Abstract

Provided is an air conditioner. The air conditioner includes an indoor unit and an outdoor unit. The outdoor unit includes a compressor, an outdoor heat exchanger, a supercooling unit for supercooling a refrigerant, a first refrigerant pipe allowing the supercooling unit to communicate with a suction side of the compressor, a first valve disposed in the first refrigerant pipe, a second refrigerant pipe connecting the compressor to the first refrigerant pipe, and a second valve disposed in the second refrigerant pipe. In a first refrigerant flow mode, a refrigerant flowing into the supercooling unit is introduced into the compressor through the second refrigerant pipe. In a second refrigerant flow mode, a refrigerant compressed by the compressor is discharged into the second refrigerant pipe.
