In this study, Experiments on compartment air flow are carried out on condition of forced ventilation and natural ventilation by using the laser visualization method. Targeted models are HKMC’s vehicles and their competitive ones. Experiments on 4door vehicle have performed changing and improving influence factor of ventilation performance and evaluated resulting values; Fogging generation performance, Defrosting performance and compartment static pressure. As a result of laser visualization, ‘air extractor grille’ and ‘rear package tray & rear glass gap’ have proven to be major factor deciding compartment air flow. Also, in case that air extractor grille was chosen among improvement factors and adopted two ones, we could achieve best results in tests on fogging generation performance, Defrosting performance, Compartment static pressure
