Abstract: An air conditioner of the present invention includes temperature distribution detecting means 12 for detecting a temperature distribution in a room 1, refrigerant leakage detecting means 13 for detecting refrigerant leakage, air-blowing means 14, air-blowing control means 17c for controlling air-blowing means 14, and wind-direction control means 17d for controlling a wind direction of the air-blowing means 14. When the refrigerant leakage detecting means 13 detects refrigerant leakage, the air-blowing control means 17c and/or the wind-direction control means 17d disperses a leaked refrigerant in a direction different from inhabitants 3 and a heat source apparatus 4 detected by the temperature distribution detecting means 12 thereby enhancing the energy efficiency and safety when a flammable refrigerant is used as a refrigerant.
