PROBLEM TO BE SOLVED: To provide an air conditioner capable of performing a high sensible heat control in response to a load without excess dehumidification and suppressing a dehumidification amount to a minimum, by detecting a dew-point temperature of sucked air, and to provide its control method. SOLUTION: The air conditioner comprises a variable displacement compressor 1, a condensation side heat exchanger 2 for condensing and liquifying gas refrigerant delivered from the compressor, a throttle device 3 for decompressing the liquified refrigerant from the condensation side heat exchanger, and an evaporation side heat exchanger 4 for evaporating and liquifying the refrigerant decompressed by the throttle device. The air conditioner also comprises a dry bulb temperature detecting means 7 or 8 for detecting temperature on the suction side or the discharge side of the evaporation side heat exchanger, a humidity detecting means 10 for detecting a humidity on the suction side of the evaporation side heat exchanger, and controllers 11 and 12 for controlling the compressor and the throttle device based on the detection results of the dry bulb temperature detecting means and the humidity detecting means.
