Abstract: An air conditioner is provided. The air conditioner includes a compressor for compressing a refrigerant, an oil separator for separating an oil of the refrigerant discharged from the compressor to collect the separated oil into the compressor, a condenser for condensing the refrigerant separated from the oil separator, and a supercooling part in which a main refrigerant that is the refrigerant condensed by the condenser is heat-exchanged with a branch refrigerant branched from the main refrigerant. At least a portion of the oil collected into the compressor passes through the supercooling part.
