The plurality of first heat exchanger tubes are arranged in a line. The first heat transfer section includes a plurality of first heat transfer tubes arranged such that the flow of the non-azeotropic mixed refrigerant flowing through the plurality of first heat transfer tubes is orthogonal to the flow of air flowing through the first heat transfer section. have. The heat exchanger further includes a second heat transfer section having a plurality of second heat transfer tubes. The second heat transfer section is arranged adjacent to the first heat transfer section. The plurality of second heat exchanger tubes are arranged in a line, and are arranged in a line along the direction in which the plurality of first heat exchanger tubes are lined up. The non-azeotropic mixed refrigerant flows through the plurality of second heat transfer tubes of the second heat transfer section. The second heat transfer section includes a plurality of second heat transfer tubes arranged such that the flow of the non-azeotropic mixed refrigerant flowing through the plurality of second heat transfer tubes is perpendicular to the flow of air flowing through the second heat transfer section. have. The inlet and outlet of the non-azeotropic mixed refrigerant of each of the first heat transfer section and the second heat transfer section are connected to a heat exchanger inlet and a heat exchanger outlet, respectively.
