Abstract
The disclosure prevents a state where a liquid refrigerant is likely to be accumulated in an outdoor heat exchanger upon small load operation at low outdoor temperature during cooling operation. A junction part is disposed between a path and a liquid side inlet-outlet port, and includes a junction flow passage configured to cause a refrigerant flowing from the path to the liquid side inlet-outlet port to join and flow therein. A branching passage has a first end connected to the path, and a second end connected to the junction flow passage. An outdoor heat exchanger is configured to increase, upon decrease in load, a flow rate ratio of a refrigerant flowing to the branching passage to volume of a refrigerant flowing to the path.
