For those who own a black car, they are very concerned about whether their car will be hotter than other colored cars or not if they have to expose themselves to the summer sun? Indeed they were rightly worried about this.
Have you ever wondered why the boxcars, when exposed to the harsh summer sun, become a true “sauna” . Turns out, they have a pretty similar relationship with the way you still choose light-colored clothes to avoid the sun.
We have known for a long time that dark colors absorb more heat from sunlight while light colored clothes reflect better. That concept turns out to apply to cars as well.
Vehicles painted in silver and other paint colors other than black can increase the vehicle’s anti-heat effect.
During the period 2008-2009, the state of California, USA considered a ban on the sale of black cars, not out of concern for the comfort of its residents, but out of concern about the unfavorable environmental effects of cars. Black absorbs heat from sunlight.
According to a 2011 study conducted by the Berkeley Lab Environmental Energy Technology Laboratory, cars painted in silver and other paint colors other than black can increase the effectiveness of the vehicle’s heat resistance. The study tested on two silver and black Honda Civic cars. They found that lighter silver cars reflect about 60 percent more sunlight than darker cars.
Efficiency from the ability to reflect sunlight helps reduce 2% of fuel used to turn on the air conditioner in the car, reduce 1.9% of CO 2 emissions to the environment and 1% of other harmful emissions. from a car with black paint.
Or in a 2015 test of the Autotrader site, they tested two black and white cars exposed to the hot summer outdoors in Georgia, USA. The results showed that the temperature inside the black car was extremely hot up to 54 degrees Celsius, while the white car was only 45 degrees Celsius.
Then another test to check the cooling capacity of the air conditioning system in two black and white cars. Not surprisingly, the cooling system pulled the temperature inside the white car down to about 28 degrees Celsius after just 10 minutes. At the same time, the black car’s air conditioner only managed to cool down to 32 degrees Celsius.
Another experiment by YouTube channel BuzzFeedBlue also placed two black and white cars in the sun. The results showed that the surface temperature of the black car increased to 76 degrees Celsius, while the white car was only 58 degrees Celsius.
Test for two black and white cars exposed to the sun at the same time.
The black car has a temperature of up to 76 degrees Celsius.
And the white car is only at 58 degrees Celsius.
Legislators argue that a hotter car will require more energy to cool and keep the interior of the car cold. This wastes fuel, increases the harmful emissions emitted by a vehicle,
Therefore, reducing the number of black cars on the road can contribute to reducing the amount of smoke and greenhouse gases emitted into the environment, against global warming. Although the state of California has not passed the law in the end, perhaps every citizen must be aware of this to reduce the greenhouse effect.
A vehicle exposed to direct sunlight will heat up quickly, reach high temperatures, and retain heat longer than a vehicle parked in the shade.
So it can be temporarily concluded, the notion that cars with black or dark colors are easier to heat in the summer are completely correct. Therefore, if possible, you should use sunshades that are able to reflect sunlight for your vehicle.
