PROBLEM TO BE SOLVED: To further improve comfort by setting the minimum speed to a lower value than before when the load of a compressor is light, securing safety, and achieving a fine room temperature adjustment. SOLUTION: An outdoor machine control part 10 receiving an operation frequency code from an indoor machine control part 12 performs the inverter control of a compressor 4 that constitutes a refrigeration cycle. The outdoor machine control part 10 starts a timer A of a timer part 10c performs the clocking of a specific time Ta from the activation of the compressor 4 and at the same time sets the minimum speed of the compressor 4 to a higher value for the specific amount of time Ta. After the specific amount of time Ta according to the timer A passes, the minimum speed of the compressor 4 is varied and set according to an external air temperature detected by an external air temperature detection part 10a and at the same time a timer B of a timer part 10c is started at each a specific amount of time Tb, and the minimum speed of the compressor 4 is varied and set according to an external air temperature at each specific amount of time Tb. |
