Now that summer has arrived, the weather in many places is getting hotter and hotter, and people are usually fine at home, but when they go out to face the hot sun, people who do not exercise often are really a bit overwhelmed. Nowadays, people basically use transportation as soon as they go out, and cars are the most used of them.
Many people have had such an experience when using a car in the summer: when they just open the door when they get on the car in the summer, a hot air comes to the face, and the feeling of getting on the car at this time is exactly the same as that of the sauna, and the hot air not only makes people feel heavy, but also makes people extra irritable.
According to the owner's description, the car is exposed to the sun for an hour, the temperature in the car may directly reach a high temperature of about 70 degrees, and the high temperature in the car will not disperse, which will not only make people feel uncomfortable, but also let some toxic gases endanger the health of the elderly and children. So what do we have to do to quickly reduce the temperature in the car when using the car in the summer? Don't worry, I'll teach you a few methods today.
Open the car external circulation, the car external circulation is the physical circulation system of the car air conditioner, in the summer with the car to open the external circulation after the car air will be replaced with the outside air, which is conducive to the rapid recovery of the temperature inside the car to the same extent as the outside world.
After opening the car external circulation is not enough, then we can also open all the car windows, including all the side windows and sunroofs of the car, according to the physical principle, the cold air sinks and the hot air floats, so opening all the windows of the car, especially the sunroof, is more conducive to the replacement of hot air in the car. Of course, if it is a new car, it is recommended to open all the doors to form convection, and if necessary, you can also fan the co-pilot door back and forth to empty the harmful gases in the car quickly, which can also make the temperature in the car drop faster.
After opening the car's outer circulation and all the windows, after a few minutes, the temperature inside the car can basically recover to a similar degree to the outside world, and then turn on the car air conditioner, not only better cooling effect, but also more fuel-efficient. When driving the car air conditioner, there is a small trick, that is, try to open the air conditioner outlet upwards, so that the cold air is blown out from above, and then it drops rapidly due to gravity, and the hot air discharge effect is better.
In the case of an emergency, we can't wait for such a slow operation, at which time we can prepare a bottle of homemade cooling agent in advance. The production of the cooling agent is very easy, the use of a small amount of alcohol to add a lot of water mixed together, usually when on the car to take out in the car to spray around on the line, so that the use of alcohol heat absorption principle, the car spray a little bit can quickly cool down, of course, alcohol must be diluted enough, otherwise the summer in the car spraying high concentrations of alcohol is simply in death.
After the car cools down, everyone turns on the air conditioning in the car. When turning on the air conditioner in the summer, many people are accustomed to opening the internal circulation and closing all the windows, so that the cooling effect is faster and better. However, it is actually unsafe to do so when driving for a long time, the car is in a closed state for a long time, and the air in the car cannot be replaced in time, which will cause the driver's mental fatigue and drowsiness. The correct approach is to open the external circulation every once in a while to replace the air, if you always forget, you can leave a little gap in the sunroof of the car, so that there will be no noise when driving, and it will be safer. What do you think about that?
