42 V Electric Air Conditioning Systems (E-A/CS) for Low Emissions, Architecture, Comfort and Safety of Next Generation Vehicles 2001-01-2500
Electrical Air Conditioning Systems for 42 V vehicles will provide many benefits in terms of Environment protection, car Architecture, cabin Comfort and overall Safety.
E-A/CSystems essentially differ from conventional ones by the use of electrical compressors.
First of all, they will be particularly well adapted to new powertrains, helping to make them more environmentally friendly. Accurate control and high efficiency under the most common thermal conditions will reduce the A/C impact on fuel consumption. Besides, higher sealing integrity will cut emissions of refrigerant during normal operation and maintenance.
Secondly, the use of an electrically driven compressor (EDC) will suppress a belt, and will reduce the packaging constraints. This will help to design new vehicle architectures.
Thirdly, the electrification of air conditioning will allow better thermal comfort. In particular, E-A/C Systems provide a good opportunity for cabin pre-conditioning.
Finally, safety will be improved thanks to better thermal comfort and visibility, and thanks to better mass distribution allowing better crash-test behaviour.
