ABSTRACT:
An air-conditioning system capable of reducing traffic of signals and effectively performing control and management operations without causing heavy traffic is obtained. In an air-conditioning system including one or more indoor units200, one or more outdoor units100, and a centralized control apparatus300and performing signal communication, a transmission relay400is provided between a first transmission line500to which the one or more outdoor units100and the centralized control apparatus300are connected and a second transmission line510to which one or more indoor units200constituting a group are connected, the transmission relay400relays a signal between the first transmission line500and the connected second transmission line510. The transmission relay400further includes arithmetic processing means430for processing data included in the signal transmitted via the connected second transmission line510, and data storage means440for storing data regarding the processing by the arithmetic processing means430.
