BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor blower fan unit for air-conditioning a building or the like.

[0002]

2. Description of the Related Art In recent years, floor-blowing fan units for blowing air conditioned by an air conditioner under a floor in a room to blow air into the room have been widely used in buildings and the like.

Conventionally, this type of floor blower fan unit is generally shown in FIG. Hereinafter, the configuration will be described with reference to FIG.

[0004] As shown in the figure, an air conditioner 101 for performing air conditioning in a room and an air conditioner for monitoring a measurement value of a supply air static pressure measuring means 102 and adjusting a supply air volume of the air conditioner 101 are shown. Controller 103 and room temperature measuring means 104
From the indoor temperature control means 105 for monitoring the measured values of the air flow, the start / stop signal line 106, the strong air flow signal line 107, and the medium air flow signal line 10
8. Pull out the weak air flow signal line 109 and set the floor blowing unit 1
It was connected to the air volume switching means 112 for adjusting the rotation of the ten air supply fans 111.

In the above configuration, the room temperature measuring means 104
The difference between the measured value and the set value of the
5, when the signal is input to the floor blowing fan unit 110 by the start / stop signal line 106, the air flow signal line 107, the air flow signal line 108, and the air flow low signal line 109, the rotation speed of the air supply fan 111 is changed by the air flow switching means 112, The air supply air volume changes, and this change causes a change in the measurement value of the air supply static pressure measuring means 102. The controller 103 of the air conditioner adjusts the air volume of the air conditioner 101 in response to the change. Due to the interaction with the fan unit 110,

[0006]

In such a conventional floor blower fan unit 110, the start / stop signal line 106, the airflow signal line 107, the airflow middle signal line 108, and the airflow weak signal line 1 are provided.
09 must be separately wired from the indoor temperature control means 105. If there are a plurality of floor blower fan units 110, the number of wires is large at the time of construction and at the time of changing the partition, so that large wiring including prevention of incorrect wiring is required. There was a problem that wiring work was required.

Further, since the controller 103 of the air conditioner for controlling the air conditioner 101 for controlling the air conditioning of the room and the room temperature control means 105 for controlling the floor blower fan unit 110 are separately provided, an efficient room is provided. There is a problem that air conditioning cannot be performed.

In order to adjust the amount of air sent into the room, the change in the air flow of the floor blower fan unit 110 depends only on the supply air static pressure measuring means 102 to determine the air flow of the air conditioner 101. In addition, for the operation state of the floor blower fan unit 110, the amount of air blown from the air conditioner 101 is not properly obtained, or the air supply static pressure measuring means 102 is installed to obtain an appropriate air supply static pressure. There was a problem that the surrounding conditions needed to be considered when selecting the position.

A first object of the present invention is to provide a floor blower fan unit which can simplify wiring work when constructing the floor blower fan unit and changing partitions. And

A second object of the present invention is to perform efficient air conditioning by simultaneously controlling a floor blowing fan unit by a controller of the air conditioner for controlling the air conditioner.

A third object is to transmit the operating state of the floor blower fan unit to the controller of the air conditioner by communication means so that the air blower can obtain an appropriate air volume from the air conditioner. is there.

[0012]

In order to achieve the first object, a floor blower fan unit according to the present invention has a first means for supplying air sent from an air conditioner for air-conditioning the room into the room. A configuration including a fan, air volume switching means for switching the supply air volume, and communication means for starting and stopping the air conditioner and switching the air volume of the fan unit by communication from the indoor temperature adjustment means for adjusting the indoor temperature. It is.

Further, in order to achieve the second object, a second
Means, an air supply fan that sends air sent from an air conditioner that air-conditions the room into the room, an air volume switching unit that switches the supply air volume, and communication from a controller of the air conditioner that controls the air conditioner. And a communication means for starting and stopping the air conditioner and switching the air volume.

Further, a third means for achieving the third object is an air supply fan for feeding air into the room, an air volume switching means for switching the supplied air volume, and communicating the current air supply volume by communication. The air conditioner controller adjusts the amount of air to be transmitted to the controller of the air conditioner, and the air conditioner controller adjusts the amount of air to be sent from the air conditioner. It is configured.

[0015]

According to the first aspect of the present invention, starting and stopping and switching of the air volume can be performed using the communication means only by wiring the communication line from the indoor temperature adjusting means to the plurality of floor blowing fan units. This makes it possible to greatly simplify wiring work at the time of construction and at the time of changing partitions.
