Cleaning methods and skills of automobile air conditioner?

When using automobile air conditioner, many problems will occur due to improper maintenance and use because air conditioner is a seasonal item. So how to clean the car air conditioner? The following is the cleaning method of automobile air conditioner that I arranged for you, hoping to help you.

Cleaning method of automobile air conditioner

1* * Clean the air inlet of the lower blower.

You can remove the wiper arm of the car, you can also remove the plastic plate under the windshield, and then use a professional sterilization cleaner to clean the air conditioner to treat the dust, or use an endoscope to observe it, so that it can be thoroughly cleaned!

2*** Clean the blower.

You can use a smaller tool to remove the blower, and you can use a brush to clean the blower impeller!

3*** Clean the evaporation box

It used to be very troublesome to clean the evaporation box, so the central control can be removed. There are many new cleaning methods now. Just open a cover plate under the co-pilot center console, you can also clean the water gun under the evaporation box, and you can also realize visual cleaning!

4*** Replace the filter element of the lower automobile air conditioner.

The filter element of automobile air conditioner is also used to prevent dust, so it should be cleaned regularly, especially when the air quality is not very good. Air conditioning filter should be replaced regularly according to the maintenance manual, and can also be tested when the seasons alternate!

5*** Clean the air conditioning pipes.

If the air-conditioning filter element still smells after replacement, you can also clean the air-conditioning duct, park your car in a place where the air environment is improved, turn on the external circulation switch, turn on the air-conditioning to the natural ventilation gear, and then aim the cleaning agent at the air supply outlet and spray it into the duct evenly. Open the window in a few minutes, turn on the air conditioner and ventilate thoroughly!

How to correctly maintain automobile air conditioning

First, choose the appropriate air conditioning temperature. Of course, in summer, many people like to keep the temperature very low. As we all know, when the temperature is too low, it will affect your health, so the temperature adjustment of air conditioner must be appropriate. The most suitable temperature for human body is 20℃ to 25℃. If it exceeds 28℃, people will feel sultry. And below 14℃, people will feel cold. Therefore, the air conditioner should control the indoor temperature between 18℃ and 25℃. Too low a temperature can easily make people sick.

Second, start the internal circulation immediately when you enter the car in summer. When the car is parked in the hot sun for a long time, some car owners like to turn on the air conditioner and turn on the internal circulation as soon as they start the car, thinking that this can make the temperature in the compartment drop faster. But because the temperature inside the car is higher than that outside the car, the effect is not good. When you enter the car for the first time, you should first open the window for ventilation and open the external circulation to exhaust all the hot air. After the temperature in the carriage drops, it is replaced by internal circulation.

Third, people all know to use air conditioners in a fully enclosed state. The same is true for car air conditioners. If the doors and windows are not tightly closed during use, the refrigeration effect will be poor and fuel will be wasted.

Fourth, the direction of the air outlet can be adjusted at will. Some car owners do not pay attention to the direction of air conditioning blowing when using air conditioning, which is not conducive to the best effect of air conditioning. According to the principle that cold air sinks and hot air rises, the correct way should be to turn on the cold air with the air outlet facing upwards and turn on the heating with the air outlet facing downwards.

5. Turn on the air conditioner for a long time. Some car owners always turn on the air conditioner after getting on the bus, but using the air conditioner for a long time will make the condenser pressure too high, which will cause losses to the refrigeration system, because the air conditioner is a heavy burden on the engine, and the engine itself is a heater, not to mention in high temperature weather. In this case, some small-displacement cars even have water boiling, which affects driving and reduces the efficiency of air conditioning. Therefore, it should not be too long to use the air conditioner every time. If the temperature inside the car has reached a comfortable temperature, you can turn off the air conditioner and turn it on later.

6. Don't smoke in the air-conditioned car. Because of smoking in the carriage, the smoke can't be discharged at once, which is harmful to the eyes and respiratory system. If smoking occurs, the air conditioning and ventilation control should be adjusted to the "exhaust" position, so that the smoke in the compartment can be exhausted outside the car.

7. Don't rest or sleep for a long time in a parked car, and turn on the air conditioner. Because the car is well sealed, when the car stops, there is poor ventilation in the car. If you turn on the air conditioner to rest or sleep at this time, it is likely that the CO gas discharged from the engine will leak into the car, leading to poisoning or even death.

Eight, try not to use air conditioning when driving at low speed. When encountering traffic jams, don't run the engine at a high speed to improve the efficiency of the air conditioner, because doing so will adversely affect the service life of the engine and air conditioner compressor.

9. Turn off the fire before turning 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 starts next time, the engine will start with the load of the air conditioner, and such a high load will damage the engine. Therefore, the air conditioner should be turned off after each stop, and then turned on after the vehicle starts for two or three minutes and lubricates the engine.

The secret of car maintenance

1 air battery

The air chamber is generally located in the engine compartment, and its function is to filter the air, make the air entering the combustion more pure, and then ensure the full combustion of fuel. However, the air intake grille will be deformed when used for a long time, which will affect the air filtration effect; Secondly, too much dust accumulated in the air chamber will reduce the air flow, so it needs to be replaced regularly. It is generally recommended that the replacement time of the air cabin be 40,000 kilometers. If the vehicle environment is poor, it can be replaced at 20 thousand kilometers.

2. Air conditioning grid

The function of air-conditioning grille is to filter the air-conditioning system to prevent impurities such as dust from entering the blower and affecting its life, and at the same time send clean air to passengers in the car. The air conditioner will be full of various impurities after being used for a long time, which will affect the air intake of the air conditioner. In addition, these impurities are also the source of odor. Generally speaking, the recommended replacement time of air conditioning grille is 20 thousand kilometers. The air conditioning cabin of most models is located in the glove box of the co-pilot, which is relatively easy to replace. Car owners with strong DIY ability can try it.

3. Oil boom

Oil will produce a lot of impurities in the process of continuous circulation. The function of oil grid is to filter these impurities, improve the purity of oil, and thus reduce engine wear. The replacement time of the oil grille depends on the oil, so the replacement period varies from 5000- 10000 km depending on the oil.

4. Gasoline grille

There are some impurities in pure gasoline, and the function of gasoline grille is to filter out these impurities to ensure the purity of gasoline entering the combustion chamber. If the gasoline grille is not replaced for a long time, the engine is prone to problems such as carbon deposition, dead fire and power decline. Generally speaking, the recommended replacement time of gasoline grille is 20,000 kilometers.
