Saying that a car that has been sunning for a day under the hot sun is open to the car, is there any wood like punishment? Now there is a good way to quickly cool down! Not open the door breathable! It is not right to start air conditioning cooling! Not to drive through the window at high speed! When summer comes, after the car is in the sun, enter the car, and really don't start air conditioning immediately! ! Using this method will allow the car to instantly drop 8 degrees!
One-way convection
Method: Only open the driver's window, repeatedly switch the cab door 5 times. Just slide the sub-driving glass and then switch the left front door 5 times at a constant speed to cool about 10 degrees. If you switch a few more times, you can also lower it.
Recommendation Index: ★★★★★
Is it amazing?
The method comes from a Japanese professor of aerodynamics. The principle is to use the door to fan the outside cold air into the car and replace the hot air in the car to achieve the purpose of cooling.
Do not open the air conditioner, do not drive through the window, the final is to Xiaobian pro-test effective Oh! And one person can do it, without the help of others, simply and quickly. However, the car temperature must be higher than the outside of the car, and the greater the temperature difference between inside and outside, the more obvious the cooling effect.
2. Multi-directional convection
Method: Simultaneously open the 4 doors to the maximum extent, switch the cab door uniformly, and repeatedly operate the driver door 5 times.
Recommended index: ★★★☆
Method 2 is an upgraded version of Method 1, so the principle is the same. Through scientific calculations, the doors of the cab were opened and closed with three doors closed, and only about 20% of the hot air in the car could be driven within 8 seconds, while the remaining three doors were opened and the cab door was opened. Cold air leaped into the car and 80% of the hot air in the car could be replaced within 8 seconds.
The cooling effect of this method is indeed better than the first one. However, there are certain limitations in domestic use. First, it is necessary to ensure that all four doors have enough space to open. Second, it is necessary to strictly observe the surrounding security when using it. It is better not to perform this method alone.
3, air conditioning + window
Method: Turn on the air conditioner, adjust to the maximum speed (4th speed), and open the outer loop. Open all windows and skylights at the same time. Close all the windows and skylights in about 1 minute, change the outer circulation to inner circulation, and reduce the air volume of the air conditioner to half.
Recommended index: ★☆
This is an earthy method that is frequently circulated online. Open the windows, skylights and open the outer circulation of the air conditioner to maintain ventilation inside the car, and replace the cold and hot air inside and outside the car to reduce the temperature inside the car. Then close the window to open the internal circulation, it is through the air conditioning and cooling to achieve further cooling purposes.
In addition to the need to turn on the air conditioning, there is a common problem that the moment the air conditioner is turned on, it will expel some hot air. These hot air may contain air that is not conducive to health. It may be better to start air conditioning directly or turn on the air conditioner directly or directly. Air conditioning is good, this method is not much different from taking off pants.
4, spray cooling method
Method: Close all the windows, open only the driver's side door, and spray a 45-yuan cooling agent into the 4 seats of the car for 10 seconds.
Recommended index: ☆
The main component of a cooling spray for vehicles is dry ice. Dry ice easily sublimates into carbon dioxide in the air. It needs to absorb a lot of heat and can quickly reduce the ambient temperature.
The cooling time is very short and the cooling rate is very small. The effect is not obvious. It is noteworthy that many sprays are mixed with aromatics, causing discomfort in closed vehicles and also affecting health, especially with respiratory diseases such as asthma, chronic bronchitis, emphysema, or allergies. The physique crowd should pay special attention.
In addition, the spray is placed in an environment with a temperature above 50°C for a long period of time (the vehicle in the vehicle after summer exposure is easily above this temperature), and it is also prone to cause an explosion hazard. It is not very cost-effective to use.
5, skylight negative pressure
Method: Close the doors and windows, open only the skylight, and drive at a low speed of 20km/h.
Recommendation index: ★
The method is based on the Internet. The principle is: the sunroof of a car uses negative pressure to ventilate and rely on the rapid flow of air on the roof to form the negative pressure inside the car when the car is driving. The air inside the car is extracted and the fresh air is added.
The cooling effect is not good, that is, one reason to open the skylight, it is better to open the air conditioning.
Long-term exposure to vehicles can cause windshield wipers and paints to change in quality, accelerating the aging of the seat's leather and console. So, try to park your car in the indoor parking lot or outdoor shade, avoid direct sunlight.
