1、 Clear evaluation policy and scope

The policy and scope of clear evaluation of requirements include determining the type, quantity, and application scenarios of electrical equipment to be evaluated, as well as detailed policies for evaluation (such as energy efficiency ratio, power factor, energy utilization rate, etc.).

2、 Collect device information

Technical parameters: Collect basic parameters such as rated voltage, rated current, rated power, and power of electrical equipment.

Operation data: The actual operation data of the equipment is obtained through on-site monitoring or data collection system, including input power, output power, operation time, etc.

Environmental conditions: Understand the environmental conditions in which the equipment is located, such as temperature, humidity, altitude, etc., as these factors may affect the energy efficiency of the equipment.

3、 Select evaluation methods

Based on functional evaluation: By measuring the input power, output power, and other parameters of electrical equipment, the energy efficiency of the equipment can be directly calculated. This method is suitable for most electrical equipment, especially those with clear input-output connections.

According to the evaluation of the model, it is possible to establish mathematical models to predict the energy efficiency of complex electrical systems under different operating conditions. This approach requires consideration of various influencing factors such as the dynamic characteristics of the system and environmental factors.

Based on comparative evaluation: Compare the energy efficiency of the policy equipment with similar equipment and evaluate its energy efficiency level. This method helps to understand the position and direction of the equipment in the same industry.
