Abstract:

An outdoor heat exchanger (11) is provided with: a main heat exchange region (101); a sub-heat exchange region (201); and a connection pipe (35A) and a connection pipe (35C), which connect the main heat exchange region (101) and the sub-heat exchange region (201) to each other. The main heat exchange region (101) has a main heat exchange flow channel (33A) and a main heat exchange flow channel (33C). The sub-heat exchange region (201) has a sub-heat exchange flow channel (34A), a sub-heat exchange flow channel (34C), and a sub-heat exchange flow channel (34D). The connection pipe (35C) connects the sub-heat exchange flow channel (34C) and the sub-heat exchange flow channel (34D) to the main heat exchange flow channel (33C) by maintaining the state wherein the sub-heat exchange flow channels are joined together.
