Air-conditioning arrangement for an interior of a vehicle
An air-conditioning arrangement for an interior of a vehicle, with an air-conditioning unit, for providing air-conditioned interior air, and a cooling assembly, which is arranged in the interior. The cooling assembly has a refrigeration circuit, which, for removing heat from a refrigerant of the refrigeration circuit, has a heat exchanger, which is exposed to the interior air. The heat exchanger is spatially divided into a hot-gas section and a low-temperature section. The interior air that is taken in for the heat removal by the heat exchanger is divided into an outgoing-air component and a recirculating-air component. The low-temperature section of the exchanger is exposed to the recirculating-air component of the interior air and the hot-gas section of the heat exchanger is exposed to the outgoing-air component of the interior air.
1. An air-conditioning arrangement for an interior of a vehicle, the air-conditioning arrangement comprising:
an air conditioner providing air-conditioned interior air;
a cooling assembly disposed in the interior, said cooling assembly having a refrigeration circuit with a heat exchanger for removing heat from a refrigerant of said refrigeration circuit;
said heat exchanger being spatially divided into a first section and a second section;
wherein the interior air that is drawn in for heat removal from said heat exchanger is output from said heat exchanger as an outgoing-air component and a recirculating-air component; and
wherein said second section of said heat exchanger is exposed to the recirculating-air component of the interior air and said first section of said heat exchanger is exposed to the outgoing-air component of the interior air.
2. The air-conditioning arrangement according to claim 1 , wherein said heat exchanger is a cross-counterflow heat exchanger.
3. The air-conditioning arrangement according to claim 1 , wherein said first section and said second section of said heat exchanger directly adjoin one another.
4. The air-conditioning arrangement according to claim 1 , wherein said first section and said second section of said heat exchanger are spatially separated from one another.
5. The air-conditioning arrangement according to claim 1 , which comprises:
a fan assigned to said first section of said heat exchanger for drawing in the outgoing-air component from the interior air into said first section; and
a fan assigned to said second section of said heat exchanger for drawing in the recirculating-air component from the interior air into said second section.
6. The air-conditioning arrangement according to claim 1 , which comprises an air distribution device arranged between said first section and said second section and configured to divide the interior air drawn in into the outgoing-air component and the recirculating-air component.
7. The air-conditioning arrangement according to claim 1 , wherein a volume flow of the outgoing-air component is smaller than a volume flow of the recirculating-air component.
8. The air-conditioning arrangement according to claim 7 , wherein the volume flow of the outgoing-air component that is drawn into said first section of said heat exchanger is less than 40% of a volume flow of the interior air that is drawn in.
9. The air-conditioning arrangement according to claim 1 , wherein said cooling assembly is a gas cooler and each of said first section and said second section has a substantially rectangular design.
