There are two ways to add fluoride to automobile air conditioners, high-pressure end filling and low-pressure end filling. The high-pressure end is filled with liquid, which is safe and fast, and is suitable for the first filling of refrigeration system. The low-pressure end is filled with gas, which is slow and generally used for replenishment. Moreover, the quantity of each car is different, generally about 3 bottles are needed, and the price of adding a bottle to the store is around 200 yuan. Because fluoridation requires special tools and machines, it is recommended to go to a professional repair shop or 4s shop for operation.

Matters needing attention in the use of automobile air conditioner

Some car owners do not pay attention to adjusting the blowing direction of air conditioner when using air conditioner, which is not conducive to achieving the best effect of air conditioner. Zhang Liwei pointed out that according to the principle that cold air sinks and hot air rises, the correct way should be to turn on the air outlet upwards and turn on the air outlet downwards when heating.

Some car owners rarely or never turn on the air conditioner to high air volume because they don't like the noise when the air conditioner is turned on to high gear. Air conditioners will inhale a lot of dust when they are used. It is a simple way to keep the air conditioner clean by blowing strong winds regularly to clean the floating dust on the inner surface of the air duct. In addition, special air duct cleaning solution should be used for sterilization, cleaning and deodorization.
