Increased requirements for energy-efficient products

In addition to the adjustment of the scope of application, another major change is that the standard has re-divided the energy efficiency levels. The requirements for energy efficiency levels 1 and 2 have been increased, and the requirements for energy efficiency level 3 have been improved. The energy efficiency standard for electric fans divides the energy efficiency rating into 3 levels. Energy efficiency level 1 is the target value, products that meet the energy efficiency level 1 requirements are advanced and efficient products, and level 3 is the energy efficiency limit value. Products below the energy efficiency limit value index will be prohibited from being produced and sold. According to a drafter of the standard, according to the energy efficiency limit value of the current GB 12021.9-2008 standard, about 50% to 70% of the products on the market can reach energy efficiency level 1 and 2. The share of energy efficiency level 1 and energy efficiency level 2 products of general energy efficiency standards should not exceed 20%, so it is necessary to improve energy efficiency requirements. According to him, the standard energy efficiency level 3 requirements have not been improved much, and about 5% to 10% of products on the market will be eliminated.(egg cooker)

According to the standard preparation instructions, during the standard revision process, the drafting team collected data on the energy efficiency percentages of the products sold at all levels. The data shows the proportion of the sales of products at all levels according to the energy efficiency grades of the 7 major companies according to the standard consultation draft. The products of other companies that are not counted are mostly energy efficiency level 3 or below.(egg cooker)

The reporter of “Electrical Appliances” learned that this standard revision will cause major changes in the product structure of the electric fan market, mainly because the original energy efficiency level 1 and energy efficiency level 2 products, many of which will become energy efficiency level 3 products. However, according to corporate feedback, it is not difficult for mainstream companies to achieve new energy efficiency level 1 and energy efficiency level 2, but product costs may increase.(egg cooker)

In addition, the revision of the energy efficiency standards for electric fans has also increased the standby power limit. The standby power of the electric fan with standby function, the electric fan with information or status display function, the electric fan products with energy efficiency grades 1 and 2 must not exceed 1.8W, and the standby power of products with energy efficiency grade 3 must not exceed 2.0W; For products with no information or status display function, the standby power of energy efficiency grade 1 and 2 products is not allowed to exceed 0.8W, and the standby power of energy efficiency grade 3 products is not allowed to exceed 1.0W. (egg cooker)

Due to the particularity of products with Wi-Fi and IoT functions, their standby power will be higher than that of products with ordinary standby functions. Therefore, this standard does not specify their standby power. During the interview, the interviewees agreed that this revision is of great significance. China is a big country in the manufacture of electric fans, with an annual output of about 80 million units. Based on an average life span of 10 years, the market has about 800 million units.(egg cooker)

Therefore, the revision of energy efficiency standards will have significant effects on energy conservation and emission reduction. At the same time, the standard will also provide technical support for the promotion and application of energy-saving electric fans, further promote the optimization and upgrading of the industrial structure, guide and standardize the development of electric fan product technology, and enhance the advancement, rationality and applicability of the standard. Improving its technical level plays a key supporting role.(egg cooker)
