【Car owner’s home car knowledge】If you ask what is the most annoying thing about driving in summer, it must be the "heat wave hitting your face" before driving. A car after being exposed to the sun is like a "steamer", and sitting in it is like being in a "sauna". So, after being exposed to the sun in summer, is there any good way to quickly lower the temperature inside the car?
1. Turn on the air conditioner directly
Recommended instructions:★★★★
Faced with this problem, many people in real life do this: get in the car, close the windows and turn on the air conditioner, thinking that turning on the air conditioner in a confined space is the best way to lower the temperature. As everyone knows, not only will the temperature in the car not drop quickly enough, but it will also fill the car with the pungent smell that the air conditioner blows out when it is first turned on.
The correct approach is: first open the windows for ventilation, then turn on the air conditioner and open the external circulation when the vehicle is running stably. When the temperatures inside and outside the cabin are similar, close the windows and start the internal circulation. This is the most common approach!
2. Swing the car door
Recommended instructions:★★
There is also a quick cooling method that is widely circulated on the Internet: "swinging the car door." The method of operation is to first open the passenger window, and then repeatedly open and close the driver's door to release the hot air in the car.
Theoretically, this approach is fine. But what is the effect? To this end, we conducted an experiment and the result is: the method is feasible but the effect is not very obvious. It can probably reduce the temperature by about 6 degrees. In addition, it should be noted that this cooling method has almost no effect on the rear rows. .
Therefore, it is better to use the method of swinging the car door with caution. It is not worth sweating profusely just to reduce the temperature so much.
3. Spray cooling agent
Recommended instructions: ★★
This kind of spray will indeed feel cool immediately when it is sprayed on the corresponding area, but the effect will fade away after a while. And it should be noted that this kind of spray can only cool down the local temperature quickly, and it will not have much effect on cooling the entire car. Therefore, spraying cooling agent to reduce the temperature will not work.
4. Take a cold shower
Recommended instructions:Not recommended
Facing the scorching heat, people can take a shower to relieve themselves. When the car is facing the scorching heat, can it be cooled down? No, because in a high-temperature environment, if cold water is used for direct contact, the temperature difference will be huge, which will inevitably cause varying degrees of damage to the vehicle's internal structure and paint surface.
