Document Type and Number:
WIPO Patent Application WO/2018/169305
Kind Code:
A1
Abstract:
The present invention relates to an air conditioner comprising multiple units including outdoor units and indoor units, and a controller for monitoring and controlling the multiple units, wherein: the multiple units are installed so as to be distributed over multiple floors; each of the controller and the multiple units includes a communication unit for transmitting or receiving data by using a wireless communication technique; and the communication unit is configured to transmit or receive data at a frequency in a sub-gigahertz band. Accordingly, the present invention has advantageous effects, as follows: the multiple units of the air conditioner are configured to transmit or receive data by using a wireless communication technique, and thus direct wireless communication between indoor units or between an indoor unit and an outdoor unit is enabled, regardless of installation environment, and an indoor unit can communicate with the controller directly and not via the outdoor unit; installation of a separate communication line is not required, and thus the costs of the installation and operation can be reduced; a frequency of a signal to be used is specified by considering installation distances and obstacles in a building, and thus stable communication can be achieved even in a high-rise building and communication is enabled, regardless of obstacles; and direct communication between the units is possible, and thus the efficiency and stability in management and operation of the air conditioner can be improved.
