What is refrigerant? Inside the refrigerant you don’t know

When it comes to the invention of refrigerants, we naturally think of 'air conditioning.' Refrigerants bring people a more comfortable life, but the environmental problems they produce are also severe. Ozone layer destruction, global warming caused by the greenhouse effect, under the influence of the concept of sustainable development, research on new environmentally friendly refrigerants has become an urgent problem in the refrigeration industry. In this class, we will give a special explanation on the problem of refrigerants, let's get to know the refrigerants that you don't know!

1. What is a refrigerant?

The refrigerant, commonly known as 'refrigerantThe refrigerant R22 is a member of the Freon family and belongs to chlorinated halogenated hydrocarbons (the simple understanding is that the molecular structure 'CHF2Cl' contains the element 'chlorine (Cl)ingredient). Because this refrigerant is very harmful to the ozone layer, according to the Montreal Treaty, production has been frozen since 2016, and China has promised to stop using it completely in 2020. The Montreal Treaty, also known as the Montreal Protocol, is a treaty signed in Montreal, Canada by the governments of many countries under the initiative of the United Nations Environment Programme in 1987 to jointly stop the depletion of the ozone layer.

2. Those freon-backed pans in those years

When buying air conditioners, many businesses always promoted 'CFC-free' as a selling point of environmental protection. Is this really the case? Halogenated hydrocarbons, also known as Freon, are the general term for the halogen derivatives of saturated hydrocarbons (hydrocarbons) (Freon, a brand name used by DuPont in the United States for a long time). It appeared with the development of the chemical industry in the 1930s. A type of refrigerant. Because its invention has solved many years of difficult problems in the refrigeration industry, it has also become an important milestone in the development of the refrigeration industry.

In fact, there are many types of Freon. Due to the presence of chlorine (Cl) in some refrigerants, these refrigerants will generate a large amount of greenhouse gases during the slow oxidation and decomposition process, such as CO? etc. to destroy the ozone layer. . Although we have already said that it is the 'chlorine (Cl)' element in the refrigerant that destroys the ozone layer, but in order to facilitate consumer understanding, many businesses will also use 'chlorine (Cl)' in the refrigerant when replacing the work in China. 'Fluorine-free' is promoted as the selling point of the product.

3. The most widely used refrigerant

After the refrigerant R22 slowly withdrew from the stage of history, R410A has become the most widely used refrigerant. Its main components are R32 and R125, all of which do not contain 'chlorine (Cl)' elements. Because this refrigerant does not destroy the ozone layer, it is safe, safe and effective, and is being promoted by most air conditioner manufacturers. For example, Mitsubishi Heavy Industries’ K-standard central air-conditioning system adopts r410a refrigerant air-conditioning system. Compared with R22 system, it can greatly improve the cooling capacity and is safer and more environmentally friendly.

4. The most environmentally friendly refrigerant

Speaking of the most environmentally friendly refrigerant, in 1967, Sadhuslo proposed the use of ' Carbon dioxide CO? 'as a refrigerant. It is non-toxic and safe to use, that is, the pressure is extremely high within the temperature range of use. Due to the limited manufacturing capacity at that time, the equipment was extremely heavy and was once abandoned by civilian equipment. (Sadesiuszlo: It’s not time for me!) Fortunately, in recent years, due to its non-destructive effect on the atmospheric ozone layer and its good heat transfer performance, the theory of Sadhuszlo has again aroused extensive research. , 'Carbon dioxide CO?' has also been used as a refrigerant in certain occasions.

The importance of refrigerant as the 'blood' of air conditioner operation is self-evident. I believe that through today's introduction, it can help everyone to have some new understanding of refrigerants, so that more users can enjoy the high-quality refrigerant products and services provided.
