1. Open windows for ventilation
There are tricks to opening windows for ventilation. Opening all the windows is not the best way to ventilate.
Open the windows diagonally. Don't rush to turn on the air conditioner. Open the front and rear diagonal windows first, then drive the car at a low speed for a while to discharge the hot air from the car. After 2-3 minutes, close the windows and turn on the cooling. In this way, the cooling efficiency of the air conditioner will be higher. high.
2. Use tools to cool down
As the demand for cooling continues, many products have been developed, which have a certain effect on cooling the car. *Car sunshades must have been used by many car enthusiasts. Most sunshades are made of materials such as aluminum foil, which have good heat absorption and can block part of the direct sunlight from the vehicle, thereby achieving the purpose of cooling the interior of the vehicle. Not only that, it can also prevent the interior from aging.
Some sunshades are placed on the front windshield from outside the car, and some are held inside the car like umbrellas. Either way, they can reflect sunlight and avoid direct sunlight. If your car is often parked in a parking space exposed to direct sunlight in summer, you can buy one and give it a try.
** The main component of car cooling spray is dry ice. When dry ice sublimates into carbon dioxide in the air, it needs to absorb a large amount of heat, thereby rapidly lowering the surrounding temperature.
When using car cooling spray, spray it on the seats, steering wheel and other parts to achieve an instant cooling effect. However, since the spray volume of the spray can itself is very small, and the heat absorption of dry ice is also extremely limited, it can only assist local cooling.
It should be noted that this kind of rapid cooling spray must not be sprayed directly on glass or leather goods at close range to avoid a sharp drop in temperature, causing water intrusion and explosion of the above items; it cannot be sprayed on the human body within a range of 30cm, otherwise it will be very serious. It can easily cause frostbite to the skin.
3. Car window method
No need to use any other tools, just 30 seconds, the temperature drops by 10℃! First, roll down the right side glass of the rear row, then quickly open the main driver's door and then close it, and repeat this action several times. This is based on the principle of air flow. When the driver's door is opened, the outside airflow will enter the car along the right rear window and be drawn out along the driver's side, which is equivalent to replacing the originally high-temperature air in the car.
It should be noted that it is best to open doors and windows diagonally, that is, the main driver's door and the right rear window, or the passenger door and the left rear window. Because in this way, the hot air in the car can be exhausted most efficiently.
4. Use air conditioning to cool down
When driving, first open all the windows to allow air to circulate inside and outside the car. At the same time, open the external circulation of the air conditioner, wait for 2-3 minutes to let the hot air escape, then close the windows and change the external circulation to internal circulation. This method has a better cooling effect, but it is more time-consuming and is not suitable when you are in a hurry to use the car.
** Blow the air outlet upwards
The feeling of cold wind blowing against your face is indeed very refreshing, but adjusting the direction of the air outlet at will will affect the cooling efficiency of the air conditioner. According to the principle of cold air sinking and hot air rising, adjusting the air outlet upward during cooling can achieve the best effect. Cooling effect.
5. Find a parking space
If conditions permit, parking the car in an underground garage or a shady place can make the car much cooler. In addition, when a vehicle is exposed to the sun, the temperature inside the vehicle can reach 50 degrees Celsius, so do not open the door and get into the vehicle immediately.
The interior of the car will also cool down quickly by opening and closing the doors. The operation method is to lower all the windows on one side and open and close the door on the opposite side at normal speed about 10 times to quickly cool down.
