As temperatures rise, 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, the first reaction is: the car air conditioner lacks fluoride, and the fluoride is added. After the auto market alliance experts reminded that the car air conditioning is not cool, do not blindly add fluoride, we must first determine whether the lack of fluoride. Inexperienced car owners, it is best to add fluoride to a professional car repair shop, try not to operate on their own.
According to experts, there are four kinds of reasons why air conditioners are not cool:
First, the quality and purity of fluorine. The quality and purity of fluorine play a crucial role in air conditioning in cars. In general, poor quality fluorine can cause air conditioning to operate inefficiently.
Second, the condenser and the water tank. The heat dissipation of the condenser and the water tank will also affect the use of the air conditioner. Failure to clean it for a long time will cause the condenser and the water tank to be covered by foreign matter dust.
Third, the use of fluorine. Many owners think that the more fluorine in air conditioners, the better. This is not the case. In the process of adding fluorine, the amount of fluorine is neither too much nor too little. Less pressure will make the pressure in the air-conditioning tube not enough, but the pressure is too much. In both of the above cases, the air conditioner is unable to operate normally.
Fourth, the quality of the expansion valve. The expansion valve is an important part of the refrigeration system and is generally installed between the cartridge and the evaporator. Poor expansion valves can make the refrigerant less than expected.
Experts reminded that car air conditioning is not cool, to determine whether the lack of fluoride, the most important method is to observe the glass observation hole in the air conditioning pipe in the engine compartment:
First, when the air conditioner is running normally, there is no air bubble in the glass hole. When the air conditioning is stopped, there will be brief air bubbles, indicating that the amount of fluorine is normal.
Second, when the air conditioner is running normally, there are bubbles in the glass hole, indicating that the amount of fluorine is insufficient and needs to be added.
Third, when the air conditioner is in normal operation, there are no bubbles in the glass holes. When the air conditioning is stopped, there are no short-lived air bubbles, indicating that the amount of fluorine is large and needs to be discharged.
Experts said that if the owner did not find the glass observation hole, there is a simple way to roughly determine: open the car cover, check the air conditioning system connector is not traces of oil, if any, it should be the lack of fluoride. Before the automobile air conditioner adds fluorine, it is necessary to do an overall inspection on the air conditioning system of the vehicle to ensure that the air conditioning equipment does not leak before it can be added with fluorine.
