Abstract

Example embodiments relate to an air conditioning unit for installation on a roof, including a housing, an indoor air distributor, and two frame units. The two frame units are of identical design and each have a first side and a second side. In an installed state, the two frame units are arranged between the housing and the indoor air distributor and serve as an upper frame unit and a lower frame unit, respectively. The first sides face each other, the second side of the upper frame unit faces the housing, and the second side of the lower frame unit faces the indoor air distributor.

First claim

The invention claimed is:

1. An air conditioning unit for installation on a roof, comprising:
a housing, an indoor air distributor, and two frame units, wherein:
the two frame units are of identical design,
each frame unit having a first side and a second side,
in an installed state, the two frame units are arranged between the housing and the indoor air distributor, and one frame unit serves as an upper frame unit and the other frame unit serves as a lower frame unit, and
in the installed state, the first sides of the two frame units face each other, and the second side of the upper frame unit faces the housing and the second side of the lower frame unit faces the indoor air distributor.

2. The air conditioning unit according to claim 1 , wherein the frame units each have an inner edge which each encloses an inner recess.

3. The air conditioning unit according to claim 1 ,
wherein the frame units each have a plurality of mounting recesses for receiving mounting elements, and
wherein at least one mounting recess allows an inserted mounting element to be fixed in place.

4. The air conditioning unit according to claim 3 , wherein the fixing is obtained by a form fit and/or force fit between the mounting recess and the mounting element.

5. The air conditioning unit according to claim 3 , wherein the fixing is obtained in that a clamping hook is associated with the mounting recess.

6. The air conditioning unit according to claim 3 , wherein at least one mounting recess is shaped as a through-recess, which has a geometry on the first side of the frame unit that differs from the geometry on the second side of the frame unit.

7. The air conditioning unit according to claim 1 , wherein the frame units each include at least one stiffening member on at least one side.

8. The air conditioning unit according to claim 7 ,
wherein a plurality of stiffening members are provided, and
wherein the stiffening members are material accumulations having a substantially identical geometry.

9. The air conditioning unit according to claim 7 , wherein the stiffening member is configured as an at least partially annular enclosure of a mounting recess with webs adjoining in a star shape.

10. The air conditioning unit according to claim 7 , wherein the stiffening member is configured as a crossbar.

11. The air conditioning unit according to claim 1 , wherein the frame units each include at least one depression for a sealing component on one side.

12. The air conditioning unit according to claim 1 , wherein on one side, the frame units each include at least one sealing structure which is in the form of at least one raised portion.

13. The air conditioning unit according to claim 12 , wherein on an outer face of the sealing structure at least one clearance surface is provided, which is open toward the outside.

14. The air conditioning unit according to claim 1 , wherein the frame units each include at least one removable dome on one side.

15. The air conditioning unit according to claim 1 , wherein on one side, the frame units each include at least one indicator.

16. The air conditioning unit according to claim 1 , wherein the frame units each are one-piece injection-molded plastic components.

17. The air conditioning unit according to claim 12 , wherein on an outer face of the sealing structure at least one clearance surface is provided, which is open toward the outside and inclined thereof.
