Product Energy Efficiency Standards and Labeling Methodology, Beijing Energy Efficiency Center Xinding Guo Zhu Yuezhong Generally speaking, the procedure for formulating a complete energy saving standard for household appliances should include the following steps: Deciding to formulate energy efficiency standards, determining the standards setting institutions, establishing testing procedures, and establishing Testing laboratories, conduct energy efficiency analysis and establish energy efficiency standards, implement energy efficiency standards, and supervise implementation effects and effect evaluation. To set standards, you must first establish a test program to test the energy efficiency level and power consumption of home appliances. The implementation of the energy efficiency labeling program is mainly to guide consumers to purchase efficient home appliances, but it is not absolutely necessary for the formulation of energy efficiency standards. Once the test procedure has been determined, energy efficiency standards can be developed by statistical analysis methods, engineering analysis methods, or other methods such as Japan using a method that listens to most opinions. After the standards are developed, appropriate institutions and measures are needed to ensure the implementation of energy efficiency standards.
A key step in developing standard process development standards is to establish test procedures for related products. Test procedures, sometimes referred to as test protocols, provide a means of determining the energy and energy efficiency levels of a product. Some test procedures also provide methods for determining product performance, such as the amount of laundry in a washing machine or the ability to freeze food in a refrigerator. Establishing a test program has two purposes: to properly classify product models based on energy efficiency values; to provide a relatively accurate estimate of the actual power consumption of home appliances.
At present, the testing procedures for home appliances in different countries are different. The EU mainly uses international testing procedures developed by the International Organization for Standardization and the International Electrotechnical Commission. However, the EU sometimes uses these modified international test procedures, and it also has its own measurement system that is inconsistent with and. The United States has a set of testing procedures developed by the US Department of Energy. Test procedures in Canada and Mexico are similar to those in the United States, but they differ from each other. Some other countries use test procedures, and some have their own test procedures.
It can be seen from the above that for the significant differences in the test procedures of the same product, it is impossible to compare the energy consumption data obtained from different countries according to different test procedures. At the same time, these differences have also affected the import and export trade of household electrical appliances.
