Abstract

The invention relates to an air-conditioning system for a motor vehicle. According to the invention, an accessory drive is provided for supplying power to the air-conditioning system, particularly to an auxiliary air-conditioning system for a motor vehicle. The accessory drive generates heat and/or mechanical power and/or electrical power.

Claims

1. A power supply system for a motor vehicle, in particular with an air-conditioning system and/or auxiliary air-conditioning system, characterized by an auxiliary drive for supply of power to at least one vehicle component, in particular the air-conditioning system, the auxiliary drive generating heat and/or mechanical energy and/or electrical energy.

2. The power supply system as claimed in claim 1, characterized in that the auxiliary drive generates the heat by means of a burner for heating a working fluid.

3. The power supply system as claimed in claim 1, characterized in that the heated working fluid is used for preheating a motor vehicle engine and/or for heating a vehicle interior.

4. The power supply system as claimed in claim 3, characterized in that, to heat the vehicle interior, the working fluid is conducted through a radiator of an auxiliary air-conditioning system.

5. The power supply system as claimed in claim 4, characterized in that the radiator is part of a heating circuit already present in the motor vehicle.

6. The power supply system as claimed in claim 1, characterized in that the auxiliary drive generates the electrical energy by means of a generator.

7. The power supply system as claimed in claim 1, characterized in that, to cool a vehicle interior, the auxiliary drive supplies power to a cooling circuit of the auxiliary air-conditioning system with an evaporator, with a compressor and with a condenser.

8. The power supply system as claimed in claim 7, characterized in that the auxiliary drive makes the power for the cooling circuit available in the form of mechanical and/or electrical energy for the compressor.

9. The power supply system as claimed in claim 7, characterized in that the evaporator is part of a refrigerant circuit already present in the motor vehicle.

10. The power supply system as claimed in claim 7, characterized in that the condenser is part of the refrigerant circuit already present in the motor vehicle.

11. The power supply system as claimed in claim 7, characterized in that the compressor is part of the refrigerant circuit already present in the motor vehicle.

12. The power supply system as claimed in claim 11, characterized in that the compressor is driven via a coupling by the motor vehicle engine in normal operation and by the auxiliary drive in auxiliary air-conditioning operation.

13. The power supply system as claimed in claim 10, characterized in that the compressor is driven by the auxiliary drive in normal operation and in auxiliary air-conditioning operation.

14. The power supply system as claimed in claim 3, characterized by an air-conditioning apparatus for the auxiliary air-conditioning system for temperature determination and/or air mixing and/or air distribution for the vehicle interior.

15. The power supply system as claimed in claim 14, characterized in that the air-conditioning apparatus comprises a control unit and/or an operating unit.

16. The power supply system as claimed in claim 14, characterized in that the air-conditioning apparatus is part of an air-conditioning system already installed in the vehicle.

17. The power supply system as claimed in claim 1, characterized in that the auxiliary drive is designed as a fuel cell.

18. The power supply system as claimed in claim 1, characterized in that the auxiliary drive comprises means for the generation of steam, from which the mechanical energy is obtained.

19. The power supply system as claimed in claim 18, characterized in that the steam is generated as a result of the combustion of fuels in a thermal reactor.

20. The power supply system as claimed in claim 1, characterized in that the at least one vehicle component is suitable, in particular alone, for supplying the motor vehicle during the operation and during a standstill of an engine.

21. The power supply system as claimed in claim 1, characterized in that the at least one vehicle component is a heating and/or air-conditioning device, a booster pump, a hydraulic pump, a water pump, a compressed-air compressor, a fan and/or a current generator.
