How to add refrigerant to refrigerator, knowledge of refrigerator refrigerant filling

Refrigerators are the same as air conditioners. It is inevitable that they will leak after a period of use. Many friends who don’t understand refrigerant often ask whether the refrigerant is toxic and whether it will harm human health during the filling process. Do you know how to add refrigerant to the refrigerator? The editor introduces you how to add refrigerator refrigerant.

Adding refrigerator refrigerant

1. When adding refrigerator refrigerant, ensure that the system has been shut down, and then connect the system.

2. When the system is connected, the high and low pressure valves should be closed, and the high and low pressure test connections of the system should be locked at the same time, and the vacuum pump connection should be tightened at the same time with the filling interface.

3. When vacuuming the system, first open the high and low pressure valve. At this time, the system starts to evacuate. After a period of time, check whether the system is completely vacuumed, then close the high and low pressure valve, and finally close Vacuum pump.

4. Disconnect the connection between the yellow tube and the vacuum pump when adding refrigerant, and then connect it to the refrigerant bottle and tighten it.

5. At this time, first open the refrigerant bottle, then open the valve core on the meter group to exhaust the air in the yellow tube, and then turn the refrigerant bottle upside down and put it away at the same time.

6. Open the high and low pressure valve, add refrigerant to the system, and close the high and low pressure valve after the specified amount is reached, and put the refrigerant bottle in place at the same time.

Is the refrigerator refrigerant toxic?

The main component of the earliest refrigerator refrigerant is ammonia. This kind of other has certain toxicity, long After time inhalation, it will cause poisoning, but later this kind of refrigerant is replaced by Freon. Freon refrigerant will not cause harm to the human body when it is used, but it will damage the ozone layer, in order to better protect the environment. To enhance the refrigeration effect of refrigerators, Freon refrigerants are gradually being replaced by new refrigerator refrigerants. The new type of refrigerant used in the refrigerator is non-toxic and will not cause any harm to the human body. The only thing that needs to be paid attention to is that you need to be very careful when adding the refrigerant. If it is not properly added, it will easily cause combustion and explosion.

So if you have relevant testing equipment and installation tools, you can fill the refrigerant yourself, and there will be no major problems in operation. However, if you have not been in contact with related industries, it is recommended to find a professional after-sales repair center to add, so as not to cause too little, too much, or leakage of refrigerant. The summary of refrigerator filling knowledge is for reference only!
