Abstract (en)
[origin: EP4310427A1] An outdoor heat exchanger (1) includes: a group of windward flat tubes including a plurality of first flat tubes (201) and a plurality of second flat tubes (202); a group of leeward flat tubes including a plurality of third flat tubes (301) and a plurality of fourth flat tubes (302) and disposed at a leeward position with respect to the group of windward flat tubes in a flow direction of air; and a distributor (10) that distributes refrigerant that flows in from a center of the distributor to the plurality of third flat tubes (301) through a plurality of branches. When the outdoor heat exchanger (1) acts as an evaporator, the refrigerant flows through the plurality of second flat tubes (202), the plurality of fourth flat tubes (302), the plurality of third flat tubes (301), and the plurality of first flat tubes (201) in this order, and when the outdoor heat exchanger (1) acts as a condenser, the refrigerant flows through the plurality of first flat tubes (201), the plurality of third flat tubes (301), the plurality of fourth flat tubes (302), and the plurality of second flat tubes (202) in this order.
