Abstract: Disclosed is an air conditioner system comprising at least one outdoor unit and a plurality of indoor units. The plurality of units may be grouped into one or more groups. A wireless communication module may be provided at each of the plurality of units and configured to perform wireless communication using a Sub-GHz frequency band. The wireless communication module may include an encoder configured to encode a predetermined signal, a modulator configured to modulate the encoded signal according to Orthogonal Frequency Division Multiplexing (OFDM) using multiple subcarriers, at least one antenna having an antenna pattern formed on a Printed Circuit Board (PCB), and configured to output a signal based on the modulated signal, a demodulator configured to demodulate a signal received at the at least one antenna, according to the OFDM, and a decoder configured to decode the demodulated signal. Accordingly, a high-quality wireless communication environment may be implemented.

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。
