How is the energy efficiency level of smart home appliances evaluated?

The energy efficiency rating of smart home appliances is actually a scientific and rigorous process. It is based on a series of testing and assessment standards, which are usually established by national or international organizations. In China, the evaluation of the energy efficiency levels of smart home appliances follows the “China Energy Efficiency Label Management Regulations” and relevant national standards, such as GB 12021.3-2013. These standards stipulate the energy consumption requirements of home appliance products under different working conditions, as well as testing methods and conditions.

During the evaluation process, home appliance products are first tested for energy efficiency, including but not limited to key indicators such as power consumption, power factor, and standby power consumption. Then, based on the test results, the products are classified into different energy efficiency levels. Generally, the energy efficiency levels range from level 1 to level 5, with level 1 indicating the most energy-saving and level 5 indicating relatively higher energy consumption. This grading method not only helps consumers to intuitively understand the energy-saving performance of the products but also encourages manufacturers to continuously optimize their products and improve energy efficiency.

As far as I know, in recent years, with the continuous advancement of technology and the strengthening of consumers’ energy-saving awareness, the energy efficiency levels of smart home appliances have generally improved. According to statistics, the market size of China’s smart home appliances reached about 450 billion yuan in 2019 and is expected to exceed 700 billion yuan by 2023. In this process, the proportion of smart home appliance products with high energy efficiency levels has been increasing year by year, which not only reflects the market demand but also represents the progress of our industry.

However, the evaluation of the energy efficiency levels of smart home appliances is not static. With the development of technology, new testing methods and standards are also continuously updated. For example, with the application of Internet of Things technology, the evaluation of energy efficiency of smart home appliances also begins to consider the energy consumption performance of products under intelligent control. This requires us to keep learning and adapting to ensure that our evaluation system can keep pace with the times and truly reflect the actual energy efficiency of the products.

Finally, I would like to quote an ancient saying: “To do a good job, one must first sharpen his tools.” In the smart and new energy industry, our “tools” are technology and standards. Only by continuously optimizing these “tools” can we better serve society and achieve green and sustainable development. Thank you, everyone!
