Definitions

  • the invention relates to an air conditioning system for cooling and / or heating for a vehicle, in particular an on-roof air conditioning system, with a housing. Furthermore, the invention relates to a vehicle with such an air conditioner.
  • Such air conditioners may include a housing having a shaping structure made of a foamed plastic to reduce weight.
  • the reduced weight on the roof has a particularly favorable influence on the driving behavior of the vehicle.
  • foamed plastics have a relatively low stability, so that in addition a support structure is provided, which is integrated into the material of the shaping structure.
  • EP 2 061 666 B1 an air conditioning and / or heating system for vehicles is known, in which the housing contains a deposit made of a more stable material than foamed plastic in the foamed plastic.
  • the present invention has for its object to reduce manufacturing and / or disposal costs of an air conditioner.
  • the invention is based on the general idea that it is sufficient that the shaping structure is held by the support structure, without being enclosed by the shaping structure. It is expedient that the housing has a shaping structure and a support structure which are separated are formed from each other. On the one hand, the recycling of the housing of the air conditioning is easier because the shaping structure and the support structure can be separated from each other, so that they can be recycled sorted. On the other hand, the shaping structure can be used unchanged for various applications, in particular for use on different vehicles. Only the support structure must be adapted, which is possible in a simple manner. In the prior art, where the support structure is formed by inserts in the forming structure, it may be necessary to adjust the forming mold mold when the support structure is modified. In contrast, in the solution according to the invention, the shaping structure and in particular the shaping tools for the shaping structure do not have to be adapted, since adaptation to different vehicle types is possible via the supporting structure alone, which is formed separately from the shaping structure.
  • the shaping structure comprises foamed plastic, for example expanded polypropylene (EPP).

  • the shaping structure has at least one lower part and at least one upper part, between which at least one component of the air conditioning system is arranged. The fact that the shaping structure is formed in two parts, the components of the air conditioner, which are accommodated in the housing, can be mounted very easily.
  • At least one lower part and the at least one upper part are detachably connected to one another, in particular by means of screws, clamps and / or tension straps. In this way, the housing of the air conditioner after closing, for example, for maintenance purposes, be reopened.
  • the at least one lower part and the at least one upper part of the shaping structure are held together by a hood, which is connected to the support structure.
  • the hood holds the upper part on the lower part and rests on the upper part over a large area, so that the load on the upper part or the lower part is not punctiform but planar, whereby damage to the upper part and / or the lower part can be avoided.
  • a further advantageous possibility provides that the support structure holds the shaping structure by positive engagement at a site, in particular on a roof of the vehicle. Thereby, a releasable connection between the support structure and the shaping structure can be achieved, whereby the maintenance of the air conditioner is simplified. Furthermore, the support structure, the stability of the shaping structure can be increased when the support structure is applied, for example, over a larger area of the shaping structure.
  • the support structure a plurality of carriers, which may preferably have an L-shaped or C-shaped cross-section.
  • the carrier can be designed as sheet metal body, which are bent once or twice, or as a profile body, which are formed for example by L-profiles or by C-profiles.
  • the fact that the support structure has a plurality of separate, profiled carrier, it has a high rigidity at a relatively low weight. Thus, the weight of the air conditioner can be further reduced.
  • the support structure comprises metal and / or solid plastic.
  • Such materials have a high strength and rigidity over foamed plastics, so that they are particularly well suited for the support structure.
  • the support structure surrounds the shaping structure.
  • the shaping structure can be kept particularly secure.
  • this also further improves the stability of the housing of the air conditioning system.
  • the above object is achieved by a vehicle having an air conditioner as described above, wherein the air conditioner is disposed on a roof of the vehicle.
  • the advantages of the air conditioning system are thus transferred to the vehicle, to the above description of which reference is made.
  • the weight reduction of the air conditioner causes the driving behavior of the vehicle, for example in curves, improved.
  • the center of gravity of the vehicle can be lowered, whereby the inclination of the vehicle can be reduced when cornering.
  • a particularly advantageous alternative provides that the air conditioner is held by the support structure on the roof of the vehicle, in particular by positive engagement.
  • the shaping structure of the air conditioning system can be particularly easily and inexpensively designed, since this does not have to absorb holding forces.

  • the air conditioner 12 is arranged on a roof 14 of the vehicle 10.
  • the vehicle 10 may in particular be a bus, minibus or a train, with which passengers are transported, for which an interior of the vehicle 10 is to be conditioned.
  • the air conditioner 12 has a housing 16 in which components of the air conditioner 12 are received.
  • a heat exchanger 18 and a fan 20 are arranged in the housing 16.
  • 16 flow channels 22 are formed in the housing, through which fresh air and / or circulating air can be passed through the heat exchanger 18 in order to blow them through a fan 20 in the interior of the vehicle 10 can.
  • the housing 16 has a shaping structure 24 which is designed to accommodate the components of the air conditioning system 12, in particular the heat exchanger 18 and the blower 20. Further, the shaping structure 24 forms the flow channels 22 which, for example, direct air from a fresh air opening 26 or a recirculating air opening 28 to the heat exchanger 18 and from the heat exchanger 18 via a fan 20 to an exhaust opening 30.
  • this foamed plastic for example expanded polypropylene (EPP).
  • EPP expanded polypropylene
  • foamed plastics have a low weight and are therefore particularly suitable as a filler. Due to the thus formed air conditioning 12, the weight arranged on the roof 14 of the vehicle 10 can be reduced, whereby the center of gravity of the vehicle 10 can be lowered.
  • the shaping structure 24 is formed in particular exclusively from foamed plastic. Thus, the weight of the air conditioner 12 can be further reduced.
  • the shaping structure 24 has an upper part 32 and a lower part 34 into which the components of the air conditioning system 12 are inserted. For example, two heat exchangers 18 and four blowers 20 are first inserted into the lower part 34 and provided with corresponding connections.
  • the top 32 can be placed on the base 34 to hold the components of the air conditioner 12 in place. It is also possible to first use the components of the air conditioning system 12 in the upper part 32 and then to place the lower part 34 on the upper part 32, so that the air conditioner 12 is mounted on the head.
  • the assembly is accordingly simplified.
  • the upper part 32 can be fastened to the lower part 34, for example by means of screws, clamps or straps.
  • the connection between upper part 32 and lower part 34 is detachable, so that, for example, for maintenance purposes, the housing 16 of the air conditioner 12 can be opened to expose the components of the air conditioner 12.
  • a hood 36 may be provided, with which the upper part 32 can be held on the lower part 34.
  • the hood 36 in this case has a shape adapted to the shape of the upper part 32, so that the hood 36 rests against the upper part 32 over a large area. In this way, the holding forces needed to hold the top 32 on the base 34 and which are needed to hold the housing 16 together with the components received therein can be distributed over a larger area, so that the relatively low strength of the foamed plastic of the shaping structure 24 is sufficient to avoid damage.
  • the hood 36 is made of a material which has a higher strength than foamed plastic, in particular a higher tensile strength.
  • the hood 36 is made of solid plastic.
  • the housing 16 of the air conditioning system 12 has a support structure 38 with which the housing 16 is held on the vehicle 10, in particular on the roof 14 of the vehicle 10.

  • the shaping structure 24 is held directly or indirectly by form fit on the support structure 38.
  • the support structure 38 may be formed, for example, frame-shaped, wherein the frame 40 is formed of a plurality of carriers.
  • the frame 40 has four beams that form a rectangle and surround the shaping structure 24.
  • the carriers may advantageously be designed as C-carriers, so that they have a C-shaped cross-section.
  • L-carrier conceivable, which have an L-shaped cross-section.

  • the air conditioner 12 in this case has two heat exchangers 18, that is to say a heat exchanger 18 for two fans 20.
  • the heat exchangers 18 absorb heat from the air flowing through the heat exchanger 18 and release the heat to a refrigerant 42. In this way the air is cooled.
  • an evaporator 44 of the heat cycle of the air conditioner 12 is integrated.

Thus, this solution represents an advantageous compromise, which makes the best use of the available space.
  • the air conditioner 12 When cooling the air flowing through the heat exchanger 18, condensate, which is reflected in the heat exchanger 18 is formed. For this reason, the air conditioner 12 is equipped with Kondensatsammei drivingen 46, which collects the condensate, so that the condensate can be selectively discharged. It is provided per heat exchanger 18 at least one Kondensatsammei driving 46. Each Kondensatsammei driving 46 derives the collected condensate via at least one, for example two, condensate drain line 48. Since the condensate collection means 46 must be arranged below the heat exchanger 18 in gravity, the condensate collecting means 46 are only briefly above the roof 14 of the vehicle 10.
  • the condensate drain line 48 from the Kondensatsammei Rhein 46 not proceed directly downwards, but runs first substantially parallel to the roof 14 of the vehicle 10 to one side of the vehicle 10. From there, the condensate drain lines 48 extend downwardly.
  • the two heat exchangers 18 and the associated Kondensatsammei driving 46 are each arranged off-center of the vehicle, so that of each Kondensatsammei driving 46, the condensate drain lines 48 each extend to the same side of the vehicle. As a result, when the vehicle 10 is tilted about a vehicle longitudinal axis, the condensate from one of the condensate collection devices 46 can not drain.
  • the air conditioner 12 has a condensate line 50, which connects the condensate collecting means 46 of the two heat exchangers 18, so that when the vehicle 10 is inclined at an angle about the longitudinal axis, the condensate from both Kondensatsammei worn 46th can run in the same direction.
