Misunderstanding 1: Turn on the air conditioner and smoke in the car
Some people turn on the air conditioner and light a cigarette when they stop to rest or wait in the car, which seems to be very refreshing. But doing this is harmful to your health. The reason is very simple. Because the doors and windows are closed, the smoke cannot be discharged all at once, which will naturally stimulate your eyes and respiratory system. But if you have a "smoking addiction" and you don't smoke at this time, you will be very uncomfortable. Well, let me give you a small suggestion, adjust the air conditioning ventilation control to the "exhaust" position, at this time, the smoke in the car can be discharged smoothly. out of the car.
Tip: Parking and turning on the air conditioner is already harmful. If you smoke again, it is really a mistake and a mistake. You should quit. If you can't resist smoking, remember to adjust the air conditioning ventilation control to the "exhaust" position.
Misunderstanding 2: Choose the temperature of the air conditioner at will
Some people turn the temperature very low in order to cool down, which seems to be very refreshing. However, in doing so, the endocrine system of the human body is easily unable to adjust, and it is easy to get sick, such as arthritis, frozen shoulder, colds and so on. When the indoor temperature is controlled too low, such as below 20°C, it will cause a variety of discomforts, such as lower extremity soreness, general weakness and chills, headache, sore throat, abdominal pain, backache, neuralgia in the limbs, and even severe cases of mouth pain. Symptoms such as crooked eyes. If there are elderly people or filial piety in the car, it is better to set the temperature at 27 ℃.
Tip: Under normal circumstances, the difference between the temperature inside the car and the outside temperature is 5°C to 6°C, so it is best for the owner to check the outdoor temperature when adjusting the temperature.
Misunderstanding 3: The air conditioner is always on in low gear
When the air conditioner is turned on in the car, most people will not drive to the maximum gear, thinking that doing so will cost fuel, and the noise of the fan is too loud, which is annoying. Of course, this kind of thinking is not wrong, but if you always do not drive to the maximum gear like this, you will also get sick. Don't worry, the thing is like this, when the air conditioner is in use, it will suck in a lot of dust and form dirt. After a long time, mildew will occur, and then it will be released into the car through the air conditioner, and it is easy to be inhaled in the car. not sick? Therefore, you should always turn on the air conditioner to the maximum block, and blow out the dirt in the air conditioner through strong wind.
Tip: Every once in a while, turn on the air conditioner to the maximum gear and blow it for half an hour to effectively prevent dust accumulation.
Misunderstanding 4: Turn on the air conditioner as soon as you enter the car
The weather outside is hot, and the inside of the car is even hotter. As soon as you get into the car, a heat wave hits and the heat is unbearable. Your first reaction may be to turn on the air conditioner and hope that the cool wind will dispel the heat wave - you are wrong again. This not only does not have a good cooling effect, but also increases the pressure of the engine during initial operation. So if the heat is hot, you still have to endure it first. After getting in the car, first open all the windows, start the external circulation system of the air conditioner, and exhaust all the hot air. After the temperature in the car drops, close the windows again. Turn on the air conditioner and adjust it to a suitable temperature.
Tip: The car is very hot, the first action to get in the car should be to open the window, start the external circulation of the air conditioner, and exhaust the hot air.
Misunderstanding 5: Open the inner loop and open it to the end
All car owners know that the air conditioner has a "circulation" button. Pressing this button will only circulate the air in the cabin internally. When the doors and windows are all closed, the cooling efficiency of the air conditioner will be fully "absorbed", which can save energy. This seems to be understandable, but there is a drawback. After a long time, the air in the cabin will become more and more turbid, and there will even be a feeling of hypoxia. How to do it? The internal circulation system can be turned on, but it cannot be used for a long time. When the air conditioner is just turned on, it is best to use the external circulation first. After the temperature is lowered, switch to the internal circulation, and then switch between the internal and external circulation at regular intervals. Especially when parking, it is best to switch to the "outer circulation" function.
Tip: Remember to switch the inner and outer circulation every once in a while, and leave it alone after turning on the air conditioner.
Misunderstanding 6: Air conditioning is also used when driving at low speeds
In order to keep cool, some people turn on the air conditioner when they get in the car, no matter they are driving at low speed or high speed, which is wrong again. If you still use the air conditioner when driving at low speed, the engine will run at a higher speed artificially when you encounter traffic jams while driving, which will reduce the service life of the engine and the air conditioner compressor. Therefore, it is best not to use the air conditioner when driving at low speeds.
Tip: When encountering a traffic jam, the car will naturally slow down, then remember to turn off the air conditioner.
Misunderstanding 7: Stacking items near the air intake
Some people are accustomed to making the carriage very messy. For example, various items are stacked near the air intake. The seemingly random behavior is actually very bad. Doing this can block the air intake and allow the air conditioning system to circulate air. hindered. Some people will complain that the air conditioner is not cool enough to see if the air intake is blocked.
Tip: Keep the cabin neat and tidy, and pay special attention to removing items near the air intake to ensure proper air circulation.
Misunderstanding 8: The wind direction of the air conditioner blows at will
Some people don't pay much attention to it. After turning on the air conditioner, let the air conditioner blow in the wind direction, or even choose the mode of blowing the windshield. This is not right, because the temperature of the windshield glass is high, which will cancel most of the cooling effect. Therefore, it is best to choose to blow upwards, which is in line with the law of cold air sinking down.
Tip: Don't be too troublesome, turn on the air conditioner and choose the wind direction to blow upwards, so that the cooling effect is good.
Misunderstanding 9: Turn off the air conditioner after turning off the flame
Turn on the air conditioner, hum a little tune, feel very comfortable along the way, reach the destination, turn off the fire, and then remember to turn off the air conditioner, which is the habit of many car owners. However, the consequence of this is that it will cause a large number of molds to multiply in the air conditioner due to humidity, and when you start the car the next day, it will ignite with the pressure of the air conditioner, so the high load brought by this will cause the engine cause damage.
The right thing to do is to drive on the road with the air conditioner on, and think about turning off the air conditioner a few minutes before you stop and turning on the natural wind later. Because, the temperature in the air-conditioning duct rises before stopping, which will eliminate the temperature difference with the outside world, which can keep the air-conditioning system relatively dry and prevent the reproduction of mold.
