力軽減される。(E) Function In the ceiling-embedded air conditioner of the present invention, the width of the air blowing noise generated by the blower, the sound transmitted indoors through the duct entrance and the duct is attenuated when passing through the duct, so The sound transmitted to the device is reduced as much as possible. In addition, the sound transmitted into the room via the heat exchanger and the suction ventilation path is attenuated when passing through the heat exchanger and the suction ventilation path, so the sound transmitted into the room is reduced as much as possible. Furthermore, the sound transmitted from the blower into the room via the suction opening, the suction ventilation path, and the suction opening is suppressed as much as possible by the sound-dampening wall that isolates the blower. The sound that is transmitted to the road and then transmitted into the room via the suction opening is also reduced as much as possible.
