On April 15, the 113th session of China import and export commodities fair (also known as \"Canton fair\") in guangzhou pazhou international convention and exhibition center opened as scheduled. \"Low carbon environmental protection\" is the theme of in recent year, there has been concern, one of the biggest attraction of this year is the new refrigerant air conditioning. New refrigerant air conditioning refers to through the use of new environmental protection refrigerant R290 and R32, alternatives to traditional refrigerant R22, and thus to minimize the destruction of the ozone layer and put an end to the greenhouse effect of the new products. Canton fair site, gree electric appliances independent research and development of new refrigerant R290 R32, air conditioning, because of the low carbon life advocated by merchants from all over the world attention. It is understood that R290 commonly known as propane, is a pure natural green environmental protection refrigerants, no ozone depletion, the greenhouse effect value close to zero, using R290, can reduce more than 70% of the filling volume. With a 1.5 amount of cold air conditioning as an example, the freon filling volume is about 1.2 kg, if use R290 can decrease to less than 0.4 kg, equivalent to 1799 kg reduce carbon dioxide emissions. Gree refrigerant R290 environmental protection air conditioning in September of 2010 research and development success, and through the European safety certification, Germany VDE certification authority, access to European markets here. On July 14, 2011, the world\'s first pair of hydrocarbon refrigerants R290 (commonly known as \"propane) split type air conditioner demonstration line officially completed in zhuhai gree electric appliances, and smoothly passed the china-germany bilateral joint site acceptance of the panel. It marks the industry watches R290 refrigerant air conditioning implement production formally. The gree R290 environmental protection air conditioning has become very popular in the overseas markets such as the maldives, Germany\'s product. Country li ganjie, vice minister of environmental protection has said, \"as room air conditioner refrigerant R290, ozone depletion, climate warming, is China\'s industry of global environmental problems, such as a bold innovation, is the development of low carbon, energy saving, environment friendly bold exploration. On the road of R290 refrigerant air conditioning production line is completed, will not only to our country and the world air conditioner industry application of environmental friendly technology play an exemplary role, will also to our country industry environment fully implement international conventions, to accelerate the elimination of R22 play a positive role.\" After R290 environmental protection air conditioning, in August 2012, gree electric appliances once again successfully developed new environmental protection refrigerant R32 air conditioning, and on November 30, 2012 global debut \"R32 environmental protection refrigerant air conditioning\" VDE certification. R32 chemical name is methylene fluoride, fluoride is a synthetic, compared with R22, R410A, the greenhouse effect is low, and more energy efficient, is a kind of harmonious balance the excellent refrigerant energy saving, environmental protection and safety. At present, because of new refrigerant r&d technology difficult problem, spreading new refrigerant air conditioners on the market is still in its infancy, gree electric as a leader in the field of air conditioning, using powerful scientific research advantage, leading the low-carbon life, with the power of science and technology to undertake the social responsibility of developing low carbon economy. In December of 2012, China industrial and commercial refrigeration industry the first as hydrogen (CFCS) out contract signing ceremony held in Beijing, gree electric appliances contributions by the United Nations recognized environmental protection, to become the Chinese electrical appliances industry first by Montreal the multilateral fund of the enterprise.
