Openable/closable covers are provided to the second inlet. The covers are closed when a silent operation mode is set by an operation unit. When the covers are closed, the second inlet is closed, and the sound caused by a hissing indoor fan in the indoor unit and the sound of the refrigerant flowing in the indoor heat exchanger of the indoor unit will not leak to the outside of the indoor unit.
