Abstract:
To provide a highly efficient and reliable uninterruptible power supply device, and power supply method using the same, and an air conditioning system.
A control signal outputting means of an uninterruptible power supply device 3 outputs a command to keep operation state of a load (air conditioner 2) connected to the uninterruptible power supply device 3 based on the fact that a switching detecting means detects switching from a commercial power supply 1 to a storage battery 32. Thus, the uninterruptible power supply device 3 itself is prevented from being stopped as a protection function of the uninterruptible power supply device 3 is triggered.
