• R32 Refrigerant: Serious Excess Capacity, Is About To Enter a New Development Cycle

    At present, most high fructose corn syrup refrigerants face the severe test of excess capacity, especially R32 refrigerant. “Sell at a loss to win sales” is a common tactic used by R32 refrigerant companies in the battle for quotas. Entering 2023, the battle for R32 refrigerant quota is over, and production and consumption are about to be frozen. How to develop in the next stage? Worth the attention of the industry. After several years of rapid expansion in the home air conditioning industry with its low price advantage, the R32 refrigerant is now firmly in the forefront of home air conditioning refrigerants. However, the industry for R32 air conditioning market proportion statistics are slightly different. Data provided by Wang Ming, an industry online fluorochemical analyst, shows that in the household air conditioning market in 2022, R22 models will take up less than 1% of the market, R410A models will take…

  • The Significance of Supercooling and Superheat in Refrigeration System

    The so-called “supercooling” is to recool the saturated liquid after condensation through a device (such as the supercooler) and methods (or measures), so that its temperature is lower than the saturation temperature under the condensing pressure, which is called supercooling. Comparing the temperature of the liquid before and after supercooling, the difference is “degree of supercooling”.Supercooling is to make the refrigerant liquid before throttling reduce the flash gas produced in the throttling process, reduce the specific volume of the flash gas, and improve the unit cooling capacity; At the same time, it also improves the superheat of the return air, which has certain advantages to protect the compressor from wet stroke operation.In the larger refrigeration system, in order to reduce the refrigerant liquid temperature into the throttle valve, reduce the flash gas generated in the throttling or throttling, improve the refrigeration efficiency, in the process design after the reservoir (the…

  • Refrigerant R290:The Moment of Highlight

    R290, or propane, is a natural hydrocarbon refrigerant that can be obtained directly from liquefied gas. In contrast to synthetic refrigerants like freon, natural refrigerant R290 does not contain chlorine atoms in its molecules, so it has zero ODP and does not damage the ozone layer. In addition, compared with HFCS, which also do not damage the ozone layer, R290 has a GWP value close to zero, which does not contribute to the “greenhouse effect”.R290, which is perfect for both GWP and ODP, has been unable to reach the mainstream market due to controversy over its classification as an A3 combustible refrigerant.Happily, this barrier has loosened in 2022.In May 2022, IEC said on its official website that the draft IEC 60335-2-40 ED7, Special Requirements for Heat Pumps, air conditioners and dehumidifiers, was unanimously approved. This means that the IEC standard has been unanimously approved to increase the charging limits for…

  • Meet the Peak Season Refrigerant Boom Higher Upstream Fluorite Prices

    Recently, affected by the recovery of demand and the change of mentality of manufacturers, the refrigerant industry prosperity is higher. Taking third-generation refrigerant R32 as an example, industry data show that the current price offered to air conditioning manufacturers reaches 15,000 yuan/ton, up nearly 30% year on year. The bargaining power of refrigerant manufacturers is significantly improved, and the industry profit is quickly restored. Industry insiders said that last year in order to compete for three generations of refrigerant quota, there is a price inversion, this year the enterprise no longer loss sales necessary, expected to improve. Among the main upstream raw materials for refrigerant, the price of fluorite took the lead in rising in March, reaching 3100 yuan/ton, which is at a relatively high level. The industry is expected to fluorite enterprise overall gross profit year-on-year, quarter-on-quarter have increased. (Article source: Cailian)
