As we all know, the engine is the heart of the car, and the air conditioning system is the lung of the car. With car air conditioning, we can enjoy a comfortable indoor environment. However, if such a delicate part is not taken care of, a strike is called a strike. I chatted with a friend the other day and learned that his car smelled bad as soon as it entered, and it smelled moldy. I didn't know there was something wrong with the air conditioner until I couldn't send it to the 4S shop for inspection.
It turns out that he has bought a car for more than a year now, and the air conditioner has not been maintained once. It's only a matter of time before the air conditioner goes wrong. Today, the author will take this opportunity to talk with you about how to post "autumn weight" on the car air conditioner in autumn and how to maintain it.
Comprehensive physical examination, prescribe the right medicine
As the saying goes, "Never fight an unprepared battle". Before formal maintenance, you can prepare for a comprehensive inspection of the air conditioner. For example, check whether the refrigerant is sufficient, how clean the condenser is, and whether the air conditioning switch and control elements are working normally, so as to know fairly well.
In addition, when the weather turns cold in autumn, riders should also check whether the defrosting air outlet works normally and whether the heat in the air outlet is sufficient, so as to avoid the adverse impact on driving safety in the later period due to inadequate inspection.
Clean and replace the air conditioning filter in time.
The high-quality air quality in the car mainly depends on the air conditioning filter. Just like the "mask" of a car, it is the filtering device of the air inlet of the air conditioner in the car, which filters out foreign impurities, so it is easy to be polluted, so it should be cleaned in time and replaced regularly. Otherwise, dust, bacteria, etc. What is attached to it will be blown into the car with air conditioning.
Under normal circumstances, when riders pick up their cars, manufacturers will remind them of maintenance, which involves the maintenance of air-conditioning filter elements. Don't be careless The air-conditioning filter element needs to be cleaned every 5,000 km or 3 months, and replaced every 20,000 km or 12 months. Of course, if riders use cars in a polluted environment for a long time, the replacement time of air conditioning filter elements should be advanced accordingly.
Clean the air conditioning pipes.
For the maintenance of automobile air conditioning, the cleaning of air conditioning pipeline is also very important. After the air conditioner is used frequently in hot summer, dirt, dust and bacteria will breed and deposit in the air conditioning pipeline. If the cleaning is not timely enough, the cooling effect of the air conditioner will be worse, the air output will also be affected, and the air conditioning system may malfunction.
Air conditioning pipeline cleaning can be carried out with special air conditioning cleaning agent. Before cleaning, it is necessary to shake the air conditioner cleaning agent evenly, adjust the air volume of the air conditioner to the maximum, adjust the temperature to the minimum, and adjust it to the external circulation mode. It should be noted that it is necessary to ensure that the air conditioner compressor does not turn on? (The air conditioning button is turned off). Then aim the shaken cleaning agent at the filter element, spray it into the internal pipeline to clean the air conditioning pipeline, and the cleaned dirt will be discharged from the air conditioning water outlet.
Maintain evaporation box and condenser.
As I said before, the air conditioner in the car is working at full load all summer, and there is more rain. After the car runs, impurities such as sediment, dust or flying floc can easily stick to the air conditioner condenser and evaporation box. If it is not cleaned in time, it will rust after a long time, which will lead to insufficient air conditioning and refrigeration, and it will also breed bacteria and cause odor inside the car. It is estimated that the problem of air conditioning in my friend's car is largely due to this reason.
Before cleaning the condenser with a water gun, brush off the impurities on the surface with a toothbrush or brush, and be careful not to damage the heat sink. Because of the structure and location problems, it is troublesome to disassemble the evaporation box, and improper disassembly and cleaning will lead to deformation of internal parts. I suggest that riders go to 4S shops or auto repair shops and be cleaned by professionals.
Conclusion: The car air conditioner will be maintained in autumn and its service life will be prolonged, and the interior environment will be much better. In addition to air conditioning, riders should also take time to conduct a comprehensive inspection and maintenance of the engine, tires, chassis, paint, wiper, etc. For vehicles, give them a "big health care", paste "autumn weight" and keep them online at all times.
