断面寸法の増大を防止する試みがなされている。Conventionally, air-conditioning systems for railway vehicles have installed a centralized unit on the roof, installed a cold air duct in the center longitudinal direction of the cabin ceiling, and provided return ports for circulating air on both sides of the cold air duct at the bottom of the unit. So-called roof-mounted central cooling systems were common. However, in the case of a cooling system with this type of configuration, since the cooling system is centrally installed only on the roof of the car, the cross-sectional dimensions of the car become large, and especially in the case of subway cars, there is an increase in tunnel construction costs and This had the disadvantage of increasing running resistance. Therefore, in the case of subway cars, an attempt was made to prevent an increase in the cross-sectional dimensions of the car by installing a so-called separate type cooling system, in which a condenser unit is placed under the floor and an evaporator unit is placed between the ceiling and the roof. is being done.
しかし、この場合でも、ェバポレータュニットを設置す

In addition, the roof-mounted central air-conditioning system, which is attached to a passenger compartment, supplies cold air unevenly from the center in the front and rear directions, resulting in uneven temperature distribution in the passenger compartment.

面である。Next, the operation of the evaporator units 3, 3' will be briefly explained. The air in the passenger compartment 17 is sucked in through the return filter 1, and is combined with fresh outside air sucked in through the fresh air filter 12 provided in a part of the gable 5, passes through the cooler 6, and is cooled here. cool air ducts 15, 15 by the fan 10 through the suction duct 19.
', and is discharged from the discharge port 16 into the passenger compartment 17.
According to one embodiment of the present invention, as shown in FIG. The air cooled by the evaporator units 3 and 3' is distributed to the left and right side walls 4 and 5 of the vehicle 1 and the ceiling plate 9.
Since the air is blown into the passenger compartment 17 from the outlet 16 through the cold air ducts 15 and 15' installed near the corner where the There is an advantage in that the temperature distribution within 17 can be made uniform. In other words, since there is no cold air duct under the ceiling above the central aisle of guest room 17,
The interior space is wider, so standing passengers won't feel cramped. In addition, it is only necessary to directly connect the evaporator units 3, 3' installed diagonally on the left and right sides of the front and rear end walls of the vehicle 1 to the cold air ducts 15, 15' installed on the same side, respectively. This eliminates the need for a communication duct and simplifies the structure of the cold air duct. Moreover, the cold air duct 15,
The temperature of the air blown out from the outlet 16 of the evaporator unit 3, 3' is lower as it approaches the Evaporator unit 3, 3', and increases as the distance increases, but this is because the cold air ducts 15 and 15' are oriented in opposite directions. , the high temperature of one is compensated for by the low temperature of the other, and the temperature in the passenger compartment 17 becomes uniform. Furthermore, there is no need to particularly increase the cross-sectional dimensions of the vehicle in order to accommodate the cooling device. FIGS. 4 and 5 are drawings corresponding to FIGS. 2 and 3, respectively, showing other embodiments of the present invention.

じを与えることがないとし、う効果がある。The difference between FIG. 4 and FIG. 2 is that in FIG. 4, the condenser unit 2, 2' is not installed under the floor of the vehicle 1, but is installed on the end wall. That is, as shown in FIG. 5, a compressor 20, a condenser 21, and a fan 23 driven by a motor 22 are installed in the gable wall composed of the inner gable 4 and the outer gable 5 in that order from below. After the compressor 20 and the condenser 21 are cooled, the outside air is sucked in through the outside air filter 24 provided below the gable 5, and then discharged from the scale opening 25 provided above the gable 5. I made it. According to the embodiment shown in FIGS. 4 and 5, by installing the condensers 2 and 2' in the gable wall, the space under the floor can be used for reinstalling other equipment, and furthermore, Since the distances between the condenser units 2, 2' and the evaporator units 3, 3' are shortened, the piping of the cooling system is simplified. If the vehicle does not have through passages 18, 18', the capacitor units 2, 2' and the evaporator units 3, 3' can be installed in the end wall. makes piping even easier. As explained above, according to the present invention, it is possible to equip a cooling device without reducing the cabin space inside the car and without increasing the cross-sectional dimensions of the car, and furthermore, it is possible to make the temperature distribution in the cabin uniform. Moreover, it is effective because it does not make standing passengers feel cramped.
