On March 13, 2015, the Environmental Protection Foreign Cooperation Center of the Ministry of Environmental Protection, the China Household Electrical Appliances Association, the United Nations Environment Program, the United Nations Industrial Development Organization, and the German International Cooperation Agency jointly released the room air conditioners and heat pump water heaters in Shanghai. Logo."

It is understood that in order to comply with the development trend of international environmental protection, China's room air conditioner industry is conducting the switch of refrigerants to protect the ozone layer and deal with global warming. At present, there are major controversies at home and abroad on the choice of two major alternative technologies: One alternative route is chemical synthesis of hydrofluorocarbons (HFCs), such as HFC-410A, HFC-32, etc.; Alternative technological routes are naturally occurring substances such as propane (R290), carbon dioxide (CO2) and the like.

Although HFC-410A, HFC-32 and other synthetic refrigerants have no destructive effect on the ozone layer, most of them are greenhouse gases, which have a certain impact on global warming. At the same time, these HFCs are produced by the fluorine chemical industry, and corresponding by-products will be produced during the production process, which will have a destructive effect on the environment. From the perspective of policy analysis, from the perspectives of domestic and foreign policy trends such as the Xi'ao talks to the proposal for HFCs reduction in the three countries of North America, and the revision of the EU's fluoric gas regulations, the future fate of HFCs with potential for high-temperature greenhouse gases is worrying. The material political risks in the future are gradually increasing. From a technical point of view, HFC-32 and other weakly flammable alternatives will produce highly corrosive hydrofluoric acid after combustion or high temperature operation. This poses a great risk to human health and product reliability.

Another alternative route is the selection of natural environmentally friendly refrigerants, which is an internationally recognized environmentally friendly refrigerant with superior environmental performance. In addition, due to its superior cooling performance, the energy efficiency level of the product will also increase to some extent. Room air-conditioner products using natural environmental protection refrigerants are environmentally friendly, energy-efficient products. Although it has a certain degree of flammability, it can be properly resolved through appropriate technical means. With advanced technology, it is possible to achieve a safer level than existing products. Therefore, the alternative route for such natural and environmentally friendly refrigerants should be the future direction of refrigerant development in the room air conditioner industry.

“Environmental Low-Carbon Logos” was established in order to cooperate with the ongoing application of environmental protection refrigerant propane application and promotion in China's room air conditioner industry. “Environmental Low Carbon Logos” adapts to the current trend of environmental protection policies at home and abroad, and the main target product chosen is to use natural Environmental refrigerant products. Choosing a product with "environmentally friendly low-carbon label" and choosing a room air-conditioner product using hydrocarbon technology is equal to using actual actions to contribute to the environmental protection of China and the world.

At the same time, the release of "environmentally friendly low-carbon logos" will further standardize the definition and relevant propaganda of China's home appliance industry for environmentally friendly low-carbon products. Xiao Xuezhi, deputy director of the Environmental Protection Foreign Cooperation Center of the Ministry of Environmental Protection, said that through the release and use of logos, manufacturers will promote the production of environmentally friendly, low-carbon products, and at the same time make it easier for consumers to purchase environmentally friendly low-carbon products. "Environmentally friendly low carbon logo" was first used in China's room air-conditioner industry and heat pump water heater industry. It clearly defines the two environmental protection and low carbon theme concepts, emphasizing that logo products need to be environmentally friendly, and have no ozone layer and global warming. Impact or influence is negligible.

The characteristics of the “Environmental Low-Carbon Markers” released this time can be summarized as “one idea, two types of products, three standards, and five publishers”. A concept refers to the concept of the logo emphasizing environmental protection and low-carbon life. It hopes to leave a blue sky and green and healthy home for future generations through our actions; two types of products include room air conditioners and heat pump water heaters; The standard defines what is environmentally friendly and low-carbon products. The first criterion is that the ozone destructive potential must be zero, the second criterion is that the greenhouse effect potential must be less than 150, and the third standard is the national standard. The prescribed energy-saving products; five publishers include the United Nations Industrial Development Organization, the United Nations Environment Program, the Ministry of Environmental Protection Center for Environmental Protection, the China Household Electrical Appliances Association and the German International Cooperation Agency.

It can be seen from this that "environmentally friendly low-carbon logos" have had an international nature since their release. The internationally recognized environmental protection agency UN Environment Agency and the United Nations Industrial Development Organization jointly participated in the issuance and management of the logo. This shows that the concept advocated by the eco-friendly low-carbon logo is recognized by international authoritative environmental organizations and is an international environmental protection field. Consensus. Mr. Gannan, Secretary-General of the secretariat of the Multilateral Fund for the Montreal Protocol, attended the press conference in person and it also reflected the determination of the international community, government, industry associations and others to promote propane R290. This is also in line with the global trend of the development of China's room air conditioner industry, which has a positive role in promoting the internationalization of room air conditioners in China.

Jiang Feng, chairman of the China Household Electrical Appliances Association, said that the release of “environmental low-carbon labels” is of great significance. It is hoped that the “green and low carbon” logo will be issued to promote environmental protection concepts and further enhance public awareness of environmental protection. The most important thing is to help. The promotion of propane (R290), through the active actions and joint efforts of companies, distributors, media and consumers, choose environmentally friendly and low-carbon products to build a beautiful China for the benefit of the environment and the benefit of future generations.
