PROBLEM TO BE SOLVED: To provide an air conditioner capable of stabilizing a state of a refrigeration cycle in a comparatively short time, even when an R32 refrigerant and a capillary tube are used.SOLUTION: An indoor unit control unit 6 which an indoor unit 2 includes controls so that rotational frequency of an indoor fan 5 becomes rotational frequency for stabilization facilitation which is faster than a normal target rotational frequency, during a certain period from an operation is started until a refrigeration cycle is stabilized. Thereby, temperature increase is achieved by facilitating heat exchange in a portion in which a temperature has dropped excessively out of an indoor heat exchanger 4, and deterioration of temperature balance of the entire indoor heat exchanger 4 can be reduced. Then, when the refrigeration cycle is brought into a stabilized state, the rotational frequency is dropped to the normal target rotational frequency. By such rotational frequency control, temperature drop is suppressed by increasing an inlet refrigerant temperature, and the time can be shortened until returning to the target temperature.SELECTED DRAWING: Figure 5 |
