Beschreibung
Zusammenfassung:	An air conditioner (201) includes a switching valve (202), a flow rate restricting portion (104) and an on-off valve (204). The switching valve (202) is provided in a flow path between a compressor (10) and an outdoor heat exchanger (40). The outdoor heat exchanger (40) includes a heat exchange portion (40A) and a heat exchange portion (40B). During heating operation, the switching valve (202) causes a second connection port (B1), a third connection port (B2) and a first connection port (A) to communicate with one another. The flow rate restricting portion (104) and the on-off valve (204) are connected in series between an outlet and an inlet of the compressor (10) during the heating operation, to bypass a part of refrigerant. During defrosting operation of the heat exchange portion (40A), the switching valve (202) is configured such that a fourth connection port (C) and the second connection port (B1) communicate with each other, and the third connection port (B2) and the first connection port (A) communicate with each other.
