The hydrocarbon market increasingly mature R290 applications continue to expand

in response to the global challenge of climate change, under the objective requirement of hydrocarbon refrigerants in the international community is becoming more and more high, especially the Montreal protocol amendments to Kigali, hydrocarbon refrigerants to obtain rapid development accelerator. On April 10 - 11, the room air conditioner industry R290 refrigerant application design, manufacture and installation of the international seminar held in ningbo, independent environmental protection organizations the environmental investigation agency ( EIA) Lawyers, international policy consultant Mark W. Roberts, introduction of hydrocarbon refrigerants at the meeting in the United States commercial refrigeration field application and trend that future hydrocarbon refrigerants will be rapid development in China, especially in the field of room air conditioner industry and light commercial refrigeration. The independent environmental protection organizations the environmental investigation agency ( EIA) Lawyer international policy consultant Mark W. Roberts, in order to stop global warming, countries around the world are committed to cut greenhouse effect QianZhi ( GWP) Gas, in October last year reached the Montreal protocol amendments to Kigali, has been clear about the schedule of level around the world to cut greenhouse gases HFCs, the developed countries should cut down the consumption and production of HFCs since 2019, to cut the HFCs usage after 2036 to 15% of its basic value within the development, while developing countries should freeze HFCs consumption and production since 2024, since 2029 began to cut, to cut the HFCs usage to its basic value after 2045 to less than 20%. Kigali amendment agreed upon, objectively for low carbon environmental protection created an opportunity for the development of hydrocarbon refrigerants. A large number of studies have shown that hydrocarbon refrigerants R290, R600a and as refrigerant R22 with similar or slightly higher critical temperature, the two kinds of refrigerants under the environment of high temperature has better performance than HFC and HFC mixtures, R290 high temperature zone of the COP/energy-efficient performance is good. 'Hydrocarbon in many small and medium-sized residential and light commercial equipment was proved to be safe and refrigerant, especially in the independent commercial refrigerators and freezers, vending machines, water cooler, ice maker and room air conditioner. 'Said Roberts. Hydrocarbon refrigerants have been widely used in the United States. Santa Clara, California, healthy Foods, Whole Foods using R290 / co2 commercial system, the system using R290 refrigerants condensation of carbon dioxide, so as to achieve the refrigeration effect, the use of hydrocarbon refrigerants, that allows the system to eliminate all the direct emissions of greenhouse gases, to avoid the over 7000 tons of co2 equivalent emissions. Chain, H - 2013, the United States E- B in Austin, Texas has opened a large food city, the city he is adopted, inc. ( Hussmann) Design of R290 refrigeration system, the system design service life of up to 15 - For 20 years, as a result of R290 refrigerants, the system will be able to reduce 1556 metric tons of co2 equivalent emissions. Project in the system running, the documents show the system energy efficiency than the traditional refrigerant system is increased by 79%. Have over 1800 stores in the United States city of large-scale integrated Target announced that will be used in all the new independent type of air-conditioner R290 as refrigerant, from January 2016 Target all stores in 2200 BTU/hour power of independent type of air-conditioner will not using HFC substance as refrigerant, 6 - in the future Eight months, Target new store will adopt R290 as its independent type of air-conditioner refrigerant. In the past two years, the True refrigerator/freezer manufacturer, has its food service and retail food in the refrigerator/freezer about 80% from HFCs into R290 refrigerants, its average before can effect comparing with HFC refrigerants R290 products ranging from 15% to 25% higher than that of products. Roberts said that R290 combustible and the fact that are widely used as a fuel has aroused people concerned about the security of this kind of material used as refrigerant, but in 2013, 'international journal of refrigeration, according to a study published in the ignition of R290 ice cream freezer opportunity less than 0. 001%, another study shows that using the ice cream freezer of refrigerant R290 compared with the traditional equipment, security, reliability and performance without any change. Have been used for over 1. 5 billion consumers around the world using hydrocarbon refrigerants of refrigerators and freezers, history of the use of hydrocarbon refrigerants in Europe for more than twenty years, but the bums and did not increase the risk. In fact, the relevant policies and regulations are also gradually loosening, allow the hydrocarbon refrigerants R290 used more widely. The significant new alternatives policy ( 提前) Under the regulations 19 through new alternatives, allowing R290 used in domestic refrigerators, freezers, vending machines and room air conditioner products, the U. S. environmental protection agency also allows R290 used in commercial ice machine, cold water machine and low temperature system. Underwriters laboratories ( UL) Began to consider raising hydrocarbon refrigerants in household refrigeration equipment and self-contained air-conditioning filling quantity limit. Not only in the United States, hydrocarbon refrigerants in the world is also the trend of The Times. Roberts believes that over the next 15 years hydrocarbon refrigerants will be rapid development in China, especially in the field of room air conditioner industry and light commercial refrigeration, predicts 2020, the application of hydrocarbon refrigerants in the Chinese room air conditioner industry proportion is expected to reach 10%, to 2030 the ratio can reach 50%.
