1. After exposure to the sun, open the window first to dissipate heat and cool down quickly
Usually, improper use of air conditioners causes physical discomfort. In fact, there are many techniques to use car air conditioners. Although it is just a few simple buttons, the effect of different combinations is quite different.
The temperature inside a car under outdoor exposure can reach 50°C. Every time I just get in the car, the owner is suffering. Even if the air conditioner is turned on, it is a bit difficult to rely on the air conditioner to cool the hot air at 50°C. You can only feel the coolness of the air outlet, and the back of the hip close to the seat is still very hot.
In fact, open all the windows or doors before getting in the car to let out the heat first, and you will feel much better. Then leave the glass open, open the sunroof with the 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 the external circulation is adopted, the air conditioner takes in air from outside the car, while the internal circulation uses the air inside the car to circulate.
Internal circulation can improve the air-conditioning effect, which is equivalent to re-cooling the cold indoor air, and the air-conditioning effect 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 open the internal circulation for a while and use the external circulation for a few minutes to let fresh air into the car and improve the 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 to allow the air outside the car to enter in an appropriate amount, which can not only improve the air quality, but also improve the air conditioning effect. In addition, when the air conditioner is used for defrosting and defogging, it is effective to use the external circulation.
3. Turn off the air conditioner and then the fan before turning off the flame
Many people use the car in summer, the AC switch of the air-conditioning compressor has not been turned off, and the fan has been turned on for a long time. The consequence of this is that your car starts with the compressor when it is ignited, and the starter load is heavy. In addition, the temperature in the air-conditioning duct is low and humid, which may cause a large number of molds to multiply in the air-conditioning duct and cause peculiar smell. It is recommended that car owners turn off the air conditioner before stopping the car and let the fan continue to run, so as to dry the pipes and reduce the chance of mold reproduction.
