Abstract

The invention relates to an air conditioning system for conditioning the air of a passenger compartment of a motor vehicle, including an outlet section for diverting at least a portion of an air-mass flow circulating in the air conditioning system into the environment of the motor vehicle, a housing for directing the air-mass flow, wherein at least one fan for conveying the air-mass flow is designed within the housing, as well as a coolant circuit for tempering components of the motor vehicle, in particular, components of a power train, having a coolant-air-heat exchanger for transferring heat from the coolant to an air-mass flow.

First claim

The invention claimed is:

1. An air conditioning system for conditioning air of a passenger compartment of a motor vehicle comprising:
a housing including a first flow path, a first flow duct, and a second flow duct, the first flow duct including a first fan and the second flow duct including a second fan, the first fan and the second fan configured to convey air through the housing;
a refrigerant circuit including an evaporator disposed in the first flow duct and a condenser disposed in the second flow duct;
an outlet section in fluid communication with the housing and configured to receive at least a portion of the air flowing through the housing and convey the portion of the air to the environment; and
a coolant-air-heat exchanger disposed in the first flow path, the coolant-air-heat exchanger configured to provide heat exchange communication between the air flowing through the first flow path and a coolant flowing through a coolant circuit of the motor vehicle, the coolant circuit configured to temper components of the motor vehicle, wherein the coolant-air-heat exchanger is disposed upstream from the first fan and the second fan with respect to a direction of a flow of the air through the housing.

2. The air conditioning system of claim 1 , wherein the first fan is configured to convey the air through the first flow duct and the second fan is configured to convey the air through the second flow duct.

3. The air conditioning system of claim 1 , wherein the outlet section is configured as an exhaust air duct formed in the housing.

4. The air conditioning system of claim 1 , wherein the outlet section includes an air deflector disposed therein, the air deflector selectively opening and closing the outlet section.

5. An air conditioning system for conditioning the air of a passenger compartment of a motor vehicle comprising:
a housing having a first flow path, a first flow duct, and a second flow duct, the first flow duct including a first fan and the second flow duct including a second fan, the first fan and the second fan configured to convey air through the housing;
a refrigerant circuit including an evaporator disposed in the first flow duct and a condenser disposed in the second flow duct; and
a coolant-air-heat exchanger disposed in the first flow path, the coolant-air-heat exchanger configured to provide heat exchange communication between the air and a coolant flowing through a coolant circuit of the motor vehicle, the coolant circuit configured to temper components of the motor vehicle, wherein the coolant-air-heat exchanger is disposed upstream from the first fan and the second fan with respect to a direction of a flow of the air through the housing.

6. The air conditioning system of claim 5 , wherein the first flow path includes a first fresh intake duct, a second fresh intake duct, and a circulating air intake duct formed therein, each of the first fresh intake duct, the second fresh intake duct, and the circulating air intake duct configured to convey the air therethrough, the first fresh intake duct and the second fresh intake duct receiving the air from the environment, and the circulating air duct receiving the air from the passenger compartment of the motor vehicle.

7. The air conditioning system of claim 6 , wherein the coolant-air-heat exchanger is disposed in the circulating air intake duct.

8. The air conditioning system of claim 5 , wherein the air conditioning system is configured for a refrigerant unit operation, a heat pump operation, and a reheating operation of the passenger compartment of the motor vehicle.

9. The air conditioning system of claim 5 , wherein each of the first flow duct and the second flow duct receive the air from at least one of the environment and the passenger compartment.

10. The air conditioning system of claim 5 , wherein the second fan is independently operable from the first fan, the first fan conveying the air through the first flow duct and the second fan conveying the air through the second flow duct.

11. The air conditioning system of claim 5 , wherein the housing includes a partition disposed therein, the partition separating the first flow duct from the second flow duct.

12. The air conditioning system of claim 11 , wherein a flow path is formed through the partition and provides fluid communication between the first flow duct and a portion of the condenser.

13. The air conditioning system of claim 12 , wherein the flow path includes a pair of air baffles and a pair of air deflectors, the pair of air baffles cooperating with the pair of air deflectors to guide the air flowing through the first flow duct through the portion of the condenser.

14. The air conditioning system of claim 1 , wherein the housing includes a second flow path and a third flow path, the second flow path defined by a first fresh air intake duct, the third flow path defined by a second fresh air intake duct, and the first flow path defined by a circulating air intake duct, each of the first fresh air intake duct, the second fresh air intake duct, and the circulating air intake duct configured to convey the air therethrough, the first air fresh intake duct and the second fresh air intake duct receiving the air from the environment, and the circulating air duct receiving the air from the passenger compartment of the motor vehicle, wherein the coolant-air-heat exchanger is disposed in the circulating air intake duct.

15. The air conditioning system of claim 14 , wherein the circulating air duct branches into a first subpath and a second subpath, the first subpath and the first fresh air intake duct converging into a first fan flow path, and the second subpath and the second fresh air intake duct converging into a second fan flow path.

16. The air conditioning system of claim 15 , wherein a first mixing zone is formed at a convergence of the first subpath with the first fresh air intake duct and the circulating air intake duct, wherein a second mixing zone is formed at a convergence of the second subpath with the second fresh air intake duct and the circulating air intake duct, and wherein a first flap is disposed in the first mixing zone and a second flap is disposed in the second mixing zone.
