Hello Ladies and Gentlemen!I'm Brother Jie Xiu, today let's talk about a major event in the air conditioning industry - fluoridation of air conditioning R32 refrigerant. Oops, doesn't that sound a little nervous?Don't worry, follow the steps of Brother Jiexiu, and I guarantee that you will come"Fluorine circles"Seconds change"Fluoride people"！
First of all, we have to understand where this r32 is sacred. R32, also known as difluoromethane, is a new generation of environmentally friendly air-conditioning refrigerant, and now it is popular, and major air-conditioning manufacturers have used it to replace the older generation of products. Since it is so important, the air conditioner lacks it and naturally has to be replenished in time, which is the key link of our "air conditioner R32 fluoride".
Q1: How can you tell if the air conditioner needs to be fluoridated?
Don't worry, Brother Jie Xiu tells you a few symptoms: "The air conditioner is not cool like a sauna, the temperature of the air outlet is like room temperature, and the compressor works manically but does not work well." In these cases, it is likely that your air conditioner is calling: "Master, I am hungry, I want to eat 'fluoride rice'!".”
Q2: What is the operation process of air conditioner R32 fluoridation?
Safety is indispensableThe first task is to wear protective glasses, gas masks and gloves, and wear protective clothing, this is to avoid direct contact with R32, after all, although people are refrigeration masters, they are not so friendly to the human body.
Equipment inspection and preparationConfirm that the air conditioner is turned off and the power is off, find the fluoride port at the low pressure end (generally marked with the word "S" or "low pressure"), connect the fluorine bottle and vacuum pump, make sure that there is no air leakage in the pipe, and start vacuuming after everything is in order.
Precise fluorideThe system pressure is observed through a pressure gauge, and in general, the pressure value of R32 is about 0 at an ambient temperature of 305-0.7MPa. Slowly open the valve of the fluorine bottle, observe the pressure gauge while adding fluoride, and stop adding fluoride immediately when the appropriate pressure is reached.
Run the testAfter the fluoride is added, turn on the air conditioner, enter the refrigeration mode, check whether the temperature of the air outlet drops significantly, and continuously monitor the stability of the system pressure to confirm that there is no leakage and the refrigeration is normal.
Q3: What are the precautions in the process of fluoridation?
A: Brother Jie Xiu reminds you that you must stabilize your mind during the whole process, don't panic, and remember the following points:
Confirm one step at a time", and check the tools and interfaces before each step
Slow work out fine work", the fluoride speed should be slow to prevent the pressure from being too high instantly
Safety first", do a good job of personal protection throughout the process to avoid accidents;
The amount of fluorine is moderately good", the right amount is good, too much or too little will affect the performance of the air conditioner.
To sum up, it is not complicated to add fluoridation to the air conditioner R32, as long as you follow the correct steps, coupled with the intimate tips of Brother Jiexiu, even non-professionals can easily get started. Of course, if you still feel that you don't know the bottom of your heart, then ask a professional maintenance master to help, after all, "professional things are handed over to professional people", which is also the principle that Brother Jiexiu has been advocating. The next time the air conditioner is not cool, think about Brother Jiexiu, remember to check whether it is a lack of fluoride first, maybe the problem can be solved!
See you next time, my friends, I hope your air conditioners are "full of fluorine" and cool in the summer!
