An air-conditioning apparatus includes a refrigerant circuit formed by connecting pipes, a compressor including a compression chamber and an injection port through which refrigerant is introduced into the compression chamber, a first heat exchanger, a subcooling heat exchanger that includes a first flow passage and a second flow passage and exchanges heat between refrigerant flowing in the first flow passage and refrigerant flowing in the second flow passage to subcool the refrigerant flowing in the first flow passage, a first expansion device, a second heat exchanger, and an accumulator In addition, a first bypass pipe connects the second flow passage of the subcooling heat exchanger with a segment of the pipes, positioned on a refrigerant inflow side of the accumulator; an expansion device to adjust a flow rate of the refrigerant flowing in the first bypass pipe; a second bypass pipe that connects a segment of the pipes with the injection port, the segment being positioned between the first heat exchanger and the second heat exchanger; and an expansion device to adjust a flow rate of the refrigerant flowing in the second bypass pipe.
