Abstract

The relevant parameters in the process of parking ventilation were studied to obtain the parameters that are helpful to enhance the effect of parking ventilation． Firstly，a model experiment was used to verify the accuracy of hot soak and ventilation cooling simulation． Then，under the conditions of model experiment，the cabin hot soak and ventilation process was simulated，and the driver compartment cooling effects under different parked car venti- lation parameters were compared． The results show that，after hot soak，the cooling effect is obvious in the first 3 minutes，and the increase of air volume is helpful for cooling，but the effect is not obvious when the air speed exceeds 250 m3 /h． In addition，adjusting the air volume distribution ratio and increasing the air flow with upward deflection can enhance the cooling effect．

Key words： hot soak; driver compartment cooling; parked car ventilation; ventilation parameter
