Relevant introductions and differences of various refrigerants

For the reliance on common appliances such as air conditioners and refrigerators, the input of refrigerants is also particularly critical, including the diversified applications of refrigeration equipment, and refrigerants have become an indispensable part. Let's take you to learn about various refrigerants!

1. R22 refrigerant is widely used in our country. Some professionals believe that if R123 can finally be lifted, then the day when R22 is lifted will not be far away. They are also doing their best to classify R22 as an environmentally friendly refrigerant, thinking that it will be considered in terms of environmental protection, safety, power, etc. , R22 is the most excellent refrigerant, and the damage of the ozone layer and the greenhouse effect are not only the influence of the refrigerant. R22 should not be used because of choking. Some experts in my country pointed out that my country’s ability to use R22 to 2040 was obtained through political and social value. If R22 is now banned according to the requirements of some manufacturers, the impact on the economy will be too great. Refrigerants and lubricating oils Both need to import, because our country is irresponsible to itself; besides, the fate of R123 and R22 is not yet determined.

2, R123, like R22, is also an HCFC refrigerant. Now some manufacturers are promoting R123 as a substitute for R22.

3. R134a refrigerant was originally presented as a substitute for R12. Its thermophysical properties and unit volume cooling capacity are close to R12. Now it has been widely used in heat pump units and household refrigerators. In the centrifugal chiller, R134a is also mainly used as the refrigerant.

4. R407C is a mixed refrigerant composed of 23% R32, 25% R125 and 52% R134a by mass percentage.

5. R410A is a mixed refrigerant composed of 50% R32 and 50% R125 by mass percentage.

6, R404A refrigerant is a mixed refrigerant composed of 44% R125, 52% R143a, and 4% R134a by mass percentage.

7, R134a, R407C, R404A, r410a, and R507 need to use synthetic oil, such as POE oil.

8, CFCs (chlorofluorocarbon): fully halogenated, without hydrogen in the molecule.

9, HCFCs (hydrochlorofluorocarbon): Partially halogenated, the molecule can contain hydrogen, chlorine, and fluorine together.

10, FC (perfluorocarbon fluorocarbon): The molecule contains only carbon atoms and fluorine atoms.

11, HFC (hydrofluorocarbon hydrofluorocarbon): no chlorine freon, part of the halogenated hydrogen in the molecule, does not damage the ozone layer, ODPu003d0.

At present, the supply of some products is sufficient. If you need to stock up before the year, you can stock up in advance to prevent price increases. Order hotline:!
