How to distinguish inferior refrigerants when purchasing refrigerants?

Currently, the application of refrigerants is quite extensive. The procurement of refrigerants has evolved from general offline channels to online channels. Buyers will also purchase through the Internet. However, there are many problems with the authenticity of refrigerants. , Especially for branded refrigerants, there are many inferior products, which are also so-called fakes. I will teach you some small methods. You can distinguish whether they are inferior refrigerants by the following methods:

1. Whether to purchase refrigerants produced by regular manufacturers through formal channels, such as refrigerants whose prices are significantly lower than the market prices, should arouse a high degree of vigilance, and do not buy fake products in the hope of a little cheaper at a low price.

2. If you have the test conditions, it is recommended to check the purity and acidity of the refrigerant before using it. It is not recommended to use the refrigerant whose test results are significantly lower than the industry standard.

3. If you do not have the refrigerant detection conditions, it is recommended to perform a simple inspection before using the refrigerant. The simple inspection method can be:

(1) Refrigerant The tank is turned upside down, and a small amount of refrigerant is released onto a piece of white paper. If there are obvious impurities or liquid water on the white paper, it means that the quality of the refrigerant is not good and it is not recommended;

(2) The pressure gauge is used to test the pressure of the refrigerant bottle. Compare the temperature and pressure characteristics table of the refrigerant to check whether the pressure in the bottle is within the normal range. If the pressure is obviously abnormal, it is not recommended.

Simple tips, the editor also tells everyone that the purity of the refrigerant will also affect the efficiency of its operation in the refrigeration system. Refrigerant products with purity up to the standard can provide resistance to the safe operation of the refrigeration system, while those with a purity that are not up to the standard will only cause the refrigeration system to be injured. According to the manufacturer's understanding, according to the international standard, the purity of air-conditioning refrigerant is above 98%, and the national standard of my country is above 96%. Taking DuPont or Lixue refrigerant R22 as an example, the purity of its superior grade is as high as 99.9%, so purchasers can use it with confidence to prevent being deceived.
