Air-conditioning apparatus

An air-conditioning apparatus 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 comprising:

• a refrigerant sensor 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 transmitter capable of communicating with an external terminal via a network;
• and
• a controller configured to control operations of the indoor unit, and to control at least the notification unit and the transmitter;
• wherein the notification unit includes at least one of a display disposed on a surface of a casing of the indoor unit and a speaker disposed on the surface of the casing of the indoor unit;
• wherein at least one of the display and the speaker disposed on the surface of the casing of the indoor unit is apart from at least one of a temperature sensor and a light receiver disposed on the surface of the casing, the light receiver being configured to receive an operation signal having indoor unit settings from a remote controller, and
• wherein the controller is configured to
• determine whether leakage of the refrigerant is detected by the refrigerant sensor, and
• in response to determining that leakage of the refrigerant is detected, control both the notification unit to provide a notification of occurrence of leakage of the refrigerant and the transmitter to provide the notification of occurrence of leakage of the refrigerant via the network to the external terminal.
