Kind Code:
An air conditioner duct of a rail train and the rail train comprising the air conditioner duct. The air conditioner duct of the rail train comprises a passenger compartment air duct (1) and a driver cab main air duct (2). The passenger compartment air duct (1) comprises a cold air cavity (11), two warm air cavities (12), a first fresh air cavity (13), and a distribution valve for regulating and controlling the ratio of supplied cold and warm air. The driver cab main air duct (2) comprises a middle air cavity and two side air cavities (23); one side of the middle air cavity is provided with a second fresh air cavity (24) for communicating with the first fresh air cavity (13); the middle air cavity comprises an upper air cavity (21) and a lower air cavity (22); the upper air cavity (21) and the lower air cavity (22) are separated and isolated from each other by means of a gradient separator; a valve is provided on the gradient separator. The air conditioner duct can satisfy the requirements for multi-functionality; cold air and warm air are conveyed separately, thereby achieving good uniformity; air duct structures are integrated, thereby saving the space; moreover, when a driver cab requires emergency ventilation, the valve is switched on, air goes out via an air port communicated with the middle air cavity, and the passenger compartment air duct performs emergency air supply for the driver cab, so that the emergency handling capability is improved.
