Abstract: An air conditioner is disclosed. The air conditioner comprises: a compressor for compressing a refrigerant; a discharge pipe for guiding the refrigerant discharged from the compressor; an accumulator for storing the refrigerant flowing into the compressor from an outdoor heat exchanger or an indoor heat exchanger; a suction pipe for guiding the refrigerant discharged from the accumulator to the compressor; a subcooler disposed in a pipe between the outdoor heat exchanger and the indoor heat exchanger so as to secure a degree of subcooling of the refrigerant; an injection pipe for guiding a refrigerant superheated in the subcooler to the compressor; and a fixing member provided for fixing the discharge pipe, the suction pipe, and the injection pipe together.
