Connection, rhone 9 is made up of aluminium alloy or stainless steel, to mitigate weight.Condensed water and rainwater when air-conditioner set 4 works etc. are
The drainpipe at air-conditioning platform two ends is introduced at from rhone 9, then is finally drained into outside car.
Spool 27 is installed between steel structure of car body 23 and middle top board 21, cable etc. is arranged in spool 27, and spool 27 leads to
Pipe clamp is crossed to be fixed on top board skeleton 24.
Air after the treatment of air-conditioner set 4 by respectively enteing four air-supply boxes 10 after four air outlets 16, then from four
Blow in the feeding supply air duct 22 of air outlet 11 of box 10, cold air bar finally between side top board 20 and side heading tape lamp body 29
In the bar gap-like in-car feeding of air outlet 36 guest room on gap-like in-car air outlet 12 and side top board 20, meanwhile, in-car air leads to
The two in-car return air inlets 13 crossed on top board 21 enter return airway 30, then finally enter to enter with evaporator in air-conditioner set 4
Row heat exchange, completes kind of refrigeration cycle.The air-supply of air-conditioner set 4 is transported to guest room by the present embodiment along car body longitudinal length
It is interior, without air-supply dead angle, inequality of longitudinally being blown in guest room is solved the problems, such as, while using from roof both sides Lateral supply mode, making
Air current composition rationally, ask by the sense of discomfort that air-supply blow-through human body can be avoided to cause, the air-conditioning effect difference for improving summer light section vehicle
Topic, improves in-car comfortableness.
The present embodiment, rationally make use of built-in headroom, the car body steel knot at top board 21, side top board 20 and top in utilization
Cavity between structure 23 as supply air duct 22, no longer independent additionally mounted supply air duct, solving guest room top cannot arrange
Supply air duct problem, while eliminating single air channel structure, alleviates weight and saves cost, and, ensureing to blow
While amount, the height between built-in top board and steel structure of car body 23 can be reduced, the height of the top of top board 21 is by existing in roof
There is the 220mm in technology to be reduced to 120mm, and then reduce the height of vehicle, meet the requirement of vehicle gauge.In addition, also not
Limited by the installing space of air-conditioner set 4, it is ensured that the air-supply uniformity of whole guest room longitudinal space.
Embodiment two：
It is with the difference of embodiment one, in addition to in-car air outlet 12 and 36 is opened up on side top board 20, it is also possible to root
In-car air outlet (not shown) is opened up on middle top board 21 according to being actually needed, the in-car air outlet on middle top board 21 can be by
Multiple little round tube hole compositions, or bar gap-like opening.
Embodiment three：
It is with embodiment one and the difference of embodiment two, it is long along car body between middle top board 21 and steel structure of car body 23
Two longitudinal beam (not shown)s are installed in degree direction, and be separated into out for the superjacent air space of side top board 20 of both sides by two longitudinal beams
Come, between forming two independent side head spaces, merely with the space of the top of side top board 20 as supply air duct 22, four of both sides send
Supply air duct 22 of the air port 16 respectively with both sides top position is connected.Longitudinal beam can not be separately provided, and directly utilize two roofs
Mounting rail, sealing is realized when roof mounting rail is fixedly connected with top board skeleton 24 by structures such as sealing gaskets, is separated out two sides top
Space.
As described above, the plan content with reference to given by accompanying drawing, can derive similar technical scheme.In every case it is not de-
From the content of technical solution of the present invention, any simple modification made to above example according to technical spirit of the invention, etc.
