Abstract

A climate control system having a housing with an air inlet, a cooling element for providing cooled air, a heating element located downstream of the cooling element, a cold air duct for directing cooled air located downstream, a bypass duct for directing cooled air located downstream of the cooling element, a hot air duct for directing heated air, a first mixing chamber for mixing cooled air from the cold air duct and heated air from the hot air duct into blended air, a second mixing chamber located downstream of the bypass duct and downstream of the first mixing chamber for mixing cooled air from the bypass duct and blended air from the first mixing chamber, an air outlet located downstream of the second mixing chamber for delivering air to a passenger compartment, and an air deflector device is located downstream of the bypass duct.

First claim

What is claimed is:

1 . A climate control system comprising:
a housing with an air inlet; a cooling element providing cooled air; a heating element providing heated air, the heating element being located downstream of the cooling element in the housing; a cold air duct directing cooled air located downstream of the cooling element; a bypass duct directing cooled air located downstream of the cooling element; a hot air duct directing heated air located downstream of the heating element; a first mixing chamber located downstream of the cold air duct and downstream of the hot air duct for mixing cooled air from the cold air duct and heated air from the hot air duct into blended air; a second mixing chamber located downstream of the bypass duct and downstream of the first mixing chamber for mixing cooled air from the bypass duct and blended air from the first mixing chamber; an air outlet located downstream of the second mixing chamber for delivering air to a passenger compartment; and an air deflector device arranged downstream of the bypass duct.

2 . The climate control system according to claim 1 , wherein the bypass duct has a downstream section, and wherein the air deflector device extends into the downstream section of the bypass duct.

3 . The climate control system according to claim 1 , wherein the cold air duct has a cold air regulating element, and/or wherein the hot air duct has a hot air regulating element, and/or wherein a blended air regulating element is located in the first mixing chamber.

4 . The climate control system according to claim 1 , wherein the bypass duct has a bypass regulating element.

5 . The climate control system according to claim 1 , wherein a blended air outlet control element is located at a downstream position of the first mixing chamber.

6 . The climate control system according to claim 1 , wherein the air outlet has a plurality of air outlet regions.

7 . The climate control system according to claim 6 , wherein the air deflector device forms a duct or a plurality of ducts.

8 . The climate control system according to claim 7 , wherein at least one duct of the air deflector device is allocated to at least one air outlet region.

9 . The climate control system according to claim 7 , wherein a plurality of ducts of the air deflector device are arranged next to one another and/or are arranged horizontally or vertically adjacent to one another.

10 . The climate control system according to claim 1 , wherein the housing of the climate control system has a defrost duct that delivers defrost air to a defrost outlet that is located in an upper position of the housing.

11 . The climate control system according to claim 7 , wherein the plurality of ducts have first ducts and second ducts, and the first ducts and the second ducts are arranged to run past the defrost duct on different sides.

12 . The climate control system according to claim 1 , wherein the ducts are routed in a curve around the defrost duct.
