An air conditioning fan control unit 37 that controls the drive of the fan 24 is provided.

The control device 30A acquires the train passing time information of the subway station where the private room booth 1C is installed via the network NW (S201). The train passing time can be acquired based on the current operation information including the timetable information and the delay information. Then, when the predetermined time is earlier than the acquired train passing time (S202: Yes), the pressurizing / depressurizing fan 24 is pressurized (S203). Specifically, as shown in FIG. 14, the pressurizing / depressurizing fan 24 is driven to suck the air in the concourse space into the private room booth 1C to pressurize the space in the private room booth 1C. As a result, it is possible to suppress the destruction of the air curtain by the train wind W1 when the train T enters the platform space 100 from the tunnel space 120 on the left side, and to form an air harmony space in the private room booth 1C.

Next, when the departure time of the train T arrives (S204: Yes), the pressurizing / depressurizing fan 24 is decompressed (S205). Specifically, as shown in FIG. 15, the pressurizing / depressurizing fan 24 driven in the intake mode is switched to the exhaust mode to bring the space of the private room booth 1C into a negative pressure state. As a result, it is possible to suppress the destruction of the air curtain by the train wind W2 when the train T leaves the platform 110 toward the tunnel space 130 on the right side, and maintain the air-conditioned space formed in the private room booth 1C. When a predetermined time has elapsed from the departure time (S206: Yes), the operation of the pressurizing / depressurizing fan 24 is stopped (S207). As a result, the private room booth 1C is in a state where air circulation is formed by the intake fan 22, the exhaust fan 23, and the air conditioner 13.

"Modification example"
FIG. 16 is a flowchart showing the operation flow of the air conditioning system according to the modified example. The air conditioning system operates the pressurizing / depressurizing fan 24 based on the wind speed information of the anemometer 160 installed in the platform space 100 and the concourse space 140 to suppress the destruction of the air curtain by the train winds W1 and W2.

The wind speed detection information of the wind direction anemometer 160 installed in the platform space 100 and the concourse space 140 where the private room booth 1C is installed is acquired via the wind speed detection unit 36 of the control device 30A (S301). Then, it is determined whether or not the wind speed V of the acquired anemometer 160 is larger than the predetermined wind speed threshold value Vth (S302). In step 302, the control device 30A detects that the train T enters the platform space 100 from the tunnel space 120 on the left side.

When the wind speed V is larger than the predetermined wind speed threshold value Vth (S302: Yes), the pressurizing / depressurizing fan 24 is pressurized (S303). Specifically, the pressurizing / depressurizing fan 24 is driven to suck the air in the concourse space into the private room booth 1C to pressurize the space in the private room booth 1C (see FIG. 14). As a result, it is possible to suppress the destruction of the air curtain by the train wind W1 when the train T enters the platform space 100 from the tunnel space 120 on the left side, and to form an air harmony space in the private room booth 1C.

Next, it is determined whether or not the wind speed V is smaller than the predetermined wind speed threshold value Vth (S304). The control device 30A will detect in step 304 whether the train T has left the platform 110 toward the tunnel space 130 on the right side. When the wind speed V is smaller than the predetermined wind speed threshold value Vth (S304: Yes), the operation of the pressurizing / depressurizing fan 24 is stopped (S305). After that, the private room booth 1C is in a state where air circulation is formed by the intake fan 22, the exhaust fan 23, and the air conditioner 13.
