The Ministry of industry and information technology suggested that the energy efficiency standard of air conditioning should be slowly raised to level III

the debate on upgrading the energy efficiency standard of air conditioning has made new progress. China Business News learned yesterday that the general office of the Ministry of industry and information technology sent a letter to the National Standardization Administration Committee, suggesting that the construction of copper based new material industry convergence and development base should be steadily promoted, and the entry level of household air conditioning energy efficiency standard should be raised to level 3 (3.0) rather than level 2 (3.2) according to the opinions of China Household Appliance Association

according to an internal data obtained by this newspaper recently, several major domestic air-conditioning enterprises have jointly written to relevant departments in the past few months against using the secondary energy efficiency rating as the entry threshold of the household air-conditioning market. The energy efficiency limit and energy efficiency grade of room air conditioning 2. Tls-s (10000~20000n) II fully automatic spring tension and compression testing machine revised by the China Institute of standardization under the National Standardization Administration Committee was published in June this year for comments, proposing to raise the energy efficiency limit (market access threshold) of household air conditioning from the current level 5 (2.6) to level 2 in 2009. The draft was strongly opposed by enterprises after it was published on the website, and it was withdrawn soon. Up to now, there has been no formal draft for comments on the upgrading scheme of energy efficiency standards for domestic air conditioners in China

the above internal information puts forward several reasons against "secondary access". First, the secondary energy efficiency is equivalent to the current EU highest energy efficiency grade a level. Considering that the EU allows 15% of the test error, the EU's actual class a energy efficiency is only equivalent to China's class IV (2.8) energy efficiency level. Taking higher than the EU class a energy efficiency grade as the access threshold of the Chinese market is not in line with China's national conditions; Second, after 20 years of development, China's domestic air-conditioning output accounts for about 70.8% of the world's total output, but there is still a certain gap between domestic air-conditioning enterprises and foreign-funded enterprises in technology, especially core energy-saving technology. If the entry standard is raised to level II, it will be detrimental to national industry; Third, the state proposes to build an energy-saving society, and we should take a comprehensive view of energy conservation and resource consumption. According to the existing technical level, China's air-conditioning products need to consume more copper and aluminum to reach the second level of energy efficiency. For example, 1.5 air conditioners need to consume 2.26kg more copper from the fifth level of energy efficiency to the second level. With the increase of 0.6kg of copper used by compressors, the actual increase of 2.86kg of copper used by each compressor, plus the increase of aluminum, steel The consumption of plastics, and the mining, smelting and processing of copper, aluminum and steel are high-energy consumption industries

behind the debate on air conditioning energy efficiency standards is actually a dispute of interests. In the formulation of air conditioning energy efficiency standards, some foreign companies and foreign institutions have influenced the decision-making of standard setting institutions in various ways. For example, Emerson of the United States participated in the preliminary research and drafting of three air-conditioning energy efficiency standards as the main drafting unit. The company hopes to promote the sales of its scroll compressors by formulating high energy efficiency standards. The International Copper Association and the American energy foundation have also participated in the formulation of China's air conditioning energy efficiency standards. On the contrary, domestic compressor enterprises are not qualified to participate

for the views mentioned in the above-mentioned internal materials, the relevant person of the International Copper Association (China) responded in an interview with this newspaper yesterday that the sealing strip, sunroof, door lock, seat, roof liner and process Rubber have made a great "contribution" to the VOC content of the whole vehicle: the International Copper Association does provide relevant research basis for the formulation of China's air conditioning energy efficiency standards, but the International Copper Association is based on fairness Do it from the perspective of the overall situation. The final achievement of the upgrading of air conditioning energy efficiency standards should be the result of the balance of interests of the country, the industry and the people. Whether the entry level of China's air conditioning energy efficiency standards will be upgraded to level 2 or level 3, as long as we move in this direction, the International Copper Association will support it. Yesterday, the newspaper could not contact the relevant person of Emerson

the China Institute of standardization, which is specifically responsible for the drafting of air conditioning energy efficiency standards, is reasonably used. 2. Cheng Jianhong, a researcher of the hydraulic oil and electricity Standardization Technical Committee, said to this newspaper that he was not clear about the "three-level access" proposed by the Ministry of industry and information technology. However, relevant departments have investigated it, and the specific information on the progress of standard formulation needs to wait
