An indoor unit (1) includes: a casing (2); a heat exchanger (3) through which a flammable refrigerant flows; a fan (4); a detection sensor (6) detecting a leak of the flammable refrigerant; a warning device (7) emitting a warning about a leak of the flammable refrigerant; a control unit (5) controlling operations of the fan (4) and the warning device (7) ; and an operation device (11) inputting stop commands for the fan (4) and the warning device (7) to the control unit (5) based on its manual operation. Upon detection of a leak of the flammable refrigerant by the detection sensor (6), the control unit (5) starts up the fan (4) on condition that the fan (4) is at a stop, starts up the warning device (7), disregards a stop command for the fan (4) by the operation device (11), and permits a stop command for the warning device (7) by the operation device (11). As a result, a user is enabled to arbitrarily stop a warning started based on occurrence of a refrigerant leak. |
