[0002]

2. Description of the Related Art In recent years, as an air conditioner for offices, a system that can cope with a partial load by supplying air from an air conditioner under the floor and blowing air into the room using a plurality of floor blowing units has become widespread. .

Conventionally, this type of floor blowing unit is generally shown in FIG. The configuration is described below with reference to FIG.
This will be described with reference to FIG.

As shown in the figure, a floor blowing unit 101
Is a fan motor 10 for blowing conditioned air into a room.
2, an air volume switching unit 103 for setting the air volume of the fan motor 102, a hand operation unit 104 for issuing an air volume switching command to the air volume switching unit 103 from a hand, and a communication unit 105 for transmitting a command from a distance. It had been.

In the above configuration, the hand operation device 104 switches and stops the supply air volume and switches to the automatic mode, and the communication means 105 transmits the air volume setting symbol 107 and the forced stop command 108 from the remote operation device 106 to the air volume switching device. 103. In the air volume switching unit 103, the forced stop command 108 is given top priority, and the air volume set by the hand controller 104 or the air volume transmitted from the communication unit 105 in the automatic mode is set as the set air volume.
Will be started and stopped.

[0006]

In such a conventional floor blowout unit 101, when performing automatic control, the air volume setting symbol 107 and the forced stop command 108 from the remote controller 106 are set to all-in-one batch command or individually. In the former case, it is not possible to cope with the load balance of each zone, and in the latter case, there is a problem with the complexity of assigning the airflow settings to each unit. Was.

Further, a forced stop command 1 from the remote controller 106
At the time of return after the stop after receiving 08, the operation is restarted from a stopped state or a specific set state, and there is a problem that an optimum operating state cannot be obtained unless the operation device 104 is operated.

Further, when the air volume is switched by the hand operation device 104, there is a problem that even if the room temperature greatly deviates from the set value, the remote operation device 106 cannot perform automatic control.

There is also a problem that the vehicle is stopped when the power is turned off and the operation is not performed unless the operation device 104 is operated.

A first object of the present invention is to solve the above-mentioned problem and to easily set an air volume for each zone in automatic control of a floor blowing unit.

A second object is to make it possible to return to the operating state before the forced stop when returning from the forced stop.
