VENTILATION SYSTEM FOR ELECTRIC TRAIN

摘要

A ventilation system for an electric train is provided to be economic without performing additional air conditioner modification and to promote ventilation automatically generated when an exit door is open. A ventilation system for an electric train includes an exit door control sensor, a ventilation device(340), and a control device. The exit door control sensor senses an open/close state of an electric train exit door(120). The control device controls so as to supply fresh air from an outside through the exit door as well as ventilate turbid air inside of the electric train by operating the ventilation device only when the exit door is open. The system further includes a CO2 sensor(230) to sense the concentration of carbon dioxide inside of the electric train. The control device controls the ventilation device to operate during the open of the exit door when the concentration of carbon dioxide is above a predetermined level.
