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 translation: 本文公开的空调机的管道的通信装置使用由缠绕在芯组件上的信号线产生的感应电磁力来传送和接收通信信号，从而有助于芯组件和信号线之间的耦合。 此外，一种类型的芯组件可以通常应用于各种管道标准。 尽管有外部安装，但是通过将信号线缠绕在芯组件上，雨水或异物不能在信号线和芯组件之间渗透，从而防止通信设备的故障或通信性能下降。 此外，通过形成通过芯组件的信号线安装孔，信号线固定地插入信号线安装孔，从而即使制冷剂管振动也预先防止芯组件的移动。

Abstract: Disclosed is an air conditioner. An air conditioner includes: a plurality of units including an outdoor unit and an indoor unit, and distributed at a plurality of layers in a building; and a control unit configured to monitor and control the plurality of units, wherein the control unit and the plurality of units include a communication unit configured to transmit/receive data in a wireless communication unit, respectively, and the communication unit transmits/receive the data using a sub-giga band frequency. A plurality of units transmit/receive data in a wireless communication scheme so that an indoor unit and an indoor unit, and an indoor unit and an outdoor unit may directly communicate with each other in a wireless scheme, and the indoor unit may directly communicate with a control unit without through the outdoor unit. Since a separate communication line is not installed, installation and operation costs may be reduced. Communication may be stably performed in a high-rise building and may be performed regardless of obstacles by specifying a frequency of a signal used by taking into consideration obstacles and an installation in a building. Direct communication between units is possible so that effects in management and operation of the air conditioner are increased to improve the stability.

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. In addition, 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.
