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…

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…

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…

RefrigerantRefrigerant costs fell slightly last week, the market price stable operation. The average price of R22 is 20000 yuan/ton, the same as last week; R32 mainstream trading price reference 14500 yuan/ton, the same as last week; The average price of R125 is 26,000 yuan/ton, the same as last week; The average price of R134a was 24,000 yuan/ton, unchanged from last week.R22: At the raw material end, the market price of trichloromethane decreased slightly; The supply end, the overall operation is normal, the enterprise production of self-use of raw materials mainly, less foreign sales; The demand end, the terminal market is gradually entering the peak season of demand, the downstream procurement enthusiasm increases, the overall price rises after maintaining stability.R32: At the raw material end, the market price of dichloromethane rises and maintains stability; At the supply end, some manufacturers stop for maintenance, and the supply is slightly strained; At the…

Mega Clima Nigeria held on July 11-13, 2023. Quzhou Rongqiang Chem attented this exhibition.

Pakistan International Air Conditioning & Refrigeration Exhibition 2023 opened on June 8 at Karachi Convention & Exhibition Center. The exhibition is sponsored by the Pakistan Refrigeration Association and is the largest and most popular HVAC refrigeration exhibition in Pakistan. Quzhou Rongqiang Chem attented this exhibition.

The 7th EGYPT International HVAC Refrigeration and Ventilation Exhibition (HVAC-R EGYPT EXPO) in 2023 opened on May 17 at the Egyptian International Exhibition Center in Cairo, for a period of 3 days, co-sponsored by the Egyptian Refrigeration Association and Cairo Expo Exhibition Group, is the largest and most professional international air conditioning and refrigeration exhibition in Egypt. Quzhou Rongqiang Chem attented this exhibition.

From April 7 to 9, 2023, the 34th International Refrigeration, air conditioning, heating, ventilation and Food Refrigeration Processing Exhibition (referred to as “2023 China Refrigeration Exhibition”) was held in Shanghai New International Expo Center.

At the raw material end of R32, the market price of dichloromethane is weak and stable, while the price of anhydrous hydrogen fluoride is strong and the cost support is strong. At the supply end, some manufacturers stop for maintenance, and the supply shortage continues; On the demand side, R32 market enters the traditional peak season, domestic and foreign trade demand picks up steadily, and market price is firm and stable.

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)
