Abstract
A kind of super-silent air-conditioning system used for rail vehicle includes the air-conditioner set of both ends air-supply both ends air-return, it is characterised in that：Air-conditioner set both ends are respectively provided with sound attenuator, sound attenuator is equipped with air-supply air inlet, air-supply air outlet, return air air inlet, return air air outlet, and air-supply air inlet, air-supply air outlet, return air air inlet, return air air outlet are connect by connecting air duct with air-conditioner set air outlet and return air inlet respectively.The wind that is sent to interior air duct by the utility model is more stable, evenly, and 6400m is up in single air conditioner unit blasting air amount3In the case of/s, internal car noise can be controlled in 56dB（A）Within；Have both ends air-supply both ends return air unit fan resistance be small, wind speed is small and the advantages that uniformity is adjusted well in air duct, while also having lower air-supply blower fan group can not set special air conditioner group platform, be easy to drain next time；Can air outlet be set in all positions in vehicle commander direction, car air-supply is without dead zone.
Description
Technical field
The utility model belongs to technical field of rail traffic, and in particular to a kind of super-silent air-conditioning system for rail vehicle
System.
Background technology
With the development of society, people go out, frequency is higher and higher, and wherein rail vehicle becomes the important friendship of people's trip
Logical tool, everybody requires also to be increasingly stringenter to the comfort of rail vehicle, and wherein rail vehicle noise is to judge rail vehicle
One important indicator of comfort.When the country is to city railway vehicle stationary vehicle, internal car noise requires to be not more than from past
72dB（A）, change in order to which present is not more than 69dB（A）, the even requirement of some external projects is no more than 60dB（A）.It faces
The air-conditioner set of the noise requirements being increasingly stringenter, the lower return air of the lower air-supply of tradition or both ends air-supply both ends return air is due to interior return air
Mouth and air outlet are close apart from pressure fan, it is difficult to meet noise requirements of the market to rail vehicle.It must be effectively reduced thus
The noise that air-conditioner set and air duct generate, improve passenger is comfort level.
Utility model content
The utility model solve the technical issues of be：Overcome the deficiencies of the prior art and provide a kind of super-silent rail vehicle
With air-conditioning system, it is equipped with sound attenuator on air-conditioning duct, disclosure satisfy that rail vehicle air conditioner group noise requirements standard.
To achieve the above object, the utility model provides a kind of super-silent air-conditioning system used for rail vehicle, including both ends are sent
The air-conditioner set of wind both ends air-return, it is characterised in that：Air-conditioner set both ends are respectively provided with sound attenuator, sound attenuator be equipped with blow into
Air port, air-supply air outlet, return air air inlet, return air air outlet, air-supply air inlet, air-supply air outlet, return air air inlet, return air go out
Air port is connect by connecting air duct with air-conditioner set air outlet and return air inlet respectively.
Further, the air-supply air outlet, return air air inlet are located at noise reduction lower box part, air-supply air inlet, return air air outlet
Positioned at sound attenuator end.
The good effect of the utility model：
（1）The utility model makes full use of the space on steel structure of car roof top, in overhead type both ends air-supply both ends return fan
Group both ends are provided with two sound attenuators, and sound attenuator not only effectively reduces equipment acoustic noise to interior transmission, also guide functions, makes
The wind that is sent to interior air duct is more stable, evenly.According to test result, using the air-conditioning system of this result, in single air conditioner
Unit blasting air amount is up to 6400m3In the case of/s, internal car noise can be controlled in 56dB（A）Within.
（2）The utility model is converted under sound attenuator under air-supply unit both ends air-supply both ends air return method to by sound attenuator
Air return method had both had a both ends air-supply both ends return air unit fan resistance is small, wind speed is small in air duct and uniformity is adjusted well etc. and is excellent
Point, at the same also have it is lower air-supply next time blower fan group can not set special air conditioner group platform, be easy to draining etc. advantage.
（3）The air-conditioner set of return air or both ends air-supply both ends return air under traditional lower air-supply, noise in order to control, generally away from
The air delivery duct lower zone closer from pressure fan is not provided with air outlet, and otherwise the noise in unit can directly be passed to car.This reality
With novel since air-conditioner set both ends are equipped with sound attenuator, can air outlet, car air-supply nothing be set in all positions in vehicle commander direction
Dead zone.
Description of the drawings
Fig. 1 is the utility model structure diagram；
Fig. 2 is the air-conditioner set air blow and return schematic diagram described in the utility model；
Fig. 3 is the sound attenuator air blow and return schematic diagram described in the utility model.
Specific implementation mode
The utility model is further described presently in connection with attached drawing.
Refering to fig. 1, Fig. 2, Fig. 3, air-conditioning return air blowing system described in the utility model include：Both ends air-supply both ends return air
Air-conditioner set 1, noise reduction bellows 2 and the connection air duct 3 and 4 for connecting air-conditioner set and noise reduction bellows.Unit blasting air passes through
Air outlet 5 enters in air-supply connection air duct 3, enters back into noise reduction bellows air-supply air inlet 8, then blows out from noise reduction bellows
Air port 9 is out sent in guest room air duct.Unit return air enters from air -return duct inside guest room in noise reduction bellows return air air inlet 10,
Out enter from noise reduction bellows return air air outlet 7 again in return air connection air duct 4, machine is then returned to by air-conditioner set return air inlet 6
In group.
