Description

本発明は、旅客用の鉄道車両や大型バス等の車両に用いられる車両用空調システム関するものである。 The present invention relates to a vehicle air conditioner used in a vehicle of a railway vehicle or motor coach, etc. for passenger.

従来の車両用空調システムでは、車両の屋根に空気調和機が設けられ、客室の天井に空気調和機の吸い込み口と吹き出し口とが設けられる。
客室の空気がこのような車両用空調システムの暖房運転によって暖められる場合には、空気調和機の吹き出し口から吹き出された暖房気流は、客室の上方に溜まることとなる。そのため、座席等が設けられた客室の下方の空気の温度が低いままとなり、足下が寒いと乗客が感じてしまい、快適性が保たれなくなることがあった。
そこで、暖房気流が、客室の壁面に設けられた風路を通って床近傍から吹き出されることで、客室の空気が均一に暖められる車両用空調システムが提案されている(特許文献1参照)。
In a conventional vehicle air conditioning system, an air conditioner is provided on the roof of the vehicle, and an air inlet and a blowout port of the air conditioner are provided on the ceiling of the passenger cabin.

実施の形態1.
以下に、実施の形態1に係る車両用空調システムを説明する。
(車両用空調システムの構成)
まず、実施の形態1に係る車両用空調システムの構成について説明する。
図1は、実施の形態1に係る車両用空調システムの構成を示す図である。図1に示すように、車両用空調システム1は、空気調和機2と、横断流送風機3と、吸い込み口温度センサ4と、制御部5と、を少なくとも有する(なお、制御部5は、本発明における「制御手段」に相当する。)。
Embodiment 1 FIG.
The vehicle air conditioning system according to Embodiment 1 will be described below.
(Configuration of vehicle air conditioning system)
First, the configuration of the vehicle air conditioning system according to Embodiment 1 will be described.
1 is a diagram showing a configuration of a vehicle air conditioning system according to Embodiment 1. FIG. As shown in FIG. 1, the vehicle air conditioning system 1 includes at least an air conditioner 2, a cross flow blower 3, a suction port temperature sensor 4, and a control unit 5 (note that the control unit 5 is a main unit). This corresponds to “control means” in the invention.)

空気調和機2は、車両21の屋根22に設けられる。横断流送風機3は、車両21の客室23の天井24の裏側で且つ車両21の幅方向の略中央に設けられる(なお、客室23は、本発明における「車両内部の空間」に相当する。)。空気調和機2で空調される客室23の空気は、吸い込み口25から吸い込まれる。横断流送風機3の両側にはダクト(図示せず)が設けられ、空気調和機2で空調された空気は、ダクト(図示せず)を介して吹き出し口26から客室23へ吹き出される。吸い込み口25と吹き出し口26とは、天井24に設けられる。   The air conditioner 2 is provided on the roof 22 of the vehicle 21. The cross-flow blower 3 is provided on the back side of the ceiling 24 of the passenger cabin 23 of the vehicle 21 and substantially in the center in the width direction of the vehicle 21 (note that the passenger cabin 23 corresponds to the “space inside the vehicle” in the present invention). . Air in the guest room 23 that is air-conditioned by the air conditioner 2 is sucked from the suction port 25. Ducts (not shown) are provided on both sides of the cross flow blower 3, and the air conditioned by the air conditioner 2 is blown out from the outlet 26 to the cabin 23 via the duct (not shown). The inlet 25 and the outlet 26 are provided on the ceiling 24.

空気調和機2は、制御部5によって制御され、暖房運転や冷房運転等を行って客室23の空気を空調する。客室23の空気は、空気調和機の吸い込み気流を示す矢印41のように吸い込み口25から吸い込まれる。空気調和機2からの暖房気流や冷房気流は、空気調和機の吹き出し気流を示す矢印42のように客室23へ吹き出される。   The air conditioner 2 is controlled by the control unit 5 and air-conditions the air in the cabin 23 by performing a heating operation, a cooling operation, or the like. The air in the guest room 23 is sucked from the suction port 25 as indicated by an arrow 41 indicating the suction airflow of the air conditioner. The heating airflow and the cooling airflow from the air conditioner 2 are blown out to the passenger room 23 as indicated by an arrow 42 indicating a blown airflow of the air conditioner.

横断流送風機3は、その長手方向が車両21の長手方向に平行となるように設けられ、横断流送風機の動きを示す矢印43の方向、つまり車両21の幅方向に揺動可能である。また、天井24に設けられた吹き出し口27から横断流送風機の吹き出し気流を示す矢印44のように気流を客室23へ吹き出す。吹き出し口27は、車両21の幅方向の略中央に位置する。   The cross flow blower 3 is provided such that its longitudinal direction is parallel to the longitudinal direction of the vehicle 21, and can swing in the direction of an arrow 43 indicating the movement of the cross flow blower, that is, the width direction of the vehicle 21. In addition, an air flow is blown out to the cabin 23 as indicated by an arrow 44 indicating a blown air flow of the cross flow blower from a blowout port 27 provided on the ceiling 24. The air outlet 27 is located at the approximate center in the width direction of the vehicle 21.

吸い込み口温度センサ4は、吸い込み口25の近傍に設けられ、吸い込み口25から吸い込まれる空気調和機2の吸い込み気流の温度を検出する。吸い込み口温度センサ4は、例えばサーミスタ等からなる。   The suction port temperature sensor 4 is provided in the vicinity of the suction port 25 and detects the temperature of the suction airflow of the air conditioner 2 sucked from the suction port 25. The suction port temperature sensor 4 is formed of, for example, a thermistor.

制御部5は、空気調和機2の内部に設けられ、例えば運転室に設けられた操作部(図示せず)からの操作に基づいて、空気調和機2の運転(暖房運転や冷房運転等)を制御する。制御部5は、操作部(図示せず)で客室23の空気の温度が設定された場合には、吸い込み口温度センサ4で検出された空気調和機2の吸い込み気流の温度が操作部(図示せず)で設定された温度になるように、空気調和機2の運転を制御する(以下、操作部(図示せず)で設定された温度を「設定温度」という。)。   The control unit 5 is provided inside the air conditioner 2, for example, based on an operation from an operation unit (not shown) provided in the cab, the operation of the air conditioner 2 (heating operation, cooling operation, etc.). To control. When the temperature of the air in the passenger compartment 23 is set by the operation unit (not shown), the control unit 5 determines the temperature of the suction airflow of the air conditioner 2 detected by the suction port temperature sensor 4. The operation of the air conditioner 2 is controlled so that the temperature is set in (not shown) (hereinafter, the temperature set in the operation unit (not shown) is referred to as “set temperature”).

制御部5は、更に、空気調和機2の暖房運転の状態に応じて、横断流送風機3の送風動作を制御する。   The control unit 5 further controls the air blowing operation of the cross flow blower 3 according to the heating operation state of the air conditioner 2.

(車両用空調システムの動作)
次に、実施の形態1に係る車両用空調システムの動作について説明する。
制御部5は、空気調和機2の暖房運転を開始した際に、横断流送風機3の送風動作を開始させる。この時、制御部5は、車両21の幅方向に揺動しつつ送風を行うような過渡的な送風動作を横断流送風機3に行わせる。このような過渡的な送風動作により、客室23の空気の攪拌・混合が促進され、客室23の空気の温度を均一にすることができる。その後、制御部5は、空気調和機2の暖房運転を停止した際に、横断流送風機3の送風動作を停止する。なお、横断流送風機3の揺動速度が速い程、客室23の空気の攪拌・混合が促進される。そのため、例えば、横断流送風機3から送風される空気が客室23を30秒以内で往復するような揺動速度に設定されるとよい。揺動速度は、客室23の形態等に応じて設定される必要がある。また、揺動速度は、乗客が受ける不快感がどの程度かを考慮して設定される。
(Operation of vehicle air conditioning system)
Next, the operation of the vehicle air conditioning system according to Embodiment 1 will be described.
When the heating operation of the air conditioner 2 is started, the control unit 5 starts the blowing operation of the cross flow fan 3. At this time, the control unit 5 causes the cross flow blower 3 to perform a transient blowing operation that blows air while swinging in the width direction of the vehicle 21. By such a transient air blowing operation, stirring and mixing of the air in the cabin 23 is promoted, and the temperature of the air in the cabin 23 can be made uniform. Thereafter, when the heating operation of the air conditioner 2 is stopped, the control unit 5 stops the blowing operation of the cross flow fan 3. In addition, stirring and mixing of the air of the passenger room 23 are promoted, so that the rocking speed of the cross flow fan 3 is high. Therefore, for example, it is preferable to set the swing speed so that the air blown from the cross-flow blower 3 reciprocates the cabin 23 within 30 seconds. The rocking speed needs to be set according to the form of the cabin 23 and the like. The swing speed is set in consideration of the level of discomfort experienced by the passenger.

(車両用空調システムの作用)
次に、実施の形態1に係る車両用空調システムの作用について説明する。
まず、従来の車両用空調システムとして、横断流送風機3を有しない車両用空調システム(以下、「比較例1」という。)の作用について説明する。
空気調和機2の暖房運転を開始する前は、客室23の空気の温度は設定温度以下である。空気調和機2の暖房運転を開始した後は、吹き出し口26から暖房気流が吹き出されるため、客室23の空気の温度は上昇するが、暖房気流は、客室23の空気より密度が小さく、客室23の上方に溜まって客室23の下方まで到達しない。そのため、客室23の空気は、高さ方向に大きな温度分布を生じ、例えば座席28に座った乗客は寒さを感じることとなる。
(Operation of air conditioning system for vehicles)
Next, the operation of the vehicle air conditioning system according to Embodiment 1 will be described.
First, the operation of a vehicle air conditioning system (hereinafter referred to as “Comparative Example 1”) that does not have the cross-flow blower 3 will be described as a conventional vehicle air conditioning system.
Before the heating operation of the air conditioner 2 is started, the temperature of the air in the passenger room 23 is equal to or lower than the set temperature. After the heating operation of the air conditioner 2 is started, since the heating airflow is blown out from the outlet 26, the temperature of the air in the guest room 23 rises, but the heating airflow is less dense than the air in the guest room 23, It accumulates above 23 and does not reach below the guest room 23. Therefore, the air in the cabin 23 has a large temperature distribution in the height direction, and for example, a passenger sitting on the seat 28 feels cold.

図2は、比較例1に係る車両用空調システムの空気調和機が暖房運転を開始した後における客室の空気の温度分布をシミュレーションした結果を示す図である。なお、図2は、空気調和機2の暖房運転を開始した後1分後における温度分布をシミュレーションした結果である。図2に示すように、客室23の空気には、大きな温度分布が生じる。温度分布は、高さ方向に層状となり、特に、乗客が座る客室23の下方で大きい温度差が生じる。   FIG. 2 is a diagram illustrating a result of simulating the temperature distribution of the air in the cabin after the air conditioner of the vehicle air conditioning system according to Comparative Example 1 starts the heating operation. In addition, FIG. 2 is the result of simulating the temperature distribution 1 minute after starting the heating operation of the air conditioner 2. As shown in FIG. 2, a large temperature distribution is generated in the air in the cabin 23. The temperature distribution is stratified in the height direction, and a large temperature difference occurs particularly below the passenger cabin 23 where passengers sit.

次に、実施の形態1に係る車両用空調システムの作用について説明する。図3は、実施の形態1に係る車両用空調システムの空気調和機が暖房運転を開始した後における客室の空気の温度分布をシミュレーションした結果を示す図である。なお、図3は、図2と同様に、空気調和機2の暖房運転を開始した後1分後における温度分布をシミュレーションした結果である。図3に示すように、実施の形態1に係る車両用空調システムでは、客室23の空気の温度分布が低減される。   Next, the operation of the vehicle air conditioning system according to Embodiment 1 will be described. FIG. 3 is a diagram illustrating a result of simulating the temperature distribution of the air in the cabin after the air conditioner of the vehicle air conditioning system according to Embodiment 1 starts the heating operation. In addition, FIG. 3 is the result of having simulated the temperature distribution 1 minute after starting the heating operation of the air conditioner 2 similarly to FIG. As shown in FIG. 3, in the vehicle air conditioning system according to Embodiment 1, the temperature distribution of the air in the passenger compartment 23 is reduced.

図4は、比較例1に係る車両用空調システムと実施の形態1に係る車両用空調システムの客室の空気の温度の時間変化をシミュレーションした結果を示す図である。なお、図4は、比較例1に係る車両用空調システムと実施の形態1に係る車両用空調システムにおける、床面から0mと0.5mの高さでの空気の温度の時間変化について示している。図4に示すように、比較例1に係る車両用空調システムに対して、実施の形態1に係る車両用空調システムでは、客室23の空気の温度を均一に且つ速く上昇できることが分かる。   FIG. 4 is a diagram illustrating a result of simulating time-dependent changes in the temperature of air in the cabin of the vehicle air conditioning system according to Comparative Example 1 and the vehicle air conditioning system according to Embodiment 1. FIG. 4 shows the time change of the air temperature at the height of 0 m and 0.5 m from the floor surface in the vehicle air conditioning system according to Comparative Example 1 and the vehicle air conditioning system according to Embodiment 1. Yes. As shown in FIG. 4, it can be seen that the temperature of the air in the cabin 23 can be increased uniformly and quickly in the vehicle air conditioning system according to the first embodiment compared to the vehicle air conditioning system according to Comparative Example 1.

図5は、実施の形態1に係る車両用空調システムの横断流送風機が揺動動作を行わない場合の気流を示す図である。横断流送風機3が、一方向を向くように固定された状態で送風を行う場合には、例えば、図5に示すように、乗客61によって気流が遮られてしまい、座席28に座っている乗客62の周辺の空気を攪拌・混合することができないため、座席28に座っている乗客62の周辺に低温領域が生じてしまう。一方、横断流送風機3が、車両21の幅方向に揺動しつつ送風を行う場合には、乗客が多数いるような場合でも、客室23の空気の温度分布、特に車両21の幅方向の温度分布を均一にすることができる。   FIG. 5 is a diagram illustrating an air flow when the cross flow blower of the vehicle air conditioning system according to Embodiment 1 does not perform the swinging operation. When the cross flow blower 3 blows air in a state where it is fixed to face in one direction, for example, as shown in FIG. 5, the passenger 61 is sitting on the seat 28 because the air flow is blocked by the passenger 61. Since the air around 62 cannot be stirred and mixed, a low temperature region is generated around the passenger 62 sitting on the seat 28. On the other hand, when the cross flow blower 3 blows air while swinging in the width direction of the vehicle 21, the temperature distribution of the air in the cabin 23, particularly the temperature in the width direction of the vehicle 21, even when there are many passengers. The distribution can be made uniform.

以上のように、実施の形態1に係る車両用空調システムでは、空気調和機2が暖房運転を開始した際に、横断流送風機3が揺動しつつ送風を行う動作を開始して、客室23の空気を攪拌・混合するため、客室23の空気の温度を短時間で均一にし、且つ、短時間で上昇させることが可能となる。
そのため、乗客の快適性を向上することができる。また、客室23の壁面等に新たな風路が設けられなくてもよいため、乗客の快適性を簡易な構造で向上することができる、という顕著な効果が奏される。
As described above, in the vehicle air-conditioning system according to Embodiment 1, when the air conditioner 2 starts the heating operation, the cross-flow fan 3 starts the operation of blowing air while swinging, and the cabin 23 Therefore, the temperature of the air in the cabin 23 can be made uniform in a short time and can be increased in a short time.
Therefore, passenger comfort can be improved. Moreover, since it is not necessary to provide a new air path on the wall surface of the passenger room 23 or the like, there is a remarkable effect that passenger comfort can be improved with a simple structure.

また、横断流送風機3が、車両21の客室23の天井24の裏側で且つ車両21の幅方向の略中央に設けられており、客室23の全体に効率よく空気を送ることができる。そのため、客室23の空気の攪拌・混合がより促進され、客室23の空気の温度をより短時間で均一にし、且つ、より短時間で上昇させることが可能となる。   Further, the cross-flow blower 3 is provided on the back side of the ceiling 24 of the passenger cabin 23 of the vehicle 21 and in the approximate center in the width direction of the vehicle 21, so that air can be efficiently sent to the entire passenger cabin 23. Therefore, stirring / mixing of the air in the passenger compartment 23 is further promoted, and the temperature of the air in the passenger compartment 23 can be made uniform in a shorter time and raised in a shorter time.

なお、1つの空気調和機2に対して1つの横断流送風機3が設けられる場合について説明しているが、1つの空気調和機2に対して車両21の長手方向に横断流送風機3が複数並べて設けられ、1つの空気調和機2が暖房運転を行う際に、複数の横断流送風機3が送風動作を行ってもよい。また、車両21の長手方向に空気調和機2が複数並べて設けられ、複数の空気調和機2のそれぞれに対して1つ又は複数の横断流送風機3が設けられてもよい。   In addition, although the case where one cross flow fan 3 is provided for one air conditioner 2 is described, a plurality of cross flow fans 3 are arranged in the longitudinal direction of the vehicle 21 with respect to one air conditioner 2. A plurality of cross-flow fans 3 may perform an air blowing operation when one air conditioner 2 performs a heating operation. A plurality of air conditioners 2 may be provided side by side in the longitudinal direction of the vehicle 21, and one or a plurality of cross flow fans 3 may be provided for each of the plurality of air conditioners 2.

また、空気調和機2が暖房運転を行う際に、横断流送風機3が常に送風動作を行う場合について説明している。しかし、横断流送風機3が揺動しつつ送風を行うため、気流が乗客のそれぞれに直接当たる時間は短いものの、横断流送風機3が常に送風動作を行う場合には、乗客が気流を感じてしまい、快適性が損なわれる可能性がある。また、時間の経過に伴って、客室23の空気の温度分布は均一になるため、横断流送風機3の送風動作によって客室23の空気が攪拌・混合されなくても乗客の快適性が損なわれない可能性がある。そのため、空気調和機2の暖房運転を行う際に、横断流送風機3が常に送風動作を行わなくてもよい。   Moreover, when the air conditioner 2 performs heating operation, the case where the cross flow fan 3 always performs a blowing operation is described. However, since the crossflow blower 3 blows while swinging, the time for the airflow to directly hit each passenger is short, but when the crossflow blower 3 always performs the blowing operation, the passenger feels the airflow. The comfort may be impaired. In addition, since the temperature distribution of the air in the passenger compartment 23 becomes uniform over time, passenger comfort is not impaired even if the air in the passenger compartment 23 is not agitated and mixed by the air blowing operation of the cross flow fan 3. there is a possibility. Therefore, when performing the heating operation of the air conditioner 2, the cross flow blower 3 does not always have to perform the blowing operation.

図6及び図7は、実施の形態1に係る車両用空調システムの制御の変形例を示す図である。制御部5は、例えば、図6に示すように、空気調和機2の暖房運転を開始した後、第1の所定の時間(ΔtON−1)だけ横断流送風機3の送風動作を行い、第1の所定の時間(ΔtON−1)が経過した後に横断流送風機3の送風動作を停止してもよい(なお、第1の所定の時間(ΔtON−1)は、本発明における「第1所定時間」に相当する。)。また、制御部5は、例えば、図7に示すように、横断流送風機3の送風動作を停止して第2の所定の時間(ΔtOFF−2)が経過した後に、横断流送風機3の送風動作を再び開始させることを繰り返してもよい。なお、第1の所定の時間(ΔtON−1)は、1〜3分の範囲とするのがよい。第1の所定の時間(ΔtON−1)は、客室23の形態等に応じて設定される必要がある。また、第1の所定の時間(ΔtON−1)は、乗客が受ける不快感がどの程度かを考慮して設定される。また、第2の所定の時間(ΔtOFF−2)は、客室23の熱漏洩量等の熱的な負荷に応じて設定される必要があり、横断流送風機3の送風動作を停止した後の客室23の空気の温度分布の経時変化を実測する等によって設定される。 6 and 7 are diagrams showing a modification of the control of the vehicle air conditioning system according to Embodiment 1. FIG. For example, as illustrated in FIG. 6, the control unit 5 performs the air blowing operation of the cross flow fan 3 for the first predetermined time (Δt ON-1 ) after starting the heating operation of the air conditioner 2, 1 may be stopped after a predetermined time (Δt ON-1 ) has elapsed (note that the first predetermined time (Δt ON-1 ) Corresponds to "1 predetermined time"). Further, for example, as illustrated in FIG. 7, the control unit 5 stops the air blowing operation of the cross flow fan 3, and after the second predetermined time (Δt OFF−2 ) has elapsed, the air flow of the cross flow fan 3. You may repeat starting operation | movement again. The first predetermined time (Δt ON-1 ) is preferably in the range of 1 to 3 minutes. The first predetermined time (Δt ON-1 ) needs to be set according to the form of the guest room 23 and the like. The first predetermined time (Δt ON-1 ) is set in consideration of the degree of discomfort experienced by the passenger. In addition, the second predetermined time (Δt OFF−2 ) needs to be set according to a thermal load such as the heat leakage amount of the cabin 23, and after the air blowing operation of the cross flow blower 3 is stopped. It is set by, for example, actually measuring the change over time in the temperature distribution of the air in the guest room 23.

また、横断流送風機3の送風動作が、空気調和機2の暖房動作の開始と同時に開始するものとして説明しているが、例えば、空気調和機2の暖房動作の開始と横断流送風機3の送風動作の開始とに時間差があってもよい。空気調和機2の暖房動作の開始と横断流送風機3の送風動作の開始とが同時である場合には、客室23の空気の温度をより短時間で均一にし、且つ、より短時間で上昇させることができ、乗客の快適性をより向上することが可能となる。また、例えば、横断流送風機3が、空気調和機2の暖房動作が停止している状態では、遅い揺動速度又は少ない風量又は少ない揺動量で送風動作を行い、空気調和機2の暖房動作が行われている状態では、速い揺動速度又は多い風量又は多い揺動量で送風動作を行うように制御されてもよい。また、そのような場合には、横断流送風機3の揺動速度と風量と揺動量の全て又はいずれか2つが同時に制御されてもよい。   Moreover, although the ventilation operation | movement of the crossflow fan 3 is demonstrated as what starts simultaneously with the start of the heating operation of the air conditioner 2, for example, the start of the heating operation of the air conditioner 2 and the ventilation of the crossflow fan 3 There may be a time difference from the start of the operation. When the start of the heating operation of the air conditioner 2 and the start of the blowing operation of the cross flow blower 3 are simultaneous, the temperature of the air in the cabin 23 is made uniform in a shorter time and raised in a shorter time. This makes it possible to improve passenger comfort. In addition, for example, when the cross-flow blower 3 is in a state where the heating operation of the air conditioner 2 is stopped, the blowing operation is performed at a slow swing speed, a small air volume, or a small swing amount, and the heating operation of the air conditioner 2 is performed. In the state where it is performed, it may be controlled to perform the air blowing operation at a high rocking speed or a large air volume or a large rocking amount. In such a case, all or any two of the swing speed, the air volume, and the swing amount of the cross flow fan 3 may be controlled simultaneously.

(車両用空調システムの動作)
次に、実施の形態2に係る車両用空調システムの動作について説明する。
横断流送風機3は、図7に示すように、空気調和機2が暖房動作を開始した後、第1の所定の時間(ΔtON−1)だけ送風動作を行い、第2の所定の時間(ΔtOFF−2)だけ送風動作を停止することを、周期的に繰り返している。
(Operation of vehicle air conditioning system)

It is a figure which shows control in the case. As shown in FIG. 9 and FIG. 10, the control unit 7 starts the heating operation of the air conditioner 2 and then stops the air blowing operation of the cross flow blower 3. When it is recognized that the door 29 is opened based on the opening / closing signal, the blowing operation of the cross flow fan 3 is maintained in a stopped state, and it is recognized that the door 29 is closed based on the door opening / closing signal from the door opening / closing control device 30. Then, the air blowing operation of the cross flow blower 3 is started. After starting the air blowing operation of the cross flow blower 3, the control unit 7 performs the air blowing operation of the cross flow blower 3 for a third predetermined time (Δt ON-3 ), and performs a third predetermined time (Δt ON− 3 )), the cross-flow blower 3 stops the air blowing operation (the third predetermined time (Δt ON-3 ) corresponds to the “second predetermined time” in the present invention).

図11は、実施の形態2に係る車両用空調システムの横断流送風機が送風動作を行っている時にドアが開き、第1の所定の時間(ΔtON−1)を経過する前にドアが閉まる場合の制御を示す図である。図12は、実施の形態2に係る車両用空調システムの横断流送風機が送風動作を行っている時にドアが開き、第1の所定の時間(ΔtON−1)を経過した後にドアが閉まる場合の制御を示す図である。図11及び図12に示すように、制御部7は、空気調和機2の暖房運転を開始した後、横断流送風機3の送風動作を行っているときに、ドア開閉制御装置30からのドア開閉信号に基づいてドア29が開いたことを認識すると、横断流送風機3の送風動作を停止し、ドア開閉制御装置30からのドア開閉信号に基づいてドア29が閉まったことを認識すると、横断流送風機3の送風動作を開始する。制御部7は、横断流送風機3の送風動作を開始した後、第3の所定の時間(ΔtON−3)だけ横断流送風機3の送風動作を行い、第3の所定の時間(ΔtON−3)が経過した後に横断流送風機3の送風動作を停止する。 FIG. 11 shows that the door is opened when the cross flow blower of the vehicle air conditioning system according to the second embodiment performs the blowing operation, and the door is closed before the first predetermined time (Δt ON-1 ) elapses. It is a figure which shows control in the case. FIG. 12 shows a case where the door is opened when the cross flow blower of the vehicle air conditioning system according to the second embodiment performs a blowing operation, and the door is closed after the first predetermined time (Δt ON-1 ) has elapsed. It is a figure which shows control of. As shown in FIGS. 11 and 12, the controller 7 opens and closes the door from the door opening / closing control device 30 when the air flow of the cross flow fan 3 is being performed after the heating operation of the air conditioner 2 is started. When it is recognized that the door 29 is opened based on the signal, the blowing operation of the cross flow fan 3 is stopped, and when it is recognized that the door 29 is closed based on the door opening / closing signal from the door opening / closing control device 30, The blowing operation of the blower 3 is started.

(車両用空調システムの作用)
次に、実施の形態2に係る車両用空調システムの作用について説明する。
乗客が乗り降りする際にドア29が開閉動作を行うと、客室23に冷たい外気が流入するため、客室23の空気の温度は設定温度以下になる。吹き出し口26からは暖房気流が吹き出されているため、ドア29を閉じた後に客室23の空気の温度は上昇するが、暖房気流は、客室23の空気の温度より密度が小さく、客室23の上方に溜まって客室23の下方まで到達しない。そのため、客室23の空気は、高さ方向に大きな温度分布を生じ、例えば座席28に座った乗客は寒さを感じることとなる。
(Operation of air conditioning system for vehicles)
Next, the operation of the vehicle air conditioning system according to Embodiment 2 will be described.
If the door 29 opens and closes when a passenger gets on and off, cold outside air flows into the passenger compartment 23, so that the temperature of the air in the passenger compartment 23 is equal to or lower than the set temperature. Since the heating airflow is blown out from the outlet 26, the temperature of the air in the guest room 23 rises after the door 29 is closed. And does not reach the lower part of the guest room 23. Therefore, the air in the cabin 23 has a large temperature distribution in the height direction, and for example, a passenger sitting on the seat 28 feels cold.

実施の形態2に係る車両用空調システムでは、ドア29の開閉動作によって客室23の空気に温度分布が生じた場合に、横断流送風機3が送風動作を開始し、客室23の空気を攪拌・混合するため、客室23の空気の温度を短時間で均一にし、且つ、短時間で上昇させることが可能となる。
そのため、乗客の快適性を向上することができる。また、客室23の壁面等に新たな風路が設けられなくてもよいため、乗客の快適性を簡易な構造で向上することができる、という顕著な効果が奏される。
In the vehicular air conditioning system according to the second embodiment, when the temperature distribution is generated in the air in the cabin 23 due to the opening / closing operation of the door 29, the cross flow blower 3 starts the blowing operation, and the air in the cabin 23 is stirred and mixed. Therefore, the temperature of the air in the cabin 23 can be made uniform in a short time and can be raised in a short time.
Therefore, passenger comfort can be improved. Moreover, since it is not necessary to provide a new air path on the wall surface of the passenger room 23 or the like, there is a remarkable effect that passenger comfort can be improved with a simple structure.

なお、1つの空気調和機2に対して1つの横断流送風機3が設けられる場合について説明しているが、1つの空気調和機2に対して車両21の長手方向に横断流送風機3が複数並べて設けられ、1つの空気調和機2が暖房運転を行う際に、複数の横断流送風機3が送風動作を行ってもよい。また、車両21の長手方向に空気調和機2が複数並べて設けられ、複数の空気調和機2のそれぞれに対して1つ又は複数の横断流送風機3が設けられてもよい。   In addition, although the case where one cross flow fan 3 is provided for one air conditioner 2 is described, a plurality of cross flow fans 3 are arranged in the longitudinal direction of the vehicle 21 with respect to one air conditioner 2. A plurality of cross-flow fans 3 may perform an air blowing operation when one air conditioner 2 performs a heating operation. A plurality of air conditioners 2 may be provided side by side in the longitudinal direction of the vehicle 21, and one or a plurality of cross flow fans 3 may be provided for each of the plurality of air conditioners 2.

また、制御部7は、ドア29が開いている時に、横断流送風機3の送風動作を停止しているが、ドア29が開いている時に、横断流送風機3の送風動作を行ってもよい。図13は、実施の形態2に係る車両用空調システムの横断流送風機が送風動作を停止している時にドアが開き、第2の所定の時間(ΔtOFF−2)を経過する前にドアが閉まる場合の制御の変形例を示す図である。図14は、実施の形態2に係る車両用空調システムの横断流送風機が送風動作を停止している時にドアが開き、第2の所定の時間(ΔtOFF−2)を経過した後にドアが閉まる場合の制御の変形例を示す図である。図15は、実施の形態2に係る車両用空調システムの横断流送風機が送風動作を行っている時にドアが開き、第1の所定の時間(ΔtON−1)を経過する前にドアが閉まる場合の制御の変形例を示す図である。図16は、実施の形態2に係る車両用空調システムの横断流送風機が送風動作を行っている時にドアが開き、第1の所定の時間(ΔtON−1)を経過した後にドアが閉まる場合の制御の変形例を示す図である。図13乃至図16に示すように、制御部7は、ドア開閉制御装置30からのドア開閉信号に基づいてドア29が開いたことを認識すると、横断流送風機3の送風動作を開始又は継続し、ドア開閉制御装置30からのドア開閉信号に基づいてドア29が閉まったことを認識してから第3の所定の時間(ΔtON−3)だけ横断流送風機3の送風動作を行ってもよい。なお、図9乃至図16では、ドア29が開いてからドア29が閉まるまでの時間が、第1の所定の時間(ΔtON−1)や第2の所定の時間(ΔtOFF−2)より短い場合を示しているが、第1の所定の時間(ΔtON−1)や第2の所定の時間(ΔtOFF−2)より長い場合でも同様の制御を行えばよい。 Further, the control unit 7 stops the blowing operation of the cross flow fan 3 when the door 29 is open, but may perform the blowing operation of the cross flow fan 3 when the door 29 is open. FIG. 13 shows that the door is opened when the cross flow blower of the vehicle air conditioning system according to the second embodiment stops the blowing operation, and the door is opened before the second predetermined time (Δt OFF−2 ) has passed. It is a figure which shows the modification of control in the case of closing. FIG. 14 shows that the door is opened when the cross flow blower of the vehicle air conditioning system according to the second embodiment stops the blowing operation, and the door is closed after the second predetermined time (Δt OFF−2 ) has passed. It is a figure which shows the modification of the control in a case. FIG. 15 shows that the door is opened when the cross flow blower of the vehicle air conditioning system according to the second embodiment performs a blowing operation, and the door is closed before the first predetermined time (Δt ON-1 ) elapses. It is a figure which shows the modification of the control in a case. FIG. 16 shows a case where the door is opened when the cross flow blower of the vehicle air conditioning system according to the second embodiment performs a blowing operation, and the door is closed after the first predetermined time (Δt ON-1 ) has elapsed. It is a figure which shows the modification of this control. As shown in FIGS. 13 to 16, when the control unit 7 recognizes that the door 29 is opened based on the door opening / closing signal from the door opening / closing control device 30, the control unit 7 starts or continues the blowing operation of the cross flow fan 3. The cross flow blower 3 may perform the air blowing operation for the third predetermined time (Δt ON-3 ) after recognizing that the door 29 is closed based on the door open / close signal from the door open / close control device 30. . 9 to 16, the time from when the door 29 is opened until the door 29 is closed is based on the first predetermined time (Δt ON-1 ) or the second predetermined time (Δt OFF-2 ). Although a short case is shown, similar control may be performed even when the time is longer than the first predetermined time (Δt ON-1 ) or the second predetermined time (Δt OFF-2 ).

また、横断流送風機3が、図7に示すように、空気調和機2が暖房動作を開始した後、第1の所定の時間(ΔtON−1)だけ送風動作を行い、第2の所定の時間(ΔtOFF−2)だけ送風動作を停止することを、周期的に繰り返している場合について説明しているが、図6に示すように、空気調和機2が暖房動作を開始した後、第1の所定の時間(ΔtON−1)だけ送風動作を行ってもよく、また、常に送風動作を行ってもよい。また、空気調和機2が暖房動作を行っているだけの状態では横断流送風機3が送風動作を行わず、空気調和機2が暖房動作を行っている状態でドア29の開閉動作が行われた時だけ横断流送風機3が送風動作を行ってもよい。横断流送風機3の送風動作が、空気調和機2の暖房動作の開始と同時に開始し、ドア29の開閉動作が行われた時にも横断流送風機3が送風動作を行う場合には、客室23の空気の温度をより短時間で均一にし、且つ、より短時間で上昇させることができ、乗客の快適性をより向上することが可能となる。 In addition, as shown in FIG. 7, after the air conditioner 2 starts the heating operation, the cross flow blower 3 performs the blowing operation for the first predetermined time (Δt ON−1 ), and the second predetermined flow The case where the air blowing operation is stopped periodically for the time (Δt OFF−2 ) is described. As shown in FIG. 6, after the air conditioner 2 starts the heating operation, The air blowing operation may be performed for a predetermined time of 1 (Δt ON-1 ), or the air blowing operation may always be performed. Further, when the air conditioner 2 is only performing the heating operation, the cross flow blower 3 does not perform the blowing operation, and the door 29 is opened and closed while the air conditioner 2 is performing the heating operation. Only when the cross flow blower 3 may perform the blowing operation. When the cross-flow blower 3 starts the blowing operation simultaneously with the start of the heating operation of the air conditioner 2 and the cross-flow blower 3 performs the blowing operation even when the door 29 is opened and closed, The temperature of the air can be made uniform in a shorter time and can be raised in a shorter time, and passenger comfort can be further improved.

また、横断流送風機3が、ドア29が閉められた時に、送風動作を開始又は継続し、ドア29が閉められてから第3の所定の時間(ΔtON−3)が経過した時に、送風動作を停止しているが、横断流送風機3が、ドア29が閉められた時に、速い揺動速度又は多い風量又は多い揺動量の送風動作に制御され、ドア29が閉められてから第3の所定の時間(ΔtON−3)が経過した時に、遅い揺動速度又は少ない風量又は少ない揺動量の送風動作に制御されてもよい。また、そのような場合には、横断流送風機3の揺動速度と風量と揺動量の全て又はいずれか2つが同時に制御されてもよい。 The cross flow blower 3 starts or continues the blowing operation when the door 29 is closed, and the blowing operation is performed when a third predetermined time (Δt ON-3 ) has elapsed since the door 29 was closed. However, when the door 29 is closed, the cross-flow blower 3 is controlled to a high swing speed or a large air flow or a large air blow operation, and after the door 29 is closed, the third predetermined When the time (Δt ON-3 ) elapses, the air flow may be controlled to be a slow swing speed, a small air volume, or a small air volume. In such a case, all or any two of the swing speed, the air volume, and the swing amount of the cross flow fan 3 may be controlled simultaneously.

An arrow 44B indicates a state where the cross flow blower 3 swings and blows air to the right region of the cabin 23. The blown airflow of the cross-flow fan 3 in FIG. The air outlet 27 is located at the approximate center in the width direction of the vehicle 21.

吸い込み口温度センサ4は、吸い込み口25の近傍に設けられ、吸い込み口25から吸い込まれる空気調和機2の吸い込み気流の温度を検出する。吸い込み口温度センサ4は、例えばサーミスタ等からなる。   The suction port temperature sensor 4 is provided in the vicinity of the suction port 25 and detects the temperature of the suction airflow of the air conditioner 2 sucked from the suction port 25. The suction port temperature sensor 4 is formed of, for example, a thermistor.

The solar radiation sensors 9A and 9B are composed of, for example, a radiant heat sensor or an infrared sensor.

制御部10は、空気調和機2の内部に設けられ、例えば運転室に設けられた操作部(図示せず)からの操作に基づいて、空気調和機2の運転(暖房運転や冷房運転等)を制御する。制御部10は、操作部(図示せず)で設定温度が設定された場合には、吸い込み口温度センサ4で検出された空気調和機2の吸い込み気流の温度が設定温度になるように、空気調和機2の運転を制御する。   The control unit 10 is provided inside the air conditioner 2, for example, based on an operation from an operation unit (not shown) provided in the cab, the operation of the air conditioner 2 (heating operation, cooling operation, etc.). To control. When the set temperature is set by the operation unit (not shown), the control unit 10 controls the air so that the temperature of the suction airflow of the air conditioner 2 detected by the suction port temperature sensor 4 becomes the set temperature.

The control unit 10 further controls the blowing operation of the cross flow blower 3 according to the solar radiation state of the passenger room 23.

(車両用空調システムの動作)
次に、実施の形態3に係る車両用空調システムの動作について説明する。
制御部10は、空気調和機2が暖房動作を開始した際に、横断流送風機3の送風動作を開始する。横断流送風機3は、車両21の幅方向に揺動しつつ送風を行うような過渡的な送風動作を行う。制御部10は、横断流送風機3の送風動作を開始する際又は開始する前に、日射センサ9A、9Bの出力値の差から車両21の各側面における日射量の差を求め、客室23の日射量が多い側に送風する際の横断流送風機3の揺動速度は速く、客室23の日射量が少ない側に送風する際の横断流送風機3の揺動速度は遅くなるように、横断流送風機3の送風動作を制御する。その後、制御部10は、空気調和機2の暖房運転を停止した際に、横断流送風機3の送風動作を停止する。
(Operation of vehicle air conditioning system)
Next, the operation of the vehicle air conditioning system according to Embodiment 3 will be described.
The control unit 10 starts the air blowing operation of the cross flow fan 3 when the air conditioner 2 starts the heating operation. The cross flow blower 3 performs a transient blowing operation such as blowing while swinging in the width direction of the vehicle 21. The control unit 10 obtains the difference in the amount of solar radiation on each side surface of the vehicle 21 from the difference in the output values of the solar radiation sensors 9A and 9B when starting the air blowing operation of the cross flow blower 3 or before starting the air blowing operation. The cross flow blower 3 has a fast swinging speed when it is blown to the side with a large amount, and the cross flow blower 3 has a slow swinging speed when it is blown to the side of the cabin 23 where the amount of solar radiation is low. 3 is controlled. Thereafter, when the heating operation of the air conditioner 2 is stopped, the control unit 10 stops the blowing operation of the cross flow fan 3.

例えば、図17における日射方向を示す矢印45のように、車両21の左側面に日光が多く当たっている場合には、日射センサ9Aの出力値の方が日射センサ9Bの出力値よりも大きくなる。制御部10は、日射センサ9A、9Bの出力値の差から、車両21の左側面に日光が多く当たっていることを認識する。そして、制御部10は、客室23の左側の領域において横断流送風機の動きを示す矢印43Aの領域を横断流送風機3が揺動する際は、揺動速度が速くなり、客室23の右側の領域において横断流送風機の動きを示す矢印43Bの領域を横断流送風機3が揺動する際は、揺動速度が遅くなるように、横断流送風機3を動作させる。なお、左右における揺動速度の比は、予め固定値が設定されていてもよく、また、車両21の各側面における日射量の差の大きさに応じて連続的に又は階段状に大きくなるように設定されてもよい。揺動速度の比の具体的な値は、乗客の快適性を損なわない比を実測する等によって設定されるとよい。   For example, as shown by the arrow 45 indicating the solar radiation direction in FIG. 17, when a lot of sunlight hits the left side surface of the vehicle 21, the output value of the solar sensor 9 </ b> A is larger than the output value of the solar sensor 9 </ b> B. . The control unit 10 recognizes that a large amount of sunlight has hit the left side surface of the vehicle 21 from the difference between the output values of the solar radiation sensors 9A and 9B. When the cross flow fan 3 swings in the area of the arrow 43A indicating the movement of the cross flow fan in the left area of the passenger room 23, the control unit 10 increases the swing speed, and the right area of the guest room 23 When the cross flow blower 3 swings in the region of the arrow 43B indicating the movement of the cross flow blower in FIG. 2, the cross flow blower 3 is operated so that the swing speed becomes slow. It should be noted that the ratio of the rocking speeds on the left and right sides may be set in advance, and may increase continuously or stepwise depending on the difference in the amount of solar radiation on each side of the vehicle 21. May be set. A specific value of the ratio of the swing speeds may be set by actually measuring a ratio that does not impair passenger comfort.

(車両用空調システムの作用)
次に、実施の形態3に係る車両用空調システムの作用について説明する。
実施の形態1及び実施の形態2に係る車両用空調システムは、主に暖房運転時に生じる客室23の空気の車両21の高さ方向における温度分布を低減するものであるが、実施の形態3に係る車両用空調システムは、暖房運転時に生じる客室23の空気の車両21の高さ方向における温度分布に加えて、日射によって生じる客室23の空気の車両21の幅方向における温度分布を低減するものである。
(Operation of air conditioning system for vehicles)
Next, the operation of the vehicle air conditioning system according to Embodiment 3 will be described.
The vehicle air conditioning system according to Embodiment 1 and Embodiment 2 is intended to reduce the temperature distribution in the height direction of the vehicle 21 of the air in the passenger room 23 that occurs mainly during heating operation. The vehicle air-conditioning system reduces the temperature distribution of the air in the cabin 23 caused by solar radiation in the width direction of the vehicle 21 in addition to the temperature distribution of the air in the cabin 23 that occurs during the heating operation in the height direction of the vehicle 21. is there.

空気調和機2の暖房運転を開始する前は、客室23の空気の温度は設定温度以下である。空気調和機2の暖房運転を開始した後は、吹き出し口26から暖房気流が吹き出されるため、客室23の空気の温度は上昇するが、暖房気流は、客室23の空気より密度が小さく、客室23の上方に溜まって客室23の下方まで到達しない。そのため、客室23の空気は、高さ方向に大きな温度分布を生じ、例えば座席28に座った乗客は寒さを感じることとなる。   Before the heating operation of the air conditioner 2 is started, the temperature of the air in the passenger room 23 is equal to or lower than the set temperature. After the heating operation of the air conditioner 2 is started, since the heating airflow is blown out from the outlet 26, the temperature of the air in the guest room 23 rises, but the heating airflow is less dense than the air in the guest room 23, It accumulates above 23 and does not reach below the guest room 23. Therefore, the air in the cabin 23 has a large temperature distribution in the height direction, and for example, a passenger sitting on the seat 28 feels cold.

また、客室23の空気の温度分布は、車両21に当たる日光によっても生じる。例えば、図17のように、日光が車両21の左側から当たると、客室23の左側の空気の温度が客室23の右側の空気の温度より高くなる。客室23の空気は、車両21の高さ方向にも温度分布があるため、客室23の右下の座席28の近傍の空気が最も低い温度となる。   Further, the temperature distribution of the air in the passenger compartment 23 is also generated by sunlight hitting the vehicle 21. For example, as shown in FIG. 17, when sunlight hits the left side of the vehicle 21, the temperature of the air on the left side of the cabin 23 becomes higher than the temperature of the air on the right side of the cabin 23. Since the air in the passenger compartment 23 has a temperature distribution in the height direction of the vehicle 21, the air in the vicinity of the lower right seat 28 in the passenger compartment 23 has the lowest temperature.

実施の形態3に係る車両用空調システムでは、制御部10が、客室23の日射量が多い側に送風する際の横断流送風機3の揺動速度は速く、客室23の日射量が少ない側に送風する際の横断流送風機3の揺動速度は遅くなるように、横断流送風機3の送風動作を制御するため、客室23の日射量が少ない側に供給される暖房気流の割合が客室23の日射量が多い側に供給される暖房気流の割合より多くなり、客室23の日射量が少ない側の空気の温度が、客室23の日射量が多い側の空気の温度より上昇することとなる。そのため、客室23の空気の車両21の高さ方向における温度分布に加えて、客室23の空気の車両21の幅方向における温度分布を均一にできる。   In the vehicle air-conditioning system according to Embodiment 3, the swinging speed of the cross flow blower 3 when the control unit 10 blows air toward the side of the cabin 23 where the amount of solar radiation is large is fast, and the side of the cabin 23 where the amount of solar radiation is small. In order to control the blowing operation of the cross flow blower 3 so that the swing speed of the cross flow blower 3 at the time of blowing is slow, the ratio of the heating air flow supplied to the side of the cabin 23 where the amount of solar radiation is small is The ratio of the heating airflow supplied to the side with the larger amount of solar radiation is higher, and the temperature of the air on the side with the smaller amount of solar radiation in the guest room 23 is higher than the temperature of the air on the side with the larger amount of solar radiation in the guest room 23. Therefore, in addition to the temperature distribution of the air in the cabin 23 in the height direction of the vehicle 21, the temperature distribution of the air in the cabin 23 in the width direction of the vehicle 21 can be made uniform.

以上のように、実施の形態3に係る車両用空調システムでは、客室23の空気の車両21の高さ方向における温度分布に加えて、客室23の空気の車両21の幅方向における温度分布を均一にできるため、乗客の快適性をより向上することができる。また、客室23の壁面等に新たな風路が設けられなくてもよいため、乗客の快適性を簡易な構造で向上することができる、という顕著な効果が奏される。   As described above, in the vehicle air conditioning system according to Embodiment 3, in addition to the temperature distribution of the air in the passenger compartment 23 in the height direction of the vehicle 21, the temperature distribution of the air in the passenger compartment 23 in the width direction of the vehicle 21 is uniform. Therefore, passenger comfort can be further improved. Moreover, since it is not necessary to provide a new air path on the wall surface of the passenger room 23 or the like, there is a remarkable effect that passenger comfort can be improved with a simple structure.

なお、1つの空気調和機2に対して1つの横断流送風機3が設けられる場合について説明しているが、1つの空気調和機2に対して車両21の長手方向に横断流送風機3が複数並べて設けられ、1つの空気調和機2が暖房運転を行う際に、複数の横断流送風機3が送風動作を行ってもよい。また、車両21の長手方向に空気調和機2が複数並べて設けられ、複数の空気調和機2のそれぞれに対して1つ又は複数の横断流送風機3が設けられてもよい。   In addition, although the case where one cross flow fan 3 is provided for one air conditioner 2 is described, a plurality of cross flow fans 3 are arranged in the longitudinal direction of the vehicle 21 with respect to one air conditioner 2. A plurality of cross-flow fans 3 may perform an air blowing operation when one air conditioner 2 performs a heating operation. A plurality of air conditioners 2 may be provided side by side in the longitudinal direction of the vehicle 21, and one or a plurality of cross flow fans 3 may be provided for each of the plurality of air conditioners 2.

また、制御部10が、客室23の日射量が多い側に送風する際の横断流送風機3の揺動速度は速く、客室23の日射量が少ない側に送風する際の横断流送風機3の揺動速度は遅くなるように、横断流送風機3の送風動作を制御する場合について説明しているが、制御部10が、横断流送風機3の揺動速度は一定とし、客室23の日射量が多い側に送風する際の横断流送風機3の風量は少なく、客室23の日射量が少ない側に送風する際の横断流送風機3の風量は多くなるように、横断流送風機3の送風動作を制御してもよい。   In addition, the swinging speed of the cross flow fan 3 when the control unit 10 blows air toward the side of the cabin 23 where the amount of solar radiation is large is fast, and the swing of the cross flow fan 3 when air is blown toward the side of the cabin 23 where the amount of solar radiation is small. Although the case where the air blowing operation of the cross flow fan 3 is controlled so that the moving speed becomes slow has been described, the control unit 10 assumes that the swing speed of the cross flow fan 3 is constant and the amount of solar radiation in the cabin 23 is large. The air flow of the cross flow blower 3 is controlled so that the air flow of the cross flow blower 3 when blowing to the side is small and the air flow of the cross flow blower 3 when blowing to the side where the solar radiation amount of the cabin 23 is small is large. May be.

図18は、実施の形態3に係る車両用空調システムの構成の変形例を示す図である。例えば、図18における日射方向を示す矢印45のように、車両21の左側面に日光が多く当たっている場合には、制御部10は、客室23の左側の領域において横断流送風機の動きを示す矢印43Aの領域を横断流送風機3が揺動する際は、横断流送風機の吹き出し気流を示す矢印44Aのように風量が少なくなり、客室23の右側の領域において横断流送風機の動きを示す矢印43Bの領域を横断流送風機3が揺動する際は、横断流送風機の吹き出し気流を示す矢印44Bのように風量が多くなるように、横断流送風機3を動作させる。このような動作によっても、同様に客室23の空気の温度分布を均一にすることができる。   FIG. 18 is a diagram illustrating a modification of the configuration of the vehicle air conditioning system according to Embodiment 3. For example, as shown by the arrow 45 indicating the direction of solar radiation in FIG. 18, when a lot of sunlight hits the left side surface of the vehicle 21, the control unit 10 indicates the movement of the cross flow fan in the left side region of the cabin 23. When the cross flow fan 3 swings in the area indicated by the arrow 43A, the air volume decreases as indicated by the arrow 44A indicating the blown air flow of the cross flow fan, and the arrow 43B indicating the movement of the cross flow fan in the right area of the cabin 23. When the cross flow blower 3 swings in the region, the cross flow blower 3 is operated so that the amount of air increases as indicated by an arrow 44B indicating the blown air flow of the cross flow blower. Also by such an operation, the temperature distribution of the air in the cabin 23 can be made uniform in the same manner.

また、制御部10が、客室23の日射量が多い側に送風する際の横断流送風機3の揺動速度は速く、客室23の日射量が少ない側に送風する際の横断流送風機3の揺動速度は遅くなるように、横断流送風機3の送風動作を制御する場合について説明しているが、制御部10が、横断流送風機3の揺動速度は一定とし、客室23の日射量が多い側に送風する際の横断流送風機3の揺動量は少なく、客室23の日射量が少ない側に送風する際の横断流送風機3の揺動量は多くなるように、横断流送風機3の送風動作を制御してもよい。   In addition, the swinging speed of the cross flow fan 3 when the control unit 10 blows air toward the side of the cabin 23 where the amount of solar radiation is large is fast, and the swing of the cross flow fan 3 when air is blown toward the side of the cabin 23 where the amount of solar radiation is small. Although the case where the air blowing operation of the cross flow fan 3 is controlled so that the moving speed becomes slow has been described, the control unit 10 assumes that the swing speed of the cross flow fan 3 is constant and the amount of solar radiation in the cabin 23 is large. The cross-flow blower 3 has a small amount of rocking when it is blown to the side, and the cross-flow fan 3 is blown so that the amount of rocking of the cross-flow fan 3 when it is blown to the side of the cabin 23 where the amount of solar radiation is small is large. You may control.

図19は、実施の形態3に係る車両用空調システムの構成の変形例を示す図である。例えば、図19における日射方向を示す矢印45のように、車両21の左側面に日光が多く当たっている場合には、制御部10は、客室23の左側の領域において横断流送風機3が揺動する際は、横断流送風機の動きを示す矢印43Aのように揺動量が少なくなり、客室23の右側の領域において横断流送風機3が揺動する際は、横断流送風機の動きを示す矢印43Bのように揺動量が多くなるように、横断流送風機3を動作させる。このような動作によっても、同様に客室23の空気の温度分布を均一にすることができる。   FIG. 19 is a diagram illustrating a modification of the configuration of the vehicle air conditioning system according to Embodiment 3. For example, as shown by the arrow 45 indicating the solar radiation direction in FIG. 19, when a lot of sunlight hits the left side surface of the vehicle 21, the control unit 10 causes the cross flow blower 3 to swing in the left area of the cabin 23. When the cross flow blower 3 swings in the region on the right side of the cabin 23, the amount of swing is reduced as indicated by the arrow 43A indicating the movement of the cross flow blower. Thus, the cross flow blower 3 is operated so as to increase the swing amount. Also by such an operation, the temperature distribution of the air in the cabin 23 can be made uniform in the same manner.

また、制御部10が、客室23の日射状態に応じて、横断流送風機3の揺動速度と風量と揺動量のいずれかを制御する場合について説明しているが、全て又はいずれか2つを同時に制御してもよい。   Moreover, although the control part 10 has demonstrated the case where it controls either the rocking speed of the cross flow fan 3, the air volume, and the rocking amount according to the solar radiation state of the passenger room 23, all or any two are controlled. You may control simultaneously.

また、制御部10が、客室23を左側の領域と右側の領域に分けて領域毎に横断流送風機3の揺動速度又は風量又は揺動量を制御しているが、更に細かい領域に分けて横断流送風機3の揺動速度又は風量又は揺動量を制御してもよい。その場合には、車両21の日射量が多い側面に近い領域程、横断流送風機3の揺動速度が速く又は風量が少なく又は揺動量が少なくなるように制御する。また、客室23を領域に分けず、車両21の日射量が多い側面までの距離に応じて、横断流送風機3の揺動速度又は風量が連続的に変化するように制御してもよい。   In addition, the control unit 10 divides the cabin 23 into a left region and a right region and controls the swing speed, air volume, or swing amount of the cross flow fan 3 for each region. You may control the rocking | fluctuation speed, the air volume, or the rocking | fluctuation amount of the flow blower 3. FIG. In that case, the region closer to the side where the amount of solar radiation of the vehicle 21 is larger is controlled so that the swing speed of the cross flow blower 3 is faster, the air volume is smaller, or the swing amount is smaller. Moreover, you may control so that the rocking | fluctuation speed or the air volume of the crossflow fan 3 may change continuously according to the distance to the side surface with much solar radiation amount of the vehicle 21, without dividing the passenger room 23 into an area | region.

また、空気調和機2が暖房運転を行う際に、横断流送風機3が常に送風動作を行う場合について説明している。しかし、横断流送風機3が揺動しつつ送風を行うため、気流が乗客のそれぞれに直接当たる時間は短いものの、横断流送風機3が常に送風動作を行う場合には、乗客が気流を感じてしまい、快適性が損なわれる可能性がある。また、時間の経過に伴って、客室23の空気の温度分布は均一になるため、横断流送風機3の送風動作によって客室23の空気が攪拌・混合されなくても乗客の快適性が損なわれない可能性がある。そのため、制御部10は、例えば、図6に示すように、空気調和機2の暖房運転を開始した後、第1の所定の時間(ΔtON−1)だけ横断流送風機3の送風動作を行い、第1の所定の時間(ΔtON−1)が経過した後に横断流送風機3の送風動作を停止してもよい。また、制御部10は、例えば、図7に示すように、横断流送風機3の送風動作を停止して第2の所定の時間(ΔtOFF−2)が経過した後に、横断流送風機3の送風動作を再び開始させることを繰り返してもよい。 Moreover, when the air conditioner 2 performs heating operation, the case where the cross flow fan 3 always performs a blowing operation is described. However, since the crossflow blower 3 blows while swinging, the time for the airflow to directly hit each passenger is short, but when the crossflow blower 3 always performs the blowing operation, the passenger feels the airflow. The comfort may be impaired. In addition, since the temperature distribution of the air in the passenger compartment 23 becomes uniform over time, passenger comfort is not impaired even if the air in the passenger compartment 23 is not agitated and mixed by the air blowing operation of the cross flow fan 3. there is a possibility. Therefore, for example, as illustrated in FIG. 6, the controller 10 performs the air blowing operation of the cross flow fan 3 for the first predetermined time (Δt ON-1 ) after starting the heating operation of the air conditioner 2. The air blowing operation of the cross flow fan 3 may be stopped after the first predetermined time (Δt ON-1 ) has elapsed. Further, for example, as illustrated in FIG. 7, the control unit 10 stops the air blowing operation of the cross flow fan 3, and after the second predetermined time (Δt OFF−2 ) has elapsed, the air flow of the cross flow fan 3. You may repeat starting operation | movement again.
