WIPO Patent Application WO/2022/195659

A1

An outdoor heat exchanger (1) is provided with: a group of upwind flattened tubes comprising a plurality of first flattened tubes (201) and a plurality of second flattened tubes (202); a group of downwind flattened tubes comprising a plurality of third flattened tubes (301) and a plurality of fourth flattened tubes (302), and located further downwind in the air flow direction than the group of upwind flattened tubes; and a distributor (10) that distributes the refrigerant flowing in from the center to the plurality of third flattened tubes (301) through multiple branches. When the outdoor heat exchanger (1) acts as an evaporator, the refrigerant flows through the plurality of second flattened tubes (202), the plurality of fourth flattened tubes (302), the plurality of third flattened tubes (301), and the plurality of first flattened tubes (201) in that order, and when the outdoor heat exchanger (1) acts as a condenser, the refrigerant flows through the plurality of first flattened tubes (201), the plurality of third flattened tubes (301), the plurality of fourth flattened tubes (302), and the plurality of second flattened tubes (202) in that order.
