Benefits of technology
The present invention aims to prevent signal interference between different frequency bands during communication between an outdoor unit, indoor unit, or central controller. This improves safety and efficiency of the system. Additionally, the outdoor unit or indoor unit can communicate with the central controller using wireless or dedicated line methods, depending on the installation environment, to enhance system operation.
Problems solved by technology
However, when a transfer path (line) such as the same pipe or the dedicated line is used as a transfer path for communication between the indoor unit 100 and the outdoor unit 200 and communication between the central controller 300 and the outdoor unit 200, signal interference may be caused between signals transferred along the transfer path.

The air conditioner includes indoor units, at least one outdoor unit connected to the indoor units via a refrigerant pipe to drive the indoor unit using a first signal, a central controller to control operations of the outdoor unit and the indoor units using a second signal, the second signal having a frequency band spaced from that of the first signal, and a communication apparatus installed in the outdoor unit or one of the indoor units connected to the outdoor unit to communicate with the central controller using the second signal, whereby signals with different frequency bands can be used upon communication between the outdoor unit and the indoor unit and communication between the outdoor unit or indoor unit and the central controller, so as to reduce signal interference and enhance efficiency of a system operation, resulting in improving safety of the system.
Description
TECHNICAL FIELD[0001]The present disclosure relates to an air conditioner, and more particularly, an air conditioner having an outdoor unit or an indoor unit capable of performing communications with a central controller using a plurality of communication methods, and a communication apparatus and method thereof.BACKGROUND ART[0002]In general, an air conditioner, as shown in FIG. 1, includes an outdoor unit 200 to control distribution and circulation of a refrigerant, an indoor unit 100 connected to the outdoor unit to supply air into each indoor, and a central controller 300 connected to the outdoor unit 200 for center control of operations of the air conditioner.[0003]The central controller 300 is provided, by a user's registration, with network information and setting information relating to the air conditioner, such as device information on the indoor unit 100 and the outdoor unit 200. The central controller 300 includes a control program capable of individually controlling each...
