Disclosed is a low-noise air conditioner ventilation system for a railway passenger car. The system comprises an air-conditioning air duct (1) and an air-conditioning unit (6), a waste exhaust fan (67) and a waste exhaust air duct (68) are arranged in the air-conditioning unit, a multi-layer sound insulation and noise reduction structure is arranged on a bottom plate (69) of the air-conditioning unit, and a labyrinth silencing structure (4) is arranged at a waste exhaust air inlet of the waste exhaust air duct. An inlet of the labyrinth silencing structure communicates with a passenger room, and an outlet of the labyrinth silencing structure is connected with the waste discharge air inlet; the multi-layer sound insulation and noise reduction structure comprises damping adhesive cement (691), sound absorption cotton (692), sound insulation felt (693) and a fixing plate (694), wherein the damping adhesive cement (691), the sound absorption cotton (692) and the sound insulation felt (693) are sequentially laid on a bottom plate of the air conditioning unit, and the fixing plate (694) is fixedly connected to the air conditioning unit. The exhaust noise of the air conditioning unit is reduced, and the riding comfort of passengers in a passenger room is greatly improved.
