Summary:PURPOSE: A ventilation system at subway station, which is based on the comparison between inside air and outside air and prevents from freezing in the winder or corrosion by washing is provided. CONSTITUTION: A ventilation system at subway station, which is based on the comparison between inside air and outside air comprises a pollution sensing device (10), air pressure controlling device (20), controller (30), air supplying device (40), and air exhausting device (50). The pollution sensing device senses the pollution degree of inside air or outside air at the subway station and transfers pollution information to the air pressure controlling device. The air pressure controlling device sets pressure inside the subway station using the pollution information. The controller operates the air supplying device or air exhausting device.
