Description
Technical field
The present invention relates to railway vehicle air conditioner systems, and in particular to a kind of air-conditioning system of the low static pressure of low noise.
Background technique
With the development of society, people go out, frequency is higher and higher, everybody to the noise requirements of rail vehicle also increasingly
Strictly.City railway vehicle passenger capacity is big, and air-conditioning system air quantity is big, and noise is also larger.Return air air conditioner under blowing under overhead type
For group due to simple with roof interface, unit height is smaller, is widely applied in city railway vehicle.But lower return air is sent under at present
The pressure fan of unit and the equal centralized arrangement in air port is sent back in one end of air-conditioner set, every trolley sets two air-conditioner sets, unit
It sends air port back to be arranged at the 1/4 of length over ends of body, 3/4 liang, each pressure fan is responsible for that interior air duct air supplying distance is long, and needing will be more
A air duct is connected with flange, and structure is complicated, erroneous for installation, and wind speed is big in air duct, and air-supply uniformity is difficult to adjust, and needs to set
It sets a large amount of deflector and adjusts air-supply uniformity, duct resistance is big, and unit static pressure is high, and internal car noise is big, especially for air quantity
Biggish A type railcar, return air inlet underface noise is in 70dB(A) left and right, seriously affect experiencing by bus for passenger.
Summary of the invention
The object of the present invention is to provide one kind in the case where refrigerating capacity is big, air quantity is high, and structure is simple, easy for installation, low
The railway vehicle air conditioner return air blowing system of the low static pressure of noise, to overcome current track vehicle air conditioner, structure is complicated, noise is big,
Take uncomfortable drawback.
For achieving the above object, the present invention provides a kind of low noise low static pressure railway vehicle air conditioner system, including sky
Adjust unit and air delivery duct, it is characterised in that: every trolley sets two air-conditioner sets, and the blower of air-conditioner set is vertically arranged in air conditioner
The both ends of group, make blower blow downwards, and the both ends of unit bottom are arranged in corresponding air outlet and return air inlet, and each air outlet connects
Lead to corresponding air duct.
Two air-conditioner sets are separately positioned at the 1/4 of roof length direction, 3/4.
The air outlet of the air-conditioner set is arranged at 1/8,3/8,5/8, the 7/8 of length over ends of body everywhere, in this way, each
The interior air-supply length that pressure fan is responsible for halves, and wind speed halves in air duct, substantially reduces unit static pressure, noise.
The each air outlet two sides in the air-conditioner set bottom respectively set a return air inlet, totally 4 return air inlets.
The advantages and positive effects of the present invention:
(1) compared with sending lower air return method under traditional, the interior air-supply length that each pressure fan is responsible for halves, wind speed in air duct
Halve, it is square directly proportional due to on-way resistance and speed, it is directly proportional to length, so air duct on-way resistance is only original 1/
8。
(2) due in air duct wind speed halve, dynamic pressure reduce, static pressure variation it is smaller, air-supply has good uniformity, nothing in air delivery duct
Deflector need to be set, and local resistance is greatly reduced, and structure is simple, and air duct is easy to clean.
(3) according to test result, using the air-conditioning system of this structure, the outer static pressure of machine be blower centralized arrangement at one end under
1/8 or so of blower fan group (air output is identical) next time is sent, power of fan can be effectively reduced, it is energy saving.
(4) since wind speed halves, internal car noise can reduce the left and right 6dB (A).
(5) since the air supplying distance of each blower is short, an air duct is only arranged in each blower, is not necessarily to multiple air ducts
It connects, structure is simple, easy for installation.
(6) blower centralized arrangement send down at one end next time blower fan group return air inlet be arranged in unit width direction
The heart, so return air inlet must be separately provided in built-in top plate immediately below unit, influences beauty since there are air delivery duct in two sides below unit
It sees.The two sides at unit bottom both ends are arranged in return air inlet of the invention, and return air inlet (grid) may be provided at built-in top plate two sides, with
For supply grille on same vehicle section, grid is supply grille in air-supply region, is return air grid in return air region, send
Style grid and return air grid are perfectly combined together.

Specific embodiment
- Fig. 4 refering to fig. 1, air-conditioning system of the present invention include: blow under both ends lower return air air-conditioner set 1, air delivery duct
5 and supply grille 7 and return air grid 8, every unit two pressure fan 2 are set, be arranged in both ends of unit and downward
Air-supply.Two unit blasting air mouths 3 are set in unit both ends bottom, two return air inlets 4 are set in each 3 two sides of unit blasting air mouth,
Every unit supplies 2 unit blasting air mouths, 4 return air inlets.2 air-conditioner sets 1 are arranged in each rail vehicle, are arranged in roof
At length direction 1/4,3/4, the bottom that unit both ends are set due to sending air port back to, corresponding roof its length direction 1/8,
3/8, there is roof air outlet 6 at 5/8,7/8, greatly reduce air supplying distance, air supply velocity, unit static pressure in air delivery duct 5
And air-supply noise, equally reduce return air wind speed, return air noise.
Referring to Fig. 5-Fig. 6, treated air by unit blasting air mouth and roof air outlet 6 is sent into car by air-conditioner set
In air delivery duct 5, then pass through the feeding of supply grille 7 guest room below air delivery duct.Portion of air passes through back as return air in guest room
The cavity that style grid 8 and air delivery duct 5 and vehicle other component are formed enters air-conditioner set return air inlet 4, enters back into air-conditioner set 1
It is recycled.
