1. After exposure to the sun, open the window first to dissipate heat and cool down quickly
Usually, improper use of air conditioners leads to physical discomfort. In fact, there are many skills in using car air conditioners. Although it is only a few simple buttons, the effects of different combinations are very different.
In a car exposed to the sun, the temperature inside the car can reach 50 degree . Every time you just get in the car, the owner is suffering. Even if the air conditioner is turned on, it can be a little difficult to cool the 50 degree hot air with the air conditioner alone. You can only feel a hint of coolness from the air outlet, and the back of the buttocks close to the seat is still unbearably hot.
In fact, before getting in the car, open all the windows or doors to let the heat out first, and you will feel much better. Then open the glass, open the sunroof with a sunroof, open it for a while to dissipate the heat, and then close the window, you will feel that the air conditioning effect is much better.
2. When using the air conditioner, the internal and external circulation should be used in turn
Air conditioners generally have internal and external circulation switches. When external circulation is used, the air conditioner enters the air from outside the car, while the internal circulation is used to circulate the air inside the car.
Internal circulation can improve the effect of air conditioning, which is equivalent to re-refrigerating indoor cold air, and the effect of air conditioning is of course better. However, using the internal circulation for a long time will reduce the air quality in the car, which may make people feel dizzy. You should use the external circulation for a few minutes after opening the internal circulation for a while to allow fresh air to enter the car and improve air quality. If the internal and external circulation switch of the air conditioner is a mechanical lever instead of a button, the lever can be placed in the middle of the internal and external circulation, so that the air outside the car can enter the right amount, which can not only improve the air quality, but also improve the air conditioning effect. In addition, when using the air conditioner to defrost and defog, it is only effective to use the external circulation.
3. Turn off the air conditioner and then turn off the fan before turning off the flame
Many people use the car in summer, but the AC switch of the air conditioner compressor has not been turned off, and the fan has been turned on for a long time. The consequence of this is that when your car is ignited, it starts with the compressor, and the starter load is heavy. In addition, the temperature in the air-conditioning duct is low and humid, which may lead to the proliferation of mold in the air-conditioning duct and cause odor. It is recommended that car owners turn off the air conditioner and let the fan continue to run before parking, so as to dry the pipes and reduce the chance of mold breeding.
