Lose your life if you don't use it well! Car air conditioning is particular
After autumn, it is reasonable to say that starting from this day, the temperature should be cool and cool. There is also a proverb: "The day of the beginning of autumn is cool." However, some cities in China are still raging with heat waves. The car has become the best road tool to temporarily avoid the heat, but did you know? If the car air conditioner is used improperly, there is a danger of death! Today I will talk about how to use the air conditioner properly during the heat. I hope it will help you.
Turning off the air conditioner without turning off the air conditioner is the main cause of air conditioner odor. Because the temperature of the evaporating box is very low after the flame is turned off, the water vapor in the air will condense into small water droplets, which will moisturize a large number of bacteria in a humid environment. These molds can cause headaches, fever, sudden sore throat, tonsil infections, asthma, flu symptoms, dermatitis, and difficult wound healing. The correct approach is that the driver should turn off the cooling of the air conditioner 1 km or a few minutes before arriving at the destination and switch to the blowing mode. This will allow the temperature in the air conditioning duct and the evaporator to rise, eliminate the temperature difference with the outside world, and take away moisture. What if there is a musty smell? I have tried a method that is very effective. Open the door, adjust the air conditioner to the heater, and adjust the wind to the maximum. After a few minutes, the musty smell is basically gone. If you are interested, you can try it.
Some people like to let the air vent of the air conditioner blow at themselves. Although it is cool, it is not good for health. Blowing cold wind for a long time can easily bring various discomforts to the human body, and severe facial paralysis may be possible! Some people do not pay attention to the wind direction, let it blow at will, or even choose the mode of the windshield, this is also wrong, because the high temperature of the windshield glass will cancel most of the cooling effect. The correct way is to choose to blow obliquely upwards. According to the principle of physics, the law of rising and falling of hot air is used to allow cold air to cool the car from top to bottom.
When you turn on the air conditioner in the car, most people don't turn it on to the maximum gear, thinking that doing so will cost gas, and the fan's noise is too loud, which makes people annoying. Of course there is nothing wrong with this kind of thinking, but if you don't drive to the maximum gear like this, you might get sick. Don’t worry, it’s like this. When the air conditioner is in use, it will suck in a lot of dust. The water vapor and dust that gradually condense in the evaporator will form dirt. It’s easy to inhale it in the car. Isn’t this sick? The correct way is to turn on the air conditioner to the maximum block every once in a while, blowing for half an hour can effectively prevent dust accumulation.
Usually, when the air in the car is not good, we will open the outer loop. However, when the air conditioner is turned on, many car owners are concerned that using the external circulation will cause the cold air in the car to run out, which will cost fuel. However, if the internal circulation is used for a long time, the air in the cabin will become more and more turbid, and there will be a feeling of hypoxia such as dizziness. The correct approach is when the air conditioner is just turned on, it is best to use the outer loop first, and then switch to the inner loop after the temperature drops, and then switch the inner and outer loops at regular intervals. Don't turn on the air conditioner and leave it alone.
When waiting for people, many car owners have had the experience of sleeping in the car with the air conditioner and the windows closed. At this time, the carbon monoxide in the vehicle exhaust is likely to enter the car through the air inlet of the air conditioning system. In a closed space, the concentration of carbon monoxide is too high, which can lead to poisoning and even death. News reports are not uncommon. Is it safe to drive the window? Not really! If the air around the car is not circulating, such as in the garage, the harmful gas produced by the engine may also "poison" the sleeping car owner.
Many friends just turn the air-conditioning temperature button to the lowest in order to cool down. This is really cool, but it is not good for our health. When a person suddenly switches from a hot environment to a very cold environment, the body's endocrine system cannot be adjusted immediately, and this will cause diseases such as arthritis and colds. When the temperature is too low, it will also cause physical discomfort, such as body aches, chills, headaches, abdominal pain and other symptoms. In addition, if there are elderly or children in your car, don't let the car cool too much. Under normal circumstances, the temperature in the cabin should be 7°C different from the outside temperature. This temperature difference will also make people feel the most comfortable.
If you don’t park in the basement, the car will be heated by the sun outside and it will make the cabin hotter. I believe your first reaction at this time is to turn on the air conditioner and hope to quickly cool down. In fact, this cooling effect is not good, because the air in the car and the air-conditioning pipeline is also very hot under long-term sun exposure. If the air-conditioning is turned on at this time, the hot air from the air outlet will blow directly to you, making you Feel more uncomfortable. The correct way is to open the windows before getting on the car to let the air in the car discharge to the outside of the car through convection; at the same time, turn on the air conditioner to blow the hot air out of the air conditioning duct. It does not need to be too long for 20-30s. At this time, if you close the window and turn on the air conditioner, the effect will be better.
Summary: The air conditioning system is the most commonly used comfort configuration, but the more familiar things the more details that should be paid attention to. Therefore, we should pay more attention to it when using car air conditioning in the future. After all, it is closely related to our safety and health. .
