This standard will be China's "220V Cooling Fan" energy efficiency standards for energy efficiency rating is divided into three. An energy-efficient, is the target, only less than 5% of the product to achieve an energy efficiency level; two for the energy evaluation value, currently about 20% of the products reach the two levels of energy efficiency; 3 for the energy efficiency of limited value, Currently about 65% of "220V Cooling Fan" to achieve three levels of energy efficiency, while another 10% of the products of the energy efficiency requirements defined value of less than 3, the manufacturers need to improve this part of the product. Energy efficiency limit is the minimum standard AC fan under test conditions to allow the value of energy efficiency, is the mandatory targets, industry management, to prevent low energy efficiency of "220V Cooling Fan" into the market, according to eliminate high energy-consuming products. After the standards, less than three products for the phase-out of products, to prohibit their production and sales.
