Refrigerant R290 application in light commercial freezer

compared with category of air conditioning, the refrigerator category instead of refrigerant work earlier, in 2007, is now over. It is reported that about 90% of the market in our country the refrigerator are using R600a as refrigerant, as long as less than 10% of the freezer to use everything. According to China's household electrical appliances association, deputy director wang lei, choose everything as refrigerant commodity, before 2013, the first is to use in the refrigerator freezer and exports, is now the primary cooler. In recent years, some light commercial ( Hereinafter referred to as the light quotient) Beginning of air-conditioner use of R290 instead of everything.

huayi tightening machine co. , LTD. , is pushing for light commercial tightening machine, when it comes to the use of light quotient of air-conditioner professional refrigerant. Huayi tightening machine co. , LTD. Director of mall last know more. He said: 'now light quotient freezers first choose everything and r404a as refrigerant, R507, CO2 R242, R290, there are a few use. At the light commercial freezers category, everything is more advantage in small and medium-sized refrigerating capacity of goods, and small and medium-sized refrigerating capacity use everything more goods. R404A in large capacity ( Such as 14 HP HP, 16, 18 HP, HP 21 and 23 HP, etc. ) Light on the business of air-conditioner using the advantage of more significant, so big refrigerating capacity using R404A more goods. From these two kinds of refrigerants in light quotient of air-conditioner use scale, everything: R404A are 6:4 or three, larger ratio of everything. '

' 2015 ~ 2017, R404A and everything is still used in light quotient of air-conditioner category of refrigerant in the lancang river. 'Last very sure to tell' appliances 'reporters,' advantage lies in the capacity of R290 cover area wide, fast freezing and refrigerating capacity under equal volume is bigger. Light quotient of air-conditioner category in the future application of mass and increase agility is refrigerant R290 R290 will be following the everything and the third largest river after R404A refrigerants, the industry has now clearly define it as the third pole of refrigerant commercial. As to when to large-scale use of certain point in time, still needs the industrial chain upstream and downstream reach consensus and actively cultivate the market. '

China's household electrical appliances association, deputy director of wang lei is very bullish on R290 in freezers category using the vision. She thought, filling of R290 air-conditioner refrigeration power, higher cooling can better applicability, suitable for low, medium and high back pressure condition, energy conservation and environmental protection. Now, the stars, companies such as haier, Snow White has been produced using R290 freezers.

dongyue group assistant general manager of the refrigerant skills base nature conservancy council pointed out that the light quotient of air-conditioner may be self-contained system as well as some small filling quantity of refrigeration equipment can use of R290. Due to the equipment leakage of refrigerant maybe sex is small, the security risk is very low.

'from the point of use effect, eer everything and R290 high R12, GWP value lower than everything and R12, air-conditioner is a closed system, with R290 many skills problem exists in the air conditioning use, does not exist in the freezer. For equipment repair, freezers if using R290, does not need external piping, reduce many unnecessary danger. So R290 used in air-conditioner category has the broad vision, perhaps even more simple than the use of air conditioning category and end. 'Foreign cooperation base of environmental protection environmental protection officials said.

about R290 in light quotient of air-conditioner category using status, last said: 'compared with using R290 air conditioning, use of R290 light quotient of air-conditioner industrialization leading companies are now beginning, the use of R290 light quotient of air-conditioner with tightening machine also has in some professional completion of industrialization. Haier, aucma, hisense kelon, HaiRong, stars and other manufacturers are now beginning batch supply using R290 light quotient of air-conditioner. Now, the use of R290 light quotient of air-conditioner with tightening machine two of the primary production business is of huayi austerity and blah. Huayi crunch, for example, huayi tightening machine co. , LTD. Using R290 commercial freezer with tightening machine now has a specialization, standardization and industrialization of talent, in period of cooling capacity, energy efficiency, low working condition of high back pressure more use of copper and aluminum wire cover, huayi crunch now over all planning. In order to have R290 industrialization to squeeze machine, huayi deflation has been a lot of investment in the software and hardware, and built in December 28, 2014 professional beat new commercial austerity wit can produce line. On the depth and extent of R290 commercial use, huayi squeeze all preparation has been completed. 'According to' electric 'reporter understanding, abroad, freezers of R290 used very widely. In Europe, can use R290 all independent type of air-conditioner. '

although using R290 freezers and industrialization of tightening machine has been finished, but now all stores in our country has not rolled out. Light quotient of air-conditioner companies have long known that the superior performance of R290, but tightening machine company always can't end of R290 tightening machine series bulk supply, the market for a long time in the stage of a few use.

head thought about international cooperation base of environmental protection environmental protection, prevent R290 mass on the air-conditioner use elements of the first is a professional guide. 'Very few people know that R290 can effect comparing everything is high, we may just accustomed to use everything, for the new refrigerant is hard to bear. If China's increased investment in this respect, with some skills on the common question that followed the tightening machine company and freezers of R290 recognition gradually, using R290 tightening machine development will be faster. In fact, from the beginning of 2014, the use of R290 air-conditioner sales are now shows a tendency of increase rapidly. '
