PROBLEM TO BE SOLVED: To provide a control device capable of adjusting the drift of a refrigerant even if an outlet of an evaporator is in a saturated state or a wet state, and operating an air conditioner with maximum efficiency. SOLUTION: The control device of the air conditioner includes an adjustment valve 7 disposed at a flow channel inlet of an evaporator 6 having a plurality of flow channels, a refrigerant temperature detecting means 8 disposed at a flow channel outlet of the evaporator 6, a saturation temperature acquiring means for acquiring a saturation temperature of a refrigerant flowing in the evaporator 6, a temperature detecting means 10 for a discharged refrigerant of the compressor 2, and a control section 13 capable of controlling an opening of the adjustment valve 7. The control section 13 adjusts the opening of the adjustment valve 7 so that the refrigerant temperature at the flow channel outlet of the evaporator reaches a target evaporator outlet temperature obtained by adding a prescribed value to the saturation temperature acquired by the saturation temperature acquiring means, and then readjusts the opening of the adjustment valve 7 so that the temperature of the discharged refrigerant reaches a prescribed temperature.
