Abstract (en)
An air conditioner includes a compressor, the operation frequency of which is variable, and a controller for executing compressor protection control to raise the operation frequency of the compressor to a required operation frequency at the start of the cooling or heating operation. The compressor protection control includes a first protection control and a second protection control. In the first protection control, the operation frequency of the compressor is controlled such that the time period from the activation of the compressor to the time at which the operation frequency reaches the required operation frequency should become relatively long. In the second protection control, the operation frequency of the compressor is controlled such that the time period from the activation of the compressor to the time at which the operation frequency reaches the required operation frequency should be relatively short. The control unit executes the second protection control when the predetermined condition is satisfied at the time of executing the compressor protection control.
