Abstract: Provided is a communication system for an air conditioner including a housing and a control board accommodated in the housing. The communication system includes: a communication conversion unit accommodated in the housing and configured to acquire a required electric signal from the control board and to convert the electric signal into a digital signal for wire transmission; a cable having a first end connected to the communication conversion unit, the cable being drawn out of the housing to outside; and an antenna unit connected to a second end of the cable located outside the housing, the antenna unit being configured to establish wireless communication with a base station.

Abstract: An air-conditioner communication system includes: a ceiling-embedded air conditioner; a wireless local area network (LAN) adapter attached to the air conditioner and that functions as a network communication unit of the air conditioner; a router that configures a LAN; a server that communicates with the router via a telecommunication line; and a terminal device that communicates with the wireless LAN adapter and that includes a display. The wireless LAN adapter is connected to the LAN, acquires connection information that indicates whether the wireless LAN adapter is in communication with the router, and provides the terminal device with the connection information. The terminal device displays indicates, on the display based on the connection information, whether the air conditioner, the wireless LAN adaptor, the router, and the server are in communication with one other.
