In cooling, when the backup air conditioner is used in a room connected to the air circulation duct, the temperature detected by the circulating air temperature detection sensor falls below the set value, the cooling operation of the base air conditioner is stopped, and the room connected to the exhaust duct. When the room temperature rises due to the stop of the backup air conditioner and the temperature detected by the exhaust temperature detection sensor becomes higher than the temperature detected by the circulating air temperature detection sensor, the controller uses the determination means and the information source switching means to control the exhaust temperature detection sensor. It operates so as to maintain the detected temperature below the set value, and it is possible to reliably maintain the cooling base temperature (about 28 ° C) in the room connected to the exhaust duct.
