Description

本発明は、空調装置を搭載した鉄道車両に関し、特に、吹出し口とリターン口とを車内の天井に配設し、リターン口と並んだ吹出し口からの吹き出し方向を調整した鉄道車両に関する。   The present invention relates to a railway vehicle equipped with an air conditioner, and more particularly, to a railway vehicle in which a blowout port and a return port are arranged on a ceiling in the vehicle, and a blowing direction from the blowout port aligned with the return port is adjusted.

従来より、鉄道車両には、車内に調和空気を送風する空調装置が搭載されており、例えば、特許文献１に開示された鉄道車両では、空調装置で調整した調和空気を車内に吹出す吹出し口と、車内の空気を空調装置内に吸入するリターン口とが天井に配設されている。吹出し口は、車両の前後方向に２列に配置され、空調装置からダクトを通じて吹出し部に送風された調和空気が、吹出し口から車内に向けて吹き出すようになっている。一方、車内の空気はリターン口から吸い込まれる。   Conventionally, an air conditioner that blows conditioned air into the vehicle is mounted on the railway vehicle. For example, in the railway vehicle disclosed in Patent Document 1, a blowout port that blows out conditioned air adjusted by the air conditioner into the vehicle. And a return port for sucking the air in the vehicle into the air conditioner is provided on the ceiling. The outlets are arranged in two rows in the front-rear direction of the vehicle, and conditioned air blown from the air conditioner through the duct to the outlet is blown out from the outlet toward the interior of the vehicle. On the other hand, the air in the vehicle is sucked from the return port.

特開２００２−３４７６１７号公報JP 2002-347617 A

しかしながら、従来の鉄道車両では、調和空気が天井の吹出し口から床に向けて真下に吹き出されるが、リターン口が並んで配設され吹出し口かの調和空気は、一部がそのままリターン口に吸い込まれてしまう。従って、こうした短絡現象が生じることにより、空調装置からの調和空気がそのまま排気されてしまい無駄が生じてしまうとともに、冷気や暖気である調和空気が車内の乗客に十分に届かないことによって、空調システムの効率を低下させていた。   However, in conventional railway vehicles, conditioned air is blown directly down from the ceiling outlet to the floor, but the return openings are arranged side by side, and some of the conditioned air at the outlet is directly at the return openings. I will be sucked. Therefore, when such a short-circuit phenomenon occurs, the conditioned air from the air conditioner is exhausted as it is and wasteful, and the conditioned air, which is cold air or warm air, does not reach the passengers in the vehicle sufficiently. Had reduced the efficiency.

そこで、本発明は、かかる課題を解決すべく、吹出し口から吹き出した調和空気が車内に効率よく送り出されるようにした鉄道車両を提供することを目的とする。   Therefore, an object of the present invention is to provide a railway vehicle in which conditioned air blown out from a blow-out port is efficiently sent out into the vehicle in order to solve such a problem.

本発明に係る鉄道車両は、空調装置からの調和空気を車内に吹出す吹出し口と、車内の空気を吸い込むリターン口とが天井に形成されたものであって、前記リターン口に並んで位置する吹出し口が形成された吹出し部は、前記空調装置から送られた調和空気を前記リターン口から遠ざかる方向に吹き出させる吹出し手段を有するものであることを特徴とする。
また、本発明に係る鉄道車両は、前記吹出し部が、前記空調装置からの調和空気を送るダクトに連通した空間であって、その内部に前記リターン口から遠ざかる方向に流れるように調和空気を導く整流板が設けられたものであることが好ましい。 The railway vehicle according to the present invention has a blowout port for blowing conditioned air from the air conditioner into the vehicle and a return port for sucking the air in the vehicle formed on the ceiling, and is aligned with the return port. The blow-out section in which the blow-out opening is formed has blow-out means for blowing out conditioned air sent from the air conditioner in a direction away from the return opening.
In the railcar according to the present invention, the blowout part is a space communicating with a duct for sending conditioned air from the air conditioner, and guides the conditioned air to flow in a direction away from the return port. It is preferable that a current plate is provided.

よって、本発明の鉄道車両によれば、一部の吹出し口では、吹出し部から送風する調和空気の吹出し方向がリターン口から遠ざかる方向であるので、吹出し口から送風した調和空気のうち、一部の調和空気が、そのままリターン口に向かって空調装置内に戻されること、いわゆる短絡現象の発生を回避することができる。したがって、リターン口と並んだ吹出し口からでも、そこから吹き出した冷気や暖気の調和空気が十分に車内に送り出される。また、本発明の鉄道車両では、吹出し部に整流板を設けるだけの簡単な構成によって安価に上記効果を達成できる。   Therefore, according to the railway vehicle of the present invention, at some outlets, the direction of the conditioned air blown from the outlet is the direction away from the return port, so a part of the conditioned air blown from the outlet It is possible to avoid the occurrence of a so-called short-circuit phenomenon in which the conditioned air is directly returned into the air conditioner toward the return port. Therefore, the conditioned air of the cool air and the warm air blown out from the blow-out port aligned with the return port is sufficiently sent into the vehicle. Moreover, in the railway vehicle of this invention, the said effect can be achieved at low cost by the simple structure which only provides a baffle plate in the blowing part.

次に、本発明にかかる鉄道車両の一の実施形態を図面を参照しながら以下に説明する。図１は、鉄道車両の車内の天井を示す図であり、車内側から見た平面図である。図２は、図１のＡ−Ａ矢視断面図であるが、図１において中心線ＣＬで左右対称であるため左半分のみ示している。図３は、図１のＢ−Ｂ矢視断面図であるが、図２と同様に左半分のみ示している。   Next, one embodiment of a railway vehicle according to the present invention will be described below with reference to the drawings. FIG. 1 is a diagram showing a ceiling in a vehicle of a railway vehicle, and is a plan view seen from the inside of the vehicle. FIG. 2 is a cross-sectional view taken along the line AA in FIG. 1, but only the left half is shown because it is symmetrical with respect to the center line CL in FIG. 3 is a cross-sectional view taken along the line B-B in FIG. 1, and only the left half is shown in the same manner as FIG. 2.

本実施形態の鉄道車両１は、図２に示すように、車内１１の天井には天井板１０と屋根構体４０との間に空間１０Ｓが構成され、車両長手方向に直線状に延びるダクト５２が設置されている。ダクト５２は、空調装置６０からの調和空気ＣＡを送るためのものであって、分割された複数の吹出し部５１へ、仕切り板５３の流入孔５３Ｈを通して連通している。そして、調和空気ＣＡが吹き出る吹出し口２０は、図１に示すように中心線ＣＬを挟んだ２列で構成され、鉄道車両１の天井に車内全体にわたってのびている。これに対し、車内の空気を吸い出すリターン口３０は、中心線ＣＬから見て吹出し口２０の外側にあって、所定の間隔をあけて長手方向の２カ所に配置されている。   As shown in FIG. 2, the railcar 1 of the present embodiment has a space 10 </ b> S formed between the ceiling plate 10 and the roof structure 40 on the ceiling of the vehicle interior 11, and a duct 52 that extends linearly in the longitudinal direction of the vehicle. is set up. The duct 52 is for sending the conditioned air CA from the air conditioner 60, and communicates with the plurality of divided outlets 51 through the inflow holes 53H of the partition plate 53. And the blower outlet 20 which the conditioned air CA blows off is comprised by 2 rows on both sides of the centerline CL, as shown in FIG. On the other hand, the return ports 30 for sucking out the air in the vehicle are located outside the outlet 20 as viewed from the center line CL, and are arranged at two positions in the longitudinal direction with a predetermined interval.

ここで、複数の吹出し口２０のうち、リターン口３０と隣り合ったものを吹出し口２０Ａとし、そうでないリターン口３０と離れた位置にあるものを吹出し口２０Ｂとして区別がされている。本実施形態では、こうして区別した吹出し部２０Ａと２０Ｂとで調和空気ＣＡの吹出し方向が異なる方向になるように構成されている。   Here, among the plurality of outlets 20, the one adjacent to the return opening 30 is defined as the outlet 20 </ b> A, and the one located away from the other return opening 30 is distinguished as the outlet 20 </ b> B. In this embodiment, it is comprised so that the blowing direction of the conditioned air CA may differ in the blowing parts 20A and 20B which were distinguished in this way.

先ず、吹出し口２０Ａが形成された吹出し部５１Ａでは、調和空気ＣＡの吹出し方向ＦＤが、図２に示すように、リターン口３０から遠ざかる中心線ＣＬ側に向くように構成されている。具体的には、吹出し部５１Ａには、中心線ＣＬ側に傾斜した整流板５６が設けられている。この整流板５６は、仕切り板５３に固定して形成され、その傾斜に沿ってリターン口３０から遠ざかる中心線ＣＬ側へと調和空気ＣＡの流れをつくるようにしたものである。   First, in the blowout part 51A in which the blowout opening 20A is formed, the blowout direction FD of the conditioned air CA is configured to face the center line CL side away from the return opening 30 as shown in FIG. Specifically, a rectifying plate 56 that is inclined toward the center line CL is provided in the blowing portion 51A. The rectifying plate 56 is formed fixed to the partition plate 53, and is adapted to create a flow of conditioned air CA toward the center line CL that moves away from the return port 30 along its inclination.

その一方で、吹出し口２０Ｂが形成された吹出し部５１Ｂでは、吹出し口２０Ｂから車内１１に吹出す調和空気ＣＡの吹出し方向ＦＤは、図３に示すように、真下に向けた方向となっている。すなわち、ダクト５２から流入孔５３Ｈを通じて吹出し部５１Ｂに流入した調和空気ＣＡは、その空間からそのまま吹出し口２０Ｂを通って車内１１に吹出すため、真下に向けた流れになっている。   On the other hand, in the blowout part 51B in which the blowout opening 20B is formed, the blowout direction FD of the conditioned air CA blown out from the blowout opening 20B into the vehicle interior 11 is a direction directed directly downward as shown in FIG. . That is, the conditioned air CA that has flowed from the duct 52 into the blowing portion 51B through the inflow hole 53H is directly blown out of the space through the blowout port 20B and into the vehicle interior 11, and thus flows downward.

よって、本実施形態の鉄道車両では、空調装置６０で生成された調和空気ＣＡはダクト５２を介して各吹出し部５１Ａ，５１Ｂへと送り込まれ、そこから吹出し口２０Ａ，２０Ｂを介して車内へ吹き出される。その際、裾広がりになった吹出し口２０Ｂからは、車体幅方向に広がるようになりながらも、真下に向けた流れを主流として調和空気ＣＡが車内１１に吹き出される。   Therefore, in the railway vehicle according to the present embodiment, the conditioned air CA generated by the air conditioner 60 is sent to each of the outlets 51A and 51B via the duct 52, and then blown out into the vehicle via the outlets 20A and 20B. Is done. At that time, the conditioned air CA is blown out into the vehicle interior 11 from the outlet 20B having a wider hem, with the flow directed downwardly as the mainstream while spreading in the vehicle body width direction.

そして、同様にダクト５２を介して調和空気ＣＡが送り込まれた吹出し部５１Ａでは、整流板５６によって調和空気ＣＡの流れがつくられ、吹出し口２０Ａからは、リターン口３０から遠ざかる中心線ＣＬ側への流れを主流とした調和空気ＣＡが車内１１に吹き出される。従って、近い位置でリターン口３０から車内空気の吸い込みを行っているが、吹出し口２０Ａから吹出された調和空気ＣＡは、従来のようにその多くがリターン口３０に吸い取られてしまうことなく、車内１１に吹き出されるようになった。なお、仕切り板５３が、整流板５６に連続する流入孔５３Ｈの面板（５３Ｈの符号が付されたもの）と９０度である場合に良い結果が得られた。   Similarly, in the blowout part 51A into which the conditioned air CA is sent through the duct 52, a flow of the conditioned air CA is created by the rectifying plate 56, and from the blowout opening 20A to the center line CL side away from the return opening 30. The conditioned air CA having the main flow is blown into the vehicle interior 11. Accordingly, air in the vehicle is sucked from the return port 30 at a close position, but most of the conditioned air CA blown from the air outlet 20A is not sucked into the return port 30 as in the prior art. 11 was blown out. In addition, a good result was obtained when the partition plate 53 was 90 degrees with the face plate of the inflow hole 53H continuing to the rectifying plate 56 (the one marked with the reference numeral 53H).

よって、吹出し口２０Ａから吹き出された調和空気ＣＡも、他の吹出し口２０Ｂから吹き出された調和空気ＣＡと同様に、適量が車内１１下方の座席に座る乗客の位置までも届くようになり、乗客にとって快適な環境を提供することができる。
ここで、図４は、吹出し口２０Ａから吹き出した調和空気（冷気）ＣＡの流れと温度分布との関係についてシュミレーション結果を示した図である。吹出し口２０Ａから吹き出された調和空気ＣＡの流れを矢印で示すと共に、吹出し口２０Ａ部分の断面において生じた車内の温度分布がＡ〜Ｇ層で示されている。温度分布はＡ〜Ｇ層にかけて温度が高くなっている。 Therefore, the conditioned air CA blown out from the outlet 20A reaches the position of the passenger sitting on the seat below the interior 11 as well as the conditioned air CA blown out from the other outlet 20B. A comfortable environment can be provided.
Here, FIG. 4 is a diagram showing a simulation result of the relationship between the flow of conditioned air (cold air) CA blown out from the outlet 20A and the temperature distribution. The flow of the conditioned air CA blown out from the outlet 20A is indicated by arrows, and the temperature distribution in the vehicle generated in the cross section of the outlet 20A is indicated by layers A to G. In the temperature distribution, the temperature increases from the A to G layers.

図示した矢印から分かるように、左右両側の吹出し口２０Ａから幅方向中央に向けた吹出し方向ＦＤの調和空気ＣＡは、互いにぶつかり合って乗客の居る下方に降り、中央から窓側１３へと回り込んでリターン口３０へと吸い上げられる流れがつくられている。そして、温度分布からは、中央部分に吹き出された冷気が下方に降りるとともに窓側１３に広がって車内１１全体を効率良く冷やしていることが分かる。また、本実施形態では、こうした効果が、吹出し部５１Ａに設けた整流板５６による簡単且つ安価な構成によって達成できる。   As can be seen from the illustrated arrows, the conditioned air CA in the blowing direction FD from the left and right blowing outlets 20A toward the center in the width direction collides with each other and descends to the lower side where the passengers are present, and wraps around the window side 13 from the center. A flow is drawn up to the return port 30. From the temperature distribution, it can be seen that the cold air blown to the central portion descends downward and spreads to the window side 13 to cool the entire interior 11 efficiently. Further, in the present embodiment, such an effect can be achieved by a simple and inexpensive configuration by the rectifying plate 56 provided in the blowing portion 51A.

そして、詳しく図示しないが、リターン口３０が隣にない吹出し口２０Ｂからは、調和空気ＣＡが真下に吹き出され、同じように乗客の居る下方へと降りて窓側１３へと回り込んでリターン口３０へと吸い上げられ、温度分布は、中央部分から下方に降りる際に窓側１３へと広がって車内１１全体を効率良く冷やしている。よって、本実施形態の鉄道車両では、リターン口３０の影響を受けた空調ムラをなくし、車内全体を快適にすることが可能になった。   Although not shown in detail, the conditioned air CA is blown directly down from the outlet 20B where the return port 30 is not adjacent, and similarly descends to the lower side where the passengers are present and wraps around the window side 13 to return the return port 30. The temperature distribution spreads to the window side 13 when descending from the central portion and cools the entire interior 11 efficiently. Therefore, in the railway vehicle according to the present embodiment, it is possible to eliminate the air conditioning unevenness affected by the return port 30 and to make the entire interior comfortable.

以上、本発明に係る鉄道車両について実施形態を説明したが、本発明は前記実施形態に限定されるものではなく、その要旨を逸脱しない範囲で様々な変更が可能である。
例えば、実施形態では、リターン口２０を天井板１０に４箇所設けた鉄道車両１を例示したが、リターン口の数量や、リターン口を配置する位置は、適宜変更可能である。
また、吹出し部５１Ａに整流板５６を設けることにより吹出し方向ＦＤを調整するようにしたが、ダクト５２から吹出し口２０Ａへの流路を形成するようにしてもよい。 As mentioned above, although embodiment was described about the rail vehicle which concerns on this invention, this invention is not limited to the said embodiment, A various change is possible in the range which does not deviate from the summary.
For example, in the embodiment, the railway vehicle 1 in which the return ports 20 are provided at four places on the ceiling board 10 is illustrated, but the number of return ports and the position where the return ports are arranged can be changed as appropriate.
Moreover, although the blowing direction FD was adjusted by providing the baffle part 56 in the blowing part 51A, you may make it form the flow path from the duct 52 to the blowing port 20A.
