Physiological Responses of the Driver in a Solar Heated Car Cabin

Ilham Bakri, Nilda Nilda, Ahmad Wira Indrawan

 

Abstract:

The aim of this study
was to evaluate the physiological responses of the driver when he or she enters
the vehicle cabin for the first time after the vehicle was in a parking lot.
Eight healthy male students underwent tests in vehicle cabins that had been
parked for two hours without any shade. Immediately after they entered the
cabin, they ran one of the test conditions: (1) all windows in the cabin were
fully lowered and the air conditioning (AC) system was off (CON); (2) all
windows were closed and the AC was set at the first speed level (AC 1); or (3)
all windows were closed and the AC was set at the second speed level (AC 2).
The attempt to decrease the air temperature in the cabin by opening all the
windows did not provide a significant impact on the participants’ physiological
responses. Decreasing the air temperature by turning the vehicle air
conditioning on lowered mean skin temperature and heart rate, but not core body
temperature. However, using the first or second speed of the AC did not make
any significant difference in the physiological responses of the volunteers.

Keywords: Physiological responses; Vehicle air conditioning system; Vehicle cabin
