Abstract
An air-conditioning apparatus includes a first transmission channel, a plurality of second transmission channels different from the first transmission channel, a controller connected to the first transmission channel and not connected to the second transmission channels, a plurality of air-conditioning indoor units connected to the second transmission channels and not connected to the first transmission channel, and a plurality of air-conditioning outdoor units. The plurality of air-conditioning outdoor units electrically connect the first transmission channel and the second transmission channels, and do not transmit a short-circuit state occurring in one of the first transmission channel and the second transmission channels to a transmission channel other than the one of the first transmission channel and the second transmission channels, thereby enabling communication between devices connected to the transmission channel other than the one.
