INFLUENCE OF WINDSHIELD TINT ON THE TEMPERATURE IN AUTOMOBILE PASSENGER COMPARTMENTS

The effect of tinting the glass of windshields on the air temperature in automobile passenger compartments was investigated. Measurements were performed with two nearly identical vehicles, one equipped with tinted windshield glass and one equipped with clear windshield glass. All other glass in both vehicles was tinted. Tests were performed statically, with the cars parked facing south, and dynamically, with the cars driven at approximately 80 km/h. In the static tests, the interior air temperatures as determined by liquid-in-glass thermometers were typically 2 to 3C cooler in the vehicle with the tinted windshield. In the dynamic tests, the differences in the interior air temperatures were smaller, typically about 0.5 to 1.5C. The interior air temperature differences determined with thermocouples varied with the thermocouple position.
