The embodiment of the invention provides an air supply and return system, a carriage and a railway vehicle, the air supply and return system comprises an air conditioning unit and an air duct, the air duct comprises an air supply duct, an air return and exhaust shared duct and an air return pipeline, the air supply duct is connected with a unit air supply outlet of the air conditioning unit, and an air supply outlet is formed in the bottom of the air supply duct; the air return and exhaust shared air duct is connected with a unit air return port and a unit waste exhaust port of the air conditioning unit, and is arranged side by side with the air supply duct; the air return pipeline is connected with the air return and exhaust shared air duct, and an air return opening is formed in the lower end of the air return pipeline and used for extending to the position below a seat in the compartment along the side wall of the compartment. The return air inlet is formed in the position, close to the floor, of the bottom of the side wall of the carriage, so that air emitted from the top plate and air in the carriage are fully mixed and then enter the air return and exhaust shared air duct, and the air return and exhaust shared air duct and the return air pipeline prevent noise of the air conditioning unit from directly entering the carriage; and the influence of noise of the air conditioning unit on passengers in the compartment is reduced.
本申请实施例提供了一种送回风系统、车厢及轨道车辆,送回风系统包括空调机组和风道,风道包括送风风道、回排风共用风道和回风管路,送风风道与空调机组的机组送风口连接,送风风道的底部具有送风口;回排风共用风道与空调机组的机组回风口和机组废排风口连接,且与送风风道并排设置;回风管路与回排风共用风道连接,回风管路的下端具有回风口,回风口用于沿车厢的侧墙延伸至车厢内的座椅下方处。本申请将回风口设置在车厢侧墙底部靠近地板的位置,使从顶板上散出的空气与车厢内的空气充分混合后再进入回排风共用风道,而且回排风共用风道和回风管路阻挡了空调机组噪声直接进入车厢内部,降低了空调机组噪声对车厢内乘客的影响。
