Abstract: A communication device for pipes of an air conditioner disclosed herein transmits and receives communication signals using induced electromagnetic force, generated by a signal line wound around a core assembly, thereby facilitating for coupling between the core assembly and the signal line. Also, one type of core assembly can be commonly applied to various standards of pipes. Rainwater or foreign materials cannot permeate between the signal line and the core assembly by winding the signal line on the core assembly, despite of external installation, thus preventing breakdown or degraded communication performance of the communication device. Also, with forming a signal line mounting hole through the core assembly, the signal line is fixedly inserted through the signal line mounting hole, thereby preventing in advance a movement of the core assembly even though a refrigerant pipe vibrates.

Abstract: Disclosed is an air conditioner and a control method thereof, the air conditioner where a plurality of units is connected wirelessly to receive and transmit data with each other, and the control method in which an address is set in a wireless communication method using an initially set basic channel, a group is set in response to a response signal, and communication is performed with an indoor unit belonging into the same group through a new channel. Accordingly, the plurality of units in the air conditioner is able to receive and transmit data with each other wirelessly, and a group is set with respect to multiple units so that the multiple units are able to communicate with each other directly. Additionally, because a group is able to be easily set with respected to units connected via a pipe by setting a channel, it is possible to reduce a time for setting wireless communication and make the communication setting accurate. The present disclosure allows units to communicate using a different channel according to which group each unit belongs to, thereby preventing intervention between groups and malfunction of units.
