In the past few years many fatalities have been reported as the result of internal car heat. Problems arise when the temperature in a car cabin is too hot when parked under direct sunlight. The trapped and accumulated heat causes the temperature inside a car to reach up to 36ºC and even up to 50ºC. The objectives of this paper are to study and analyze the behavior of car cabin temperature influenced by ventilation under direct sun exposure. The performance of the proposed mathematical modelling was compared to data collected in real time from the car cabin. The simulation model was used to study the behavior of cabin temperature by investigating the ventilation mass flow rate as its parameter. An experimental result was obtained from measurements on a salon car parked in the direct sun. It is hoped that this study will be able to provide beneficial information for car interior design and material selection in order to improve comfort levels in cars.
