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.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
