PURPOSE:To decrease energy loss by effectively shutting off high pressure variation generated at passage through a tunnel and willing to be transmitted into a car, and attaining stable air supply/exhaust operations. CONSTITUTION:At least one of air supply/exhaust devices 1, 2 is of such a type air supply device as composed of a wind blower F1 incorporated in the main wind path E1 for air supply, an aux. wind path D1 connected to the discharge side of the blower, an aux. wind path throttling mechanisms SV1 installed in the aux. wind path, and a main wind path throttling mechanism EV1 installed in the main wind path at the main wind path/aux. wind path divergent part on its car side. Otherwise, it is of such a type air exhaust device as composed of a wind blower F2 incorporated in the main wind path E2 for air exhaust, an aux. wind path S2 connected to the suction side of this blower, an aux. wind path throttling mechanism SV2 installed in this aux. wind path, and a main wind path throttling mechanism SV2 installed at the main wind path/aux. wind path divergent part on its car side, wherein each throttling mechanism is made adjustable. |
