PROBLEM TO BE SOLVED: To provide an air conditioner comprised of a refrigerant circuit for increasing a super-cooling when a cooling operation is carried out. SOLUTION: A mixture R407C of three refrigerants is separated at a receiver tank 6 into liquid phase refrigerant (a) comprised of R32 and R125 liquefied through a first outdoor heat exchanger 2a and gaseous phase refrigerant (b) composed of R134a. The liquid phase refrigerant is branched to flow toward a single path of a second outdoor heat exchanger 2b and a plurality of paths of the second outdoor heat exchanger.
