Résumé

For traditional vehicle, the compressor in air-conditioning system (MC system) is belt-driven by the engine power through the crankshaft. For the idling stop vehicle, the electric power-assisted AIC system is essential for replacing the belt-driven mechanism. In this paper, the saving on fuel economic and performance on energy usage are evaluated for the electric-powered MC system and the design of auxiliary motor is elaborated for the idling-stop vehicle. The result shows that the fuel consumption increases in 14.2% during the idling condition when the compressor of A/C system is driven by engine. For the power-assisted A/C proposed in this paper, however, the fuel consumption would be decreased more than 30% for the vehicle in highway fuel economy cycle (HWFET cycle) developed by the US EPA. In such a condition, the energy saving is achievable and the heat exchange ability in idling stop period is capable for keeping the desired cabin temperature. Besides, by considering the limited space in engine compartment, a blushless DC motor is properly designed and fabricated for the application to the auxiliary power in the A/C system of an idling-stop vehicle.
