Abstract
The heat-medium cycle circuit includes a discharge mechanism including a discharge valve, the discharge mechanism being configured to, when the discharge valve is open, discharge air present inside the heat-medium cycle circuit to the outside of the heat-medium cycle circuit. The air-conditioning apparatus is configured to execute an air discharge operation mode in which the air present inside the heat-medium cycle circuit is discharged to the outside of the heat-medium cycle circuit. The air discharge operation mode includes a first operation mode, and a second operation mode performed after the first operation mode. The first operation mode is an operation mode in which, with the discharge valve being closed, an operation similar to a cooling operation is performed. The second operation mode is an operation mode in which, with the discharge valve being open, an operation similar to a heating operation is performed.
