Title:

AIR-CONDITIONING VENTILATION SYSTEM OF HIGH-SPEED RAILROAD VEHICLE

Document Type and Number:

Japanese Patent JP2005081889

Kind Code:

A

Abstract:

To provide an air-conditioning ventilation system of a high-speed railroad vehicle using a cooling device of an air cycle system.

The air-conditioning ventilation system of the high-speed railroad vehicle is constituted such that the cooling device 12 of the air cycle system (composed of a compressor 12A, a heat exchanger 12B, and an expansion machine 12C) is installed in an air supply duct 2 communicating to the cabin of the railroad vehicle. The upstream and downstream of the cooling device 12 are connected to each other through a first bypass passage 13 which is provided with a first variable flow valve 14. The temperature of a cooling wind into the cabin is adjusted by controlling the valve 14, while pressure is in the vehicle controlled by regulating the revolving speed of an air exhaust fan 41. A dehumidifying device 11 is installed upstream of the cooling device 12, and the upstream and downstream of the dehumidifying device 11 are connected to each other through a second bypass passage 21 which is provided with a second variable flow valve 22. The humidity of the cooling wind into the cabin is adjusted by controlling the valve 22.
