The surrounding air supply system comprises an air conditioner, an air supply duct, an air return duct and a fresh air inlet, the fresh air inlet and a waste exhaust outlet are formed in the top of the air conditioner, and an air outlet and a main air return inlet are formed in the bottom of the air conditioner; the air supply duct communicates with an air outlet of the air conditioner; the air return duct comprises a side air return duct and a main air return duct, the main air return duct communicates with a fresh air inlet and a waste air outlet of the air conditioner, and the lower end of the side air return duct communicates with an air return opening located in the lower portion of the side wall. According to the surrounding air supply system, airflow is downwards fed into the vehicle from the air supply outlet of the air supply duct and enters the air return duct from the air return inlet in the lower portion of the side wall, the air return duct is arranged in the side wall and the vehicle roof, a surrounding type air supply and return structure is formed, and the walking path of the airflow in the vehicle body is effectively prolonged; the cooling capacity or heat carried by the air flow can be conveniently and uniformly dispersed into the internal space of the vehicle body, and the function of adjusting the temperature in the vehicle is improved.
本发明提供了一种环抱送风系统及轨道车辆,包括空调、送风道、回风道以及新风进口,空调顶部设有新风进口及废排风口,底部设有出风口及主回风口;送风道与空调的出风口连通;回风道包括侧回风道和主回风道,主回风道与空调的新风进口和废排风口分别连通,侧回风道的下端连通有位于侧墙下部的回风口。本发明提供的环抱送风系统,气流从送风道的送风口向下送入车内、并从侧墙下部的回风口进入回风道,将回风道设置在侧墙和车顶内,形成环抱式送回风结构,有效地延长了气流在车体的行走路径,便于将气流携带的冷量或热量均匀地散布到车体的内部空间,提高了对车内温度的调节功能。
