Abstract

The invention concerns an air conditioning system for conditioning the air of a passenger compartment of a motor vehicle including a housing with a first flow channel and a second flow channel for conducting air and a refrigerant circuit with an evaporator and a condenser. The evaporator is arranged in the first flow channel and the condenser in the second flow channel. The air conditioning system is designed for cooling and heating the passenger compartment and for a reheat operation. The setting of the operating mode is done only via the controlling of air guidance mechanisms. One of the heat exchangers evaporator or condenser is arranged with a part of the heat transfer surface in both the first and the second flow channel.

First claim

What is claimed is:

1. An air conditioning system for cooling, heating, and reheating an air supply for a vehicle comprising:
a housing having a first flow channel and a second flow channel formed therein, the first flow channel configured for receiving a first flow of the air supply and the second flow channel configured for receiving a second flow of the air supply, the first flow channel divided into a first flow channel flow path and a bypass channel;
a partition wall disposed intermediate the first flow channel and the second flow channel, the partition wall separating the first flow channel from the second flow channel wherein the first flow of the air supply is not in fluid communication with the second flow of the air supply within the housing;
a first evaporator disposed in the first flow channel, wherein the first evaporator extends across an entirety of a flow cross-section of the first flow channel, wherein a first end of the first evaporator is disposed adjacent an inner surface of the housing defining a portion of the first flow channel and a second end of the first evaporator is disposed adjacent an inner surface of the partition wall defining a boundary of the first flow channel;
a condenser having a first region and a second region, the first region disposed in the second flow channel and the second region disposed in the first flow channel flow path; and
a plurality of air guidance mechanisms arranged in the housing and cooperating to direct the air supply through at least one of the first flow channel and the second flow channel.

2. The air conditioning system of claim 1 , further comprising a refrigerant circuit, the refrigerant circuit having a compressor and an expansion element in fluid communication with the first evaporator and the condenser.

3. The air conditioning system of claim 2 , wherein the refrigerant circuit further comprises a second evaporator in fluid communication with the first evaporator and the condenser.

4. The air conditioning system of claim 1 , further comprising at least a first fan and a second fan, the first fan in fluid communication with the first flow channel and the second fan in fluid communication with the second flow channel.

5. The air conditioning system of claim 4 , further comprising a first valve disposed downstream of the first fan at an inlet of the first flow channel and a second valve disposed downstream of the second fan at an inlet of the second flow channel.

6. The air conditioning system of claim 4 , wherein the first fan directs the air supply during a heating mode of the air conditioning system and the second fan directs the air supply during a cooling mode of the air conditioning system.

7. The air conditioning system of claim 4 , further comprising a first flow path disposed upstream from the first fan, a second flow path disposed upstream from the second fan, and a third flow path disposed upstream from the first fan and the second fan, the first flow path and the second flow path receiving at least one of air from the vehicle, outside air, and air from the second flow of the air supply through the second channel, the third flow path receiving at least one of the air from the vehicle and the air from the second flow of the air supply through the second channel.

8. The air conditioning system of claim 1 , further comprising a first static air guidance mechanism disposed adjacent and in fluid communication with an inlet of the condenser and a second static air guidance mechanism disposed adjacent and in fluid communication with an outlet of the condenser.

9. The air conditioning system of claim 8 , wherein a first air guidance mechanism of the plurality of air guide mechanisms is disposed upstream from the first static air guidance mechanism with respect to the flow of the air supply and a second air guidance mechanism of the plurality of air guidance mechanisms is disposed downstream from the second static air guidance mechanism with respect to the flow of the air supply.

10. The air conditioning system of claim 8 , wherein the first static air guidance mechanism and the second static air guidance mechanism are formed from a plurality of baffles arranged in parallel to maintain the first flow of the air supply separate from the second flow of the air supply through the condenser, the baffles coupled to each other by transverse struts to form a lattice.

11. The air conditioning system of claim 9 , wherein each of the first air guidance mechanism and the second air guidance mechanism is adapted to cooperate with the first static air guidance mechanism and the second static air guidance mechanism to at least partially allow at least one of the first flow of the supply air and the second flow of the supply air.

12. The air conditioning system of claim 11 , wherein the first air guidance mechanism rotates about a first axis and the second air guidance mechanism rotates about a second axis, the first axis and the second axis are perpendicular to a direction of the flow of the air supply.

13. The air conditioning system of claim 12 , wherein the first axis is disposed at a distance from the first static air guidance mechanism substantially equal to a dimension of the first air guidance mechanism with respect to the direction of the flow of the air supply and the second axis is disposed at a distance from the second static air guidance mechanism substantially equal to a dimension of the second air guidance mechanism with respect to the direction of the flow of the air supply.

14. The air conditioning system of claim 13 , wherein the first static air guidance mechanism has a curvilinear profile corresponding to a radius with respect to the first axis and the second static air guidance mechanism has a curvilinear profile corresponding to a radius with respect to the second axis, the radius with respect to the first axis is substantially equal to the dimension of the first air guidance mechanism and the radius with respect to the second axis is substantially equal to the dimension of the second air guidance mechanism.
