Abstract

Abstract: Defrosting effects of windshield is very important for vehicle driving safety and comfort in winter. Through CFD simulation and experiments, this paper aims at studying the effects of outlet duct structure, in particular, the impact angle, i.e. the inclined angle of outlet grid relative to windshield, on the defrosting performance of a sedan under development and equipped with traditional engine or pure electric system. The defrosting effects with different impact angles and temperature rise patterns are compared, verifying the effectiveness of structural modification

Key words: automotive air conditioner, defrosting, duct structure
