Abstract

The invention relates to the technical field of train air returning, in particular to an air conditioner air returning system for a train, a train air conditioning device and the train. An air conditioner main machine is arranged in a train passing platform area; at a roof above the passing platform, an air return port is formed in the upper top surface of the end, connected with the passing platform, of a carriage; an air return channel and an air return pipe, communicating with each other, communicate with the air conditioner main machine and the air return port; and no air return channel isformed in the carriage. A first air return section connected with the air conditioner main machine is provided with a first silencing structure for eliminating noise of returning a cavity of the airconditioner main machine to the air return channel to prevent noise from entering the carriage; and a second air return section is provided with a second silencing structure on a second end surface for absorbing and reducing noise generated by impact on the second end surface by air currents and for absorbing the noise in the air return channel to achieve the noise reducing purpose.

Description

technical field [0001] The invention relates to the technical field of train air return, in particular to an air conditioner air return system for a train, a train air conditioner and a train. Background technique [0002] In my country, trains, especially fast trains, have become an important means of transportation for people to travel. After many railway speed increases, my country's railway passenger transport has entered the high-speed era of about 300km / h, and the design speed has been increased to 400km / h. [0003] Train air-conditioning units have gradually become one of the basic components of modern rail passenger vehicles, which are used to adjust the temperature and humidity in the passenger compartment and improve the air quality in the passenger compartment. The train passenger room air conditioning unit is mainly composed of shell, evaporator, condenser, compressor, throttling device, evaporating fan, condensing fan, controller and so on. [0004] The air su...
