Air after air-conditioner set 4 processes enters four air-supply boxes 10 respectively after four air outlets 16, send in supply air duct 22 from the air outlet 11 of four air-supply boxes 10 again, cold air is finally sent in guest room from the bar gap-like car inner wind outlet 12 between side top board 20 and side heading tape lamp body 29 and the bar gap-like car inner wind outlet 36 side top board 20, simultaneously, air in car enters return airway 30 by return air inlet 13 in two cars on middle top board 21, finally enter again in air-conditioner set 4 and carry out interchange of heat with evaporator, complete refrigerating cycle.The air-supply of air-conditioner set 4 is transported in guest room along car body longitudinal length direction by the present embodiment, without air-supply dead angle, solve the problem that in guest room, longitudinally air-supply is uneven, adopt from roof both sides Lateral supply mode simultaneously, make air current composition reasonable, can avoid blowing and directly blow the sense of discomfort that human body causes, improve the air-conditioning effect difference problem of light section vehicle in summer, improve traveling comfort in car.
The present embodiment, the in-built head room of Appropriate application, top board 21 in utilization, cavity between the steel structure of car body 23 at side top board 20 and top is as supply air duct 22, in addition supply air duct is installed no longer separately, solve top, guest room and cannot arrange supply air duct problem, eliminate independent air channel structure simultaneously, alleviate weight and provide cost savings, and, while guarantee air output, the height between in-built top board and steel structure of car body 23 can be reduced, height in roof above top board 21 is reduced to 120mm by 220mm of the prior art, and then reduce the height of car load, meet the requirement of vehicle gauge.In addition, also not by the restriction of air-conditioner set 4 installing space, the air-supply homogeneity of whole guest room longitudinal space is ensured.
The air outlet of air-conditioner set and return air inlet adopt windproof, waterproof sealing structure; ensure that nothing is leaked out, drainage; easy when being installed on car, reliable; without the need to special instrument and complicated operating sequence; air-conditioner set 4 operationally; condensate water and rainwater all can successfully be discharged from drain hose, favorable sealing property, protect without condensing water leakage and water droplet blowout and drip.
As shown in Figure 10, in the present embodiment, around the air outlet on air-conditioner set 2 diapire 4, first circular groove 47 is being set, in the first circular groove 47, stick with glue knot installation one enclose the first packing seal 48, first circular groove 47, opening downly be arranged on the diapire 53 of air-conditioner set 4, the first packing seal 48 is identical with the shape of the first circular groove 47.Equally, opening on steel structure of car body 23 is provided with second circular groove 49, in the second circular groove 49, stick with glue knot installation one enclose the second packing seal 50, on the opening up upper surface being arranged on steel structure of car body 23 of second circular groove 49, the second packing seal 50 is identical with the shape of the second circular groove 49.
First circular groove 47 and the second circular groove 49 stagger setting mutually, after installation, the second packing seal 50 in side compressing second circular groove 49 of the first circular groove 47, simultaneously, the first packing seal 48 in side compressing first circular groove 47 of the second circular groove 49, form inner ring and outer ring two seals, achieve being tightly connected between air outlet and opening, and ensure the bubble-tight requirements at the higher level of high speed railway car.
In order to avoid the metal side of the first circular groove 47 and the second circular groove 49 damages the first packing seal 48 and the second packing seal 50 when compressing, in the present embodiment, on the side compressing corresponding second packing seal 50, one deck first sealing joint strip 51 is wrapped up at the first circular groove 47, on the side compressing corresponding first packing seal 48, one deck second sealing joint strip 52 is wrapped up at the second circular groove 47, when compressing, utilize the first sealing joint strip 51, second sealing joint strip 52 and the first packing seal 48, second packing seal 50 contacts, avoid metal directly with the first packing seal 48, second packing seal 50 contacts.
In the present embodiment, preferably two sides of the first circular groove 47 and the second circular groove 49 adopt length limit structure, long limit wherein compresses the first packing seal 48 in the first corresponding circular groove 47 and the second circular groove 49 as annular protrusion and the second packing seal 50 realizes sealing, so more be conducive to installing, and it is also more to compress deflection, press seal performance improves further.Utilize the first circular groove 47 and the width of the second circular groove 49 and the length press seal on long limit, fully can absorb the installation error in the vertical upper and horizontal direction that produces when actual existing car is installed, make mounting and adjusting more convenient, raising installation effectiveness.
First circular groove 47 and the second circular groove 49 adopt channel-section steel or aluminium alloy extrusions, on the diapire being fixedly welded on air-conditioner set 4 respectively and steel structure of car body 23, easy for installation, and can ensure sealing property.
Embodiment two:
Be with embodiment one difference, between middle top board 21 and steel structure of car body 23, along length over ends of body direction, two longitudinal beam (not shown)s are installed, side top board 20 superjacent air space of both sides is separated into out by two longitudinal beams, form two independently between the head space of side, only utilize space above side top board 20 as supply air duct 22, four air outlets 16 of both sides are communicated with the supply air duct 22 of position, top, both sides respectively.Longitudinal beam can not be arranged separately, directly utilizes two roof mounting rails, realizes sealing when roof mounting rail is fixedly connected with top board skeleton 24 by structures such as packing seals, is separated out the space on top, two sides.
As mentioned above, plan content given by reference to the accompanying drawings, can derive similar technical scheme.In every case be the content not departing from technical solutions of the utility model, any simple modification done above embodiment according to technical spirit of the present utility model, equivalent variations and modification, all still belong in the scope of technical solutions of the utility model.
