Air conditioning apparatus

An air conditioning apparatus that performs air conditioning operation, comprising

• a heat exchanger including a first heat-exchanging portion and a second heat-exchanging portion,
• the first heat-exchanging portion and the second heat-exchanging portion each including
• a plurality of flat tubes that are arranged in a first direction, inside of which refrigerant flows,
• the plurality of flat tubes each having
• two extending portions extending in directions different from each other on a plane orthogonal to the first direction, when viewed in the first direction, and
• a coupling portion coupling the two extending portions to allow an angle (α, β) formed between the directions in which the two extending portions extend to be smaller than 180 degrees, when viewed in the first direction, wherein
• a plurality of the extending portions arranged in the first direction of the first heat-exchanging portion
• form first tube rows,
• a plurality of the extending portions arranged in the first direction of the second heat-exchanging portion
• form second tube rows,
• the second heat-exchanging portion
• is disposed adjacent to the first heat-exchanging portion to allow a plurality of the coupling portions and the second tube rows to be positioned between the two first tube rows of the first heat-exchanging portion, and
• the first heat-exchanging portion and the second heat-exchanging portion
• are coupled to each other via a coupling tube to allow a flow of the refrigerant to be in series.
