After exposure to the sun, open the window to cool the heat quickly, usually the use of the air conditioner improper resulting in physical discomfort often occurs, in fact, the use of car air conditioning is a lot of skills, although it is only a few simple buttons, but the combination of different effects is very different. In a car exposed to outdoor sunlight, the temperature inside the car can reach 50 °C. Every time I just get into the car, the owner is tormented. Even if the air conditioner is turned on, it is a little difficult to cool the hot air at 50°C by the air conditioner alone. You can only feel a hint of coolness in the air vent, and the back of the hips against the chair is still extremely hot. In fact, before getting in the car, open all the windows or doors and let the heat out first, you will feel much better. Then open the glass, open the sunroof with a sunroof, open it for a while, dissipate the heat, and then close the window, you will feel that the air conditioning effect is much better.
When using air conditioning, internal and external circulation should be rotated, and air conditioners generally have internal and external circulation switches, and when using external circulation, air conditioning enters air from outside the car, and internal circulation is the circulation of air inside the car. Internal circulation can improve the effect of air conditioning, which is equivalent to recooling the indoor cold air, and the air conditioning effect is of course better. However, long-term use of the internal circulation will reduce the air quality in the car, which may make people feel dizzy. The internal circulation should be opened for a while, and the external circulation should be used to allow fresh air to enter 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, allowing the appropriate amount of air outside the car to enter, which can not only improve air quality, but also improve the effect of air conditioning. In addition, when using air conditioning to defrost and defog, it is only effective to use external circulation.
Turn off the air conditioner before turning off the fanMany people use the car in the 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 igniting, and the starter is loaded with a large load. In addition, the temperature in the air conditioning duct is low and humid, which may cause mold to multiply in the air conditioning duct, causing odor. It is recommended that the car owner turn off the air conditioner before parking and let the fan continue to run, so as to dry the pipes and reduce the chance of mold growth.
Car air conditioner use pay attention to the misunderstanding that the air conditioner always turns on small air volume: most car owners mistakenly think that the air conditioner will consume more fuel when it is turned on in large gear, so they will try to choose to open a small air volume. In fact, otherwise, during the use of the air conditioner, often absorb a certain amount of dust, thus forming dirt, after a long time, mildew will occur, if long-term to a small amount of wind mainly, it is difficult to blow out the dirt in the air conditioner, but will affect the health.
