Two days ago, when we introduced Xiaomi air conditioner, we mentioned the 'Energy efficiency grade' and also calculated the product management of air conditioners with different energy efficiency grades

'My name is 'China energy efficiency identification''. According to the 'scientific popularization' routine, the first thing is to introduce the 'sticker. The official name of this blue and white sticker is called 'China Energy Efficiency logo ( China Energy Lable)'Is a mandatory product certification information. The 'sticker' style and the information displayed are also stipulated, according to the latest standards, this 'sticker' should include the name or abbreviation of the producer, product specification and model, energy efficiency grade, energy efficiency index, mandatory national standard number of energy efficiency and energy efficiency information (Two-dimensional)Code 6 information. Among them, the 'Energy efficiency index' item, according to different product categories, the marked index items will be different, for example, the air conditioner marked the cooling season power consumption and other indicators, the refrigerator displays information such as comprehensive power consumption, and the printer is a typical energy consumption. As a mandatory product standard formulated by the country, the role of 'energy efficiency grade' is not difficult to understand. It can promote enterprises to invest in product energy-saving technologies and produce products with higher efficiency and lower energy consumption, on the premise of ensuring that consumers have enough choices, improve the overall interests of consumers, and from a higher perspective, energy conservation is also in line with the overall interests of all mankind. Some Western countries implemented energy efficiency standards earlier than China, which generally started from 1960s to 1970s. For example, Poland formulated the first set of energy performance standards in 1962, france formulated the energy efficiency standard of refrigerators in 1966, while the United States enacted the National Energy Conservation Policy Act in 1978, and since 1980, it has implemented mandatory energy efficiency labels on a series of industrial products, the EU is 1992. Among them, the US Energy Conservation Act is also regarded as the first standard that has a greater impact on manufacturers and significantly promotes energy consumption reduction. The formulation of China's energy efficiency standards began in 1989 and was enforced in December 1, 1990. The competent department is the energy efficiency label Management Center under the Resource and Environment Branch of China Institute of Standardization. The energy efficiency standard has been revised several times, and the latest revision in 2016 is currently being implemented. The 'stickers' you see on various electrical appliances are also based on this standard. At present, the energy efficiency management standard in 2016 covers 35 categories of products, including common household appliances such as televisions, washing machines, refrigerators, air conditioners, household gas stoves, etc, there are also computers, monitors, copiers/printers and other products, as well as some commercial and industrial electrical products. However, different categories of products have different standards for energy efficiency rating. Each category of products has a set of implementation rules, and the indicators for energy efficiency rating in different rules are also quite different. How does this 'sticker' look at the use of energy efficiency signs, naturally need to read the signs. In addition to the energy efficiency level, the most valuable nature is the energy efficiency index. However, when testing these products, there may be many indicators, such as GB 12021 implemented according to refrigerators. 2- 2015 Standard, items that need to be tested include volume, storage temperature, total adjusted volume, reference power consumption, power consumption limit value, standard power consumption, comprehensive power consumption, standard energy efficiency index and comprehensive energy efficiency index, however, it is impossible for all this information to be displayed on a small 'sticker', so what is displayed on the 'sticker' is only the most intuitive and easy-to-understand indicator. For example, the refrigerator can refer to 'comprehensive power consumption', which simply refers to the power consumption of the refrigerator for 24h under loading conditions, of course, many other variables will be added in the experimental process to simulate the real use environment as much as possible. For example, the indexes worthy of reference on air conditioners are 'power consumption in cooling season' and 'power consumption in heating season ', these two indicators have been introduced in the article 'grasping the tail of summer, Mijia internet Air Conditioning. For most people, I think the information on the 'sticker' is enough for reference. On the new energy efficiency logo implemented on 2016, there is also a two-dimensional code, which can be used to obtain more detailed authentication information of the product by using WeChat or the browser's code scanning function. If you have spare capacity or are interested in learning more about these indicators, you can know how the national standards define various indicators by searching for 'mandatory national standard number for energy efficiency' under 'stickers, how to design the experimental link. We also put a link to detailed information here, where you can find the product catalog of the People's Republic of China implementing the energy efficiency logo (2016 Edition) 'Basic style of China's energy efficiency logo' (Revision)And other information. Finally, we return to the question of 'choosing first-class energy efficiency or third-class energy efficiency'. In fact, we can know through understanding the 'Energy efficiency Logo, the 'energy efficiency level' does not indicate 'qualified or unqualified', but the relative energy consumption level of each product in the 'qualified product. In other words, you can understand Level 3 or level 5 energy efficiency ( In the standard revised in 2016, some products were adjusted to level 3, while others were still level 5) It is already a qualified line for product energy efficiency performance. As long as this 'sticker' is attached, it is a qualified product. So before you decide what to buy, there are many factors worth considering besides the energy efficiency level.
