AIR CONDITIONING DEVICE |
摘要 |
To provide an air-conditioning apparatus that reduces large refrigerant noise generated when changing an operation mode. In an air-conditioning apparatus 100, when switching to a second operation mode from a first operation mode, switching to the second operation mode is performed after a predetermined time has elapsed after controlling either or all of expansion devices, controlling either or all of second flow switching devices, and controlling either or all of a first on-off device and a second on-off device such that a pressure difference of a heat source side refrigerant before and after each of the expansion devices is smaller compared to that in an operation state of the first operation mode. |
