Description

  The present invention relates to an air conditioning system that can arbitrarily change an address set in an indoor unit as necessary, and an address setting method thereof.

Conventionally, in a building or factory air conditioning system, an air conditioning system in which a plurality of indoor units are connected to one or a plurality of outdoor units is known. An individual address is set for each indoor unit in order to transmit data between the outdoor unit and the indoor unit. This address setting is usually performed by an operator after the installation is completed.
There are three types of address setting methods: remote control address setting, automatic address setting, and manual address setting. In the remote control address setting, the worker sets the address of each indoor unit with the remote control. In the automatic address setting, the address of each indoor unit is automatically set by program processing. In manual address setting, an operator manually sets the address of each indoor unit using a switch on the board.
Patent Document 1 discloses an address setting method in which an address setting order is determined by performing communication between a plurality of indoor units, and then an address of each indoor unit is set by a remote controller.
Japanese Patent Laid-Open No. 11-83130

However, in the above remote control address setting, since the address is not determined in the initial state after product shipment, the target to set the address from the remote control cannot be specified, and when one remote control is connected to one indoor unit There was a restriction that only can be set. Further, in the automatic address setting, the address of each indoor unit is automatically set by program processing or the like, and thus the address cannot be set or changed to a desired address. In the manual address setting, since the switch is arranged on the board of the indoor unit controller, it is necessary to perform work on the ceiling or the like, and there is a problem in workability.
Further, in the address setting method disclosed in Patent Document 1, an operation from a remote controller is always required to set an address, and the work burden on the worker is large. Furthermore, once an address is set, only a specific address cannot be arbitrarily changed.

Below, one embodiment of an air-conditioning system and its address setting method concerning the present invention is described with reference to drawings.
FIG. 1 is a block diagram showing a schematic configuration of an air conditioning system according to an embodiment of the present invention.
As shown in FIG. 1, the air conditioning system 1 according to the present embodiment includes an outdoor unit 2, a plurality of indoor units 3a to 3f, and a plurality of remote controllers (remote control means) 4a to 4c. Yes. The outdoor unit 2 and the indoor units 3a to 3f are connected by a common refrigerant system. Furthermore, the outdoor unit 2 and the indoor units 3a to 3f are connected by a communication line 10 and can communicate with each other. The remote controller 4a is provided in common corresponding to the indoor units 3a to 3d, and the remote controllers 4b and 4c are provided corresponding to the indoor units 3e and 3f, respectively. The remote controller 4a is connected to the indoor units 3a to 3d via the communication line 20a, and the remote controllers 4b and 4c are connected to the indoor units 3e and 3f via the communication lines 20b and 20c, respectively. Each of the remote controllers 4a to 4c has a configuration capable of transmitting driving instruction information to the corresponding indoor units 3a to 3f.

FIG. 2 is a block diagram showing a schematic configuration of the remote controllers 4a to 4c.
The remote controllers 4 a to 4 c include a communication unit (transmission unit) 11, an input unit 12, a display unit (display unit) 13, and a control unit 14.
The communication unit 11 transmits and receives information to and from the corresponding indoor units 3a to 3f. The input unit 12 notifies the control unit 14 of various types of information such as address setting information input by the user and operation mode switching. The display unit 13 displays the addresses of the indoor units 3a to 3f received by the communication unit 11, information related to the operation of the indoor units 3a to 3f, and the like. The control unit 14 controls the communication unit 11, the input unit 12, and the display unit 13.

Next, an address setting method of the air conditioning system 1 having the above configuration will be described with reference to a flowchart shown in FIG.
First, when the installation of the outdoor unit 2 and the indoor units 3a to 3f and the wiring work are completed, the user turns on the power of the air conditioning system 1 (S1). When the indoor units 3a to 3f are powered on, the addresses of the indoor units 3a to 3f are automatically set by program processing (S2). Once the addresses are automatically set in the indoor units 3a to 3f, the set addresses are transmitted to the corresponding remote controllers 4a to 4c, respectively.

  When the automatically set addresses are received by the communication units 11 of the remote controllers 4a to 4c, the addresses are displayed on the display unit 13 of the remote controllers 4a to 4c. Specifically, the addresses of the indoor units 3a to 3d are displayed on the display unit 13 of the remote control 4a, the addresses of the indoor units 3e are displayed on the display unit 13 of the remote control 4b, and the display unit 13 of the remote control 4c is displayed. The address of the indoor unit 3f is displayed. Here, regarding the remote controllers 4b and 4c in which the remote controller and the indoor unit are in one-to-one correspondence, it is possible to grasp which indoor unit corresponds to the address displayed on the display unit 13, but a plurality of indoor units 3a. As for the remote controller 4a corresponding to .about.3d, at this time, among the four addresses of the indoor units 3a to 3d received by the remote controller 4a, any address corresponds to any of the indoor units 3a to 3d. It is not possible to identify. For this reason, the user confirms the address of the remote controller 4a (S3). The confirmation of this address is performed by transmitting any address displayed on the remote controller 4a and driving instruction information for the indoor units 3a to 3d corresponding to the address.

For example, when four addresses displayed on the display unit 13 of the remote controller 4a are designated by the user via the input unit 12 and further when driving instruction information is input, the address of the designated address is displayed. Driving instruction information is transmitted to the indoor unit. The indoor unit that has received the operation instruction information drives the fan motor and starts operation. By confirming this driving operation, for example, the rotation of the fan, the user can confirm that what is displayed on the remote controller 4a is the address of the indoor unit where the driving operation is started.
By performing the above operation for all addresses displayed on the remote controller 4a, the correspondence between the addresses and the indoor units 3a to 3d corresponding to the remote controller 4a is confirmed.
In this embodiment, the address is confirmed by the rotation of the fan. Instead, a louver, a pilot lamp, an alarm buzzer, or the like may be used.

After confirming the address, when the user desires to change the address set in the indoor units 3a to 3d, the user instructs the mode switching by operating the input unit 12 of the remote controller 4a. Thereby, the control unit 14 switches from the operation instruction mode instructing the operation to the indoor units 3a to 3d to the address change mode for changing the address (S4). Subsequently, the user selects the address of the indoor unit to be changed, for example, the indoor unit 3a, via the input unit 12 (S5) and inputs a new address to be set in the indoor unit 3a ( S6) The new input address is transmitted to the indoor unit 3a via the communication unit 11 of the remote controller 4a. When the indoor unit 3a receives a new address, the indoor unit 3a changes the currently set address to a new address.
When a plurality of outdoor units are provided, the address of the outdoor unit is transmitted in addition to the new address when the address is changed. By transmitting the address of the outdoor unit, it is also possible to change the address of the outdoor unit that is recognized as being connected to the indoor unit.

Subsequently, when there is another address to be changed (S7), the user repeatedly performs an operation for selecting the address of the indoor unit to be changed. As a result, the address is changed in the same procedure as described above. When the user has finished changing all the addresses that he / she wants to change, he / she performs an address change work end operation via the input unit 12 of the remote controller 4a (S8). As a result, the remote control 4a is switched from the address change mode to the driving instruction mode, and the address setting operation is completed (S9).
Similarly to the above, when the user desires to change the addresses of the indoor units 3e and 3f in the remote controllers 4b and 4c, the user can change the addresses of the indoor units 3e and 3f by performing the above operation.

  As described above, according to the air conditioning system and the address setting method thereof according to an embodiment of the present invention, the ceiling on which the indoor unit is installed by the automatic address setting of the indoor unit and the address changing operation with the remote controller. Since the address setting work on the back or the like is not necessary, the work efficiency is improved. In addition, among the automatically set addresses, the address that you want to change can be changed by the remote control as necessary, so you can concentrate the addresses that have the number of each room where the indoor unit is installed at the head. An address suitable for management can be set.

  As mentioned above, although embodiment of this invention was explained in full detail with reference to drawings, the specific structure is not restricted to this embodiment, The design change etc. of the range which does not deviate from the summary of this invention are included.

In the above embodiment, it is assumed that six indoor units 3a to 3f are connected to the outdoor unit 2, but the number of indoor units that can be connected to each outdoor unit is set according to the performance of the outdoor unit. Therefore, the number of indoor units is not limited as long as it is within the range. Moreover, the structure by which multiple outdoor units are provided may be sufficient.
In the above embodiment, the remote controller is connected to the indoor unit by wire as an example. However, the remote controller may be connected wirelessly.
