PURPOSE:To match the cooling capacity of an air conditioner to an air conditioning load in a short time after an electric recovery by setting the driving frequency of a compressor at the time of operating before power interruption to a target frequency at the time of starting when power is recovered after the interruption and restarting. CONSTITUTION:A control command for automatically restarting an operation when an air conditioner is once stopped and then recovered if a power source 7 is interrupted is assembled with a microcomputer 6. Further, the microcomputer 6 stores the driving frequency of a compressor 2 in a memory in the microcomputer 6 during operation. If the power source 7 is recovered after its interruption, the conditioner is stopped by the power interruption, and automatically started by the recovery. The target driving frequency of the compressor 2 at the time of starting is set to the driving frequency immediately before the power interruption stored in the memory in the microcomputer 6, and started via a compressor inverter driver 2. |
