Summer car air conditioning maintenance method
Summer has arrived, and the hot weather has undoubtedly made people more annoyed. The timely appearance of car air conditioners allows all car owners to drive away the hot air. However, improper use of car air conditioners can cause the following problems: in the cool world, sometimes inexplicably tired, dry skin, varying degrees of numbness in the hands and feet, headache, sore throat, neuralgia and gastrointestinal discomfort, these symptoms are typical "Air conditioning disease." Staying in the low temperature environment of car air conditioner for a long time, the cold feeling is transmitted to the brain's thermoregulatory center, instructing skin vasoconstriction, and the sweat glands distributed throughout the body to reduce secretion, thereby reducing heat dissipation and maintaining body temperature. The cold feeling causes the sympathetic nerve to be excited, causing the vasoconstriction of the abdominal organs, and the gastrointestinal motility is weakened, and the corresponding symptoms appear. In addition, most of the cars are closed and not ventilated, the air is turbid, and the air-conditioner itself emits some harmful gases. It is naturally prone to illness when it is in such an environment for a long time. So, how to properly use and maintain car air conditioners? Let Xiaobian take you to explore.
The correct way to use:
First, choose the right air conditioning temperature. Of course, in the summer, many people like to adjust the temperature very low. As everyone knows, when the temperature is adjusted too low, it will affect the health of the body, so the air conditioning temperature adjustment must be appropriate. The most suitable temperature for the human body is 20 ° C to 25 ° C. When it exceeds 28 ° C, people will feel stuffy. Below 14 ° C, people will feel cold. Therefore, the air conditioner should control the temperature inside the car between 18 ° C and 25 ° C. If the temperature is too low, it will easily cause illness.
Second, the summer enters the car and immediately starts the inner cycle. When the car is parked in the hot sun for a long time, some car owners like to start the car and immediately turn on the inner loop when starting the car. It is thought that this can make the temperature in the car drop faster. However, because the temperature inside the car is higher than the temperature outside the car, this is not good. When you first enter the car, you should first open the window to ventilate, and open the outer circulation to discharge the hot air. After the temperature in the cabin drops, switch to the inner loop.
Third, people know that they should use air conditioners in a fully enclosed state. The same is true for automotive air conditioners. If the doors are closed during use, the window will be closed tightly, which will result in poor cooling and waste of fuel.
Fourth, the direction of the air conditioning outlet is free to adjust. Some car owners do not pay attention to adjusting the direction of air conditioning when using air conditioners, which is not conducive to the best effect of air conditioning. According to the principle of sinking cold air and rising hot air, the correct way should be to open the air outlet when the air is opened and the air outlet when the air is turned on.
Fifth, open air conditioning for a long time. Some car owners often keep air conditioning after getting on the bus, but using the air conditioner for a long time will cause the condenser pressure to be too large, which will cause loss to the refrigeration system, because the air conditioner is a heavy burden on the engine, and the engine itself is a fever. Body, not to mention the hot weather. In some cases, some small-displacement vehicles may have water boiling, which affects driving and reduces air-conditioning efficiency. Therefore, the air conditioning time should not be used for too long. If the temperature inside the car has reached a comfortable temperature, you can turn off the air conditioner and turn it on again after a while.
6. Do not smoke in the car with an air conditioner. Because the smoke inside the compartment, the smoke can not be discharged at once, irritating the eyes and respiratory system, which is not conducive to health. If smoking, the air conditioning ventilation control should be adjusted to the "discharge" position, so that the smoke inside the compartment is discharged outside the vehicle.
7. Do not rest or sleep for a long time in an air-conditioned vehicle. Because the car is well sealed, when the vehicle is stopped, the air permeability in the car is poor. If the air conditioner is resting or sleeping at this time, it is likely that the CO gas emitted from the engine leaks into the car and causes poisoning or even death.
8. Try not to use air conditioner when driving at low speed. When traffic jams occur in traffic, do not operate the engine at higher speeds to improve air conditioning performance, as this will adversely affect the service life of the engine and air conditioner compressors.
Nine, first turn off the flame and then turn off the air conditioner. Some car owners often think of turning off the air conditioner after the flameout, which is harmful to the engine, because when the vehicle is next started, the engine will start with the load of the air conditioner, and such high load will damage the engine. Therefore, the air conditioner should be turned off and then turned off after each stop, and the air conditioner should be turned on after the vehicle is started for two or three minutes and the engine is lubricated.
Car air conditioners must not only be used correctly, but also have reasonable maintenance. The following small series will introduce four methods for car air conditioning maintenance:
Method 1: Fully check the air conditioner.
When using the air conditioner for the first time in summer, check the air conditioning system first. For example, check whether the refrigerant liquid and the air conditioner filter element are dirty through the liquid storage tank, and whether the radiator has foreign matter.
Method 2: Pay attention to the cleaning of the air conditioner.
Some newcomers always have to wait until the air conditioning effect is not good, only to think of cleaning the air conditioner, this is not right. The air conditioner filter that should be done should be replaced regularly, because there are many sand dust in Beijing spring, and the catkins fly, these will stick to the filter, it is easy to grow bacteria, and the air conditioner has a musty smell, so it is best to go after the spring every year. Replace it once. In addition, the condenser should be cleaned regularly, and the water tank should be removed and the cleaning can be thorough.
Method 3: After parking, do not turn off the air conditioner.
After the owner arrives at the destination, he usually leaves the air-conditioned door and leaves. Unlike the autumn and winter seasons, the huge temperature difference inside and outside the car in the hot summer season can cause mildew in the air conditioning system, which in turn breeds mold. Therefore, the owner should turn off the cold air a few minutes before reaching the destination, turn on the natural wind, and raise the temperature inside the air conditioning duct to eliminate the temperature difference with the outside world, thus keeping the air conditioning system relatively dry and avoiding mold reproduction.
Method 4: Regularly open large amounts of wind.
Some car owners rarely or never turn the air conditioner to a large amount of air because they do not like the noise generated when the air conditioner is turned to the high gear. However, when the air conditioner is used, it will absorb a lot of dust. Regularly opening a strong wind can blow out the floating dust on the inner surface of the air-conditioning duct. This is an easy way to keep the air conditioner clean. In addition, special air duct cleaning fluid is also used for sterilization, cleaning and odor removal.
