The invention discloses a low-noise air conditioner air duct of a railway passenger car. The low-noise air conditioner air duct comprises an air conditioner return air inlet (3), an air conditioner air supply outlet (2), an air supply channel and an air return channel (11), the air conditioner air supply outlet is connected with the air supply channel, a silencer (7) is arranged in the air supply channel below the air conditioner air supply outlet, and the silencer comprises a left arc plate (701) and a right arc plate (702); the adjacent sides of the left arc plate and the right arc plate are connected into a whole, and the opposite sides of the left arc plate and the right arc plate extend towards one end of the air supply channel in an arc shape. The two ends of the left arc plate and the two ends of the right arc plate are sealed through reinforcing rib plates (704) correspondingly, so that a sound absorption cavity is defined by the left arc plate, the right arc plate, the air supply channel bottom plate and the reinforcing rib plates at the two ends. Sound absorption micropores (03) are evenly distributed in the left arc plate and the right arc plate respectively, and the sound absorption cavity is filled with sound absorption cotton used for absorbing noise of the air conditioning unit. The low-noise air conditioner air duct is convenient to process, and the riding comfort of passengers in the passenger compartment is greatly improved.
