Abstract

An assembly for an air conditioning system may include an air filter for filtering drawn-in fresh air. The air filter may be arranged in a fresh air path and may separate a raw side from a clean side of the fresh air path. A water path for discharging water separated from the fresh air may be disposed at the raw side of the air filter. The water path may include a water filter for filtering the separated water. The water filter may separate a raw side from a clean side of the water path.

First claim

The invention claimed is:

1. An assembly for an air conditioning system, comprising:
an air filter for filtering drawn-in fresh air, the air filter arranged in a fresh air path and separates a raw side from a clean side of the fresh air path,
a water path for discharging water separated from the fresh air disposed at the raw side of the air filter,
wherein the water path includes a water filter for filtering the separated water, the water filter separating a raw side from a clean side of the water path.

2. The assembly according to claim 1 , wherein the water path includes a water box for collecting and discharging the separated water, wherein the water box is arranged at least one of at the raw side of the fresh air path and in the raw side of the fresh air path.

3. The assembly according to claim 2 , wherein the water filter is arranged in the water box.

4. The assembly according to claim 2 , wherein the water box is arranged at a lower lateral end of the air filter and has a water inlet opening open upwardly in a direction of the air filter.

5. The assembly according to claim 4 , wherein the air filter includes a filter body composed of a filter material and has at least one end plate arranged laterally on the filter body, wherein the water box is formed integrally on the at least one end plate of the air filter.

6. The assembly according to claim 3 , wherein the water filter includes a filling of a filter material, wherein the filling is at least one of filled directly into the water box, filled into a bag arranged in the water box and introduced into the water box as at least one of a shaped non-woven material and a filter foam.

7. The assembly according to claim 3 , wherein the water filter includes a non-woven material cover, which covers a water inlet opening of the water box.

8. The assembly according to claim 3 , wherein:
the water box is elongated and has at a longitudinal end a water outlet opening for discharging filtered water, and
the water box has a base defining a sloped profile sloping in a direction of the water outlet opening.

9. The assembly according to claim 3 , wherein the air filter and the water filter are arranged such that a filter material of the air filter and a filter material of the water filter do not touch each other.

10. The assembly according to claim 3 , wherein the air filter and the water filter form an exchangeable installation unit for removably arranging on a housing.

11. The assembly according to claim 3 , wherein at least one of:
the air filter has a filter material including an adsorption element, and
the water filter has a filter material including an adsorption element.

12. The assembly according to claim 2 , wherein the water filter is arranged in the water path downstream of the water box.

13. An air conditioning system for a vehicle, comprising:
a fresh air path for directing a fresh air stream,
a drainage arrangement for separating water entrained in the fresh air stream, the drainage arrangement including a water path for discharging the water from the fresh air path, and
an assembly including an air filter for filtering the fresh air stream and a water filter for filtering the separated water, wherein the air filter is arranged in the fresh air path and separates a raw side from a clean side in the fresh air path, and the water filter is arranged in the water path and separates a raw side from a clean side in the water path.

14. The air conditioning system according to claim 13 , further comprising an air cooler arranged downstream the air filter in the fresh air path for cooling the fresh air stream, wherein the air cooler includes a condensate discharge fluidically connected to the clean side of the water path.

15. The air conditioning system according to claim 13 , wherein the air filter includes a water box arranged at the raw side of the fresh air path and in fluid communication with the water path.

16. The air conditioning system according to claim 15 , wherein the water filter is arranged in the water box.

17. The air conditioning system according to claim 16 , wherein the water filter includes a non-woven material cover which covers a water inlet opening of the water box.

18. The air conditioning system according to claim 17 , wherein the water box includes a base opposite the water inlet opening and a longitudinal end having a water outlet opening for discharging the separated water, wherein the base defines a profile sloping in a direction of the water outlet opening.

19. The air conditioning system according to claim 13 , wherein at least one of:
the air filter includes a filter material having an adsorption element; and
the water filter includes a filter material including an adsorption element.

20. An assembly for an air conditioning system of a vehicle, comprising:
an air filter for filtering a fresh air stream, the air filter arranged in a fresh air path and separates a raw side of the fresh air path from a clean side;
a water path for discharging separated water from the fresh air steam disposed at the raw side of the air filter;
a water box in communication with the water path and disposed at the raw side of the fresh air path;
a water filter arranged in the water box and separating a raw side of the water path from a clean side, the water filter including a non-woven material cover; wherein the water box is arranged at a lower lateral end of the air filter and has an inlet opening for receiving the separated water, the water box including a base opposite the water inlet opening and a longitudinal end having a water outlet opening for discharging the separated water, wherein the base defines a profile sloping in a direction of the water outlet opening; and
wherein the non-woven material cover of the water filter covers the water inlet opening.
