It's time to talk about refrigerants, do you know these things about refrigerants

Although it is winter, it is the time to talk about antifreeze, but the majority of friends in the auto repair circle know that now is also the time to prepare refrigerant products. Refrigerant sales are coming soon, let me talk about those things about refrigerants for everyone. Long, long ago, there was no refrigerant in the world, because people needed it, so they invented it. Around the beginning of the 19th century, refrigerant appeared and was first used in vapor compression refrigeration equipment designed and developed by Perkins.

The pace of exploration has not stopped for a moment. People have been looking for elements that can meet the characteristics of 'stable, non-toxic, non-flammable, and low boiling point' at the same time. They have gone through a century of exploration. , Finally locked the eight elements of 'carbon, nitrogen, oxygen, sulfur, hydrogen, fluorine, chlorine and bromine'. What is interesting, however, is that the refrigerant used before 1928 is composed of seven of the above elements, without the 'fluorine' element.

Until 1930, Majore and his assistants selected chlorofluorocarbon 12 (CFC12, R12, CF2CI2) and commercialized it in 1931, followed by a series of CFCs And HCFCs were successively developed, and finally mass-produced by DuPont in the United States, becoming the main refrigerant in the 20th century. The good times did not last long. People realized that although these refrigerants have brought convenience to people, they are also constantly harming the environment. Protecting the environment means protecting human beings. After the Montreal Protocol was passed in 1987, people began to actively seek new environmentally friendly products. alternatives. From 1990 to the present, it has entered a period dominated by HFC refrigerants, and its main representative product is HFC-134A.

Although HFC-134A has an ozone depletion potential (ODP) of 0, it has a high greenhouse effect (GWPu003d1300) and a long atmospheric life span. Large-scale use will cause global climate Warming has also entered the lifespan countdown stage.

Since 2011, HFO-1234yf, developed by DuPont and Honeywell, has been used as a single refrigerant refrigerant and has excellent environmental parameters, GWPu003d4, ODP u003d0, Life Cycle Climate Performance (LCCP) is lower than HFC-134a, atmospheric decomposition products are the same as HFC-134a, and its system performance is better than HFC-134a. It has been accepted by Western European automobile manufacturers and gradually promoted.

At the same time, relevant traffic control measures have had a great impact on the transportation of chemicals, and the restrictions and controls on the three super markets have caused a substantial increase in logistics costs; After entering September, most manufacturers will carry out internal equipment maintenance. The start-up load of the factory has dropped, resulting in a serious shortage of inventory, short-term supply shortages, and once again raising market supply prices; the recent increase in the price of raw materials has been intensified, involving various types of raw materials in many fields The rise of R134A has caused a significant increase in refrigerant products related tanks, valves, cartons, etc.;

Since New Year's Day, the price of R134A has increased slightly, 33000-33500 /Ton, it is expected that there is still room for price increase under the influence of various factors, or it may continue until the end of the second quarter! The basic composition of refrigerant cost The cost composition of a tank of refrigerant is roughly divided into several parts: R134a raw materials, filling fees and losses, tanks, valves, outer packaging and printing, logistics, transportation and warehousing, management and operating expenses, taxes and reasonable Corporate profits, etc.

The general R134a market is divided into two categories: first-class products (content ≥99.5%); superior-grade products (content ≥99.9%). Take the superior-grade products as an example. The cost of raw materials has reached 33500/ton, plus other necessary expenses, the cost of a can of ordinary packaging/brand refrigerant is basically more than 11 yuan/can. I would like to remind everyone that when buying refrigerants, you need to confirm that the quality is guaranteed and then look at the price. Do not blindly pursue low prices.

In order to meet the upcoming demand for refrigerants, we have made full preparations for everyone. Not only the product quality is guaranteed, but the price is in place in one step. Hope that the majority of maintenance business friends seize the opportunity and don't miss it!
