The configuration of the air supply / exhaust member 150 with a fan is not particularly limited as long as the opening / closing and the wind direction / volume can be adjusted between the upper side and the lower side of the lid member 154, that is, between the upper side and the lower side of the personal air outlet 140.

Further, the air supply / exhaust member 150 with a fan may be connected to the communication network by a crossover wiring as shown in FIG. Hereinafter, the description of the contents overlapping with the contents described with reference to FIGS. 6 to 8 in the configurations shown in FIGS. 11 to 13 will be omitted. In the configuration shown in FIG. 11, the control unit 450 is connected to the communication hub 460 by a communication cable 404 such as a LAN (Local Area Network) cable.

In the configurations shown in FIGS. 11 and 12, since a plurality of control units 450 are connected to the communication hub 460 by crossover wiring by a communication cable 404 or the like, the number of wirings of the fan-equipped air supply / exhaust member 150 can be reduced. For example, a commercially available one-touch connector or the like can be applied to the power supply line 409. For example, a modular cable compatible with CAT5e can be applied to the communication cable 404.

In the configuration shown in FIGS. 11 and 12, a router 480 is connected to at least a part of the control units 450 among the plurality of control units 450 in place of the fan-equipped air supply / exhaust member 150. The router 480 can receive the wireless signal from the mobile terminal 300. The operation content of the operation screen displayed on the operation screen illustrated in FIG. 5 on the mobile terminal 300 is received by the router 480. The signal regarding the operation content received by the router 480 is input to the control unit 450 to which the air supply / exhaust member 150 with a fan is connected via the control unit 450 and the communication cable 406. Therefore, the user switches between the weak mode and the strong mode of the air supply / exhaust member 150 with a fan, and adjusts the wind direction and volume from the mobile terminal 300 via the router 480, the control unit 450, and the communication cable 406. Can be done.

On the other hand, in the configurations shown in FIGS. 11 and 12, for example, the status of the fan-equipped air supply / exhaust member 150 can be acquired from a remote PC in the management room or monitoring room through the communication network, and the wind direction and air volume of the fan-equipped air supply / exhaust member 150 can be obtained. You can remotely control the set values of. In the air conditioning system 50, in addition to controlling the wind direction and the air volume, an alarm signal can be output from the control unit 450 to which the corresponding fan 160 is connected when the fan 160 fails. For example, the alarm signal described above is output when the rotation speed of the fan 160 is 500 rpm or less for 10 seconds or longer. In a remote control room or monitoring room, it is possible to monitor whether or not an alarm signal is output.

As shown in FIG. 13, a plurality of fan-equipped air supply / exhaust members 150, a control unit 450, and a router 480 (not shown in FIG. 13) are arranged in the underfloor space 130. The communication hub 460 is arranged in, for example, the ventilation space 170. Of the plurality of control units 450 (three in FIG. 13), adjacent control units 450 are connected by individual communication cables 404. Of the plurality of control units 450, the control unit 450 located closest to the side space 120 is directly connected to the communication hub 460 via the communication cable 404. The communication specifications are, for example, TCP / IP. In the configurations shown in FIGS. 11 to 13, since the plurality of control units 450 are connected by crossover wiring by communication cables 404, 406, etc., the number of wirings of the fan-equipped air supply / exhaust member 150 can be reduced. Further, in the configurations shown in FIGS. 11 to 13, a communication master unit such as a personal computer (PC) is not used between the control unit 450 that controls the operation of the air supply / exhaust member 150 with a fan and the communication network 500. , Only the communication hub 460 is provided. Therefore, the connection system between the air supply / exhaust member 150 with a fan and the communication network 500 can be easily configured.
