｂの上部に設けられた吸込口３０Ａ及び３０Ｂによって、効率良く空調風を吸い込むことができ、空調風の回収率が向上する。 Further, the suction ports 30A and 30B are provided in the upper part of the seat back 4b. Airflows of conditioned air (warm air, cold air) blown out from the vent outlets 22a and 22b are likely to gather above the passenger compartment 2 without a shield. Therefore, the conditioned air can be efficiently sucked by the suction ports 30A and 30B provided in the upper part of the seat back 4b, and the recovery rate of the conditioned air is improved.
　また、吸込口３０Ａ及び３０Ｂから吸い込まれた空調風の温度を検出する温度センサＳ１が備けられている。従って、ゾーン空調モードでは、乗員周辺を実際に通過した空調風の温度に基づいて空気調和装置１１から吹き出される空調風の温度等を制御することができ、空調温度が的確に制御され得る。 Further, a temperature sensor S1 for detecting the temperature of the conditioned air sucked from the suction ports 30A and 30B is provided. Therefore, in the zone air-conditioning mode, the temperature of the air-conditioning air blown from the air conditioner 11 can be controlled based on the temperature of the air-conditioning air that has actually passed around the passenger, and the air-conditioning temperature can be accurately controlled.
（第２実施形態）
　図６及び図７は第２実施形態の空気調和システム１０Ｂを示している。図６及び図７に示されるように、空気調和システム１０Ｂでは、サブダクト４０の他端の接続位置が上述した第１実施形態の空気調和システム１０Ａと異なる。サブダクト４０の他端は、送風機１７とエバポレータ１８との間でメインダクト１３に接続されている。そして、サブダクト４０には、吸込口３０Ａ及び３０Ｂから空気を吸い込むサブ送風機４２が設けられている。サブ送風機４２は、制御部５０によって制御される。 (Second Embodiment)
6 and 7 show an air conditioning system 10B of the second embodiment. As shown in FIGS. 6 and 7, in the air conditioning system 10B, the connection position of the other end of the sub-duct 40 is different from the air conditioning system 10A of the first embodiment described above. The other end of the sub duct 40 is connected to the main duct 13 between the blower 17 and the evaporator 18. The sub duct 40 is provided with a sub blower 42 that sucks air from the suction ports 30A and 30B. The sub blower 42 is controlled by the control unit 50.
　第１実施形態の構成と同一又は同等のその他の構成には同一符号を付して、重複説明を省略する。 Other configurations that are the same as or equivalent to those of the first embodiment are denoted by the same reference numerals, and redundant description is omitted.
　上述した空気調和システム１０Ｂの動作を説明する。空気調和装置１１が駆動されると、送風機１７によって外気導入口１４や内気導入口１５から空気がメインダクト１３内に吸い込まれる。吸い込まれた空気は、エバポレータ１８及びヒータコア１９によって所望温度の空調風にされ、その空調風が少なくとも一つの吹出口２１，２２ａ，２２ｂ，２３ａ，２３ｂ（例えば、ベント吹出口２２ａ，２２ｂ）から車室２内に吹き出される。 The operation of the air conditioning system 10B described above will be described. When the air conditioner 11 is driven, air is sucked into the main duct 13 from the outside air inlet 14 and the inside air inlet 15 by the blower 17. The sucked air is converted into conditioned air at a desired temperature by the evaporator 18 and the heater core 19, and the conditioned air is supplied to the vehicle from at least one outlet 21, 22 a, 22 b, 23 a, 23 b (for example, vent outlet 22 a, 22 b). It is blown out into the chamber 2.
　全体空調モードでは、選択ドア４１が閉じられ、サブ送風機４２は駆動されない。これにより、吸込口３０Ａ，３０Ｂから空調風は吸い込まれない。従って、空気調和装置１１によって車室２内に吹き出された空調風は、車室２内のほぼ全域に行き渡る流れを形成し、車室２全体が空調される。 In the overall air conditioning mode, the selection door 41 is closed and the sub blower 42 is not driven. Thereby, the conditioned air is not sucked from the suction ports 30A and 30B. Therefore, the conditioned air blown into the passenger compartment 2 by the air conditioner 11 forms a flow that reaches almost the entire interior of the passenger compartment 2, and the entire passenger compartment 2 is air-conditioned.
　ゾーン空調モード（運転席側及び助手席側）では、選択ドア４１が開かれ、サブ送風機４２が駆動される。これにより、サブ送風機４２の吸込力によって、吸込口３０Ａ，３０Ｂから空調風が吸い込まれる。従って、空気調和装置１１から車室２内に吹き出された空調風は、運転席側吸込口３０Ａ及び助手席側吸込口３０Ｂの双方から吸い込まれる。吸い込まれた空調風は、サブダクト４０を通って空調ユニット１２に戻される。空調風はフロントシート４上の乗員の周辺を集中的（優先的）に流れて吸込口３０Ａ及び３０Ｂによって回収される。吸込口３０Ａ及び３０Ｂより後方の車室空間への空調風の流れも抑制される。この結果、車室２内のフロントシート４の周囲にゾーン空調領域が形成される。 In the zone air conditioning mode (driver's seat side and passenger's seat side), the selection door 41 is opened and the sub-blower 42 is driven. Accordingly, the conditioned air is sucked from the suction ports 30 </ b> A and 30 </ b> B by the suction force of the sub blower 42. Therefore, the conditioned air blown into the passenger compartment 2 from the air conditioner 11 is sucked from both the driver seat side suction port 30A and the passenger seat side suction port 30B. The sucked conditioned air is returned to the air conditioning unit 12 through the sub duct 40. The conditioned air flows intensively (preferentially) around the passenger on the front seat 4 and is collected by the suction ports 30A and 30B. The flow of conditioned air to the passenger compartment space behind the suction ports 30A and 30B is also suppressed. As a result, a zone air-conditioning area is formed around the front seat 4 in the passenger compartment 2.
　また、ゾーン空調モード（運転席側のみ、又は、助手席側のみ）の場合にも、第１実施形態で説明したように、ベント吹出口選択ドア６０、フット吹出口選択ドア６１及び吸込口選択ドア６２の位置が制御され、第１実施形態と同様の空調風の流れが形成される。 Also, in the case of the zone air-conditioning mode (only on the driver's seat side or on the passenger seat side), as described in the first embodiment, the vent outlet selection door 60, the foot outlet selection door 61, and the inlet selection The position of the door 62 is controlled, and a flow of conditioned air similar to that of the first embodiment is formed.
　従って、空気調和システム１０Ｂによれば、第１実施形態と同様に、システム構成の単純化や低コスト化を実現できる。また、空調負荷の低減による省エネルギー化を実現しつつ快適なゾーン空調を行うことができる。また、ゾーン空調によって即冷性及び即暖性が向上される。さらに、ゾーン空調領域を簡単に可変制御できる。 Therefore, according to the air conditioning system 10B, simplification of the system configuration and cost reduction can be realized as in the first embodiment. In addition, comfortable zone air conditioning can be performed while realizing energy saving by reducing the air conditioning load. Moreover, immediate cooling and immediate warming are improved by zone air conditioning. Furthermore, the zone air-conditioning area can be easily variably controlled.
　また、選択ドア４１に加えてサブ送風機４２が設けられたので、選択ドア４１及びサブ送風機４２を制御することで全体空調モード及びゾーン空調モードを選択的に実行できる。 Further, since the sub blower 42 is provided in addition to the selection door 41, the entire air conditioning mode and the zone air conditioning mode can be selectively executed by controlling the selection door 41 and the sub blower 42.
　さらに、サブ送風機４２を制御することで、空気調和装置１１の送風量とは独立して吸込口３０Ａ及び３０Ｂの吸込量を調整できる。 Furthermore, by controlling the sub blower 42, the suction amount of the suction ports 30A and 30B can be adjusted independently of the blow amount of the air conditioner 11.
（第３実施形態）
　図８～図１０は第３実施形態の空気調和システム１０Ｃを示している。図８～図１０に示されるように、空気調和システム１０Ｃでは、サブダクト４０が直接メインダクト１３に接続されていない点が上述した第１実施形態の空気調和システム１０Ａと異なる。また、この構成に伴って、サブダクト４０に第２実施形態で説明したサブ送風機４２が設けられていると共に、メインダクト１３の内気導入口１５の近くに補助内気導入口２７が設けられている点も上述した第１実施形態の空気調和システム１０Ａと異なる。 (Third embodiment)
8 to 10 show an air conditioning system 10C of the third embodiment. As shown in FIGS. 8 to 10, the air conditioning system 10C is different from the air conditioning system 10A of the first embodiment described above in that the sub duct 40 is not directly connected to the main duct 13. With this configuration, the sub duct 40 is provided with the sub blower 42 described in the second embodiment, and the auxiliary internal air introduction port 27 is provided near the internal air introduction port 15 of the main duct 13. Is also different from the air conditioning system 10A of the first embodiment described above.
　第１実施形態の構成と同一又は同等のその他の構成には同一符号を付して、重複説明を省略する。なお、サブ送風機４２については第２実施形態で説明したので、サブ送風機４２についての説明も省略する。 Other configurations that are the same as or equivalent to those of the first embodiment are denoted by the same reference numerals, and redundant description is omitted. Since the sub blower 42 has been described in the second embodiment, the description of the sub blower 42 is also omitted.
　本実施形態では、ダクト４０の他端は、空調ユニット１２に接続されていない。ダクト４０の他端の開口部４０ａは、空調ユニット１２の内気導入口１５と補助内気導入口２７の近傍で、内気導入口１５及び補助内気導入口２７に向けて開口されている。従って、本実施形態においては、第１実施形態の選択ドア４１が設けられておらず、その代わりに、第２実施形態で説明したサブ送風機４２が設けられている。サブ送風機４２は、制御部５０によって制御される。 In the present embodiment, the other end of the duct 40 is not connected to the air conditioning unit 12. The opening 40 a at the other end of the duct 40 is opened toward the inside air introduction port 15 and the auxiliary room air introduction port 27 in the vicinity of the room air introduction port 15 and the auxiliary room air introduction port 27 of the air conditioning unit 12. Therefore, in this embodiment, the selection door 41 of 1st Embodiment is not provided, but the sub air blower 42 demonstrated in 2nd Embodiment is provided instead. The sub blower 42 is controlled by the control unit 50.
　上述した空気調和システム１０Ｃの動作を説明する。空気調和装置１１が駆動されると、送風機１７によって外気導入口１４や内気導入口１５から空気がメインダクト１３内に吸い込まれる。吸い込まれた空気は、エバポレータ１８及びヒータコア１９によって所望温度の空調風にされ、その空調風が少なくとも一つの吹出口２１，２２ａ，２２ｂ，２３ａ，２３ｂ（例えば、ベント吹出口２２ａ，２２ｂ）から車室２内に吹き出される。 The operation of the above-described air conditioning system 10C will be described. When the air conditioner 11 is driven, air is sucked into the main duct 13 from the outside air inlet 14 and the inside air inlet 15 by the blower 17. The sucked air is converted into conditioned air at a desired temperature by the evaporator 18 and the heater core 19, and the conditioned air is supplied to the vehicle from at least one outlet 21, 22 a, 22 b, 23 a, 23 b (for example, vent outlet 22 a, 22 b). It is blown out into the chamber 2.
　全体空調モードでは、サブ送風機４２は駆動されない。これにより、吸込口３０Ａ，３０Ｂから空調風は吸い込まれない。従って、空気調和装置１１よって車室２内に吹き出された空調風は、車室２内のほぼ全域に行き渡る流れを形成し、車室２全体が空調される。 In the overall air conditioning mode, the sub blower 42 is not driven. Thereby, the conditioned air is not sucked from the suction ports 30A and 30B. Therefore, the conditioned air blown into the passenger compartment 2 by the air conditioner 11 forms a flow that spreads over almost the entire interior of the passenger compartment 2, and the entire passenger compartment 2 is air-conditioned.
　ゾーン空調モード（運転席側及び助手席側）では、サブ送風機４２が駆動される。これにより、サブ送風機４２の吸込力によって、吸込口３０Ａ，３０Ｂから空調風が吸い込まれる。従って、空気調和装置１１から車室２内に吹き出された空調風は、運転席側吸込口３０Ａ及び助手席側吸込口３０Ｂの双方から吸い込まれる。吸い込まれた空調風は、サブダクト４０を通って空調ユニット１２の近くで開口部４０ａから吹き出され、その直後に内気導入口１５又は補助内気導入孔２７から空調ユニット１２内に吸い込まれる。 In the zone air conditioning mode (driver seat side and passenger seat side), the sub blower 42 is driven. Accordingly, the conditioned air is sucked from the suction ports 30 </ b> A and 30 </ b> B by the suction force of the sub blower 42. Therefore, the conditioned air blown into the passenger compartment 2 from the air conditioner 11 is sucked from both the driver seat side suction port 30A and the passenger seat side suction port 30B. The sucked conditioned air is blown out from the opening 40a near the air conditioning unit 12 through the sub duct 40, and immediately after that, is sucked into the air conditioning unit 12 from the inside air introduction port 15 or the auxiliary inside air introduction hole 27.
　ここで、内気導入モードでは、開口部４０ａから吹き出された送風は内気導入口１５から空調ユニット１２内に吸い込まれる。このとき、補助内気導入口２７は補助吸込ドア２８によって閉じられている。一方、外気導入モードでは、開口部４０ａから吹き出された送風は補助内気導入口２７から空調ユニット１２内に吸い込まれる。このとき、補助内気導入口２７は補助吸込ドア２８によって開かれている。 Here, in the inside air introduction mode, the air blown from the opening 40a is sucked into the air conditioning unit 12 from the inside air introduction port 15. At this time, the auxiliary inside air inlet 27 is closed by the auxiliary suction door 28. On the other hand, in the outside air introduction mode, the air blown from the opening 40 a is sucked into the air conditioning unit 12 from the auxiliary inside air introduction port 27. At this time, the auxiliary inside air inlet 27 is opened by the auxiliary suction door 28.
　図９に示されるように、空調風はフロントシート４上の乗員の周辺を集中的（優先的）に流れて吸込口３０Ａ及び３０Ｂから回収される。吸込口３０Ａ及び３０Ｂより後方の車室空間への流れも抑制される。この結果、車室２内のフロントシート４の周囲にゾーン空調領域が形成される。 As shown in FIG. 9, the conditioned air flows intensively (preferentially) around the passenger on the front seat 4 and is collected from the suction ports 30A and 30B. The flow to the passenger compartment space behind the suction ports 30A and 30B is also suppressed. As a result, a zone air-conditioning area is formed around the front seat 4 in the passenger compartment 2.
　また、ゾーン空調モード（運転席側のみ、又は、助手席側のみ）の場合にも、第１実施形態で説明したように、ベント吹出口選択ドア６０、フット吹出口選択ドア６１及び吸込口選択ドア６２の位置が制御され、第１実施形態と同様の空調風の流れが形成される。 Also, in the case of the zone air-conditioning mode (only on the driver's seat side or on the passenger seat side), as described in the first embodiment, the vent outlet selection door 60, the foot outlet selection door 61, and the inlet selection The position of the door 62 is controlled, and a flow of conditioned air similar to that of the first embodiment is formed.
　ゾーン空調モードでは、空調ユニット１２のエバポレータ１８やヒータコア１９を利用して所望温度の空調風が生成されるので、ゾーン空調専用の熱交換部の設置が必須ではなく、システムの単純化や低コスト化を実現できる。吸込口３０Ａ及び３０Ｂから吸い込まれた空調風は、空気調和装置１１に戻される経路の大部分でサブダクト４０内を流れるので、熱損失が極力抑制されつつ空気調和装置１１に戻される。この結果、空気調和装置１１の空調負荷が低減する。 In the zone air-conditioning mode, air-conditioning air having a desired temperature is generated using the evaporator 18 and the heater core 19 of the air-conditioning unit 12, so that it is not essential to install a heat exchanging unit dedicated to zone air-conditioning, simplifying the system and reducing the cost. Can be realized. The conditioned air sucked from the suction ports 30 </ b> A and 30 </ b> B flows through the sub duct 40 in most of the path returned to the air conditioner 11, and is returned to the air conditioner 11 while suppressing heat loss as much as possible. As a result, the air conditioning load of the air conditioner 11 is reduced.
また、吸込口３０Ａ及び３０Ｂから吸い込まれた空調風は、車室２内に一切吹き出されないので、所望温度でない循環流が乗員周辺に形成されることがない。さらに、吸込口選択ドア６２によって、吸込口３０Ａ，３０Ｂのどちら（双方を含む）から空調風を吸い込むかを選択できるので、上述したようにゾーン空調領域を可変制御できる。 In addition, since the conditioned air sucked from the suction ports 30A and 30B is not blown into the passenger compartment 2 at all, a circulation flow not having a desired temperature is not formed around the passenger. Furthermore, since the suction port selection door 62 can select from which of the suction ports 30A and 30B (including both) the conditioned air is sucked, the zone air conditioning region can be variably controlled as described above.
　従って、空気調和システム１０Ｃによれば、システム構成の単純化や低コスト化を実現できる。また、空調負荷の低減による省エネルギー化を実現しつつ快適なゾーン空調を行うことができ、かつ、ゾーン空調領域を簡単に可変制御できる。さらに、ゾーン空調によって即冷性及び即暖性が向上される。 Therefore, according to the air conditioning system 10C, the system configuration can be simplified and the cost can be reduced. In addition, it is possible to perform comfortable zone air-conditioning while realizing energy saving by reducing the air-conditioning load, and to easily variably control the zone air-conditioning region. Furthermore, immediate cooling and immediate warming are improved by zone air conditioning.
　空気調和装置が既に搭載されている車両では吸込口３０Ａ及び３０Ｂ並びにサブダクト４０やサブ送風機４２等を設置するだけで上記実施形態を実現でき、後付け設置が簡単に行える。 In a vehicle in which an air conditioner is already mounted, the above embodiment can be realized simply by installing the suction ports 30A and 30B, the sub duct 40, the sub blower 42, and the like, and retrofit installation can be easily performed.
　サブ送風機４２を制御することで全体空調モードとゾーン空調モードとを選択的に行うことができ、その切り替えを容易に制御できる。 全体 By controlling the sub blower 42, the entire air conditioning mode and the zone air conditioning mode can be selectively performed, and the switching can be easily controlled.
　また、サブダクト４０の開口部４０ａは、空調ユニット１２の内気導入口１５（補助内気導入孔２７）の近傍に配置され、かつ、内気導入口１５（補助内気導入孔２７）に向けて開口されている。従って、開口部４０ａから吹き出された送風は、空調ユニット１２の送風機１７の吸込力とサブダクト４０のサブ送風機４２の吹出力との相乗作用によって、確実、かつ、迅速に空調ユニット１２内に回収される。 The opening 40a of the sub duct 40 is disposed in the vicinity of the inside air introduction port 15 (auxiliary inside air introduction hole 27) of the air conditioning unit 12, and is opened toward the inside air introduction port 15 (auxiliary inside air introduction hole 27). Yes. Therefore, the air blown out from the opening 40a is reliably and quickly collected in the air conditioning unit 12 by the synergistic action of the suction force of the blower 17 of the air conditioning unit 12 and the blowing output of the sub blower 42 of the sub duct 40. The
　また、空調ユニット１２は、補助内気導入口２７と補助吸込ドア２８とを有している。従って、開口部４０ａから吹き出された送風を補助内気導入口２７によって空調ユニット１２内に回収できるので、外気導入時でもゾーン空調を行うことができる。 Further, the air conditioning unit 12 has an auxiliary inside air inlet 27 and an auxiliary suction door 28. Therefore, since the air blown from the opening 40a can be collected in the air conditioning unit 12 by the auxiliary inside air introduction port 27, zone air conditioning can be performed even when outside air is introduced.
　本実施形態では、空調ユニット１２のメインダクト１３に補助内気導入口２７を設けると共に補助内気導入口２７を開閉する補助吸込ドア２８が設けられたが、補助内気導入口２７及び補助吸込ドア２８が設けられなくてもよい。この場合、外気導入時にゾーン空調モードが選択された場合には、外気導入口１４及び内気導入口１５の双方を開くようにインテークドア１６ａ及び１６ｂが制御される。このようにすれば、補助内気導入口２７及び補助吸込ドア２８を設ける必要がなく、システム構成を単純化できる。 In the present embodiment, the auxiliary air inlet 27 is provided in the main duct 13 of the air conditioning unit 12 and the auxiliary air inlet 27 for opening and closing the auxiliary air inlet 27 is provided, but the auxiliary air inlet 27 and the auxiliary air door 28 are provided. It may not be provided. In this case, when the zone air-conditioning mode is selected when the outside air is introduced, the intake doors 16a and 16b are controlled to open both the outside air introduction port 14 and the inside air introduction port 15. In this way, it is not necessary to provide the auxiliary inside air inlet 27 and the auxiliary suction door 28, and the system configuration can be simplified.
　さらに、サブ送風機４２を制御することで、空気調和装置１１の送風量とは独立して吸込口３０Ａ及び３０Ｂの吸込量を調整できる。 Furthermore, by controlling the sub blower 42, the suction amount of the suction ports 30A and 30B can be adjusted independently of the blow amount of the air conditioner 11.
（変形例）
　上記実施形態では、フロントシート４上の乗員に対してゾーン空調でき、かつ、運転席側フロントシート４上の乗員と助手席側フロントシート４上の乗員とのそれぞれに対してゾーン空調領域を設定できる。さらに、リアシート５上の乗員に対してゾーン空調でき、かつ、右側リアシート５上の乗員と左側リアシート５上の乗員とのそれぞれに対してゾーン空調領域を設定してもよい。即ち、本変形例は、上記第１～３実施形態の何れかの構成に加えて、リアシート５の周辺に開口された複数の吸込口と、これらの複数の吸込口からの空調風を空気調和装置にサブダクトとを備え、かつ、リアシート５用のサブダクトに吸込口選択ドアを備えている。この構成によれば、フロントシート４上の乗員だけでなくリアシート５上の乗員に対してもゾーン空調領域を設定できる。本変形例は、ワンボックスカーなどの車室２の容積が大きい車両に特に有効である。 (Modification)

Furthermore, zone air conditioning may be set for each of the passengers on the right rear seat 5 and the passengers on the left rear seat 5, and the zone air conditioning may be performed for the passengers on the rear seat 5. That is, in this modified example, in addition to the configuration of any of the first to third embodiments, a plurality of suction openings opened around the rear seat 5 and conditioned air from these suction openings are air-conditioned. The apparatus includes a sub duct, and the sub duct for the rear seat 5 includes a suction port selection door. According to this configuration, the zone air conditioning region can be set not only for the passenger on the front seat 4 but also for the passenger on the rear seat 5. This modification is particularly effective for a vehicle having a large volume of the passenger compartment 2 such as a one-box car.

Providing the suction ports 30A to 30D around the seat 4 or 5 is easy to install later.
　さらに、ゾーン空調領域は、手動操作に基づいて設定されてもよいし、乗員検出器（例えば、着座センサ）の検出結果に基づいて自動設定されてもよい。 Furthermore, the zone air conditioning region may be set based on a manual operation, or may be automatically set based on a detection result of an occupant detector (for example, a seating sensor).
