After some time of use, car air conditioners may decrease their cooling effects, usually due to inadequate refrigerants (commonly known as fluorine). At this point, a "fluorinated" operation is required. The basic steps and precautions for fluorinated car air conditioning are summarized below and presented in tabular form。
I. Basic fluorinated automobile air conditioning processes
1. Check for fluorine leakage from air conditioning systems
Before adding fluorine, a leak in the system should be confirmed. If leaks occur, they will need to be repaired before fluorinated。
2. Preparation tools and materials
Safety equipment such as fluorinated equipment, pressure meters, refrigerant bottles, gloves, goggles, etc. Are required。
3. Connecting pressure sheets
The pressure sheet is connected to the high-low-pressure port of the air conditioning system to monitor the pressure of the system。
4. Start engines and turn on air conditioning
In engine operation, the air conditioner is activated and set to the maximum cooling mode to put the system into operation。
5. Determination of refrigerant adequacy
The need for fluorine is judged by the pressure values shown in the pressure table. The normal pressure range for different types of vehicles varies and reference to the vehicle manual is recommended。
6. Slow fluorine
Open refrigerant bottle valves, slowly inject refrigerants, while observing pressure table changes and avoiding overcharges。
7. Testing of refrigeration effects
When fluorine is completed, the air conditioner is shut down and waits for a few minutes to be activated again to test whether the cooling effect is restored。
8. Check for leaks
Once fluorinated, leak detectors or soap water can be used to check for leaks at connections。
Ii. Car air conditioning plus fluorine attention
Attention
Contents
Safety first
Operate with protective equipment to prevent refrigerant contact with skin or eyes。
Don't raise your bets at will
Suitable refrigerants must be selected according to vehicle type and refrigerant type。
Pressure control
Be careful with pressure table readings during fluorination to avoid over and under。
Avoid excess
Excess fluorine is not only a waste of resources but may also damage compressors。
Check for leaks
Fluorinated systems must be identified before they are leaked, otherwise they will not solve the problem。
Professional operations
If there is uncertainty about the method of operation, it is recommended that fluorine be applied by professional maintenance staff。
Iii. Question answers
Problem
Answer
Must it be fluorine
Not necessarily, but also fan failure, condenser stains, compressor damage, etc。
Can you add fluorine to yourself
Yes, but with the right methods and tools in mind, it is easy to make mistakes。
What are the types of refrigerants
R134a and r12 are common, with different types of vehicles。
What if the fluorinated air conditioning doesn't cool
It may be system jamming, compressor failure or excess fluorine that require further detection。
Summary
Fluorinated car air conditioning is a relatively simple maintenance exercise, but requires some expertise and operational skills. The correct fluorine increases not only the cooling effect of air conditioning, but also the useful life of air conditioning systems. The owner is advised to read the description of the vehicle carefully prior to the operation or to seek the help of a professional technician to ensure that the operation is safe and effective。
