Description

  The present invention relates to a vehicle body structure having a ventilation structure for air conditioning of a railway vehicle and an air conditioning method.

  As shown in FIGS. 5 and 6, the body of a limited express or express train is generally partitioned into a cabin a and an entrance b by a partition wall c as shown in FIGS. 5 and 6, and the partition wall c enters and exits the cabin. For this reason, a partition door 1 is provided (for example, see Non-Patent Document 1). The partition door l is opened automatically or manually when entering or leaving the cabin a, but is usually closed automatically or manually. For this reason, it is considered that air does not enter or exit between the guest room a and the entrance / exit b, and the air flow is indicated by an arrow in the ventilation structure d as schematically shown in FIG. The conditioned air is directly supplied to both the entrance / exit platform b and the exhaust air is exhausted directly from both the cabin a and the entrance platform b, thereby air-conditioning the cabin a and the entrance platform b without the influence of the partition. . However, the exhaust from the cabin a and the entrance / exit b is set to a level corresponding to the replenishment amount of fresh air in a part of the supply air, and the rise of air conditioning is accelerated by circulating the remaining exhaust air as return air. To save energy. For this reason, the ventilation structure d has air supply ports e and f to the cabin a and the entrance / exit b, exhaust ports g and h from the cabin a and the entrance / exit b, and the fresh air introduction port i, the cabin a and A return air path j from the entrance / exit base b and an exhaust port k outside the vehicle body are provided.

Further, as shown in FIG. 7, in a vehicle body having a toilet p at the entrance / exit b, ventilation is performed by removing air from the entrance / exit to the toilet and from the toilet to the outside of the vehicle as shown by arrows to eliminate odors. ing. However, the temperature adjustment of the entrance / exit platform b is insufficient to adjust the temperature with the amount of air discharged via a toilet or the like. For this reason, it is necessary to return the air in the entrance / exit b to the cabin a, and circulating a large amount of air using the capacity of the air conditioner is an important matter for adjusting the temperature inside the vehicle, while the air to be discharged Adjusting the interior environment by reducing the amount leads to a reduction in energy loss. Therefore, a louver q and a fan r as shown in FIG. 8 are provided on the partition wall c and air is actively returned to the air conditioner. Energy saving is also done by adopting a mechanism.

  By the way, in the recent demand for further simplification of the vehicle body and cost reduction, when considering the air conditioning in the vehicle, the entrance / exit b provided in the express and express vehicles opens the side entrance door m when passengers get on and off. However, there are few stops and the opening time per unit time is short. Therefore, it can be said that the air conditioning in the cabin a is not significantly affected. In addition, the partition door l is opened at times other than when getting on and off, and there is air movement between the passenger compartment a and the entrance / exit base b. However, the effect on the air conditioning of the passenger compartment a is that the side entrance door m of the entrance / exit base b is opened. Even smaller than that.

  If this is made into the partition structure which partitions off the cabin a and the entrance / exit stand b completely like the past, the supply rate of the conditioned air into the entrance / exit stand b is made higher than the inside of the cabin a, and the side entrance m is opened. Although it is advantageous for individual air conditioning such as considering the fact that the actual situation is less effective, air supply and exhaust are independently performed in both the guest room a and the entrance / exit b on the complete partition structure. In addition to complicating the ventilation structure d, it is necessary to make an effort to fit together the partition wall c and the vehicle body, and the interior processing including the seam including adjustment of the gap portions of the both sides including adjustment for dimensional errors. As a result, both boundary structures become complicated and expensive. In addition, it is not often performed to individually control the air-conditioning of the individual spaces such as the cabin a and the entrance / exit b with the individual air-conditioners, and as shown in FIG. In general, air conditioning is shared by air conditioners, and it is difficult to equalize the air-conditioning environment between the cabin a and the entrance / exit platform b. End up.

  Further, in the air conditioning including the influence of the exhaust of the toilet p, when a mechanism for actively returning from the entrance / exit b to the cabin a as shown in FIG. 8 is adopted, the return air has a high wind speed and a large temperature difference. Thus, passengers who come into contact with the return air feel a draft of the air and a temperature difference, which causes problems such as a draft.

  Therefore, as a result of repeated simulations and examinations on the partition structure and the ventilation structure, the present inventors have found that an appropriate return between the passenger cabin and the entrance / exit is shown instead of the positive air return as shown in FIG. It has been found that by simply ventilating, the structure can be simplified, the weight can be reduced, and the cost can be reduced by ensuring the visibility of the partition and equalizing the air conditioning environment.

  An object of the present invention is to provide a vehicle body structure and an air conditioning method for a railway vehicle that can simplify the structure, reduce the weight, and reduce the cost by ensuring the visibility limitation by partitioning and equalizing the air conditioning environment based on such new knowledge. Is to provide.

  In order to achieve the above-described problems, the vehicle body structure of the railway vehicle according to the present invention air-conditions the interior of the vehicle by partitioning the interior of the vehicle into a guest room and an entrance / exit, and supplying and exhausting conditioned air into the interior of the vehicle. One feature of the vehicle body structure of a railway vehicle provided with a ventilation structure is that a space is formed on the ceiling side of the partition wall.

  In such a configuration, when air-conditioning the interior of the vehicle by supplying and exhausting conditioned air into the vehicle, the space provided on the ceiling side of the partition wall is a partial ventilation portion of the partition between the guest room and the entrance / exit Since the air supply and exhaust air that is designed in the guest room can be efficiently applied to the entrance / exit side, which has an extremely small volume with respect to the guest room, the supply / exhaust of the individual air supply and exhaust is reduced or omitted on that side. Air conditioning can be achieved. At the same time, the vacant space as described above causes a reduction in the area of the partition wall, and the mating joint area including adjustment of the dimensional error between the outer periphery of the partition wall and the vehicle body by vacating the boundary with the ceiling side. And shortening the interior treatment area of the roof. Moreover, the vacant space is on the ceiling side and does not impair the visibility restriction between the guest room and the entrance / exit, and the air conditioning environment is moderately even while suppressing the influence on the guest room when the entrance / exit door on the entrance / exit is opened. Can be realized. Furthermore, the air returning from the access platform to the cabin through the empty space on the ceiling side flows along the ceiling inner surface due to the viscosity, that is, flows back on the non-residential space side above the living space where the passengers live. As a result, passengers who have arisen in the case of the conventional return method can feel a draft of air and a temperature difference, thereby solving problems such as a draft.

  The vehicle body structure of the railway vehicle according to the present invention also includes a passenger compartment and an entrance / exit that are partitioned by a partition wall, and a ventilation structure that air-conditions the interior of the vehicle by supplying and exhausting conditioned air. In the body structure of a railway vehicle, a space is formed on the ceiling side of the partition wall, and the ventilation structure has an air supply opening to the passenger compartment in the passenger compartment and the entrance / exit, and an exhaust outlet from the passenger compartment in the passenger compartment. It has the characteristics of

In such a configuration, when air-conditioning the interior of the vehicle by supplying and exhausting conditioned air into the vehicle, the space provided on the ceiling side of the partition wall is a partial ventilation portion of the partition between the guest room and the entrance / exit As the conditioned air is directly supplied to both the guest room and the entrance / exit from both of the air intakes, the exhaust from the exhaust port in the guest room is efficiently supplied to the entrance / exit side where the volume is extremely small compared to the guest room. Therefore, air conditioning can be achieved by omitting direct exhaust from the entrance / exit platform side. At the same time, the vacant space as described above causes a reduction in the area of the partition wall, and the mating joint area including adjustment of the dimensional error between the outer periphery of the partition wall and the vehicle body by vacating the boundary with the ceiling side. Both the interior treatment area and the weathering are shortened. In addition, the space on the ceiling side does not impair the view restriction between the guest room and the entrance and exit, and the air conditioning environment is moderately balanced while suppressing the impact on the guest room when the entrance door is opened. I can plan. In this case, in particular, the air flow from the entrance / exit to the entrance / exit base side to the guest room / exhaust vent side from the entrance / exit to the guest room / exhaust vent is positively realized. A part of the flow of air returning to the cabin along the way is mixed and stirred with the cabin air,
Along with the appropriate equalization of the air-conditioning environment, the passengers who have occurred in the case of the conventional return method can feel the draft of the air and the temperature difference, so that problems such as drafts can be solved.

The space on the ceiling side of the partition wall is formed at the boundary between the upper part of the partition wall and the ceiling surface.
It is possible to cope with a simple structure in which the upper part of the partition wall is made lower than the ceiling side, and it is possible to omit both the roof structure having a complicated shape and the connection structure with the ceiling surface and the roof interior structure.

  According to the vehicle body structure of a railway vehicle of the present invention, in particular, the vehicle body structure of the railway vehicle having the other feature described above, the railway vehicle that air-conditions the interior of the vehicle partitioned by the partition wall into the cabin and the entrance / exit through the ventilation structure provided in the vehicle body. In the air conditioning method of the above, while supplying conditioned air to both the guest room and the entrance / exit through the ventilation structure, from the guest room directly from the guest room, through the empty part on the ceiling side provided in the upper part of the partition wall, from the guest room An air conditioning method for a railway vehicle characterized by exhausting and air-conditioning the inside of the vehicle is realized.

  Further objects and features of the present invention will become apparent from the following detailed description and drawings. Each feature of the present invention can be used alone or in combination in various combinations as much as possible.

  According to the vehicle body structure and the air conditioning method of the railway vehicle of the present invention, the space between the passenger compartment and the entrance / exit is partly omitted on the ceiling side, and ventilation is lost, which impairs visibility restrictions and opens the air conditioning area. The air conditioning can be achieved almost evenly at low cost with a simple partitioning structure and ventilation structure by omitting at least the exhaust of the supply and exhaust of conditioned air for air conditioning the interior of the vehicle. it can. At the same time, the weight can be reduced by omitting a part of the partition wall, which is advantageous for further speeding up.

  The vehicle body structure of a railway vehicle according to the present invention includes a partition wall 3 that partitions the interior of the vehicle into a cabin 1 and an entrance / exit 2 in a vehicle body 7 as schematically shown in FIG. 1, and supplies and exhausts conditioned air into the vehicle. And a ventilation structure 4 for air conditioning the interior of the vehicle.

  Side entrance doors 5 as shown in FIG. 2 are provided on the left and right sides of the entrance / exit platform 2, and partition doors 6 are provided on the partition walls 3. If the entrance / exit platform 2 is a connecting platform, a through door (not shown) is also provided on the front side. As shown in the schematic diagram of FIG. 1, the ventilation structure 4 is provided with an air supply port 11 branched from the exhaust port 10 a of the air conditioner 10, an exhaust port 12 from the vehicle interior, and an exhaust port 13 to the outside of the vehicle. The machine 10 is provided with a fresh air inlet 10b and a return air inlet 10c from the vehicle interior. There are various types of air-conditioning ventilation systems such as dispersion on the roof, concentration on the roof, concentration on the roof, on the floor, and under the floor, and a duct is used in many cases. Ducts include a form extending in the longitudinal direction of the car body under the floor or in the center or both sides of the floor, the center part on the roof, and the center part on the ceiling, and standing up between the windows of the side structure. In addition, ventilation is performed along with air conditioning, and there are various types such as an independent ventilation system and a fresh air intake function by the air conditioner 10.

  However, the specific method and structure beyond the basic structure described above are not particularly questioned, and it is characterized in that a space 22 as illustrated in FIGS. 1 and 2 is formed on the ceiling 21 side of the partition wall 3. . Thereby, when air-conditioning the inside of the vehicle with the air supply indicated by the arrow 23 of the conditioned air and the exhaust indicated by the arrow 24 in the vehicle, the space 22 provided on the ceiling 21 side of the partition wall 3 becomes the cabin 1 and the entrance / exit. 2 functions as a partial ventilation part in the partition part 25 by the partition wall 3. Therefore, the air supply and exhaust air to be achieved on the cabin 1 side can be efficiently exerted on the entrance / exit platform 2 side having an extremely small volume with respect to the cabin 1. As a result, air conditioning can be achieved on the entrance / exit 2 side by reducing or omitting independent air supply or exhaust. At the same time, the vacant space 22 as described above reduces the area of the partition wall 3, and by adjusting the boundary portion with the ceiling 21 side to the vacant space 22, adjustment of the partition wall 3 outer periphery and the vehicle body 7 with respect to mutual dimensional errors, etc. Both the mating joint area and the interior treatment area of the cover are shortened. Moreover, the vacant space 22 is located on the ceiling 21 side and does not impair the view restriction between the guest room 1 and the entrance 2 and suppresses the influence on the guest room 1 when the side entrance door 5 of the entrance 2 is opened. Appropriate equalization of the air-conditioning environment can be achieved. Further, the air 26a returning from the entrance 2 to the passenger compartment 1 through the empty space 22 on the ceiling inner surface 21a side flows and returns along the ceiling inner surface 21a due to viscosity as shown in FIG. Since the air flows through the non-residential space above the living space and is returned, the passengers who have occurred in the case of the conventional return method can feel the draft of the air and the temperature difference, and solve problems such as drafts. it can.

  In summary, the partition wall 3 between the guest room 1 and the entrance / exit platform 2 is partly omitted on the ceiling 21 side, and ventilation is caused by the space 22 to impair the view restriction by the partition wall 3 and to reduce the air conditioning area. Without opening, at least the exhaust and supply of conditioned air for air conditioning the interior of the vehicle is omitted on the entrance / exit 2 side, and air conditioning is inexpensive with a simple partition structure and ventilation structure 4. It is possible to achieve almost evenly in both the guest room 1 and the entrance / exit platform 2 without any influence. At the same time, it is possible to reduce the weight by partially omitting the partition wall 3, which is advantageous in meeting the recent demand for higher speed.

  In order to realize this, in the present embodiment, as shown in FIG. 1, the ventilation structure 4 further has an air supply port 11 to the interior of the vehicle 1 and the entrance / exit 2 and an exhaust port 13 from the interior of the vehicle. 1 and the exhaust port 13 is omitted from the access table 2. Along with this, the exhaust duct can be shortened. As a result, while the conditioned air is supplied to both the guest room 1 and the entrance / exit 2 directly from the air supply port 11 as indicated by the arrow 23, the exhaust indicated by the arrow 24 by the exhaust port 13 in the guest room 1 is supplied to the guest room 1. Therefore, air conditioning can be achieved by efficiently exerting on the entrance / exit 2 side whose volume is extremely smaller than 1 and omitting direct exhaust from the entrance / exit 2 side.

  In short, the entrance / exit 2 does not have the exhaust port 13 and continues to be supplied from the air supply port 11, and a part of the air is introduced into the return air introduction port 10 c, but the return ratio with respect to the supply air flow rate is limited by the setting. Therefore, the amount of conditioned air in the entrance / exit 2 becomes excessive as time passes, and a predetermined amount of exhaust corresponding to the entire vehicle is exhausted to the side of the cabin 1 where the conditioned air becomes insufficient over time. Since it is pushed out through the empty space 22 as indicated by the arrow 26a, the exhaust in the entrance / exit 2 is reliably achieved at a predetermined rate. At this time, the temperature distribution in the entrance / exit platform 2 tends to be constant due to the alternating current of the conditioned air supply air flow, the return air flow, and the extrusion flow to the cabin 1, and the cabin 1 side of the conditioned air in the entrance / exit platform 2 The temperature distribution in the cabin 1 tends to be uniform due to the exchange of the conditioned air flow into the cabin, the conditioned air flow into the cabin 1 and the conditioned air in the cabin 1. Moreover, since the conditioned air on the cabin 1 side flows into the entrance / exit 2 side as indicated by the arrow 26b and exchanges between the cabin 1 and the entrance / exit 2 due to the equilibrium action of the conditioned air, the cabin 1 and the entrance 2 It is easy to equalize the air conditioning between. In particular, while positively realizing the return of air 26a from the entrance 2 to the guest room 1, the ventilation path from the entrance 1 to the guest room 1 and the exhaust port 13 from the guest room 1 to the entrance 2 side is also provided. Since a part of the flow of the air 26a returning to the cabin 1 along the ceiling inner surface 21a is mixed and agitated with the cabin air, the conventional air conditioning environment is moderately equalized. Passengers who have occurred in the case of the return method can feel the draft feeling and temperature difference of the air 26a, and can solve problems such as a draft.

  Further, as shown in FIGS. 1 and 2, the space 22 on the ceiling 21 side of the partition wall 3 is formed at the boundary between the upper part of the partition wall 3 and the ceiling inner surface 21a, so that the upper part of the partition wall 3 is It can be handled with a simple structure that is lower than the ceiling 21 side, has a complicated curved shape, and has a roof structure with different shape and height depending on the vehicle type and a ceiling structure and a ceiling interior structure. There is an advantage that both can be omitted. From this point of view, it is preferable that the empty space 22 has a height range below the corner portion of the vehicle body formed by the ceiling structure and the side structure as illustrated in FIG. However, this height range only needs to be satisfied at the side edge portion for fitting and joining the partition wall 3 with the vehicle body 7 and the interior finish processing of the partition wall, and the shape of the upper end is not particularly questioned, and the empty space 22 is ventilated. It can be a ventilation structure or a decoration structure that does not hinder, and such a structure is attached to the partition wall 3 itself or a window-shaped space 22 formed integrally with the partition wall 3. It can also be made to be. However, in order to simplify the assembly structure, it is preferable that the part integrated with the partition wall 3 has a positional relationship that can eliminate the fitting connection with the vehicle body 7 and the cover interior treatment, that is, a structure having a gap. It is.

  According to the vehicle body structure of the railway vehicle according to the present embodiment as described above, the interior of the vehicle partitioned by the partition wall 3 into the cabin 1 and the entrance / exit platform 2 can be air-conditioned through the ventilation structure 4 provided in the vehicle body 7. While supplying conditioned air to both the guest room 1 and the entrance / exit 2 through the ventilation structure 4, the guest room 1 directly passes from the guest room 1 through the empty 22 part on the ceiling 21 side of the partition wall 3 from the guest room 1. An air conditioning method for a railway vehicle that exhausts and air-conditions the inside of the vehicle is realized, and the above-described operational effects can be obtained.

  INDUSTRIAL APPLICABILITY The present invention can be practically used for the body of a railway vehicle and its air conditioning, and is advantageous for equalizing the structure, cost, and air conditioning.
