Refrigerant and upgrading caused by air-conditioning, standards and regulations revised new product not listed. Industrial and commercial refrigeration industry has spearheaded hydrogen elimination refrigerant CFCS (HCFCs). On December 12, four companies such as gree, shield security environment, raised $18.05 million in funding, to refrigeration and air-conditioning equipment production line 10, promised to eliminate 3064 tons of refrigerant hcfc-22 (also called R22). R22 is our country at present are the largest and the most widely application scope of the refrigerant. In July 2011, China submitted by polyurethane foam, foam extrusion polystyrene (XPS), the room air conditioner, industrial and commercial refrigeration, refrigeration maintenance industry first stage HCFCs are out of the plan in the Montreal protocol for the 64th time through multilateral fund board, and get a $265 million project. & other; We encourage our enterprises to adopt more environmentally friendly alternative technology, in the project when the choice, we have a tendency of is. Throughout the &; The environmental protection department of environmental protection cooperation center project officials Zhong Zhifeng told reporters, the room air conditioning industry one of the first renovation project plan signed in January of 2013. However, the use of new environmental protection refrigerant air conditioning, from production to market still has some way to go, to be related to the improvement of the standard. An enterprise\'s R290 (commonly known as propane) air conditioning production line inspection up to now, failed to list at home, some exports. & other; Companies that is completely passive, no revision of relevant standards and regulations, market is not acceptable. Throughout the &; Thermal energy research institute of tianjin university explained a horse too. Technology path clear China since 1991, signed the Montreal protocol, the implementation work has entered the stage of full out HCFCs. According to the decision, China HCFCs output and consumption must be freeze in 2013 to 2009 and 2010 the average baseline, cuts to 10% by 2015, 2020, a 35% cut in, cut by 67.5% in 2025, to 2030 except a small amount (2.5%) used for refrigeration maintenance, fully eliminated. Industrial and commercial refrigeration industry the first phase out HCFCs8450 tons. Montreal multilateral fund will provide $61 million in aid for industrial and commercial refrigeration industry, including $53 million for the enterprise production line modification, $8 million for efficient new refrigerant property research, three contract is signed, the first signed total of $18.05 million. Signed the first batch of enterprises have been born. On December 12, international cooperation of environmental protection environmental protection center held a signing ceremony, for enterprises in zhuhai gree electric appliances co., LTD., zhejiang shield artificial environment co., LTD., nanjing day and zhejiang commercial air-conditioning equipment co., LTD. Project adopts zero ozone depletion QianNengZhi QianNengZhi (ODP), low global warming (GWP) of alternative technologies. Gree get $14.66 million bailout fund, to apply for the 5 production lines, product type involving ChanYuanJi, more online, cold water machine, etc., for industry and commerce, R410A, R134A has a alternative route is R32, promised to eliminate 2607 tons of HCFCs. Shield Ann environment involving the unitary air - conditioner, small and medium-sized water chillers two production lines, using R32 alternative refrigerants of R22. In fact, the replacement of refrigerant is a worldwide problem, the main using R290 replacement of household air conditioning, commercial, industrial, mostly choose R32, a small number of using R410A, CO2 and NH3. & other; There is no perfect alternative refrigerants, now select the relatively better. Throughout the &; China refrigeration and air conditioning industry association technical personnel explain, R290 have flammability, R32 have flammability, R134A has a relatively mature alternative technology and higher GWP index of R410A. In Zhong Zhifeng view, in view of some more specific alternative technologies are clear. & other; VRF can use R410A, chiller, centrifugal units on the basis of different equipment difference between alternative technologies. Throughout the &; Will continue to push production line reconstruction project. It is necessary to reform the standard Room air conditioning industry is the first time, will transform 13 R290 production line, production line, 10 R410A out HCFCs is expected to more than 10000 tons. In R22 alternative directions, China household electrical appliances association first hydrocarbon working substance as refrigerant R22 alternative technologies, and R410A as transitional alternative technologies. Actually, midea, gree, haier, chigo, TCL and other enterprise is devoted to the study of the environmental protection refrigerant. In July 2011, the United States about R32, R290 and R161 three new environmental protection refrigerant technology and application of key technology research project formally approved identification. Gree the same month, the world\'s first demonstration of R290 fission air conditioning production line of formal completion, acceptance by sino-germany joint panel between the two countries. In August 2012, won the global environmental protection refrigerant air conditioning gree R32 first VDE certification. Remarkably, the using new environmental protection refrigerant air conditioning products face the embarrassment of not listed R290 air conditioning is so. Product need to pass 3 c certification, but not yet implemented such products safety standards, no certification basis. & other; This involves the standard question, is all enterprise production need to be solved. Secondly, is the issue of security protection, air conditioning factory is a semi-finished products, the installation link to eliminate risk factors. Throughout the &; The Chinese electrical appliances research institute electrical division engineer Hu Zhijiang analysis, R290 because of its flammability, support safety standards need to do a lot of experiments, the current product standards is limited to the lowest concentrations of combustible. According to the requirements of the existing security and R290 and R600 flammable refrigerants are not allowed for the related categories. Standards at present, the refrigerant has \"household and similar electrical appliances safety special requirement of heat pump, air conditioner and dehumidifier (GB4706.32-2004), the cooling and heating with mechanical refrigeration system safety requirements\" (GB 9237-2001) and refrigerant number method, and security classification (GB/T7778-2008). & other; Government departments are to make some measures to make up for the blank place. Throughout the &; Zhong Zhifeng, said some certification experiment reform is in progress. The GB4706.32-2004 revision of the new standard will come into effect on May 1 next year, the new join flammable refrigerants in identification, transportation, installation, storage, filling the safety of the operation and use, increase of flammable refrigerants appliance installation and maintenance requirements. Wu Wenxin beautiful household air-conditioning division President has said that once the national relevant laws and regulations, can complete the new environmental protection refrigerant in the first place of beauty in the replacement of the products.
