The first door of the air conditioner is the air conditioner compartment. Does the car air conditioner compartment need to be cleaned or replaced in the hot summer? Experts suggest that although it is recommended that car owners generally replace the air conditioner during regular maintenance in the spring, if the wind of the car suddenly becomes less or noisy, or the air conditioner is not obvious, consider replacing the air conditioner. Grid. There are more rainy seasons in spring and heavy rains in summer. A lot of dust, lint, leaves and other impurities with moisture will accumulate on the evaporator when passing through the air-conditioning grid. In addition to making the air-conditioning work poorly, this is also the cause of the peculiar smell in the car. To eliminate the odor, you can spray a special antiseptic solution on the one hand. On the other hand, the car owner should change the air conditioner compartment once a year. When the above-mentioned air volume is small or the air conditioner is turned on and the loud noise is "whooping", it should be considered. The air conditioner compartment has been changed.

Experts remind: try not to do "steam antivirus" in some roadside car beauty shops, this will cause damage to the air conditioning system, because steam antivirus will produce a lot of moisture, and the moisture that is not discharged in time will cause damage to the circuit equipment.

Price: Domestically produced products are generally around RMB 100, while those with activated carbon are generally around RMB 150.

●Clean the evaporator

If the air conditioner compartment is not replaced for a long time and there is a small wind or a peculiar smell, then the evaporator needs to be cleaned. Experts said that in ordinary air-conditioning compartments, two kinds of syrup are often used during the cleaning process. One is a fungicide for the air-conditioning compartment, and the other can be used to remove the dust accumulated on the evaporator through ultrasonic atomization or high-pressure methods. Impurities such as hair and hair, these impurities will be discharged through the air conditioning drain after being atomized by ultrasound. After some cleaning, the air conditioner can work normally, and the clean cool breeze can be blown out again.
Experts remind: The evaporator is inconvenient to maintain and does not need to be cleaned frequently. Therefore, to ensure the normal use of the air conditioner, you need to pay attention to the cleaning and replacement of the air conditioner. Generally, it is sterilized once a year or at the same time as the air conditioner is changed.
Price: If the two methods are used at the same time, about 400 yuan.
●Replace refrigerant and dry bottle
As the refrigerant used for air-conditioning (also known as "refrigerant"), when will it be replaced? Experts point out that most cars now use "environmental-friendly refrigerants", which are usually replaced every 3 to 5 years, and the drying bottle used to filter impurities and moisture in the air conditioning pipeline is replaced every 3 years.
In addition, according to Pan Zifan, a technical expert from Guangzhou Caiang Auto Cooling Technology Co., Ltd., according to international agreements, starting from the 1st of this month, China will stop production and no longer allow the use of R12 (Frion) as a refrigerant. Most of the refrigerants currently used for refrigeration are As an environmentally friendly alternative to R134a, Pan Zifan reminds car owners that because R134a is slightly more expensive, some mixed refrigerants mixed with R12 are sold to car owners, which is not environmentally friendly and deceives consumers.
Experts remind: these twoAccessoriesGenerally need to be professionalcar repairIt is recommended that the owner do not “DIY” privately or go to the street shop to make it. In addition, the refrigerant is practical, and there is no need to pursue a more expensive brand. The quality effect between foreign and domestic refrigerants does not actually have a price.
