Air-conditioning apparatus

Abstract

An air-conditioning apparatus is provided with an indoor unit and an outdoor unit connected to each other via a refrigerant pipe through which refrigerant flows. The air-conditioning apparatus includes a refrigerant detection unit configured to detect leakage of the refrigerant in the indoor unit, a notification unit configured to provide a notification of occurrence of leakage of the refrigerant, a communication unit capable of communicating with an external terminal device via a network, and a controller configured to control at least the notification unit and the communication unit. The notification unit includes at least one of a display unit and a speaker disposed on a surface of a casing of the indoor unit, and the external terminal device, in addition to a display unit disposed on a remote controller for operating the indoor unit. When leakage of the refrigerant is detected by the refrigerant detection unit, the controller controls the notification unit and the communication unit to provide a notification of occurrence of leakage of the refrigerant. Accordingly, a warning notification of refrigerant leakage is provided not only from the notification unit disposed on the indoor unit, but also from the external terminal device to attract more attention to the notification even from a user not in the vicinity of the indoor unit such that the user easily notices the notification and becomes fully aware of the refrigerant leakage.
