The invention discloses a channel for supplying air oppositely for air conditioners of a railway vehicle. The channel is characterized in that two air conditioning units are respectively arranged at the first and second ends of the vehicle and are connected through a main air supply channel; the main air supply channel is separated into a left air supply cavity and a right air supply cavity through a diagonal separation plate. The main air supply channel is separated into the left air supply cavity and the right air supply cavity through the diagonal separation plate; the structure with the dual units for supply air oppositely is adopted, and air which is supplied into the main air channel at different speeds and with different vectors is mixed, so that the transverse air quantity and longitudinal air quantity of a passenger room are more uniform, the redundancy design of the air conditioning units of the passenger room is realized, and the reliability of the units is improved.
Description
technical field [0001] The invention relates to an air-conditioning air supply duct, in particular to an air-conditioning pair air supply duct of a rail vehicle. Background technique [0002] The traditional EMU air supply system is a one-way air supply structure. The existing problems are that the one-way air supply requires a large air volume, high wind speed, and large air duct resistance; the second is that the one-way air supply lacks redundancy. Consider that once the blower fails, the air supply capacity will also disappear; the third is that the one-way air supply has poor attenuation balance in the longitudinal direction of the passenger room, and the air volume is uneven. Contents of the invention [0003] The technical problem to be solved by the present invention is to mix the winds of different speeds and vectors sent into the main air duct by the two air-conditioning units in the passenger room, so that the horizontal and vertical air volumes sent to the pass...
