Abstract (en)
An air conditioner according to one embodiment includes an outdoor unit, an indoor unit, a pipe, a battery unit, a permission unit, and a valve control unit. The indoor unit cools or heats an interior of a room with a refrigerant supplied from the outdoor unit. The pipe connects the outdoor unit and the indoor unit together and carries the refrigerant. The battery unit supplies power when supply of power from an AC power source is stopped. A shutoff valve opens and closes the pipe by the power from the AC power source or the power from the battery unit. The permission unit permits valve closure operation of the shutoff valve. The valve control unit closes the shutoff valve by the power from the battery unit when the supply of the power from the AC power source to the shutoff valve is stopped after permission from the permission unit, and before the permission from the permission unit, keeps the pipe open through the shutoff valve even if the supply of the power from the AC power source to the shutoff valve is stopped.
