PROBLEM TO BE SOLVED: To provide an air conditioning system that allows smooth information transmission/reception processing to be performed by avoiding interruption of work due to the shortage of charged amount in a smart device when the management work of the air conditioning system is performed using the smart device, and to provide the smart device used in the air conditioning system, and a data communication method.SOLUTION: According to an embodiment, the smart device used in the air conditioning system comprises: a remaining amount monitoring unit for a storage battery; a device antenna; and a switching control unit. The remaining amount monitoring unit monitors the remaining amount of the storage battery in the smart device. The device antenna wirelessly communicates with an outdoor unit in the air conditioning system. If it is found that the remaining amount of the storage battery is equal to or less than a preset first threshold value, the switching control unit transmits a power supply request to the outdoor unit, and charges power wirelessly supplied via the device antenna in response to the transmission of the power supply request to the storage battery.SELECTED DRAWING: Figure 2 |
