(57) [Summary] [Problem] To reduce discomfort to passengers. An air duct connecting inside and outside of a vehicle is provided.
The gradient of the pressure fluctuation of the air that can flow through
When the gradient is equal to or higher than the set value, dampers 6 and 7 reduce both the flow path resistance of duct 2 that takes in air outside the vehicle and the flow path resistance of duct 4 that discharges air inside the vehicle. . According to this, since the flow path resistance of the ducts 2 and 4 connecting the inside and the outside of the vehicle is reduced due to the pressure fluctuation gradient, the gradient of the pressure fluctuation inside the vehicle does not become large and the passengers inside the vehicle feel discomfort. Does not occur.

る。2. Description of the Related Art In a vehicle, that is, a railway vehicle, when passing through a tunnel at a high speed, a sudden pressure change occurs between the vehicle and the tunnel. Therefore, there has been a problem that the pressure fluctuation is transmitted to the vehicle and gives a passenger discomfort. In order to solve this problem, air outside the vehicle is taken into the vehicle by an air supply device and an exhaust device using a blower having a characteristic that the amount of change in the air volume is small with respect to the ratio of the pressure change outside the vehicle. A ventilator for discharging air is known. A related device of this type is, for example, Japanese Utility Model Publication No. 53-28166.

It is not possible to cope with it. That is, the discomfort given to the passengers in the vehicle is determined by the absolute value of the vehicle interior pressure and the gradient of the fluctuation of the vehicle interior pressure.

させる。The operation of the above configuration will be described. When the vehicle travels at a high speed and enters the tunnel and the external pressure Pout changes as shown in FIG. 3, the external pressure detector 5 detects the external pressure that changes every moment, and the detection result is determined by the controller. 8 is input as a control input.
The controller 8 calculates the fluctuation gradient dp / dt due to the pressure fluctuation and the absolute value Px of the pressure fluctuation by liquidating the detection result. Then, the fluctuation gradient dp / dt and the absolute value P
The blower characteristics and the resistance characteristics of the supply-side damper 6 and the exhaust-side damper 7 corresponding to Table 1 below are selected.
The control command corresponding to each selected characteristic is supplied to the air supply device 1,
The output is output to the exhaust device 3, the supply-side damper 6, and the exhaust-side damper 7 to control the operation. Pressure fluctuation gradient dp / d
t (mm / Aq) is set to 10, 20, 30, and 40, and the supply-side damper 6 and the exhaust-side damper 7 are provided with flow path resistances R 1 , R 2 , R corresponding to the fluctuation gradient dp / dt. Control to 3 . The flow path resistance R is reduced as the fluctuation gradient dp / dt increases. The absolute value of pressure Px (mmAq) is 10
The set values are 0, 200, 300, and 400, and the air supply device 1 and the exhaust device 3 are controlled to the blowing characteristics P 3 -Q 3 , P 2 -Q 2 , and P 1 -Q 1 corresponding to the absolute value Px. I do. As the absolute value Px of the pressure increases, the blowing characteristics PQ are improved.

From Table 1, the blowing characteristics P 1 -Q of the blower are shown. 1, and and the resistance characteristics of the supply air damper 6 and the exhaust-side damper 7 controller 8 supply device a control command to R 3 1, exhaust system 3, the supply air damper 6 and the exhaust-side damper 7 give.

量変化の割合は小さい。As a result, the air supply characteristics of the air supply device 1 and the exhaust device 3 are improved, so that a change in air volume with respect to a change in the pressure outside the vehicle is reduced, and a change in the pressure inside the vehicle can be suppressed. For example, in FIG. 2, the change in the air volume when the pressure P is changed from the pressure Pa in the characteristic P 2 -Q 2 to the pressure Pb is changed from the air volume Qa 2 to the air volume Qb 2 ,
1 air volume change when what was the pressure Pa is changed into a pressure Pb in -Q 1 is air volume Qb 1 from the air volume Qa 1, the ratio of the air volume change is small.

変動に対する影響を減少させることができる。Meanwhile, the supply air damper 6 and the exhaust-side damper 7, to minimize the flow resistance as the most open state in resistance characteristic R 3. Thereby, the amount of air blown from the air supply device 1 and the exhaust device 3 is increased to the maximum. Therefore, even if the outside pressure fluctuation fluctuates rapidly, the amount of air supplied and exhausted increases, so that the rate of increase / decrease in the air flow due to the pressure fluctuation decreases, and the influence on the inside pressure fluctuation is reduced. Can be reduced.

Aq / sec. ), And when the absolute value Px of the pressure fluctuation is larger than the maximum limit value (set value: 400) (when it exceeds), the supply-side damper 6 and the exhaust-side damper, respectively. Close 7 As a result, fluctuations in the external pressure are mechanically shut off.

である。As described above, since the duct connecting the inside of the vehicle and the outside of the vehicle is closed by the pressure fluctuation gradient, the gradient of the pressure fluctuation inside the vehicle does not become large and the passengers inside the vehicle do not feel uncomfortable. . Further, since the pressure is obtained and the duct is closed when the absolute value of the pressure is equal to or greater than the set value, the passengers in the vehicle do not feel uncomfortable even in this case.

Does not occur, and in order to recover in a short time, even if the air flow path is shut off as described above,

While ventilating to the maximum limit value, the effect of pressure fluctuations outside the vehicle can be suppressed, and fluctuations in the pressure inside the vehicle can be reduced. Therefore, problems such as insufficient ventilation do not occur.
