Application of Fan Energy Efficiency Testing System

Customer Background

The customer is a manufacturer specializing in the design, production, and export of electric fans, including table fans, floor fans, tower fans, and ceiling fans. Their products are sold to domestic and international markets, where compliance with energy efficiency regulations and performance certification is a key requirement.

With increasing global demand for energy-saving appliances, the customer needed a more advanced and standardized testing system to support product certification, R&D optimization, and production quality control.

Customer Challenges

Before implementing our system, the customer faced several critical challenges in fan performance testing:

1. Lack of Unified Standard Testing Platform

Testing activities were previously fragmented across different setups, making it difficult to ensure full compliance with:

IEC 60879:2019

GB/T 13380-2018

GB 12019-2008 (Energy Efficiency Limits and Grades for AC Electric Fans)

This led to inconsistent test procedures and difficulties in certification reporting.

2. Low Measurement Efficiency and Manual Operation

Airflow and energy efficiency testing required multiple manual adjustments, resulting in:

Long test cycles

High operator dependency

Reduced throughput in laboratory testing

3. Limited Measurement Stability and Repeatability

Existing systems showed instability in long-term testing, including:

Airflow fluctuation

Environmental influence (temperature/humidity variation)

Inconsistent repeatability across test batches

4. Data Management Limitations

Test data was not fully automated, leading to:

Manual recording errors

Limited traceability

Inefficient data export for reports and certification

Our Solution

To address these challenges, we provided a Fan Energy Efficiency Testing System designed for high-precision airflow measurement and full compliance with international and national standards.

1. Standards-Compliant Testing Architecture

The system is designed in strict accordance with:

IEC 60879:2019

GB/T 13380-2018

GB 12019-2008

It automatically evaluates whether tested fans meet energy efficiency requirements and regulatory thresholds.

2. High-Precision Integrated Testing System

The system integrates multiple measurement functions, including:

Air volume (airflow)

Temperature and humidity

Rotational speed (RPM)

Voltage, current, and power

This enables full performance characterization of electric fans in one unified test environment.

3. Advanced Control System Architecture

The system consists of a chamber body, test screen, control system, and airflow acquisition system, featuring:

Mitsubishi PLC (Japan) control system

Industrial PC-based control platform

17-inch touchscreen HMI interface

This ensures stable operation, intuitive control, and real-time data visualization.

4. XYZ Three-Axis Motion Control System

The system supports automated mechanical positioning with:

Adjustable movement distance

Variable speed control

Adjustable test height

This significantly improves testing flexibility for different fan types and sizes.

5. Automated Data Acquisition and Storage

All test data can be:

Automatically recorded

Stored in the system database

Exported via USB

This ensures full traceability and supports certification documentation requirements.
