The invention provides a ventilation system for a high-low floor motor train unit. The ventilation system is characterized by comprising an air conditioning unit, a roof air return duct, a roof air supply duct, an in-train exhaust duct, an in-train air return duct, an in-train air supply duct, a side wall lower air opening, a side wall air return cavity and an air return soft air duct; the first end of the air conditioning unit is connected with a middle roof air supply duct and roof air return ducts on the two sides. In-vehicle air supply ducts are arranged in the middle in the vehicle length direction, and in-vehicle air return ducts are arranged on the two sides; the roof air return duct is connected with the in-vehicle air return duct, and the roof air supply duct is connected with the in-vehicle air supply duct; side wall air return cavities are formed in the side walls, the two sides of the roof air return channel are connected with the side wall air return cavities through air return soft air channels, and the lower ends of the side wall air return cavities are connected with side wall lower air openings. Air flow uniformity of high and low floor areas and different heights in a vehicle is achieved, air flow noise is reduced, the installation space is saved, and the weight is reduced.

    本发明提供一种用于高低地板动车组的通风系统,其特征在于:包括空调机组、车顶回风道、车顶送风道、车内排风道、车内回风道、车内送风道、侧墙下部风口、侧墙回风腔和回风软风道;空调机组第一端连接中部的车顶送风道和两侧的车顶回风道;车内沿车长方向中部设置车内送风道,两侧设置车内回风道;车顶回风道连接车内回风道,车顶送风道连接车内送风道;侧墙内设置侧墙回风腔,车顶回风道两侧通过回风软风道连接侧墙回风腔,侧墙回风腔下端连接侧墙下部风口。本发明实现车内高低地板区域、不同高度的气流均匀性,降低了气流噪声,节省安装空间,降低重量。
