【Owner's home car knowledge】Summer is the season when car air conditioners are used most frequently, and it is also the season when people in cars rely on air conditioners the most. Whether the air conditioner can be used well determines whether the car owner can spend this summer comfortably. Proper use of the air conditioner can not only lower the cabin temperature in a shorter time, but also reduce the engine load and increase the life of the compressor.
As we all know, in summer, as long as the vehicle is placed in the sun for a few hours, the temperature inside the car will reach 60-70 degrees Celsius. In this case, if you sit in the car, it is really no different from entering a sauna.
1. Open the window before turning on the air conditioner
Therefore, we can usually find that the first action of many car owners when getting in the car is to turn on the air conditioner. In fact, this will bring hidden dangers to people's health. Because CCTV's "Is it Real?" column has done experiments, and it is confirmed that after the car is exposed to the sun, the interior will emit benzene, formaldehyde and other carcinogenic gases. At this time, if you turn on the air conditioner as soon as you enter the car, you may inhale these toxic gases.

Because CCTV's "Is it Real?" column has done experiments, and it is confirmed that after the car is exposed to the sun, the interior will emit benzene, formaldehyde and other carcinogenic gases. At this time, if you turn on the air conditioner as soon as you enter the car, you may inhale these toxic gases.
The correct approach is not to enter the car immediately after being exposed to the sun, or not to turn on the air conditioner in a hurry after entering the car, but to lower all the windows or open the door, then turn on the fan to speed up the air circulation, and then turn off the car after a few minutes Windows open air conditioner. In this way, not only can the toxic substances be released, but also the cooling effect is better.
Of course, if your car is equipped with a remote start function, there is no need to be so cumbersome, and you can also avoid the pain of the heat wave, just start your car remotely 5 minutes before driving. By the time you actually get in the car, it will be already cool inside the car. However, it is still necessary to open the windows for ventilation before getting in the car.
2. Wind direction of the air conditioner: blowing obliquely upward
There is also the problem of the wind direction of the air conditioner. Some people don’t pay much attention to this. After turning on the air conditioner, let the wind blow freely, or even choose the mode of blower. In fact, it is not appropriate to do this because the temperature of the windshield is high. Will cancel most of the cooling effect. The correct way is to choose to blow upwards, so that the law of hot air rising and cold air falling is used to let the cold air cool down the interior of the car from top to bottom.
3. Do not keep low temperature for a long time
In addition, car owners should also pay attention not to blindly seek coolness while driving, and adjust the temperature of the air conditioner in the car to a very low level. Otherwise, people are prone to endocrine disorders due to the large temperature difference between inside and outside the car, which makes them more likely to get sick. In addition, turning the temperature of the air conditioner very low will also increase the fuel consumption of the car and increase the cost of the car. In fact, under normal circumstances, the difference between the temperature inside the car and the outside temperature is about 6°C.
4. Switching between internal and external cycles
If the car owner is driving for a long time, he must make full use of the internal and external circulation function of the air conditioner. Some new car owners may not understand it very well. In fact, the function of internal and external circulation is to control the air quality in the car and assist in heat preservation. Therefore, the car owner knows how to choose according to the bad environment of the vehicle. For example, the car is in a busy downtown area with traffic jams. In order to prevent the exhaust gas from entering the car, the car owner can use the internal circulation function of the air conditioner to ensure that the air in the car is not polluted.
At other times, we recommend using the outer circulation function as much as possible, because when the inner circulation is turned on, the interior of the car is equivalent to a closed state, and the air quality will decline after a long time, while the outer circulation is a real-time replacement with the outside air to ensure the freshness of the air degree.
5. Turn off the air conditioner before turning off the flame
The last point is that many people are used to getting out of the car without turning off the air conditioner, and turning off the engine directly. As everyone knows, although it is easy to do so, it will cause great damage to the air conditioner compressor, and bacteria will easily grow in the air conditioner duct over time. The correct way is to turn off the vehicle's air conditioning compressor, that is, the AC button, about 5 minutes before the vehicle arrives at the destination, let the blower continue to work, and dry the moisture in the air duct, and turn off the blower after reaching the destination , and turn off the flame. In this way, the working pressure of the air conditioner compressor can be effectively reduced, the service life can be prolonged, and problems such as mold and the like caused by accumulation of water vapor in the air duct can be avoided.
