PROBLEM TO BE SOLVED: To decrease the mixture of air and efficiently condition air in a platform by providing blowers for isolating air on the track of vehicles facing the platform of a subway station from air in a tunnel extending from the station. SOLUTION: Air conditioner 3 are buried on the wall surfaces of the platform 2 of a subway station 1. Upper blowers 6 and lower blowers 7 are provided on the line side of the platform 2 and two fans 6a, 6b and 7a, 7b are respectively provided in right and left sides. Air from the inner fan 6a is guided to the inlet port 8a of the inner fan 7a, and air from the outer fan 6b is guided to the inlet port 8b of the outer fan 7b, so that the air curtains 23 and 24 of two layers are formed. Air C on the platform 2 and air A on a track are partitioned by the air curtains 23 and 24, and the air A on the track and air in a tunnel are partitioned by another air curtain. Accordingly, other air hardly flows into the platform. |
