1. Overview of Energy Efficiency Test
Energy efficiency test is an independent, systematic and standardized testing process, which is used to measure, evaluate and verify the energy utilization efficiency of products, equipment, systems or facilities under specified working conditions. Its core purpose is to quantify the energy consumption level of the tested object, judge whether it meets the national, international energy efficiency standards and technical requirements, provide data support for energy conservation supervision, product quality evaluation, market access and energy-saving transformation, and promote the rational use of energy and the development of energy-saving industries.
Testing Scope:Applicable to energy efficiency evaluation of household appliances, industrial equipment, power equipment, building energy systems, lighting products, motor products and other energy-consuming products/equipment (independent of chemical testing and reliability testing, with independent testing standards and processes).
2. Core Testing Items & Methods
2.1 Basic Energy Consumption Testing
|
Testing Item |
Testing Method |
Core Purpose |
|
Rated Power Consumption Test |
Operate the product/equipment under rated working conditions, use calibrated power measuring instruments to record power values continuously for a specified time (e.g., 30min, 1h), and calculate the average rated power consumption. |
Verify whether the actual rated power consumption of the tested object is consistent with the manufacturer's nominal value. |
|
Standby Power Consumption Test |
Place the product/equipment in standby state (no load, no working operation), measure the standby power continuously for a specified time, and take the average value as the standby power consumption. |
Evaluate the energy consumption level of the tested object in standby state, and meet the standby energy-saving standards. |
|
Actual Working Condition Energy Consumption Test |
Simulate the actual use environment and working conditions of the product/equipment, measure the total energy consumption within a complete working cycle or specified time, and calculate the energy consumption per unit of work. |
Reflect the actual energy consumption level of the tested object in practical application. |
|
Load Energy Consumption Test |
Adjust the load of the equipment (e.g., 50%, 75%, 100% rated load), measure the energy consumption under different load conditions, and analyze the energy consumption change law with the load. |
Evaluate the energy efficiency performance of the tested equipment under different load conditions. |
2.2 Energy Efficiency Indicator Testing
Energy Efficiency Ratio (EER) Test: For refrigeration, air conditioning and other equipment, measure the cooling capacity and input power under standard working conditions, and calculate EER = cooling capacity / input power. The higher the value, the better the energy efficiency.
Coefficient of Performance (COP) Test: For heat pump, refrigeration and heating equipment, measure the heating/cooling capacity and input power, and calculate COP = heating/cooling capacity / input power, which reflects the energy conversion efficiency.
Energy Efficiency Grade Test: Based on the measured energy efficiency indicators, compare with the relevant standard limits, and determine the energy efficiency grade of the tested product/equipment (e.g., Grade 1 to Grade 5, Grade 1 is the most energy-saving).
Energy Saving Rate Test: Compare the energy consumption of the tested object before and after energy-saving transformation (or with the reference product), and calculate the energy saving rate = (original energy consumption - improved energy consumption) / original energy consumption × 100%.
2.3 Special Energy Efficiency Testing
Lighting Products: Test luminous efficacy (lm/W), luminous flux, power factor, color temperature and other indicators to evaluate lighting energy efficiency.
Motor Products: Test motor efficiency, power factor, rated speed and other indicators under rated working conditions, and judge the energy efficiency level.
Building Energy Systems: Test the energy consumption of heating, ventilation, air conditioning (HVAC) systems, measure the energy utilization efficiency of the whole building, and evaluate the building energy efficiency level.
3. Core Evaluation Indicators
The energy efficiency evaluation is based on the following core indicators, and the specific limit values shall comply with relevant national/international standards and product technical specifications:
Energy Efficiency Ratio (EER): Applicable to refrigeration and air conditioning equipment, the minimum limit is specified according to the product type and standard, and the higher the value, the better the energy efficiency.
Coefficient of Performance (COP): Applicable to heat pump and heating equipment, reflecting the energy conversion efficiency, and the limit value is specified according to the working conditions and product specifications.
Energy Efficiency Grade: Divided into multiple grades (generally 3-5 grades) according to the standard, Grade 1 indicates the highest energy efficiency (minimum energy consumption), and Grade 5 indicates the lowest energy efficiency (maximum energy consumption).
Standby Power Consumption: The maximum limit is specified according to the product type (e.g., household appliances generally require standby power ≤ 1W), which shall not exceed the standard requirement.
Unit Energy Consumption: Energy consumption per unit of output (e.g., kWh/100km for vehicles, kWh/kg for industrial products), which shall be lower than the standard limit.
4. Standard Testing Workflow
Test Preparation: Confirm the tested product/equipment information, clarify the test standards and requirements, select calibrated energy measuring instruments (power meter, energy meter, etc.), simulate the standard working conditions (temperature, humidity, load, etc.), and check the instrument operation status.
Sample Preparation: Inspect the appearance and performance of the tested sample to ensure it is in normal working state, record the manufacturer's nominal parameters (rated power, energy efficiency grade, etc.), and place the sample in the specified test environment for preheating/stabilization (if required).
Test Execution: Carry out the test in accordance with the preset test plan and standard methods, strictly control the test conditions, measure and record the test data (power, energy consumption, working time, etc.) in real time, and repeat the test 2-3 times to ensure data reliability.
Data Processing: Sort out and verify the test data, eliminate abnormal values, calculate core energy efficiency indicators (EER, COP, energy efficiency grade, etc.), and conduct error analysis to ensure the accuracy of the data.
Result Evaluation: Compare the calculated energy efficiency indicators with the relevant standard limits and the manufacturer's nominal values, judge whether the energy efficiency of the tested object meets the requirements, and put forward clear evaluation opinions.
Report Issuance: Compile the test report, attach the test records, instrument calibration certificates and other relevant materials, issue the CMA/CNAS certified report (if applicable), and ensure the authenticity, completeness and traceability of the report.
