摘要:
The present invention relates to a ventilating equipment for high speed rolling stock An object of the present invention is to regulate a change in pressure within the vehicle resulting from a change in pressure outside to avoid passengers to feel uncomfortable. The present invention is characterized in that with the change of the outside vehicle pressure some areas of the air flow passages of the air supply equipment and exhaust air equipment are adjusted. Thus the present invention proposes means for adjusting the airflow passage areas of the air supply equipment and exhaust air equipment when the pressure outside vehicle changes. The propagation of the pressure from outside into the vehicle can be regulated.

This ventilating equipment includes a low-pressure supply air blower, a high-pressure supply air blower, a low-pressure exhaust air blower, and a high-pressure exhaust air blower. This ventilating equipment ventilates car inteiror during travel of a train outside of tunnels by means of the low-pressure supply air blower and the low-pressure exhaust air blower, and also ventilates the car interior during travel in tunnels by means of the high-pressure supply air blower and the high-pressure exhaust air blower. The high-pressure supply air blower and the high-pressure exhaust air blower produce a higher discharge pressure than a changing external pressure during a-high-speed travel in tunnels.

摘要:
The present invention relates to a ventilating equipment for a vehicle. In the vehicles in recent years, the space allowed to dispose equipments for the vehicle is subjected to a tendency of being limited since the comfort of the vehicle has been improved. Therefore, the size of ventilating equipments has been required to be reduced. The present invention is characterized by that a supply-air equipment (20) and an exhaust-air equipment (30) are connected to one driving device (11) for the purpose of reducing the overall size of the equipment and thereby minimizing the space in which this equipment is located. Furthermore, the driving device of the equipment structured as described above is arranged to be effectively cooled by utilizing air to be supplied or air to be exhausted.
