How Much Temperature Difference Between Black and White Cars in Summer?
1 Answers
In summer, black cars are 5-15 degrees Celsius hotter than white cars. Factors affecting the interior temperature include the car's color and material, interior color, and outdoor temperature. Car color and material: Under direct sunlight, the temperature difference between different colored panels can exceed 20 degrees Celsius. White cars reflect sunlight, with a metal temperature difference of up to 25 degrees Celsius compared to black car panels. White car paint has a lower temperature, while black car paint has a higher temperature. This means darker-colored cars absorb more heat, while lighter-colored cars absorb less. Therefore, when black and white cars are parked for the same duration, the white car's temperature will be lower than the black car's. Interior color: Under the same conditions, white interiors are about 7 degrees Celsius cooler than black interiors. Theoretically, color spectrum theory indicates that lighter colors absorb less heat, while darker colors absorb more. The impact of white car interiors on cabin temperature is smaller compared to black car interiors. Outdoor temperature: In summer, outdoor temperatures in most regions can reach around 40 degrees Celsius. When a car is exposed to the sun for a long time in such high temperatures, the interior temperature can exceed 70 degrees Celsius, with a maximum of up to 90 degrees Celsius.
