Abstract

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.
