Learn how to clean automotive air-conditioning maintenance

The first air-conditioning portal is the air-conditioned grid. Does it need to be cleaned or replaced in the hot summer months? Experts suggest that although owners are advised to change the air-condition grid at the same time when they normally perform routine maintenance in the spring, if the airline of the car suddenly has a small or loud noise, or the air-conditioning cooling is not obvious, it is necessary to consider replacing the air-conditioner. Yes.

In spring, it is rainy and it is rainy in summer. Many dust, moisture, leaves, and other impurities with moisture will accumulate on the evaporator after passing through the air-conditioning grid. This causes the odor in the car, in addition to making the air-conditioning work unsmooth. To eliminate odors, one can spray special bactericides on the one hand. On the other hand, the owner should change the air-conditioner cells one time a year. Consider the case where the above-mentioned air volume is small or the air-conditioner emits a loud whining noise. Replace the air conditioning grid.

Experts advise: Try to do a “steam antivirus” at a regular auto-cosmetics store. This can lead to damage to the air-conditioning system because steam anti-virus will generate a lot of moisture. Failure to remove moisture in time can lead to damage to circuit equipment.

Cleaning evaporator

If the air conditioning grid does not change for a long period of time, there is a small wind or odor, then you need to clean the evaporator. Experts said that ordinary air-conditioning grids often use two kinds of liquid medicine during the cleaning process. One is a disinfectant for air-conditioner cells, and the other can remove dust accumulated on the evaporator by ultrasonic atomization or using a high-pressure method. And hair and other impurities, these impurities after ultrasonic atomization, will be discharged through the air conditioning outlet. After some cleaning, the air conditioner can work normally, and it can blow out the clean breeze.

Experts advise: Evaporators are inconvenient to maintain and do not need to be cleaned frequently. Therefore, to ensure the normal use of air conditioners, it is necessary to pay attention to the cleaning and replacement of the air-conditioning grids. Generally, one sterilization is performed once a year or the air-conditioning grid is replaced by the same way.

Replace snow and dry bottles

As the air-conditioning cooling snow (also known as "refrigerant"), when it will be replaced? Experts pointed out that most cars now use "environmentally friendly snow species." Normally, they are replaced within three to five years. Drying bottles that filter the moisture content of air-conditioning pipes are replaced every three years.

In addition, according to the international agreement, since the 1st of this month, China has completely shut down production and will no longer be allowed to use R12 (Friang) as the refrigerant. Most of the refrigerants currently used for refrigeration are environmentally-friendly alternatives, R134a. Pan Zifan reminds the owner that the price is R134a. Slightly higher, so some of the mixed snow types in the market that are mixed with R12 are sold to owners, and neither environmental protection nor deception to consumers.
