AbstractThe present invention relates to air conditioner which is capable to enable operation of a high-pressure switch to be judged in a short period of time. The air conditioner comprises a refrigerant circulating circuit for circulating refrigerant discharge from a condenser to an evaporator, a current sensing means for sensing an operating current of the compressor, a microcomputer for discriminating an operating state of the compressor on the basis of detection result; a driving means for receiving the instruction from the microcomputer and driving the compressor, a high-pressure switch inserted in an electric circuit of the driving means in series and operated, in response to a discharged pressure of the compressor. The microcomputer discriminates activation of the high pressure gas switch, in reference to a result of sensing operation of the current sensing means.
