碳效比在变频调速设备低碳评价方法中的应用OA

In the context of China's"carbon peaking and carbon neutrality goals",the electrical equipment manufacturing industry urgently needs a low-carbon transition.As a key component of electrical equipment,variable-frequency drive(VFD)devices offer significant advantages such as precise regulation,notable energy savings,flexible control,and excellent equipment protection.These attributes make VFDs highly valuable in industrial automation and energy efficiency management.However,the industry currently lacks technical parameters for low-carbon evaluation that align with the functional contributions of these products.The concept of carbon efficiency ratio(CER)was introduced through a case study to illustrate its application in the low-carbon evaluation of electrical equipment.For accurate and comprehensive assessment,the carbon footprint of products was calculated using a cradle-to-grave life cycle approach.By comparing CER data of VFD devices of different specifications and various types of electrical equipment,it was demonstrated that a lower CER indicates lower carbon emissions for the same functional contribution,thus reflecting higher low-carbon performance.The introduction of the CER concept enables more accurate evaluation of the low-carbon performance of VFD products,aids in establishing low-carbon evaluation standards for the industry,and facilitates the electrical equipment industry's achievement of the"dual carbon"goals,while also providing insights and references for low-carbon transitions in other industries.
