Abstract
urope, passenger cars are responsible for 12% of C O 2 emissions. The European Commission established new regulations to drastically redu ce the emissions from 130g to 95g CO 2 per km between 2015 and 2021. While the automobile i ndustry is looking at different ways to meet those criteria, the presented industry-driven p roject aims at reducing energy consumption by up to 30% of air-conditioning (AC) in passenger c ars with the introduction of a novel system. The current systems reduce the fuel economy to up to 2 0% for gas motors and even more for electric cars. Through Selective Laser Sintering (SLS ) design freedom and short production cycles; the design of the AC casing was drastically opti mized to increase its contact area with incoming air. To further increase the heat exchange t hroughout the system, the thermal conductivity of SLS material was improved by incorpor ation of mineral fillers. The successful implementation of both optimizations led to a CO 2 emission reduction of around 50% for the climate control of passenger cars. Mehr anzeigen
