On November 3, HCFC-22 was replaced by the room air conditioner industry jointly sponsored by the MEPC Environmental Protection Cooperation Center, the United Nations Industrial Development Organization, the United Nations Environment Program, the United Nations Development Program, the German Agency for International Cooperation and the China Household Electrical Appliances Association Technology International Exchange Conference and China Household Electrical Appliances Technology Conference in 2017 Air-conditioner Technical Branch was held in Hefei. More than 200 representatives from international institutions, industrial organizations and research institutes, as well as related enterprises of machine, spare parts and industrial chains of room air conditioners participated meeting.
R290 Promotion into the second phase of air conditioning industry performance key
Currently, the global phase-out of ODS-containing hydrochlorofluorocarbons (HCFCs) and the room air-conditioner industry as a large consumer of HCFC-22 under the Montreal Protocol is also accelerating the phase-out and substitution of such substances. Is the world's largest producer of room air conditioners, China's room air conditioner industry, compliance progress and alternative technology choices have attracted the attention of the international community.
In the first phase of compliance, China's room air conditioner industry successfully achieved the goal of 10% phase-out by the end of 2015, the industry out of a total of more than 11,000 tons of R22. After careful selection, China's room air conditioner industry identified in the refrigerant replacement technology (GWP) and chose R290, a low-carbon and environmentally friendly hydrocarbon-friendly refrigerant, as next-generation refrigerant.In the first stage, the entire industry completed 19 290 air-conditioners and 4 R290 compressor production line transformation, the formation of R290 air conditioning production and market-oriented capabilities, and carried out the relevant standards of revision, technical exchange and installation and maintenance training.
In his speech, Xiao Xuezhi, deputy director of the MEPC's Environmental Protection Cooperation Center, highly praised the performance of the room air conditioner industry in the first phase of our country's performance. At the same time, he also emphasized that the 19 th National Congress of the Communist Party of China He proposed a series of new changes, new ideas, new requirements, new goals and new deployments.He urged the room air conditioner industry to effectively implement the "Montreal Protocol" and the relevant international conventions , Contribute to global ecological security.

In December 2016, the 77th Executive Committee of the Multilateral Fund for the Montreal Protocol approved the second phase of the HCFC phase-out management plan for the room air-conditioner industry submitted by our country and in March this year, the United Nations Industrial Development Organization, the Italian Ministry of the Environment, Environment and Marine, China MEPC Environmental Protection Cooperation Center and China Household Electrical Appliances Association jointly issued the second stage HCFC phase-out management plan of China's room air conditioners and domestic heat pump water heater industry in Shanghai.
At this meeting, Zizhi Feng, Deputy Director of the Third Cooperation Center for Environmental Protection of MEP Environmental Protection Department, elaborated on the Phase II phase-out management plan. By 2020, China's room air conditioner industry and domestic heat pump water heater industry need to eliminate 26,145 tons HCFC consumption, achieving the target of 45% reduction at baseline, which is ahead of the original 35% phase-out target.

'Room air conditioner industry, the second phase of the reduction target of 45%, can be said that time is tight task, which requires enterprises to be fully prepared.' Xiao Xuezhi stressed that the current implementation of our Montreal Protocol's priority task is to accelerate the elimination of HCFCs, at the same time we should study, analyze and discuss the impact of the Kigali amendment on the room air conditioner industry in our country.
In October 2016, countries in the world reached the Kigali amendment to the Montreal Protocol in the capital of Rwanda. The amendment clarified the timeline for the reduction of HFCs. HFC refrigerants including R410A and R32 were included Control range.
Xiao Xuezhi stressed that although our country has not banned the use of R410A, R410A will not be used as a guide and encouragement. 'R290 route from the environmental protection we think fully in line with the direction,' Xiao Xuezhi clearly stance, 'who actively adopt the R290, we Who supports?
According to Zhong Zhifeng introduction, the second phase of China's room air conditioner industry will transform at least 20 R290 room air conditioner production line with 3-4 R290 compressor production line. He further said that the transformation of production lines, improve the standard system, R290 air conditioning market, the maintenance industry Training center construction and local capacity-building projects will be the focus of the second phase of work.
We also encourage everyone to do more research in the field of technology and do more research on intellectual property. In addition, we continue to actively participate in international standards (revisions) and make the international community aware of China's concerns, "said Chung Chih-feng.
The international community has great hopes for China's R290 air conditioner
In fact, R290 is not only the choice of China's room air conditioner industry, but also the trend of the world.United Nations Industrial Development Organization Montreal Protocol Director Ole Nielsen said that at present, Algeria, Tunisia, Saudi Arabia has been carrying out the R290 air conditioning production line In addition, a lot of countries are interested in R290, and more and more countries are carrying out capacity building for R290 air conditioners.

According to Ole Nielsen, the R290 is a very good refrigerant especially for the R290 at high temperatures, and the safety risk of the R290 is manageable despite safety concerns.
German International Cooperation Agency official Bernhard Siegele introduced R290 technology in the global application and promotion case, said that at present, R290 refrigerant worldwide has been more widely used, the global demand for R290 air conditioning continues to grow in India , The local room air-conditioner manufacturer Godrej has successfully installed more than 350,000 sets of R290 air-conditioners, but so far no accident with an R290 air-conditioner has occurred.

'The whole world is waiting for China's R290 air conditioner.' Bernhard Siegele placed great expectations on China's room air conditioner industry.
According to Hu Shaofeng, senior project officer of UNEP, due to the flammability of the R290 itself, the installation and maintenance of the R290 air conditioner is still a challenge, so UNEP will work with China's industry associations and industry to formulate some R290 air conditioning installation and maintenance of good practices and technical specifications and standards to ensure the proper use of R290 refrigerant and compliance installation and maintenance operations.

At present, international standards have imposed very restrictive limits on the charge of flammable refrigerants and become a 'stumbling block' on the market of R290 air conditioners. At this meeting, senior lawyers from the United States Environmental Investigation Agency (EIA) International Policy Consultant Mark W. Roberts, introducing the revision of US UL standards, encouraged China's room air conditioners to actively participate in the revision of global standards so as to ensure that the new standard will not be the global trade barrier for R290 air conditioners manufactured in China.

With the help of many channels, the selection of room air conditioner industry in our country R290 is in line with the well-being of all mankind. Therefore, the choice of Chinese industry has gained more and more support from the international community.
'We are ready to provide funding to businesses to help them move to R290 to help them with capacity building and marketability of R290 air conditioners.' 'Ole Nielsen said that R290 technology could be rolled out globally only if all worked together.
Dr. Hong Yun, program manager of the Beijing office of the United Nations Development Program also said that UNDP is willing to cooperate with China's room air conditioner enterprises to jointly promote the application and promotion of R290 technology.
'At present, we also have funds to adjust and mobilize industry plans and set up special projects to encourage manufacturers, distributors to install, train and market (R290 air conditioning),' said Xiao Xuezhi.
