As the temperature rises, many car owners have begun to use car air conditioners. Some car owners feel that the car is not cool when using the air conditioner. At this time, their first reaction is: the car air conditioner is lacking fluorine and it is time to add fluoride. Coolpei.com consulted experts and reminded that car air conditioners are not cool. Do not blindly add fluoride. You must first determine whether there is a fluoride deficiency. Inexperienced car owners are advised to go to a professional car repair shop to add fluoride and try not to do it yourself.
Experts said that there are four most common reasons why car air conditioners are not cool:
1. The quality and purity of fluorine. The quality and purity of fluorine play a vital role in vehicle air conditioners. Generally, poor quality fluorine will lead to inefficient operation of the air conditioner.
2. Condenser and water tank. The heat dissipation of the condenser and water tank will also affect the use of the air conditioner. If they are not cleaned for a long time, the condenser and water tank will be covered with foreign matter and dust.
3. Use of fluorine. Many car owners think that the more fluorine in the air conditioner, the better, but this is not the case. During the fluoridation process, the amount of fluorine must be neither too much nor too little. If it is less, the pressure in the air conditioning pipe will be insufficient, and if it is too much, the pressure will be too high. In the above two cases, the air conditioner cannot operate normally for cooling.
4. The quality of the expansion valve. The expansion valve is an important component in the refrigeration system and is generally installed between the liquid storage cylinder and the evaporator. A poor-quality expansion valve will prevent the refrigerant from functioning as it should.
Experts remind that if the car air conditioner is not cool, the most important way to determine whether it is deficient in fluorine is to observe the glass observation hole on the air conditioning duct in the engine compartment:
1. When the air conditioner is normal When running continuously, there are no bubbles in the glass holes. When the air conditioner stops, bubbles will appear briefly, indicating that the amount of fluorine is normal.
2. When the air conditioner is running normally and continuously, there are continuous bubbles in the glass holes, indicating that the amount of fluorine is insufficient and needs to be added.
3. When the air conditioner is running normally and continuously, there are no bubbles in the glass holes. When the air conditioner stops, there are no short-term bubbles, indicating that the amount of fluorine is too much and needs to be discharged.
Experts said that if the car owner does not find the glass observation hole, there is a simple way to make a rough judgment: open the car hood and check whether there are oil stains on the air conditioning system connector. If so, it should be missing. Fluoride. Before adding fluoride to the car air conditioner, it is necessary to conduct an overall inspection of the vehicle's air conditioning system to ensure that there are no leaks in the air conditioning equipment before adding fluoride.
