Shake pads, connects ferrum and fix.
2nd, air-conditioner air outlet connects main air duct air inlet by the soft air duct positioned at 1/4 position of train, and the main air duct enters
Dividing plate is provided with air port, main air duct air inlet is divided into two by the dividing plate, the main air duct include to it is in-car extend the
One air channel and the second air channel extended to car end, the lower end of the dividing plate is connected with deflector, is blown into the wind Jing water conservancy diversion of main air duct
Plate is respectively fed to the first air channel and the second air channel, and noise reduction material is pasted on the dividing plate and deflector.
3rd, the soft air duct is tubular air channel made by artificial leather canvas.
4th, the upper end of the soft air duct passes through flange connection air conditioner air outlet, and lower end is fixed on main air duct air intake by snap ring
On mouth.
5th, first air channel is located in the middle part of vehicle, and the second air channel is located at vehicle end.
The present invention sets return air channel between side top plate of guest room and both walls respectively, meanwhile, hold level with both hands in car return air is set on top
Mouthful.A part of this return air channel of Jing of in-car circulation air is into roof upper space and flows back to unit, and another part is held level with both hands by car
Unit is directly flowed back in fight back air port.In-car air current composition is This improves, humiture field, speed field uniformity is improve, it is excellent
In-vehicle air environment is changed.Jing testing surfaces, the air return system effect is significant are applicable to various EMUs air-conditioning air blow and returns,
Or similar railway vehicle air conditioner ventilation.
Additionally, the present invention is provided with dividing plate in the air inlet of main air duct, air intake is divided into two, and will using deflector
Air-conditioner wind is respectively fed to first air channel and the second air channel of main air duct, so as to realize to the balanced ventilation in guest room, air current composition
Evenly distributed, air channel will not form dead band vortex, therefore noise is less；And noise reduction material is pasted on dividing plate and deflector, can be had
Effect reduces the noise in air conditioning unit incoming guest room, and erasure effect is very good；Pass through light air between main air duct and air-conditioner air outlet
Road connects, and the material of soft air duct is artificial leather canvas, and the error that can be produced in effectively adjusting main air duct installation process is greatly convenient
Workman's installation operation.
