Patent attributes
In an air-conditioning apparatus, an indoor unit and an outdoor unit are connected to each other by a refrigerant pipe through which refrigerant flows. The air-conditioning apparatus includes: a refrigerant detection unit that detects a leak of the refrigerant in the indoor unit; a notification unit that makes a notification indicating occurrence of the leak of the refrigerant; a controller that controls at least the notification unit; and a remote control unit configured to operate the indoor unit. When the refrigerant detection unit detects the leak of the refrigerant, the controller controls the notification unit to make in a first mode the notification indicating the occurrence of the leak of the refrigerant, and make the notification in a second mode different from the first mode after a predetermined time period elapses from time at which the notification in the first mode is made. Thus, since the notification of the refrigerant leak is made two steps, that is, in the first mode in a first step and in the second mode in a second step, it is possible to cause a user to pay more attention to the notifications, and thus cause the user to easily notice the notification. It is therefore possible to cause the user to sufficiently know the refrigerant leak.
