Air Conditioner

An air conditioner comprising:

• a heat exchanger that includes a plurality of heat transfer pipes, through which a refrigerant flows, and performs heat exchange with air, wherein
• the heat exchanger includes one end section and the other end section,
• the plurality of heat transfer pipes are disposed to extend back and force between the one end section and the other end section in a state in which the heat transfer pipes are arranged in a direction crossing a direction in which the air flows, and rows of the plurality of heat transfer pipes arranged in the crossing direction are configured to be arranged in at least two rows along the direction in which the air flows,
• the two rows include a first row located most upstream in the direction in which the air flows and a second row located adjacent to the first row in the direction in which the air flows,
• the plurality of heat transfer pipes include a first heat transfer pipe and a second heat transfer pipe adjacent to each other in the second row, the first heat transfer pipe and the second heat transfer pipe extend from the other end section to the one end section in the second row and are combined in the one end section to be a first combined pipe, and the first combined pipe is configured to extend back and force once between the one end section and the other end section in the first row,
• the refrigerant is R32 or a refrigerant containing 70 wt. % or more of R32,
• the heat exchanger includes a plurality of fins attached around the plurality of heat transfer pipes, and
• the plurality of fins are tabular and, when plate thickness of the fins is represented by t [mm] and an interval of the fins adjacent to each other is represented by pf [mm], 0.06≤t/pf≤0.12 is established.
