An air conditioner having a first circulation channel which drives a thermodynamic cycle while normally circulating a refrigerant, a second circulation channel which is branched from an outlet of a condenser of the first circulation channel to recover oil from the refrigerant to a compressor and to cause the refrigerant to pass through a supercooling heat exchanger, and a third circulation channel which is directly branched from an evaporator of the first circulation channel to recover oil from the refrigerant and to the compressor and to cause the refrigerant to pass through the supercooling heat exchanger, thereby preventing the wet compression of the compressor to achieve improved reliability of the compressor, and preventing the degradation of heat-exchange performance.
