Title:

VENTILATOR FOR ROLLING STOCK AND OPERATING METHOD THEREOF

Document Type and Number:

Japanese Patent JPH04212669

Kind Code:

A

Abstract:

PURPOSE: To ventilate a rolling stock continuously without increasing the extent of power consumption as well as without giving any uncomfortable feeling to passengers even if the rolling stock runs at high speed.

CONSTITUTION: This ventilator is provided with a low-pressure supply ventilating fan 1, a low-pressure exhaust fan 4, a high-pressure supply ventilating fan 7, and a high-pressure exhaust fan 8, and it is made up of setting up each of cutoff valves 2, 5 in each air passage of these fans 1 and 4, through which a controller 11 closes the said cutoff valve during rolling stock's travel in a tunnel according to output of a running state detector 10 detecting the running state of a rolling stock. With this operation, since the said high-pressure supply- exhaust fans are high in discharge pressure, any effect to passengers due to external pressure fluctuations during the vehicle travel in the tunnel is prevented, thus ventilation can be done in succession.
