Attention to the use of car air conditioners 1. The air conditioner always opens the minimum air volume
Misunderstanding: Most car owners mistakenly think that turning the air conditioner to the maximum speed will consume more fuel, so they will try to choose a small air volume. In fact, it is not. During the use of the air conditioner, a certain amount of dust is often sucked into the air conditioner to form dirt. After a long time, mildew will occur. If a small amount of wind is used for a long time, it is difficult to blow the dirt in the air conditioner. Out, but will affect the health of the body.
Risk of injury: ★★★
Tip: Every once in a while, the air conditioner needs to be turned on to the maximum gear, about 10 minutes to effectively prevent dust accumulation. Or clean the air conditioner filter by the way when washing the car. If possible, it is also helpful to use air conditioner cleaner appropriately.
Note on the use of car air conditioners 2. Open the air conditioner in the car to smoke
Misunderstanding: Friends who are addicted to smoking will mistakenly think that smoking in the car and turning on the air conditioner will reduce the smoke concentration. In fact, this is not the case. Even if it is "cold air", if the car is not ventilated, the smoke will still stimulate the respiratory system, which is equivalent to Been smoking secondhand smoke.
Secondhand smoke: Secondhand smoke is also known as sidestream smoke. Although mainstream smoke and sidestream smoke come from the same cigarette, their chemical composition and quantity are very different because of their very different formation conditions. The combustion temperature of mainstream smoke is as high as 900℃, which is rich in oxygen, multi-distillation, and acidic, while the combustion temperature of sidestream smoke is 600℃, which is oxygen-depleted, multi-reduced, and alkaline. Both mainstream smoke and sidestream smoke contain thousands of chemical components, including dozens of carcinogens, but compared with the two, sidestream smoke is more toxic. For example, after lighting a cigarette, the content of carbon monoxide, nicotine, and carcinogenic benzopyrene and nitrosamine in sidestream smoke are 5 times, 3 times, 4 times, and 50 times that of mainstream smoke, respectively.
Risk of injury: ★★★☆
Tip: It is harmful to turn on the air conditioner when parking. If you want to smoke in the car again, remember to adjust the ventilation control of the air conditioner to the "exhaust" position.
Attention to the use of car air conditioners 3. Choose the temperature of the air conditioner at will
Misunderstanding: According to the outdoor temperature, car owners will generally choose different air conditioning temperatures to "be cool". However, when the indoor temperature is low for a long time, the body will not be able to adapt quickly due to the endocrine system, which will cause a variety of discomforts, such as lower extremity pain, general weakness and chills, headache, sore throat, abdominal pain, backache, neuralgia in the limbs, In severe cases, symptoms such as crooked eyes may even occur.
Risk of injury: ★★☆
Tip: Under normal circumstances, the temperature in the car should be adjusted to about 26~27 degrees.
Attention to the use of car air conditioners Fourth, the wind direction of the air conditioner blows at will
Myth: Can the wind direction and location also affect the temperature inside the car? This is indeed the case, if the wind direction of the air conditioner is adjusted at will, it will not only be worth the loss, but will not have a cooling effect.
Risk of injury: none
Tip: If the air outlet mode of the air conditioner is not selected properly, the cold air blown by the air conditioner will cool down the high temperature components that do not need to be cooled, thereby offsetting the cooling effect. Therefore, it is best to choose the tuyere to blow upward, which can conform to the law of cold air sinking. In addition, the wind direction block is best to choose the blowing surface block, so that the cooling effect is the most uniform.
Attention to the use of car air conditioners 5. The air conditioner is turned on and the internal circulation is turned on to the end
Misunderstanding: The internal circulation of the air conditioner will save energy due to all the "absorption" of the cooling efficiency. This seems understandable, but after a long time, the air in the cabin will become turbid or even hypoxic.
Risk of injury: ★★★☆
Tip: When the air conditioner is just turned on, you can use the external circulation to reduce the temperature in the car first, and then switch to the internal circulation, but remember to switch between the two modes every once in a while.
Attention to the use of car air conditioner 6. Parking and turning on the air conditioner to rest
Misunderstanding: Don’t think that it’s okay to stop and turn on the air conditioner to rest. In fact, this is a very dangerous thing, because when the car engine is working, if the gasoline in the cylinder is not completely burned, it will produce high concentrations of carbon monoxide, which will cause poisoning and even death. When the car is driving, the carbon monoxide concentration in the air-conditioned car is very low due to the convection caused by the air passing through the air-conditioning equipment.
Injury risk: ★★★★★
Tip: It is necessary to check whether the engine cover and chassis are leaking from time to time. When there is exhaust gas leakage in the car, it should be repaired in time.
