Face refrigerant substitution problem, the rise of R290 air conditioning in!

2019 - 04 - 02 at present, most of the developed countries have basically completed the HCFCs replacement work, in the developing countries of China will stop the use of HCFCs in 2030. On January 1, 2019 formally implemented, amendment of Kigali marks the HFCs out into the countdown. This means that the household air conditioning industry will r410a and R32 as the transitional alternative technical route, R290 ( Propane) As the main alternative route direction is clear. Back home air conditioning refrigerant replacement process industry, from HCFCs refrigerant R22 to HFCs refrigerant R410A ( GWP value of 2088) And R32 ( The ODP is 0, GWP value of 675) , the former has been cut for many years, in the use of household air conditioner has entered the countdown, which both have a foothold in household air conditioner industry R410A, or nearly two years the rise of R32, in front of Kigali amendment has been implemented, is just a transition role. When it comes to R32 although have made it clear that the future will join the list out, but still get home air conditioning factory of reason, meilan chemical industry officials said: & other; Nearly two years, the downstream demand increase and the influence of R32 price advantage prominent, the fluorine chemical refrigerant manufacturer is even chemical companies increased the R32. ” Although R32 and there have been many refrigerant factory as well as the use of air conditioning plant, is only a household air conditioning replacement in the history of short-term & other March & throughout; 。 In fact, whether the refrigerant interviewed enterprises, or the whole business is very clear R32 in Kigali amendment of policy development prospects will be very bleak, but given the short-term interests, or in the active layout. R32 as HFCs material, however, is ultimately a transitional alternative. Looking for more environmentally friendly technology and mature alternative to the pursuit of the household air conditioning will be the industry will continue to follow unswervingly. As things stand, hydrocarbon refrigerants R290 as the main alternative route technology selection has been very clear. And household air-conditioning industry in China, under the push of R290 air conditioning in the production line construction, safety evaluation, standard certification, technical research and development, installation, training, promotion, etc, has accumulated rich experience. On October 31, 2018, household appliances and technology of China in 2018 as the conference room air conditioner industry 22 alternative technologies international exchange and air conditioner on the branch of professional technique, the ministry of environmental protection the international cooperation center project officer Li Xiaoyan summary of room air conditioner industry HPMP said: the first stage of R290 air-conditioning to promote progress & other; In the first stage, the HPMP room air conditioner industry in China has accomplished the transformation of 26 production lines, including 18 R290 air-conditioning production line and three R290 compressor production line. HPMP the second stage, the industry will continue to conduct of R290 air-conditioning production line modification, such as technology research and development work. Among them, the transformation of production lines including 20 R290 air-conditioning production line, 3 R290 household heat pump production line and 3 ~ 4 R290 compressor production line. And R290 air conditioning market by the national related departments with the China association for household appliances as the performance of the second stage to focus. And, more importantly, we research in R290 refrigerant distribution, low GWP technology research, to promote marketization of R290 air conditioning, update and perfect the standard system has achieved many breakthroughs. ” She with R290 market into the case, said further & other; So far, gree 243 units have been installed in shenzhen university R290 air-conditioning, beautiful 1096 units have been installed in jiaxing nanyang polytechnic R290 air-conditioning, haier in the Beijing office building installed 60 sets of R290 air conditioning, changhong was installed in the southwest university of science and technology 299 R290 air-conditioning machines, 4517 sets of TCL is installed in places such as zhongshan R290 air conditioning. ” Over the years controversy about the safety of R290 used in household air conditioner at home and abroad, some industry insiders responded that theory, the safety of R290 has been verified in the experiment. From the perspective of practice, Godrej company is one of the four air conditioning manufacturers of India, has 100 years of development history, since 2012 since the sales of R290 air conditioning, so far has accumulated sales of 600000 units, and get a good market feedback. In addition, in the light quotient R290 also got a quick freezer applications. Changhong Huayi Compressor Co. , Ltd. , marketing director last in an interview with reporters said that in 2018 by Huayi as R290 & in the field of trade and other A full-blown & throughout; Years, the internal data shows that R290 products industry growth of close to 100% in the first half of the year. Besides R290, HFOs based raw materials mixed refrigerant is household air-conditioning industry one of the alternative direction in the future. HFOs under the cost problem, want to realize the application in household air conditioner is still facing a big challenge. Honeywell material characteristics and technology group, high-performance materials fluorine products business, general manager of Asia Pacific Yang Wenqi that & other; Honeywell in this area is still in the development process, there is no mature solution. ”
