Reducing soak air temperature inside a car compartment using ventilation fans
Haslinda Mohamed Kamar1, Nazri Kamsah2, Intan Sabariah Sabr3, Md Nor Musa4.
This article presents an investigation on the effects of using ventilation fans on the air
temperature inside a car passenger compartment when the car is parked under the
sun. It was found from a measurement that the air temperature inside the passenger
compartment could raise up to 48°C. Computational fluid dynamics method was
used to develop model of the compartment and carry out flow simulations to predict
the air temperature distribution at 1 pm for two conditions: without ventilation fans
and with ventilation fans. The effects of fan location, number of fans used and fan
airflow velocity were examined. Results of flow simulations show that a 17%
temperature reduction was achieved when two ventilation fans with airflow velocity
of 2.84 m/s were placed at the rear deck. When three fans were used, an additional
3.4% temperature reduction was attained. Placing two ventilation fans at the middle
of the roof also reduced the air temperature by 17%. When four fans were used a
further 4.8% temperature reduction was achieved. Increasing the airflow velocity at
the four fans placed at the roof, from 2.84 m/s to 15.67 m/s, caused only a small
reduction in the air temperature inside the passenger compartment.
