1, open the window for ventilation
Opening windows for ventilation is skillful, and opening all the windows is not the best way for ventilation.
Open the inclined windows, don't turn on the air conditioner in a hurry, first open the front and rear inclined windows, then drive at a low speed for a while, first exhaust the hot air in the car, and then close the windows for refrigeration after 2-3 minutes, so that the air conditioning refrigeration efficiency is higher.
Step 2 use tools to cool down
With the increasing demand for cooling, many products are produced, which have a certain effect on the cooling of automobiles.
* Car sunshade, which must have been used by many riders. Most awnings are made of aluminum foil and other materials, which have good heat absorption and can block some direct sunlight from the vehicle to achieve the purpose of cooling the vehicle. Not only that, but also the aging of the interior can be avoided.
Some parasols cover the front windshield from the outside of the car, and some are supported in the car like umbrellas. Either kind can reflect sunlight and avoid direct sunlight. If your car is often parked in a direct sunlight parking space in summer, you can buy one and try it.
* Vehicle cooling spray, the main component of which is dry ice. When dry ice sublimates into carbon dioxide in the air, it needs to absorb a lot of heat, thus rapidly reducing the surrounding temperature.
When the vehicle cooling spray is used, it can be sprayed on the seat, steering wheel and other parts to instantly cool down. However, because the spray amount of the spray tank itself is very small, the absorption of heat by dry ice is extremely limited, and it can only partially assist in cooling.
It should be noted that this kind of rapid cooling spray must not be sprayed directly on glass and leather goods at close range, so as to avoid the sudden drop of temperature causing the above items to burst into water; Do not spray it on the human body within 30cm, otherwise it will easily freeze the skin.
3. Window method
Without any other tools, it only takes 30 seconds, and the temperature drops suddenly 10℃!
First roll down the right rear glass, then quickly open the main driver's door and then close it, and cycle this action many times. This is based on the principle of air flow. When the main driver's door is opened, the outside air will enter the car from the right rear window and be pumped out with the main driver's side, which is equivalent to replacing the original high-temperature air in the car.
It should be noted that it is best to choose diagonal corners when opening doors and windows, that is, the main driver's door and the right rear window, or the co-pilot door and the left rear window. Because of this, the hot air in the car can be discharged most efficiently.
Step 4 cool down with air conditioner
* air conditioning internal and external circulation method
When driving, first open all the windows to let the air inside and outside the car circulate, and at the same time open the external circulation of the air conditioner, wait for 2-3 minutes for the hot air to come out, then close the windows and change the external circulation into internal circulation. This method has a good cooling effect, but it takes a lot of time and is not suitable when you are in a hurry to use the car.
* The air outlet blows upward.
The feeling of cold air blowing on your face is really cool, but the random adjustment of the direction of the air outlet will affect the refrigeration efficiency of the air conditioner. According to the principle that cold air sinks and hot air rises, adjusting the air outlet upwards can achieve the best refrigeration effect in the refrigeration state.
