Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an air conditioning method particularly suitable for rail vehicles with short distances between stations, such as railways, subways, elevated tracks, mole rails, and streetcars.

(Prior Art) In conventional rail vehicles, as shown in FIGS. 4 and 5, an air conditioner 102 is mounted on the upper part of each vehicle 01, and cold air and warm air generated by the air conditioner 02 are Conditioned air such as
The air is blown inward to cool and heat the interior of the vehicle compartment 05.

(Problems to be Solved by the Invention) In the case of relying on the conventional air conditioning method described above, even though air conditioning is not required throughout the year, each vehicle 01 is always equipped with an air conditioning device 02. Not only does the cost increase, but also the weight of each vehicle 01 increases by the weight. If the weight of the vehicle O1 increases, the vehicle body, truck, etc. must be made stronger, which increases the manufacturing cost of the vehicle 01 and also increases the operating cost.

In addition, in subway cars, the air conditioner is 0 when cooling.
This air conditioning method cannot be adopted because the heat emitted from the tunnel is accumulated in the tunnel.

Furthermore, in elevated track vehicles, there is a problem in that if drainage generated during cooling is discharged to the outside, it pollutes the living environment under the tracks.

(Means for Solving the Problems) The present invention was invented to solve the above problems, and its gist is to provide a conditioned air generator installed at a predetermined location such as a station. The present invention provides an air conditioning method for a railway vehicle, characterized in that the conditioned air generated in the above is supplied to the cabin of a railway vehicle parked at a predetermined stopping position through an expandable supply duct.

(Function) Since the present invention has the above-mentioned configuration, when a railway vehicle is stopped at a predetermined stopping position at a station, etc., air is generated by the conditioned air generator installed at a place corresponding to this stopping position during the stopping time. The conditioned air is supplied to the vehicle interior through a supply duct.

Then, the vehicle is run with the conditioned air sealed inside the vehicle, and the above process is repeated when the vehicle stops at the next station or the like.

(Example) An example of the present invention will be specifically described with reference to FIGS. 1 to 3.

1 is a track vehicle, and this track vehicle 1 is not equipped with an air conditioner like conventional ones, but there is an air intake port 2 opened on the upper side of the vehicle 1, and an air intake port 2 on the back of the ceiling 4 of the vehicle compartment 3. The formed air chamber 5, the air intake duct 6 that communicates the air intake port 2 and the air chamber 5, the plurality of air blowing lowers provided on the ceiling 4 that communicate the air chamber 5 with the inside of the vehicle interior 3, and the air intake port. The shutter 8 is provided at 2. Reference numeral 10 denotes a conditioned air generator installed at a predetermined location near the tracks at the station.
The air conditioner 11 includes an air conditioner 11, a blower 12, a shutter 13, an expandable supply duct 14, and an air outlet 15 provided at the tip of the supply duct eye 4. In addition, Figures 2 and 3
In the figure, the dashed line indicates the vehicle limit.

When the vehicle 1 arrives at the station, it is stopped at a predetermined stopping position by a fixed-point stopping device or the like, that is, at a position where its air intake port 2 faces the air outlet port 15 of the conditioned air generator 10. Next, the supply duct 4 is extended so as to leave the space shown in FIG. 2, and the air outlet 15 at its tip is connected to the air intake port 2. Then, the shutters 8 and 13 are opened, and the conditioned air such as cold air or warm air generated in the air conditioner 11 is transferred to the blower 12, the supply duct 14, the air outlet 15, the air intake port 2, the introduction duct 6, the air chamber 5, The air is supplied into the vehicle interior 3 through the air blowing lower, and the interior of the vehicle interior 3 is cooled and heated.

When the supply of conditioned air into the vehicle interior 3 is completed, as shown in FIG. 3, the shutter 13 is closed and the supply duct 1 is
4 can be retracted and pulled out of the vehicle limit.

Then, the shutter 8 of the vehicle 1 is also automatically closed, and conditioned air is sealed in the vehicle interior 3. The vehicle 1 then travels in this state. The above process is then repeated at the next station, and if the distance between the stations is short, the interior of the vehicle 3 is maintained in a sufficiently comfortable air-conditioned state.

Note that if the dimensions of the air outlet 15 can be changed, it can be connected to the air inlet 2 of another type of vehicle, and the supply duct 14 can also be attached to the vehicle 1. Further, the expansion and contraction of the supply duct 14 and the connection and disconnection between the air outlet 15 and the air inlet 2 may be performed manually, but they can be linked to the opening and closing of the vehicle door as passengers get on and off.

(Effects of the Invention) In the present invention, conditioned air generated by a conditioned air generator installed at a predetermined location such as a station is supplied to a track vehicle that is stopped at a predetermined stopping position via an expandable supply duct. Since the air is supplied indoors, there is no longer a need for all vehicles to be equipped with air conditioners, as was the case in the past. As a result, when there are a large number of vehicles, the cost of equipment for air conditioning is significantly reduced. Moreover, since the weight of the vehicle is reduced, vehicle operation costs such as power costs and track maintenance and inspection valves can be reduced, and the vehicle body, bogie, etc. can be simplified, thereby reducing vehicle manufacturing costs. I can do it. Furthermore, since the conditioned air generator is installed on the ground, its maintenance and inspection are easy. Furthermore, since no condensate is generated or heat is radiated into the tunnel even during cooling, it can be easily applied to subway or elevated track vehicles.
