[汽车修理知识]8 operations make the car air conditioner uncomfortable

Some novices always think of cleaning the air conditioner only when the air conditioner is not effective. This is wrong.Beijing Sanyuanqiao ToyotacarZhang Liwei, deputy director of the technical department of the sales and service center, pointed out that the air conditionerFilterIt needs to be replaced regularly, because there is a lot of sand and dust in Beijing in spring, and catkins will fly. These will stick to the filter, which will easily grow bacteria and cause the air conditioner to produce a musty smell. Therefore, it is best to replace it once a year after spring. in addition,CondenserIt also needs to be cleaned regularly, andWater tankRemove it for thorough cleaning. Misunderstanding 2 Adjust the direction of the air outlet of the air conditioner at will Some car owners do not pay attention to adjusting the direction of the air conditioner when using the air conditioner, which is not conducive to the best effect of the air conditioner. Zhang Liwei pointed out that according to the principle of sinking cold air and rising hot air, the correct approach should be to set the air outlet upward when turning on the air conditioner and downward when turning on the heater. Misunderstanding 3 Do not turn on the air conditioner all winter In some areas, the winter is relatively warm, and some car owners do not use air conditioning throughout the winter.Master Zhang Lidong of Beijing Shouqi Toyota Motor Sales and Service Co., Ltd. pointed out that if the air conditioner is not used for a long time, its rubber ring will be aging.lubricating oilIt will also dry out. Regularly starting the air conditioner will allow all parts to receive lubrication and maintain good condition. Therefore, it is best to start the air conditioner once a week in winter. Misunderstanding 4 keep the air conditioner on for a long time Some car owners often turn on the air conditioner after getting in the car. Zhang Zhang pointed out that long-term use of air conditioner will makeCondenserExcessive pressure will cause loss to the refrigeration system. Therefore, you should not use the air conditioner for too long each time. If the temperature in the car has reached a comfortable temperature, you can turn off the air conditioner and turn it on again after a while. Misunderstanding 5 When entering the car in summer, immediately open the inner loop In the hot summer, many car owners are accustomed to turning on the internal circulation of the air conditioner as soon as they enter the car, thinking that this can make the temperature in the car drop faster. Li Jingxiang, chief engineer of Beijing COSCO Toyota Motor Sales & Service Co., Ltd., pointed out that because the temperature inside the car is higher than the temperature outside the car, this is not effective. When you first enter the car, you should first open the windows for ventilation and turn on the external circulation to exhaust all the hot air. After the temperature in the cabin drops, switch to internal circulation. Misunderstanding 6 Long-time open inner loop Li Jingxiang pointed out that because the internal circulation is the circulation of air in the enclosed space of the car, the oxygen content in the car will continue to drop, and if the gasoline in the cylinder is not completely burned, the unburned carbon monoxide of the engine may also leak into the car. Therefore, the air quality in the car will get worse and worse, and even cause harm to the human body. Therefore, the inner circulation should be opened for a while, and the outer circulation should be opened for a while to allow fresh air to enter the compartment. This is also the reason why you cannot sleep in the car with the inner loop. Misunderstanding 7 Turn off the flame and then turn off the air conditioner Some car owners often think of turning off the air conditioner after the engine is turned off. Li Jingxiang pointed out that this is harmful to the engine, because the engine will start with the load of the air conditioner when the vehicle is started next time. Such high load will damage the engine. Therefore, the air conditioner should be turned off and then turned off after each parking, and the air conditioner should be turned on after the vehicle is started for two or three minutes and the engine is lubricated. Misunderstanding 8 never use large air volume Some car owners do not like the noise made when the air conditioner is turned on to high gear, so they rarely or never turn on the air conditioner to high air volume. Li Jingxiang pointed out that the air conditioner sucks in a lot of dust when it is in use. Regular high wind can blow out the floating dust on the inner surface of the air duct of the air conditioner. This is a simple way to keep the air conditioner clean. In addition, a dedicated air duct cleaning fluid should also be used for sterilization, cleaning and deodorization. 　　 Add fluoride to a regular store Some car owners report that some small-displacement vehicles use air-conditioning when driving at low speeds. The speed will be fast and slow. Zhang Liwei said that there is no need to worry too much about this. Since the air-conditioning will increase the load on the engine, this is normal. At this time, the accelerator can be slightly depressed. It has to be heavier. Zhang Lidong reminds everyone that it is best to add fluoride at a regular 4S shop. If you go to a small repair shop to add fluoride, you should pay attention to whether the maintenance staff has filled it up. You can pay attention to the filling port. After the bubbles are generated, add 50-100 Ke fluorine is enough, and also pay attention to let the maintenance personnel check the leak. Li Jingxiang reminded car owners that the water temperature of some old cars will reach 95-105 degrees Celsius when the air conditioner is on, and the air conditioner is not cold. At this time, the engine will be worn out and even deflagration will occur. This may be due to poor water circulation and needs to be overhauled.
