The energy efficiency labeling system was launched on March 1, 2005. The newly revised "Energy Efficiency Labeling Management Measures" came into effect on June 1, 2016, simultaneously repealing the 2004 version. According to these regulations, all household air conditioners manufactured, sold, or imported in China must be labeled with an energy efficiency rating; otherwise, they are not allowed to be sold on the market. The energy efficiency label includes a QR code, which can be scanned to view detailed energy efficiency information.
After the implementation of the new policy, high-energy-consuming products have been phased out of the market. Energy-saving and inverter products now dominate the market. Furthermore, with the continuous launch of new air conditioner products by manufacturers in recent years, there are increasingly more options in terms of appearance, function, and price, meeting the purchasing needs of different users. Whether an air conditioner is energy-efficient has always been a focus of attention for users. When actually purchasing, many consumers will certainly want to know how to determine the energy efficiency of an air conditioner-is it the energy efficiency rating or the energy efficiency ratio? What is a standard?
In fact, both energy efficiency rating and energy efficiency ratio are terms used to assess the energy efficiency of an air conditioner. After the implementation of the new policy, the energy efficiency limit value in the new energy efficiency standard has increased by about 23%. Among them, the energy efficiency limit value of split room air conditioners with a rated cooling capacity of less than or equal to 4500W is 3.2, that of rated cooling capacity greater than 4500W and less than or equal to 7100W is 3.1, and that of rated cooling capacity greater than 7100W and less than or equal to 14000W is 3.0. Energy efficiency is divided into five levels (level 1 to level 5), with level 1 being the best and level 5 being the market access standard . This is how to select energy-saving air conditioners based on energy efficiency level. The so-called energy efficiency ratio is the numerical value in the table. According to the current standard, the value of the energy efficiency ratio of level 1 is usually above 3.4. For specific values, refer to the energy efficiency index on the energy efficiency label .
The energy-saving performance of air conditioners is usually measured by the annual performance factor (APF). The higher the APF value, the more energy-saving. When purchasing, attention should be paid to the APF value and other performance indicators (such as cooling capacity and heating capacity). Inverter air conditioners operate at a stable low frequency, making them more energy-efficient than fixed-frequency air conditioners that repeatedly start and stop. They also offer more precise temperature control and lower energy consumption over extended periods. Therefore, consumers can choose energy-efficient products based on their specific needs and requirements.
