Abstract: Disclosed is an air conditioner including a plurality of units having an outdoor unit and an indoor unit. The plurality of units includes a controller configured to control an input/output and control to operate according to setting and a communication unit configured to transmit and receive data in a wireless communication method between the plurality of units. The communication unit includes a plurality of antenna connection units respectively connected to the plurality of antennas, and a transmission/reception unit configured to apply a signal of a certain frequency band to the plurality of antennas through the plurality of antenna connection units, and to process a signal received from the plurality of antennas. The communication unit includes a plurality of antennas, and is configured to transmit and receive data through multiple input and output, so that the plurality of units can directly communicate wirelessly, specify a frequency of a signal used in consideration of obstacles in a building and installation distances, and perform multiple input and output by using the plurality of antennas, thereby achieving stable communication by securing communication coverage, and improving efficiency and stability according to the management and operation of the air conditioner.

Abstract: Disclosed is a control method of an air conditioner system including: when a preset reception rate degradation error occurs in one or more indoor unit, transmitting a channel switch request signal to an outdoor unit belonging to the particular group; performing a channel scan by each of the outdoor unit and the plurality of indoor units; transmitting, by the plurality of indoor units, channel scan results to the outdoor unit; determining, by the outdoor unit, a channel for use of the particular group based on a result of a channel scan performed by the outdoor unit and the channel scan results received from the plurality of indoor units; and outputting, by the outdoor unit, information on the determined channel to the plurality of indoor units. Accordingly, it is possible to change to a good communication channel according to change in a communication environment.
