China's air conditioning enterprise go out why blocked? International environmental barriers reversed transmission refrigerant innovation

for China ZhiLengYe, choose what kind of material instead of widely used in the refrigerant HCFCs, already can not damage the ozone layer, but also in the economic cost and efficiency to achieve balance, is the industry must attack the problem.

after the ozone safer hydrofluorocarbons ( HFCs） , was seen as the ideal replacement. But the only fly in the ointment is that HFCs greenhouse effect is extremely high. Experts think, has been the Kyoto protocol as a HFCs of greenhouse gases, and the climate warming effect is far better than the same amount of carbon dioxide. Therefore, also some people called it 'super' greenhouse gases.

in October 2016, to cut the HFCs it adopted the amendment to the Montreal protocol Kigali. According to the agreement, the three reduce use HFCs, the United States and other developed countries will first reduce the dosage of HFCs since 2019; More than 100 developing countries, including China, and should be started in 2024 to reduce the dosage.

Hu Shaofeng to gain new reporter pointed out that with the freezing of ozone-depleting substances work quite progress, the focus of the global ozone action also began to shift, 'in terms of the status quo, if we do not consider the factor of climate change, ozone layer of the work is over, actually. , including China, the current global ozone action is around how to promote better to slow climate change. '

he described, mainly for the regulation of ozone-depleting substances' Kigali amendment ', can be as a greenhouse gas HFCs equally in limit control list, 'through the ( Ozone protection and climate change) Two areas ', as a milestone.

'Kigali amendment', means that China's industrial and commercial ZhiLengYe will face cuts HCFCs and HFCs at the same time two generations of the challenges of the refrigerant material. New reporter zhang zhaohui tell fortune, however, had prepared for the industry, 'we are doing protocol phase one, have already realized that HFCs will be eliminated sooner or later, but at that time were not definite time node and cutting task. '

according to zhang zhaohui, all existing alternative refrigerants of HCFCs matter isn't perfect,' such as the natural working medium carbon dioxide, its high pressure compressor work; Ammonia refrigerant flammable, toxic; Hydrocarbon refrigerants are flammable, explosive. '

but as through amendments to Kigali, the international community has increasingly clear, the selection of alternative refrigerants direction that is choosing ozone-depleting QianZhi and greenhouse effect QianZhi substitute for' double low ', 'we are in a selected direction under the defect management, with technical means to make up the defects of alternatives. '

zhang zhaohui, acknowledges that both technology and capital, the refrigerant replacement work is the process of international cooperation,' cannot be separated from the exchange of experience of the experts. 'But as early as more than a decade ago and has been successful enterprises' going out 'of China's air conditioning, also because of the environmental technical barriers, suffered a lot in Europe and the United States and other developed markets.

as the performance of the emissions reduction requirements related to the Kyoto protocol, the eu in 2015, the official start of the implementation of HFCs fluorinated greenhouse gases such as new rules 'F - in the European Union Gas regulations '. According to zhang zhaohui, this means that China produces air conditioning to the eu market, must first obtain the corresponding on the basis of the original market share refrigerant quotas; For equipment after the entry into the eu, according to the quota to it again again refrigerant charging standard.

as a result, Chinese enterprises not only cut a piece of 'industry chain'; Because the past is European and us companies dominate the market, trying to get the quota, China's enterprises is no longer competitive.

more independent research and development of alternative refrigerants, is China's breakthrough green trade barriers in developed countries a feasible way. Zhang zhaohui said, because many Chinese companies are still mainly 'price competition' in the global market, investing in research and development is not high; China at the heart of the new environmental protection refrigerants development ability is still weak. But he also stressed that 'Chinese air-conditioning and chemical industry, its investment in r&d is rising year by year, just see results need a process. '
