1、 After exposure to the sun, opening the window first cools down quickly
Improper use of air conditioning often leads to physical discomfort. In fact, there are many techniques for using car air conditioning. Although it is only a few simple buttons, the combination method has different effects.
The temperature inside a car can reach 50 ℃ when exposed to outdoor sunlight. Every time I just get on the car, the car owner is always suffering. Even if the air conditioner is turned on, relying solely on it to cool the hot air at 50 ℃ can be a bit difficult. You can only feel a hint of coolness from the air outlet, and the back of the buttocks next to the chair is still unbearably hot.
Actually, opening all the windows or doors before getting on the car and letting out the hot air will make you feel much better. Then open the sunroof with the glass open and a sunroof, open it for a period of time to dissipate the heat, and then close the window. You will feel that the air conditioning effect is much better.
2、 When using air conditioning, the internal and external circulation should take turns
Air conditioners generally have internal and external circulation switches. When using external circulation, the air conditioner receives air from outside the car, while internal circulation is used for internal air circulation.
Internal circulation can improve the air conditioning effect, which is equivalent to re cooling the indoor cold air. Of course, the air conditioning effect is better. However, prolonged use of internal circulation can reduce the air quality inside the car, which may make people feel dizzy and dizzy. You should start the internal circulation for a while and then use the external circulation for a few minutes to allow fresh air to enter the car and improve air quality. If the air conditioning internal and external circulation switch is a mechanical paddle instead of a button, the paddle can be placed in the middle of the internal and external circulation to allow an appropriate amount of air outside the vehicle to enter, which can not only improve air quality but also improve the air conditioning effect. In addition, when using air conditioning for defrosting and defogging, external circulation is necessary to be effective.
3、 Turn off the air conditioning before turning off the fan
Many people use their cars in the summer without turning off the AC switch of the air conditioning compressor, and the fan is also turned on for a long time. The consequence of this is that your car starts with a compressor when ignited, resulting in a high load on the starter. In addition, the low temperature and humidity inside the air conditioning pipeline may cause a large number of mold to multiply in the air conditioning pipeline, causing odor. It is recommended that car owners turn off the air conditioning and let the fan continue to operate before parking, in order to dry the pipes and reduce the chances of mold growth.
